Wiring Diagram

The diagram above for the Renogy REGO System illustrates this dual con fi guration method for an 800W array. REGO System Series and Parallel Wiring Diagram Once you have determined the total wattage and wiring scheme for your system, use the optimum operating amperage of your solar array and multiply it by 1.25% to calculate a safe margin of error. Let’s say your 12V-600W solar array (wired in parallel using 3 x 200W panels) can produce up to 27A. 27A x 1.25%=34A, you’ll need a charge controller larger than 34A. But, you’ll also want to make sure that the charge controller can handle both the operating voltage (23V) as well as the total 600W coming in from your panels. Charge Controller Specs At fi rst glance, it appears that the Renogy Rover 40A MPPT will do the trick as its rated battery current is 40A and maximum PV input voltage up to 95VDC, but it can only support a maximum PV input (solar array) of up to 520W at 12V. So, the 40A
