Magnum Hybrid Inverters

The boost circuit is basically a copy of the Trace 2500, 4024 technology of the early nineties. When the LOAD side of the AC is online, when powered by a pass through AC source, it detects the sag of voltage which has a specific threshold It stops charging maintaining the batteries and goes into inverter only mode. The inverter "synchs" with the incoming AC power and raises AC output voltage to a specified level. This "boost" has to have a default timer built in to avoid constantly draining a battery bank because of an continuously insufficient AC power supply source. The "boost" could be enabled in as little as 30 ms or as much as 70 ms. We'll have to wait and see. A 15-second boost assist window should be plenty to allow motor start assist. With new style software maybe the boost assist could be repetitive a few times then default. Pure guesswork on my part.

I like the 60 amp transfer relay a lot more than the Trace 30-amp relay on the 2500 series machines.

But shorepower 50-amp is 240 volts divided in half with a neutral. You cannot "combine" them and remain plugged in unless you do some serious rewiring and use a transformer. It would take a four pole double throw 60 amp relay to allow passage of all the 50 amp shore power current through the RELAY. One half of which could go through the inverter. Don't forget neutral is involved.

Unless Magnum did some fancy MOSFET footwork, Pure sine wave inverters don't play nice with modified sine wave inverters.
