In the garage I have an older 100amp PM3 on a battery at 13.5v with a 400w MSW inverter also on the battery supplying the stick house internet modem as a UPS.
Meter on hz setting says 59.75 on the inverter and 00.00 on the PM3 DC output terminals. In the MH, the 75amper at 13.5 has 00.00 hz on the DC terminals. Readings jumping around everywhere in the PSW inverter GFCI outlet. Get 59.94 in the MH outlets from the stick house shore power.
Can't test the 55 amper in the TC that has the LED for now, as the TC is away for dog training.
