Magnum Inverter/Charger Design Tradeoffs
FYI The Magnum Inverter/Chargers are very good but cost tradeoffs in the design were made. I discovered the following on my ME2012 (2KW inverter and 100A charger) and these cost tradeoffs were made ac...

2. The DC amp display is estimated on the AC input current and not on the actual DC current. For example my unit will display 100A when in fact it is charging at 80A.
3. A battery voltage sense for the charger capability is not possible.
Magnum wants you to buy their add-on battery monitor module so they can squeeze some more $$$ out of you. The BMK gives you a 500A shunt to measure DC current in/out of the battery down to the milliamp level. It also enables a bunch of other features.
Not sure I understand point #3 ... are you talking about state of charge estimation using the battery voltage? I think there are battery voltage based "rules" you can program into the charger if you are using the advanced remote, another up-sell from Magnum
