I wish to send the solar power from my grid tied roof panel to the batteries in my RV solar system. The roof panels produce approx 30V each. The roof panels are connected in series to make 300volts that feeds the grid tied inverter.
When the grid goes down I would like to use a transfer switch to send the roof power to my RV which holds presently 360AH of batteries.
I am guessing (but will calculate later), that depending on wire size, the 100 feet from rooftop to RV will provide sufficient voltage drop to safely add the rooftop panels to the RV panels.
The panels would need to go automatically from series to parallel wiring .
Can I apply those 30v panels into my RV system? Where would I make the connection?Can they simply be connected as are the RV panels at the roof top combiner box?
What is the maximum current my RV is likely to ask of these additional panels? That current draw will help me determine the needed wire size..
