Q：Why does the controller stop charging from the solar panel?

A：Disconnect, measure the voltage of the battery, and see if the controller is fully charged. If it enters the floating state, the controller will stop charging the solar panel and charge the battery with a weak current to maintain the battery loss.

Q：Why did the load stop working after working for a while?

A：Use a multimeter to measure the battery voltage. If the voltage of the battery reaches the voltage value of the low voltage disconnection, the controller will disconnect the output of the load terminal to prevent the battery from excessively consuming power.

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:	Does this have battery overcharge protection? Or is it called something different
Answer:	Hello, The MPPT is designed to charge your batteries as a default voltage of 14.4V when in absorption mode (batteries are flat) then it reduces down to 13.8V when batteries are charged. These setting can be adjusted (the 24V setting are default at 28.8V and 27.6V respectively). Maximum output current is 30A. If you are worried about over charging due to different charging needs for your batteries these can be adjusted from the above settings. Hope that help.
Question:	What gauge wire should be used for the chassis ground
Answer:	Search google for "dc wire size chart" and make your own decision. I used 10.
Question:	Do i need a battery monitor with this? Is it really necessary? Im building a setup with 200 watts of panels, 2 100ah agm. I just want to do it right
Answer:	No. I just put one in with a 185W panel. The bluetooth app will show you battery load voltage.
Question:	Does the 100v 30A model have built in bluetooth as well? The picture doesnt show the phone next to it like the other models do
Answer:	All of the SmartSolar models have Bluetooth, the BlueSolar models do not.
Question:	If a conect my panels and my batteries to 24 v what will be the voltage that I¨ll recibe in the in load terminals
Answer:	Let say solar panel produce 36Vdc And battery voltage is 27Vdc The load terminal is about 27Vdc
Question:	What version of the 20amp model is being sold here from amazon? per the manufacturer website, renogy bt, is optimized for rover charge controllers f
Answer:	This is last year's model and currently sold out here the Renogy website and eBay. New models coming. Rich solar still has them at $89.00 for the 20amp..but offers no bt module
Question:	Can I disconnect the battery while the solar collector is still connected
Answer:	No, I dont think that's a good idea since they say connect batteries first the solor panels. If you was to shut ur system down, the go in reverse. Panels discount then battery.
Question:	Is anyone having problems with hf / vhf radio interference (rfi
Answer:	On MPPT and PMI controllers of different brands, RFI particularly in the VHF & UHF bands can be extreme. The solar panels do act as large antennas transmitting the interference. Some fairly simple decoupling circuitry can help. Right at the PV input, i've used a large forward diode into a large, CPU-grade electrolytic along with common-mode chokes on wiring before the diode. On the controller outputs, a "Corcom" type pi-filter helps a lot, but components in series with the output must accept full output current without much voltage drop. This can get rid of about 99% of RFI without too much problem. I do use solar and wind turbines for power at my off-grid property and run amateur radio equipment from 70 cm to 160 meter bands.

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.
Question:	Does this unit alternate voltage based on battery temperature
Answer:	No

User questions & answers

Question:	Can Tracer4215BN work with lithium battery
Answer:	Dear friend, The RS485-150U link: https://www.amazon.com/dp/B00YCSLQTA
Question:	Is the RS485 programing cable included
Answer:	The voltage of the solar panel is only 12V? If you are using a 12V system, the battery pack voltage should be 12V, and the solar panel voltage should be greater than 14V to charge the battery. The 30A controller can handle up to: 390W/12V battery, 790W/ 24V battery. You should choose to use a 24V system, that is, the battery pack voltage is connected in series to 24V. If you want to use a 12V system, please purchase a 40A controller. The 40A controller can handle up to: 520W/12V battery, 1040W/ 24V battery. https://www.amazon.com//dp/B07T2ZB98P https://www.amazon.com/dp/B077HQPV1Y
Question:	Is 800 watts of 12 volt solar input too much or will it clip the power input
Answer:	It is recommended that you use a 40A MPPT controller, 24V battery bank. Connect three solar panels in series and then connect the two groups in parallel. If you have 6*12V battery, it is recommended to divide it into 2 series in series, and then 3 groups in parallel to form 24V. Under the 24V system, the 40A controller can handle solar panels up to 1040W. (The total VOC of the solar panel should not exceed 150V (138V at 25℃ temperature)) Warm Tips: 1. Always connect the battery before connect the solar panel, disconnect in reverse order. 2. Make sure your battery has enough voltage for the controller to recognize the battery voltage 3.DO NOT connect any inverters, generator or battery charger into the charge controller. If an inverter is to be connected to the system, connect the inverter directly to the battery. 4. A fuse which current is 1.25 to 2 times the rated current of the controller, must be installed on the battery side with a distance from the battery not greater than 150 mm. 5. The controller is negative ground, any device of the system, even the communication device, can only be negative grounded or not grounded.
Question:	Which model for 24v (six 170w 12v pv in series/parallel) 1020 watt pv array, max open circuit voltage 135v, charging six 12v sla in series/parallel
Answer:	No, this is an entirely different device that serves an entirely different function than a BatteryProtect. The BatteryProtect serves as a low-voltage disconnect for small loads; this is a solar charge controller. There is zero overlap between the functionality of the two devices.

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
