Re: adding a second inverter to the same solar array

Why not replace the water heater element with a smaller wattage one. I recently reduced ours from a 4.8Kw to a 1.8Kw, to better suit the solar system. The longer heating time doesnt much matter for me.

Re: Charging your non-Tesla EV from a Tesla charger

Perhaps with Tesla now matching Evie's prices, they can afford to make some concessions to owners of other brands especially as their own network is not so much of a sales differentiator any more. I suspect that everywhere but North America, Tesla is intending to switch to standard CCS2 anyway. The...

Re: OpenEVSE - Australian importer / vendor?

I bought mine from OpenEnergyMonitor in the UK. https://shop.openenergymonitor.com/evse/.
Dont know about certification.

Re: Chargers being turned off

By P1901, do you mean the ethernet over power lines protocol, per this Wikipedia article ? That doesn't seem to be relevant to this discussion. Yeah, it does seem strange when you call it ethernet over powerlines, but if you expand your thinking to data transmission over powerlines it starts to mak...

Re: Chargers being turned off

Huh. I find a fixed resistor in my type 2 to type 1 adapter cable (I have a type 1 Leaf). I wonder if any sudden change in the resistance will trigger a termination of charge. I dont think the 'change' is the trigger, it's the resultant voltage levels that are measured. ref: https://en.wikipedia.or...

Re: Chargers being turned off

CCA2 uses a similar signalling protocol to type 1 chargers. If you mean CCS2, CCS stands for Combined Charging System (i.e. DC as well as AC). Type 2 AC ports use a similar signalling system yes, but the proximity pin has a different use. You're right, I find the term "type 2" to be a very indistin...

Re: Chargers being turned off

CCA2 uses a similar signalling protocol to type 1 chargers. A simple NC (normally closed) switch across a 330ohm resistor in series with the pilot signal from the vehicle will cause the vehicle charger to shut down and the security latch to disable so that the plug can be removed safely when the swi...
