That unit (Phocos PSW-H 5kw/120v) weighs around 110 lbs. I'm also considering it for my off-grid build, but I believe high frequency inverters generally weigh less and can double power on a surge for a couple seconds.

Can a frequency inverter cause a high voltage increase?

If a frequency inverter generates a steeper voltage increase, motor chokes must be installed between frequency inverter and motor. But since all drum motors from Interroll run in an oil bath, the risk of overheating or damage of the motor due to large voltage increase rates is extremely low.

What is the difference between a converter and an inverter?

Since different machines have different frequency and voltage requirements, a circuit known as a converter is used to convert AC current from the power grid to a DC current, and then an inverter is used to convert the DC current to an AC current with the frequency and voltage required by the machinery being driven.

Why is a high voltage measurement necessary for power efficiency measurement?

Therefore, the power efficiency measurement requires a high voltage measurement. Since WPT transfers power through coils, the transmit/receive part has a very low power factor. When the power factor is low, the phase error greatly affects the measured value, so power measurement with a low phase error is essential. Figure 5.

Why is inverter testing necessary?

Inverter testing is necessary in order to check for malfunctions of the inverter. This section introduces insulation resistance testing and voltage/current measurement, two tasks that are sometimes used in inverter testing.
