Especially in rural areas - they run a 480 VAC supply with a common neutral.
I really doubt you will need more than 7 kW though, and with a solar-sourced EVSE it's likely to be more like 2 kW most of the time.

Andy - yes there's a missing connection in the car's wiring between the charge port and the on board charger. I recall Gelco in SA was providing replacement kits.

The Zappi will optimise for the solar output on one or three phase, but not two (it will optimise half the array, I presume). But 7 kW is heaps. As for the 32 A travel option, this is a sound approach, and many EVSEs like Tesla destination chargers are installed on a 32 A socket for added redundancy...

Cleared cache? We did have 'remember me' issues earlier this month.

I just emailed you a copy of the standard, AS5139:2019 which your battery will need to comply with. Not all inverters need an input from the bMS, particularly if they are told to run on a lead-acid profile where the absorption voltage is the same as the float voltage. I understand Victron does this.

Mike at Goodwe read the Western Power document, and he's confident it would be OK for an export of 5 kW provided the loads at the same time were on the same phase. Which is interesting, because I'm not sure which loads I should put on which phase...

I don't know if it matters or not, but at least with a battery, you'd be sending a large chunk of the energy to a battery before shunting it out onto the grid. Even better when you have an east-west array which will probably peak at about 4 or 5 kW anyway, well after the panels have warmed up and lo...

Heard back from Goodwe: Hi Chris, Yes. Just purchase a three phases meter named as goodwe GM3000. Then you can use this ES on a three phases house. So that's good. I don't care for the payment of 7 c/kWh, but I don't want to have my hardware limited, especially if I find I need to charge an electric...

Dunno. It's in Graeme's workshop.

So potentially twice the range for the same money, and no warranty or surety that it will last another 10 years. But hopefully it will.

Yeah we're making this a formal application with WP. I did call WP and *eventually* they told me that the 2.5 kW phase imbalance was a hard rule. This is fine, but I now have two concerns - one, can the GW5048D-ES inverter be programmed to never export more than 2.5 kW? And two, can a 3-phase EZ-Met...

Cost will be about $13,000 in battery cells, and maybe $500 in labour.

This diagram is from the GW5048D-ES manual - certainly it only works on single phase. Particularly since the S-BP manual lists the option of a three-phase EZ-Meter...

Presumably the inverter can be told to never export at a rate greater than 2.5 kW then? Considering what will be on at the same time, the EV can be charged at 10 A or 32 A, the dishwasher (10 A) can be run when everything else is off, and the shed (32 A) is likely to never be on when the house loads...

OK so I am settled on the GW5048D-ES inverter and a split east-west solar array (one on each MPPT input). The next quandary is the phases. Do I leave the three phase wiring as is and hook the inverter up to one of the phases, but use a 3-phase EZ-meter for pushing out what I use? Should I pay for a ...

No, not right now. But they can be brought into the country within a month. Will have to get a price, but if 5 iMiEVs are in the queue that's about 450 cells (including spares).

South Australian iMiEV owners might want to make a train holiday of it - come over to Perth for a couple of weeks and on a weekend we can do the swap. Once our quarantine restrictions are lifted, of course.

Based on the way those buslinks fit, the answer is yes, they do line up :) The plastic basket needed to be ground back in a few points so the cell sat snugly at the base. The plastic basket also has dividers which help keep the cells away from each other, but a little bit of EPA foam between them ca...

Just letting all you iMiEV keeners know that Graeme bought some of the 93 Ah cells for an iMiEV upgrade and they seem to fit OK. Took a bit of jury-rigging to have them fit into the cradles, but once the BMS tabs are added it looks quite viable. 93 Ah in iMiEV cradle.jpg 4s 93 Ah in iMiEV cradle.jpg...

Trying to get in touch with the council, but Gemtek are organising the DQA and getting it ready for Western Power to do their thing.

This seems as good a place as any to share:

From page 130 the good news starts

I reckon it has to do with settings, but by and large these 'upper-tier'* hybrid inverters are effectively playing an accounting game with your meter. They ramp up the AC output voltage until it matches the load being seen at the meter box, so export is just whatever is left over. I'm pretty confide...

I don't have any inverter on the house yet. The shed system is unrelated as it's too difficult to pair with the house. Since I only have real estate for one piece of power conversion equipment, it's going to have to be a DC coupled unit with two MPPTs. The Goodwe 5048D-ES is the best contender, and ...

wow that's crap - it would be a little heater - imagine summer that goodwe dc-dc unit keeps looking better and better I'm not sure what to do now. The GW5048D-ES is a single phase, 5 kW, 48 volt, DC coupled hybrid inverter. But it's limited to 6.6 kW of PV (I have about 7.5 kW on the roof now). Now...

Hmmm.
This from a Youtuber with one of these inverters. That is a huge amount of extra energy required per day just to keep it running.
