I mounted 3 195 watt Kyocera panels, these put out about Voc 68.1, 6.8 amps ea.
I was concerned about the combined output with a 30amp Kid controller.
Spoke to their engineers, said the Kid has a built in over protect, said that with the oversized array I will get a bigger window of solar gain (number of hours per day).
At times mid day I see the lits blinking overcharge, but for instance it's 7:20 AM now I'm getting 20-25 watts of charge, peak I saw so far was about 420 W.
Since the Kid is the latest & greatest controller by Mid Nite it really works great, using 4 x 6V trojan T-105's.
Mounted the panels with standard L brackets, using the white roof sealant, drove 2400 miles they are still there
connected all with #10 wire, into two combiner strips one + one -, the positive has a circuit breaker before the Kid,
I also added a battery temp sensor.
I have a Kisae 2000 watt inverter no charger or built in transfer switch $320.
A seperate 20amp transfer switch ($60) from the main distribution panel to new sub panel. I left the 2 AC's & electric HW in the main panels for use only when plugged in or genny.
I rand a new wire for the 55amp converter charger off the existed transfer switch so it's only working on shore genny.
The solar charges the batteries way better than that charger.
The Kid was set to 15.5 volts equalize charge, this is a great feature to keep the battery bank in full even charge, it's not automatic you do it when you thin you should maybe once a month.
Lastly, I added a Magnum AGS.
So I think I can go off grid for a while.
ball park cost panels charge controller misc about $1,000.
