Hi all
As always I am impressed by Hugh's knowledge, but I
still disagree. In my most recient example DC
charging is the only solution. I have a very large
surge load, the AC generator can not handle, yet the
inverters can. So I have 5 outback vfx inverters,
supplying the load, and I use a MX to charge the
batteries from the generator.
I step down the genertor to 60 volts with a X240
transformer, and rectify and then to the MX which
charges the battery.
Thanks
Daryl
