V2L discharge specs, 60Hz output on Australian MG MG4 EV

[domwild]

I couldn't find anything about standards that govern V2L output specifications for the MG MG4 in Australia. To me, the MG is a mobile inverter which can deliver AC power to loads and wouldn't be any different to a standalone inverter hooked up to a battery.

I recently got a V2L adapter and one of the first things I did was plug in a power meter that can measure voltage, current, power, PF, frequency.

I was a bit surprised at the output readings.

1. No load voltage is 215Vac (which is a bit low for Australian standards). Minimum is 218V up to 252V (240V +5%/-10%)
2. Frequency is 60Hz, which is more alarming because Australian grid frequency is 50 Hz.

Some appliances will malfunction or fail at 60Hz.

Just wondering if anyone else has picked up on this? I will be emailing MG for their comments on this.

The 215VAC is not surprising as I read it is the Chinese standard of 220VAC, but the 60Hz is perhaps a worry for computers??

to my knowledge, with computers, mains goes straight into the power supply, and converted to DC.
My transformer theory is ancient, but there's something about having too much iron in the core if the frequency is high. Maybe heats the transformer up, and runs less efficiently.
But I doubt it would be a major concern on a short term basis.
I think motors would be a bigger worry, both for voltage and frequency. I'd be monitoring them for heat build up.

It's been 15 years for me but I remember transformers having 10% more capacity on 60hz than 50hz

Frequency is normally a close tolerance
Voltage can vary

There's little these days that'll be effected by frequency

Switch mode PSU's are generally 0-100hz 70-260v input, that way mass produced items can be used anywhere which is the most common now

Transformers are more of an issue with ones designed for 60hz being overloaded on 50hz, also they're voltage dependant

Motors obviously go a different speed

Is the v2l ok with inductive loads anyway?
