User questions & answers

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:	How many 300 watt 37.5 volt panels can I use on the 60 amp controller with 12 volt batteries
Answer:	I purchased this system to act as a 'test bed' prior to buying my main dual-axis 2 panel system (Two 250W, 24V 8A panels). It's a monocrystilline 100w panel stated to output 5 amps, 12volts. I see consistent 13~14 volts at 4 amps, and have hit 5 amps on really good days (but 4A are more realistic). As a test item, I had it charging a 73AH Deep Cycle Gel battery from West Marine (the panel came with a 30A PWM charge controller). It worked fine and charged the battery in a matter of short hours ( I have both an amp meter and a volt meter connected to track its output). Previously, I was using two 45W amorphous panels (Harbor Freight) that took up to 4 days to do what this one panel can do in 4 hours. Buy with confidence.
Question:	I only see settings for float and equalize charging. Where can I change bulk charge settings
Answer:	I don't recommend you install it on the wall. Put the charging station on the horizontal surface to make it more convenient to use. YCCSKY
Question:	Can i connect this to a ac volt to dc volt wind turbine
Answer:	No, this is a controller charger,all it can do is charge the controller
Question:	What device do you recommend to controller it using wifi

Answer:	This inverter system and remote switch provided is a "manual only" simple push button on/off switch, with a power on light and a "fault" light on the remote switch plate. The power usage display is on the inverter. The remote switch uses a 150 volt rated 4 prong wire, with telephone style connectors on both ends (15 foot is provided). This unit is designed as a manual only push button on/off system but that being said, a power failure system could be wired using a series of relays to activate the on/off side of the switch (2 wires) but you would have to design the relay system yourself to make it work.
Question:	I just bought this unit and if I am using it with a 150 watt panel and a single 170 ah Lithium battery, do i need to set up a custom charging profile
Answer:	we have put email address [email protected] in the new batch . Sorry for missing email address. regards Gi andel
Question:	Can I connect a battery charger and generator without disconnecting the controller
Answer:	In my system the charge controller is between the Solar Panel and the batteries. The inverter is between the batteries and the point of use. That would mean the charge controller charges the battieries and the inverter drains them. They have no direct interaction except the storage batteries. I have no experience trying to connect the Solar Panels directly to the point of use without a battery bank between them.

Question:	Can you turn this unit on and off
Answer:	yes, it will work. contact us if you have any questions.our email is [email protected] PowMr Service Team
Question:	Can i use 24 volts system for this
Answer:	If you're speaking of the 10 amp charge controller, it should work but it will take a long time to charge the battery if it's used very often. It will charge it but the maximum current you have available is less than a quarter of an amp. You can double the current (amps) by putting panels in parallel, but your panels are 9 volts and would only put out the voltage required to charge the battery if they were in direct sunlight (straight on to the sun, not with the sun at an angle). And as KK said, you can get a smaller charge controller for less money. You can find complete systems designed exactly this purpose that are portable and self contained. I started out with a folding portable120 watt system with two 60 watt 12 volt panels, a built in 20 amp charge controller and a 100 AH 12 volt battery for a little over 200 dollars. (I recently added an extra battery that cost me $189 for the battery alone!) So yes, it will work, but I would suggest getting a standard 12 volt panel and not using the very tiny 2 watt 9 volt panels. They can be put to better use for another purpose. They're really too small to efficiently charge a 12 volt battery. It would probably be able to maintain a charge, if the battery is not used very often, but it wouldn't charge it very fast if it were drained down any through use. This controller and a 50 watt 12 volt panel would be good, supplying you with around 4 amps charging current (in full sun) instead of less than a quarter of an amp (again in full sun) you have available now. You will also have room to grow, adding extra panels and a larger battery later.

User questions & answers

Question:	I have a 370 watt solar panel. Will this charge controller be sufficient
Answer:	Check the manuals for details but I do believe it works with lithium. But do be careful altering the settings, if you mess up then it would cause a very hazardous fire.
Question:	Can i put 4 in series, w/ 48v battery? 4 panels x 37.44 v = 149.76 v 4 panels x 8.68 a = 34.68 a
Answer:	NO, it is for 12/24 volt systems.
Question:	I have 2 260w solar panels rated at 38.1voc. Im trying to set up a 12v battery bank that this will charge. Will the 150v/35A be too big for my system
Answer:	Mine came on time as it was in stock
Question:	Is the output voltage range adjustable? I have a 24v lead acid battery bank and want to keep a 27.5v charge. Is this possible
Answer:	I don't think this was intended to charge a lithium battery. It is used to charge Deep Cycle 12 V. or perhaps 24 V. batteries for RVs from a solar charger. For lithium battery recharge, I'm pretty sure you need a very different device!
