What size Charge Controller do I need for this panel?
264926
For one panel any controller that will handle 3 amperes or more. The max output is about 2.8 amperes per panel. More panels in parallel then add up the amperes

I went with a 10A. It leaves headroom even with a second panel in parallel as these panels only put out about 3A in direct sunlight.

This unit puts out 3.3 Amps at 22V at full sun (72.6W actual) I bought a 7A controller to work with this.

Is this the only panel in the circuit? If yes you could use as little as 10 amp charge controller.if you plan on adding I'd total the amps your panels produce....

For one panel I use a 7 amp in line charge controller.The Sun Force 7 amp controller, which is available on Amazon for $14.01, has worked well for me.It also contains a diode to prevent the battery from discharging at night.The max output of the panel is about 3 amps.

The charge controller is programmable to set upper and lower cutoff voltages for different battery types. I have not used these settings but am very pleased with the controller and panel.

I use a 20watt panel and a voltage regulator. If you have a battery,you will need a solar regulator.

I highly recommend using a charge controller with any solar panel to eliminate problems that you are speaking of. After I started using a charge controller I have not had any problems at all. Even on a 5 watt panel I would use a charge controller.

Contact manufacture of your panels on what the output of both panels would be relative to your Volt/Amp requirements. It has been many years since I used Ohm's law! Good luck! (my connectors are still in the bag, as I had the same question,I received no response when I made my inquiry)

It is best to use a solar regulator (or solar charge controller). 3Amp or greater charge controller for 1 x 45Watt panel. You can find lots of inexpensive ones on Amazon. However, if you are just using it for a quick boost charge, you can hook it up directly to the battery. But, if you connect directly, you must monitor it to make sure it doesn't overcharge (cook) the battery. And, never leave it hooked directly (without regulator/controller) to the battery at night, because the battery will discharge into the solar panel.

Hello,If you are charging 24v the controller can support 3 of these panels.In 24v the controller can support up to 800 watts.Please let us know if you have any further questions.Regards,Austin WaltiRenogy Technical Support Rep.

I my self would get a bigger charge controller at least 45 to 50 amps becouse you will like the dms solar pannels.

You should have at least a basic charge controller to avoid over-charging your battery and possibly damaging it. The panel has built-in diodes to prevent discharging your battery when there's no light on the panel.

I am using the panel connected directly to a large, deep-charge battery, and it works OK. You can go through a controller if you are worried about overcharging your battery.

You'll need a charge controller so the connection will be: panels>controller>batteries>inverter

You need a charge controller pretty much for any solar panel over 10 watts. I like the ones that have a digital voltage meter and built in float mode. Lots of choices for controllers in the $20 range Panel has held up well so far on my sailboat.

A controller is required for these panels as they pruduce 4.2 amps at peek output

I have 2x240 w panels in series (60v x 8 amps) connected to 50 ft of 10 gauge wires going to the charge controller. From the charge controller to my batteries (12v), I have 2 ft of 2 gauge stranded wires with a 50 amp fuse. The 2 gauge wires barely fit into the charge controller terminals. The idea is to minimize power loss from the long wire run between the panels and charge controller by connecting the panels in series to attain maximum voltage (not to exceed the charge controller specs) and minimum current. Between the battery and charge controller, I went with the shortest and thickest wires possible since its output can go up to 40 amps.

for these panels since they are 24v panels you would need an MPPT charge controller. You would also need an adapter kit to connect your panels to your charge controller an a tray cable to connect the controller to your battery bank. And since these are 24v panels you would need a 24v battery bank.

Yes, but you will need a charge controller with this panel. A charge controller is designed to protect the battery by managing the charge rate.

the owners manual that came with the Powerpack had directions on how to install the proper fitting ( same as the charger/converter end) on a standard 30W panel, I don't have mine anymore or I'd look it up for you, Sorry.
