Re: MPP HV2-5048 Earthing of output

Yep fair point
MEN = multiple Earth neutral

I would use one, though if the inverter doesn't like the neutral being connected to earth for some reason (some don't), then residual voltage detector it would have to be

Re: battery farm on site of old coal power stations

The station itself would likely be converted to a synchronous condenser too, so the infrastructure would need to be maintained into the future anyway

Re: MPP HV2-5048 Earthing of output

Fluke explains it better than I: https://www.fluke.com/en-au/learn/blog/digital-multimeters/dual-impedance-digital-multimeters I'm suggesting the 48vac difference measured is more a ghost voltage than anything to be concerned about. A cheap way to do it without a LoZ capable meter would be to put a ...

Re: MPP HV2-5048 Earthing of output

When testing potentials, did you use the meter in LOZ mode?

Otherwise you will be measuring with 1MOhm of meter resistance. 48v measured at 1MOhm suggests 4MOhm of isolation between the two

Re: 3-Phase Adapter

We call those suicide leads, as it's easy to make the other male end live and exposed at the same time.

If on different rcbo it will also trip both rcbos

Note, you can usually get away with pulling 14A from a 10A point, as they're usually protected by a 16A rcbo.

Re: Battery Self Discharge Rate

the issue with keeping the 12v battery charged tends to have been whilst the car is off, is making sure the big battery doesn't get run down to 0v.
not impossible, but certainly challenging.

The big battery won't go flat in that time, but the 12v one might.

Re: Motor voltage and RPM's

Motor voltage on a series would motor is a function of motor current and rpm. Increasing the battery voltage means the controller is now able to stay in motor current limit up to a higher rpm, leading to more power at high rpm. As a side note, your motor controller is more efficient at lower motor c...

Re: Chargers being turned off

on my zoe, pressing the plug release button on the car shuts down charging gracefully

given latching the plug is part of the type 2 standard, this should be common to all cars that take a type 2 plug
