Question 1

What other equipment will I need to add more solar panels and what is the max wattage for this charge controller?

Accepted Answer

this is a great start solar package.  this is what i had.  Rover 40Amp will allow approx. 6-7 100 watt solar panel.  Each 100 watt solar panel at max will produce around 5 amps.  So 6x5=30 amps; 7x5=35 amps, so these numbers of solar panels will NOT exceed or damage the Rover 40A (amp) MPPT solar charger.  if you plan on expanding your solar array, buy more brackets and wiring (especially if you are doing parallel wiring) and more quality batteries (rec AGM or Lithium ion); buy Will Prose IV book on amazon!  great resource.

Question 2

Can this power an ac and refrigerator on a class a motorhome?

Accepted Answer

It would depend on your battery bank and inverter. Not so much the solar kit. How large of a ac and fridge and how often will they be ran? For me I run my fridge on propane. I try not to run the ac to much. For some basic info, I have 4 12v 100 ah agm in parallel. This gives me 800 ah. I run a couple of essentials 24/7. They do not exceed 1.8 amps. Ever. By batteries charge Fully off this system almost daily. They battery bank never never drops below 12.4 volts.

I can run a 1500 watt fridge or ac about 5.5 hours. I’d you know the wattage of your appliances apply the following:

Usage Hours = AH/(wattage/0.85/volts)

Question 3

Is it ok to hook up the solar panels to my batteries and charge them at the same my time my rv is charging them?

Accepted Answer

Yes, the Renogy 400 Watt Kit can charge the batteries by the included Renogy Charge Controller and at the same time the RV can charge the batteries with the Renogy DC to DC charge controller when there is no sun light on the panels.

Question 4

How many 100AH batteries can i connect to this system?

Accepted Answer

It’s not how many.  What are you trying to do with the system.  I have 500 watts sending in a charge to a 200 ah lithium battery.  I use a 2000 watt inverter.  Can do all I want except run AC on it.  Solar will keep mine charge to a 100 % all the time.  Hope this helps
