Off-Grid Solar Panels to Last a Lifetime

Our portable solar kits are the most flexible and efficient solar option. With the largest selection of portable kits on the market, you’re sure to find a solution that works for you.

Made in the USA:

Our panels are handcrafted in Bend, Oregon using the finest materials available (locally sourced whenever possible.) They are built to last 25 years or more and every panel is signed by the person who made it and tested it.

So instead of saving a few bucks now and buying a new solar kit every couple of years, invest once and charge with confidence for the next couple of decades.

Remove From Case and Unfold.

Unzip the bag and pull out the portable panel. Open the clasp and unfold the panels (except for the 45-watt portable, which is a single panel).

Pull out Legs and Set Up the Panel.

Pull out the support legs and set the panel out in direct sunlight. The panel will sit at an angle and should face the sun as directly as possible for maximum efficiency.

Connect the Panel to Your Solar Port or Battery.

Use the included SAE port to plug the kit into a Zamp Solar Ready port, or use the included alligator clamps to connect directly to the battery.

Plug & Play with Zamp Solar Ready Ports:

Most newer RV’s come with a Zamp solar port on their wall or roof. If you have one, you can just plug the panel in with the included SAE cable and start charging!

No port? No Problem!

Use the included alligator clips to attach your portable kit to any kind of 12-volt battery or battery bank (including lithium).

Got a different solar port?

Check out our Furrion adapter.

Includes Everything

Our portable solar kits include everything you need to charge a 12-volt battery or battery bank, including the panel, charge controller, wires, and connectors.

Durable Carrying Case

Every portable comes in a rugged nylon carrying case with thick padding to protect the panel when it’s not in use.

Charge Controller on EZ-View Bracket

A weather-resistant, 5-stage digital charge controller is integrated into the panel to protect your battery and mounted on an EZ-view bracket for convenient monitoring.

