I have 4.... 85 watt solar pannels connected to 6... 6volt batters connected to make 12 volts system... my controller keeps b lowing fuses....

One 85 watt panel Should deliver around 7 amps at 12 volts in full sun. If you have all 4 panels connected through a single (7 amp) controller, it is way overloaded. Sounds like you might need 3 more controllers or simply a bigger controller unit.

I really don't know. Is the controller putting out the proper voltage? Could be a defective controller. Are all batteries properly connected? Are you using the correct fuses? Best of luck!

Either your voltmeter is defective or the solar panels are. Their output should be close to each other assuming they're getting the same amount of sun. 5 watts @ 12 volts should be about 0.4 amps.........voltage output under ideal, sunny, conditions should be in the 10 -14 volt range depending on temperature and amount of sunshine. I assume the wire lengths are the same for each, otherwise the longer the length the lower the output.

If you plan to add more panels, you will need to use a bigger charge controller or stack another charge contorller. This charge controller only only fit 240W and 480W for 12volts and 24volts system.

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 have a 1600 watt inverter connected, also with an inline fuse. It all works fine, my only concern is the cables get quite warm, but it has been connected for about a year now just fine. Makesure you use an inline fuse with proper watt fuse.

I am charging two batteries(lawn mower size) from the panel through the regulator I am adding a transformer to smooth the circuit,,, it ends at a 1000watt inverter, everything seems good, the panel generates electricity even on cloudy days... MPP

I think you need to check your controller specs, but I know some controllers may just shut off to prevent damage. Also note these panels are higher voltage which may not be compatible with your controller. I bought a charge controller that won't work with these because the voltage may go up to 45V on these panels. Now I run two of these with the Morningstar MPPT 45A charge controller. Morningstar has a calculator on their site that will confirm whether a planned setup will work with their charge controllers or not. I am planning on adding one more panel to my setup. The 45A MPPT charge controller can handle 3 of these panels. Good luck!

yes you can u can. google a connector that will hook 4 together.4 would only be 60 watts so 1 controller should handle it.Although u should be at least using 2 deep cycle batteries so u can pull a load up to 7 amps.

I have 14 115ah deep cycle batteries powering a small off grid house. On a sunny day the solar system will fully charge the batteries. I will soon be adding a 400 watt wind turbine to help on cloudy days.

The charge control can handle up to 7A. Your 30 watt panel puts out ~1.68A at high noon. You should be fine with one charge controller charging two or more batteries and it would require more charge time. Just make sure you hook up your batteries correctly. Personally and for convenience I would much prefer to get two charge controller with two solar panels for the two batteries so that I could avoid having to move and or reconnect the batteries. A larger solar panel can would benefit you quite a bit if you need to drawn power from the battery each night. Hope you are using deep cycle batteries. The charge control can handle up to 7A.

You need to connect the panel with solar wire connectors like the MC4. You can connect to several batteries as long as they are connected with the correct voltage ie 12 or 24 volts depending on which way you go with the charge controller. Connecting 12v batteries in parallel will give you 12v. Go in series and you get 24v.

If you are using 4 panels with this kit it only uses a 20 amp controller. You must be using a 24v battery bank to use up to 400 watts. Can you explain your situation a little more? We are a bit confused with what setup you have. Thank you. AW

I agree with most all said here before. Get 2 12v batteries in series = 24v, or 4 6v and hook up in series but controller is best way to go to match your solar panel. Most quality solar panels will charge 12v and 24v. Get a volt meter and check it out as you go. A fuse is a must. Good luck

It's rated at 20amp. Each of these panels are rated at 5.7amps. It should handle 2 panels, perhaps 3. I would think 4 panels would begin to limit the amperage. You can also use multiple charge controllers rather than trying to attach a larger array of panels to a single controller.

There needs to be an in line 20 amp fuse between the battery and the controller. I put mine near the battery.

you are running on a 12 volt system I use 15 amp fuses, but I check my draw and output accordingly and don't push more than I need or run more circuits and have switches, like 6 flood lights and a separate circuit for appliances/tools, depends on your 12 volt battery, a trolling motor steady draw or a faster high output for tools with a short draw.

It needs a voltage regulator to keep from overcharging the powerpack. I have the cheap 10 amp ($15) controller. Output from this panel can exceed 20 volts in strong sunlight.
