  • Charge controller question

    Totally Random Question of the day ::

    Is it correct to assume that charge controllers would be considered an inductive load with respect to the panels? (Both mppt and pwm?)

    The reason I'm asking is because I'd like to put a DC-rated mechanical relay in between my panels and charge controller. However, I know that inductive loads are really hard on the contacts of switches and relays.

    To that end, I was wondering if putting a properly sized flyback diode across the pv input terminals on the charge controller would reduce/eliminate the problems caused by inductive loads, and also allow me to use a general purpose relay instead of one specialized for inductive loads?

    I'm thinking basically the "diode type" example from www.ia.omron.com/support/faq/answer/36/faq02804