User questions & answers

Question:	Is there a way to adjust the float voltage on this unit
Answer:	No, the float voltage on mine is 13.8V no matter the battery type setting. There is a manual on the Renogy website that lists float at 13.2V when set for Flooded batteries. However that is not the case on my unit, which I bought in 2016.
Question:	Can anyone explain the middle led's lighting sequence? What are the possible states of display, blinking, on, what do they mean
Answer:	The middle LED's lighting sequence is as follows: Green ON when battery level is in the right range. Green slowly flashing when battery level is full. Yellow ON when battery level is low. Red ON when loads cut off. Hope this helps.
Question:	max number of 100w panels for this controller
Answer:	This will depend on 2 things: 1 - what is the amp rating of your controller. &. 2 - what is the nominal voltage output of the panels. A 30 amp controller can handle a maximum of 3.6 100 watt panels of 12 volts (100 watts / 12 volts = 8.33 amps, 30 amp controller / 8.33 amp panel = 3.6 panels per controller). Of course, you can't have .6 panels so the safest load would be 3 panels. Yes, math is VERY IMPORTANT when being safe with electronics.
Question:	The description says "These are Positive Ground Controllers." How do you ground a system on the positive side
Answer:	Please ignore this if you're not interested in a dissertation on grounding. First, THIS is a NEGATIVE "ground" controller, so that's GOOD. Why? "Ground" is a misleading term. I've designed stuff for NASA spacecraft that had connections called "ground". Whaaat? We're going to run an extension cord to the spacecraft, so we can keep it tied to a metal pipe stuck in the dirt? Nope. "Ground" is just what electronics folks usually call a COMMON POINT the circuitry is referenced to. It doesn't necessarily have anything to do with the ground we walk on. Electrical stuff works by having two sides, positive and negative, with a voltage difference between them, the "pressure" that makes current flow. Electrical power folks tie one side to the dirt your house sits on, for safety. Your house has water pipes and stuff that's pretty well connected to the dirt. If you grab a water pipe and the 110V ground at the same time there's no voltage difference, so current doesn't flow through you and hurt you. 110V is 10x higher than a solar panel voltage so it's a lot more dangerous. Tying one side to the dirt was a very good idea. Long, long ago, and far, far away, electrical power folks chose the negative side to connect to the dirt, and most stuff made since has pretty much matched that. Then some folks decided to make "positive ground" devices, because for their designs it was easier and cheaper. Some of us think they should have been spanked. It caused all this "positive ground" and "negative ground" malarkey. On to solar power systems. Think of it like this: A controller has electronically controlled switches in it. One switch connects the solar panel to the battery to charge it and disconnects when the battery is full. Another switch connects the load to the battery when you want the load turned on. In a "negative ground" system, the terminals of the panel, battery and load called "minus" or "negative" are all tied together, and the controller switches the positive side connections. Since many loads are connected together on the minus side to ground (dirt) this is a GOOD THING. In a "positive ground" system it's the opposite. The positive side of everything is tied together, and the controller switches the negative side connections. Imagine this: If you connect the battery negative terminal and the load negative terminal both to ground (shorted together) and the controller switch is between them, what happens when the switch opens? That's right, NOTHING. The switch is shorted out by your ground connections so it can't disconnect the load. So that's what's wrong with a positive ground controller. Everyone is used to tying negative together and to ground and they do that and it screws up the controller. But a positive ground controller can be used as long as you don't connect the battery and panel to *anything* except the controller. For example, your van's battery negative is connected to the chassis of your van, and so are the negative sides of all the lights and devices in your van. JUST DON'T TIE THE SOLAR PANEL OR SOLAR BATTERY NEGATIVES TO YOUR VAN CHASSIS TOO. You CAN tie the controller's load output negative to your van chassis, as long as you don't connect any. other. point. in the solar charging system to chassis too. With a "negative ground" controller you don't have to worry about any of this malarkey. You can tie the battery, panel, load negatives all to chassis without any problems. This is why NEGATIVE GROUND CONTROLLERS ARE BETTER. Sorry for the lengthy explanation. I hope folks can follow this and it helps them understand this "ground" stuff.

User questions & answers

Question:	Can I hook up a 750 watt inverter to the Load terminals of the controller
Answer:	No you cannot. As previously stated, I’d hook the inverter straight to battery although you can hook a relay in series between the battery and inverter and use the controller load to power the coil of the relay. This will allow the controller to shut down the inverter in case of any problems. Use a relay rated for at least 70Amps for a 750 watt inverter.
Question:	Can you set this to charge the battery once it gets to a certain level
Answer:	It will charge the battery and taper off when the battery is fully charged. It won't charge a dead battery or work well if the battery is in a low charge state.
Question:	Can this controllers output voltage be set to 24 vdc? i need to series two twelve volt batteries and supply a system with 24 vdc
Answer:	The information on specs are unclear but it does work. I have two 12 volts in series on my boat in flat storage with no electrical around. I bought one 24V solar panel, connected to this controller and it works great. The serttings are automatic if you follow directions. Here is my summary for my fishing club: There’s math involved to determine solar panel size so hang in there. Each battery is 12 Volts rated at 90 amp hours (AH). Multiply volts times amps to get total watts. 12V X 90ah = 1080 watts each, times 2 batteries = 2160. That’s total watts from zero to full charge. Since you can’t run batteries to zero and expect them to work, only half of the power is usable. Therefore, my needs are half of the 2160 total = 1080 watts. I decided I wanted to get fully charged batteries after 2 days. There is good sunlight on my location an average of 6+ hours per day so I need a panel large enough to reach 1080 watts in 12 hours charging time. Watts divided by hours, 1080/12 gets me my panel size of 90. Solar panels and connections are subject to voltage loss due to dust, connections, shadows, etc. Figure 20%. I need 120 watts output in a 24-volt panel (match my battery voltage). I found the components below. A 24 volt, 150-watt panel, a controller (don’t want to overcharge) and special solar wiring and connectors all on Amazon.
Question:	Ok asking my question again. .... How many working amps? Didn't know children answered these too. Lol
Answer:	I think Dana is a little confused regarding the requirement for HEAVY gauge wires at 20 amps (as in "the wire would be too big for the controller connection screws"). 20 Amps at 12 volts is only 240 watts. (Meanwhile, 20 Amps at 110 volts is 2,200 watts, which WOULD require a heavy gauge wire.) You can easily attach a wire capable of handling 240 watts to this controller. I use this controller with three panels installed on the roof of my RV. (One 50-watt panel and two 160-watt panels, connected in parallel, for a total potential of 370 watts.) The controller works great, allowing for perpetual wilderness camping without running down my RV coach batteries over multiple days - even when using a heated Bi-Pap (CPAP) machine all night long using a 120v Inverter. I've seen this controller charge the batteries with 16.8 Amps at 13.7 volts (230.16 watts) with no issues or "hot wires". Dana debunks the controller for feeding 2.6 volts at 1 amp back into the solar panels. That's a whopping 2.6 watts, which is inconsequential next to two deep-cycle coach batteries connected in parallel. Besides, that's what blocking diodes are used for.

