It works so far.
I hook my Kisae inverter up to my refrigerator, which I already know works turned it on and power started dropping, as usual.
I had already hooked my 240vac charger up to the Morningstar controller. After powering the fridge for a little while battery volts dropped to 12 even.
Figured this would be a great time to test my battery charger. It was already hooked up to grid external power all I had to do was flip the switch.
About 3 seconds later I herd a click that sounded like a fuse blowing. My 20 amp blade fuse blew. So I turned off the battery charger and plugged in a 25 amp fuse.

The 25 amp fuse did not blow. So I put my fluke325 on there and it was reading 26 amps going to the battery and inverter. The inverter was only drawing 11 amps at 14 volts.

So now I will upgrade to 10 gauge wire on my battery charger. And put on a 10 gauge 40 amp NAPA in line blade fuse holder. I will fuse the circuit at 30 amps to reduce nuance fusing.

I may also install a charge limiting resistor like I have seen used on NiCd batteries.
This battery charger need to be able to charge low batteries with out fusing.
