Is 30 volts from the solar panel too much voltage for sunforce 30 amp charge controller?

I use the sunforce charger on a 12 volt system. It soundds like you have a 24 volt system.
444845
Yes ours is a 20 volt max. It should say on your instructions your max voltage
444846
Yes I believe so even though I don't have a manual handy. This charge controller is for 12 volt panels which usually run around 18 volts.
444847
Yes, 30 Volts is Over Voltage for sunforce to Handle it, Most of the solar panel run 18 volts Average, 30 Volts is too much to regulate, it may fry the Regulator.

You will need to use the formula that equates volts into amps to answer that question. Normally these controllers if set to 12 volt, usually can only handle a little more than 18.50 volts, just the gage on your car dash shows 18.50 volts as a maximum charge for such 12 volt systems. I am of the opinion 30 volts are too much for a 12 volt system. You should speak to a professional electrician for positive affirmation of voltage containment of 12 volt systems.

I have two 275 watt panels hooked to mine. I believe I have room to add another. It is a 30 amp charge controller. B

Of course friend, the panel is high efficiency, full sun generates 22 volts, you need a charge controller 12 Volt so you do not overload the system, it will keep you charged and when the battery is charged, disconnect, which prevents damage to your batteries!

If you have 500 watts of solar collecting capacity my understanding is that it would exceed the capacity of this controller. I recommend getting a 40amp MPPT controller. I got this controller for testing purposes but even my two panels rated at max 140watts each would exceed the capacity of this charge controller in full sun.

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.

Yes, it can. You may use any array voltage up to 150 volts, but be aware that solar panel voltages rise dramatically as temperatures fall. Check the temp. correction factor of the panels that you want to use. Basically don't go over a 90 volt series stack of panels to provide a buffer for when the panels are unloaded and to account for that surprise freezing morning. Over voltage is the surest killer of charge controllers, also be aware that the unit is rated 30 amps output to the battery, not 30 amps in from the panels. David Wardle

Yes. You'll be fine. Max amps are 20 for this controller. With optimal lighting your panels may never even actually reach 3x 5.57 amps. Also, since this controller will charge 24 volts, you can actually run twice the panels at double voltage and still keep amps under 20. Read the manual!

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.

Frank, i have a Renogy catalog on front of me and don't see a 350 panel. This must be something new. And by 30amp charge controller I assume a PWM charge controller. Your panel can be 12 or 24v not both, unless this is something really new. You might try one of the solar forums or email Renogy support. Don't call tech support because i tried. Don't. Ok? Try Northern Arizona wind&sun or midnite solar forums. Also midnite solar has videos on youtube about everything. You should be able to charge a 12v battery with a 12v panel and charge controller-period. Unless the battery is no good. Put a voltmeter at the output of panel then the output of charge controller. Good luck.

31.666 amps is where you are with your 4 panels. I agree with AT... You need a larger charge controller or research using multiple controllers.

Open voltage is not the issue. Make sure it is a 12 volt panel for a 12 volt controller. The important thing is the amps the panel puts out, the controller needs to have a higher amp rating than panel output amp rate.

Zach, go to the website: Remember to calculate the maximum voltage you will receive. For example, I use a 24 volt system for five solar panels of 270 watts each. When the sun shines at high noon, I get about 35v going to the batteries. So I figure my watts limitation for the C60 Charge controller is 2100, but I am coming in at 1350 watts for five panels.

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.

JD - Kindly edit your response, it is .3 of an Amp, not 2.4. Also- I would LOVE to know what kind of a controller you use with the solar panels and batteries.

Jaco, I have used that same breaker on my RV solar panel array. I have not had any problems with it. It is well build and it is resettable should it trip. Your load I am assuming is connected directly of the batteries. You did not state how many batteries you have. Should the load be greater then 50 Amps the breaker will trip. As you have stated that your controller output is 30 Amps you should be fine.

My panel is 50W, and this controller could handle more. It would make sense to me to wire them in parallel to keep the voltage around 12-14V and double the wattage.

The plug-in charger only puts out 2 amps. If your solar panel USB port has similar output there should not be a problem.
