[RE-wrenches] two VFX3524's and a Franklin 3hp sub pump

Hello offgrid Wrenches,

I just inherited an off grid system with one VFX3524 inverter running the
home loads, and a 17kW Guardian Generac they use for charging (through an
X-240 back into the inverter) & to run their Franklin 3hp 240 VAC well pump,
S. F. max amp 17.0 ( rated on its controller)

This is a really convoluted system as they have another 120/240 VAC
Transformer to have the inverter talk to the 240 volt signal the gen set
needs to see. Yikes.

So I am proposing to add a second inverter if it can run the well pump and
eliminate the extra transformer. This will also reduce gen set run time in
half while battery charging, a big plus with the nice 24V Hawker battery
bank, 1020 AH at the 6 hour rate.

There aren't any other unusual large AC loads in the home, just the fridge,
washer, computer, and such. LPG for cooking, water heating, clothes dryer. 

Thanks in advance for all ideas here!

 

Sincerely,

Chris Worcester
