What amp charger controller should i use for this kit and how many batteries should i have

Asked by Bob May 12, 2020

There are multiple factors to consider when sizing a charge controller, the main one being system voltage. The storage capacity of a battery bank is more important than the quantity of batteries. Multiply your total panel wattage by six (6) and then divide by your system voltage to get the suggested Amp-hour capacity of your battery bank. Reach out to support@grapesolar.com for assistance with sizing your system.
