This is a basic question, but I couldn't find an answer after searching a bit:
When I"ve got my inverter connected to the 12V batteries, will it "high voltage disconnect" if I'm also charging with a PWM controller being fed by 20V panels?
And, when charging with a PWM controller, can I use "nominal" 12V pumps, etc connected to my battery terminals?
Background: As I understand it, if a PWM controller is fed by, say, a panel producing 20V and 5 amps, the controller will
charge the battery at 20V and will modulate (rapidly cycle) the input charge on and off (from zero to 20V) to provide the correct average voltage and the right charge rate. If my inverter "sees" this 20V-Ov-20V-0V etc, it would seem logical that it could drop offline and generate a high voltage error. Likewise, if I've got a pump, fan, etc that is "expecting" to see continuous 12-14VDC, will it get that from the "12V" battery or will it get the "flickering" 20V from the PWM solar charge controller?
Thanks.
