Hi All,
Have 8 x 300w mono panels running our small house totally off grid. More than enough power for what we have been using. I am keen to work out what sort of spare capacity we have but. If I check the charge controller around midday to see how much its putting out its normally already charged the batteries and in trickle charge mode.
what I was thinking is finding a way to dump the excess power to say a water heater and measure how much power goes into that circuit. That would tell me how much excess power we have.
Looking at building a bigger house at some point that will no doubt need more power so would be nice to work out how much spare head room we have now.
any one got any other ideas ?
cheers
