Magnum inverter, Yamaha Generator
For anyone that is curious... A recent thread came up about about abnormal charging from a Magnum inverter, using a Yamaha generator as the AC input. My Magnum is a Magnasine MS2812, software versi...

Hi,
The 3012 Magnum hybrid has a limitation of 3000 watts (worst case would be 30 amps, assuming 100 volts, which I've never seen). In load support mode, it does not normally do voltage support. It is possible to "trick" the unit into doing voltage support by limiting the shore power input amperage. I did this for 3 weeks at a 30 amp campground in June. I had to "dial down" the input to as low as 12 amps. That meant drawing 64 amps @ 12 volts from the battery bank.
Load support on the Magnum does "combine" energy from shore power and inverter. Victron does the same.
On a fifty amp service in an RV, with a 15 amp shore power supply, the RV could use 45 amps in total, drawing the extra 30 amps @ 120 volts AC from the battery bank (x 10 of course to 300 amps DC)
I suspect there may be a microprocessor that controls whether load support is triggered or not.
happycamper002, I don't pretend to know how Magnum and Victron accomplish this "magic", but I can indeed tell you it does work. I'm pretty certain it is proprietary patented information, so asking them to explain the details won't get an answer.
Manuals are a special type of writing that try to be as clear as possible and assume a grade 7 education. Therefor they often do not have details. It is similar to the difference between an owners manual for a car, vs the shop service manual.
