Westinghouse i4500 Generator
I posted a few weeks ago about trying to run my AC with a Yamaha 2k genny and Magnum 3000W boost inverter. Sort summary - the Yamaha just wasn’t strong enough with surges to work. So now I’ve pur...

Bob213 - my Magnum inverter is feed from the shore umbilical and then feeds my whole RV through the panel. I tried starting with the inverter off, but no go there too. When the inverter is ‘off’ it passes through 60A per leg, but it still has the voltage integrity checks etc.
I’ve mess around some more and now am starting to think that I might have been too cute trying to limit the input current and have the boost take over. I’m thinking that it may be the input current limit was kicking in and not letting the genny do it’s job. And for some reason the boost function isn’t just additive to what’s coming in but instead might somehow be kicking out the source for another integrity check and then getting in a loop.
I’ve now upped the input limit to 27A (altitude based output of the genny) and it’s been running fine for quite a while. Given I’m getting cooling I’m done messing around tonight. Tomorrow I’ll try restarting with these settings, maybe even take input limit up to 33A (generator boost capability) or higher and let genny take itself out of the loop instead of Magnum dumping it out.
I’m hopeful that that will resolve my issue. Still don’t understand why Magnum boost doesn’t just add to incoming without forcing integrity check if that’s what it’s doing. I’ll mess around some more tomorrow and maybe call Magnum support on Monday.
Thanks for letting me think this through on-line…and for any suggestions still to come
