| Inverter Generator module "balance" trim pot function |
| (1/1) |
| Dehv:
Unit has mini pots labelled Voltage, Current, overload and balance. Wtf is balance? Maybe ramp from eco mode? |
| NiHaoMike:
My guess is DC balance. |

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.)" |
