Wrenches, Will
This is a hack trick but it can work as long as you don't have failed
cells, bring the static voltage up to 26 by adding just one battery, this
might be easier on the logistics issue. By doing this you will in the end
sacrifice the additional Battery but increasing the static voltage
AC coupled systems used to work like this but with solark and sort of with
outback they use the gen set input to the inverter, do the freq shift and
charge via a preset voltage. This seams to work well but if you connect a
genny it must be on the grid input via an ATS, alot more complicated the
any
Wrenches Ron
First l would think tech support already asked you this but.
I have seen this with outback,
What is the incoming voltage and freq, the Honda should be fine but the
other hard to say. Frequency is very important to be right otherwise the
inverter will sit and wait, voltage not as much.
First is it a prime mover or stand by? New or used?
You know that's really to small for a diesel and after you take the duty