User questions & answers

Question:	What is the default battery type setting if I choose to plug and play without messing with the blutooth app or an additional control module
Answer:	AGM. That being said, the app takes about 20 seconds to set up and use, so it's worth the time.
Question:	what's the maximum load wattage I can put on this? I know the max charge current is 20a, but is the load fused, or just pulls from battery
Answer:	To correct multiple incorrect answers on this question: The fuse is to protect the charge controller from reverse battery connection: it DOES NOT protect the load output, nor does it protect the charging circuit to the battery, nor does it protect the PV input. Please see the user manual available at victronenergy.com/support-and-downloads/manuals.
Question:	When using an a/c battery charger/converter, do i hook it's output to the load side of the controller
Answer:	You can have multiple charging inputs to the batteries. They will work just fine independent of each other. Typical motorhome has alternator, inverter/charger and solar charger connected.
Question:	The item i received says 48v on the side. will it work with 12v/24v systems
Answer:	Even though the mppt has the 48V stamp, it will work with 12V 24V & 48V systems. The 48V is to differentiate it from the 12V/24V only mppt. Here is documetation from Victron showing it will work with all three Voltages. https://www.victronenergy.com/upload/documents/Datasheet-SmartSolar-charge-controller-MPPT-75-10,-75-15,-100-15,-100-20_48V-EN.pdf

User questions & answers

Question:	Does this take care of the function of the victron batteryprotect? it seems so but just want to make sure. thanks
Answer:	your solar can have a VOC up to 100 volts and then it will drop it down to 12 or 24 volts to charge the battery bank.
Question:	Can I have much higher input (nominal voltage of 24v) into this unit and have the unit charge a 12v battery bank? 36v->unit->13.5v
Answer:	The single difference between them is that the SmartSolar MPPTs have Bluetooth built-in so that you can monitor and configure them through the VictronConnect smartphone app. The BlueSolar MPPTs do *not* have the Bluetooth built-in; you can use a VE.Direct to Bluetooth Dongle to achieve the same functionality, but the cost of a SmartSolar ends up a little less (typically) than a BlueSolar MPPT +a VE.Direct to Bluetooth Dongle, so it usually makes more sense to order the SmartSolar. If you're not planning on monitoring the MPPT or changing any of the settings, however, a BlueSolar will be just fine, as the actual circuitry is virtually identical. Regards, -Justin Mobile Power Pros / Bay Marine Supply
Question:	what is the difference between smart solar and blue solar
Answer:	The charger will compensate for temperature based on it's internal sensor, essentially gauging the local environment's temperature. An option Smart Battery Sense can be attached to the battery for true battery temperature. Those are new and in short supply, but should be fully available by the end of June, 2018.

