Hello,
Another newbie question. So, my DC monitor reads 35v open circuit at the Mppt terminal when amperage is zero, but as soon as it starts to 'pull', amperage starts to rise, the voltage then drops to as low as 20ish.
is this a normal behavior or do i need to upgrade my cable? i am currently using awg 10 30ft or so since it's a small less than 20am at most. i do have about 3-4 mc4 connections and a couple of xt90 connecting different sections, not sure if it affects anything.
thanks
