Inverter Generator module "balance" trim pot function

Unit has mini pots labelled Voltage, Current, overload and balance.

Wtf is balance? Maybe ramp from eco mode?

My guess is DC balance.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

Found this from Jon Watte on quora:
"The inverter has a measured efficiency curve. E g, at output power X (or output current X, which together with the average voltage, gives you power) it is measured to be Y efficient.

Thus, you can easily calculate the (average) power balance — DC voltage in x DC current in equals average AC voltage out x AC current out divided by efficiency in percent. (The rest of the power goes into heat.)

Typically, there is a “sweet spot” where it is most efficient, and typically this is close to the maximum rated continuous load, and efficiency falls off with lighter loads.

A cheap inverter for occasional use may be only 80% efficient at average load. A high-quality inverter for whole-house use might be 96% efficient, which sounds like only 16% better, but the cheap one actually generates 5 times as much heat as the quality one in this case. (20% heat versus 4% heat.)"