User questions & answers

Question:	will this work with my current 10-amp furrion solar port
Answer:	Yes. It comes with cables to connect into the solar port
Question:	Does this include the cable needed for solar ready rv’s
Answer:	I can't be sure because I don't have a solar ready RV, but they do have a plug they sell that can be mounted to RV's and wired in to the electrical system. It seems reasonable that this plug is the same in solar ready RV's, it's a common SAE connector.
Question:	Can this be used when Generator is running
Answer:	Technically speaking, the generator and solar would both be connected to the battery bank positive and negative terminals. If it is daytime, the solar charging system has a specific output voltage. It is possible that if you choose to operate a generator at the same time, the controller for the generator output voltage may be different that the solar output. When there is a difference in potential, there is additional current flow from the highest voltage to the lower voltage source. This inter-system current exchange may or may not cause additional problems between controllers. A conservative approach may be to separate the solar system when you choose to operate the generator. That is what choice I make, as I have both systems too.
Question:	Do i need anything else if i already have the zamp hookup and solar installed on my airstream. can i use this for additional charge capabilities
Answer:	This is a complete solar system. It includes the panel, charge controller and wires. The charge controller regulates the power from the solar panels to the battery. Without a good charge controller, it would be too much power and damage the battery by overcharging it. If you have a Zamp sidewall port on your Airstream, all you have to do is remove the battery alligator clips this portable comes with and reveal a 2-pin plug that will go into your solar port on your RV. You can use this to supplement power when charging form other sources or you can use this by itself. It's a powerful unit and should do the job for most typical RV'ers with RV's up to 30-feet or so.

Off-Grid Solar Panels to Last a Lifetime

Our portable solar kits are the most flexible and efficient solar option. With the largest selection of portable kits on the market, you’re sure to find a solution that works for you.

Made in the USA:

Our panels are handcrafted in Bend, Oregon using the finest materials available (locally sourced whenever possible.) They are built to last 25 years or more and every panel is signed by the person who made it and tested it.

So instead of saving a few bucks now and buying a new solar kit every couple of years, invest once and charge with confidence for the next couple of decades.

Remove From Case and Unfold.

Unzip the bag and pull out the portable panel. Open the clasp and unfold the panels (except for the 45-watt portable, which is a single panel).

Pull out Legs and Set Up the Panel.

Pull out the support legs and set the panel out in direct sunlight. The panel will sit at an angle and should face the sun as directly as possible for maximum efficiency.

Connect the Panel to Your Solar Port or Battery.

Use the included SAE port to plug the kit into a Zamp Solar Ready port, or use the included alligator clamps to connect directly to the battery.

Plug & Play with Zamp Solar Ready Ports:

Most newer RV’s come with a Zamp solar port on their wall or roof. If you have one, you can just plug the panel in with the included SAE cable and start charging!

No port? No Problem!

Use the included alligator clips to attach your portable kit to any kind of 12-volt battery or battery bank (including lithium).

Got a different solar port?

Check out our Furrion adapter.

User questions & answers

Question:	Can you send the performance history to your computer
Answer:	Yes, the app will create a .csv file that can be sent to your computer via email, bluetooth, etc.
Question:	Are these chargers able to stop charging if the battery reaches a defined voltage (over-voltage protection
Answer:	The Victron charges have a sophisticated charging method that uses three states. The final one, called a float charge reduces the current to a trickle at a safe battery voltage.
Question:	What is the manufacturer warranty on this item? Please provide link
Answer:	The boxes have a sticker - 5 year warranty, but i'll be darned if i can find a link for ya. (I have the 100/30A, and 150/60A units). wish you well.
Question:	I have flat plate agm batteries, but the only settings are for gel and spiral agm. what do i do
Answer:	For AGMs, you can use the factory default, or "Gel Victron deep discharge", both of which are 14.4V charge, 13.8V float. Or, set it to your battery manufacturer's recommendation with a custom profile.
