Hi, I filled it out, but there are a few questions where the context was missing. Range question as above - yeah I do 400 km a week. "Who makes the best chargers?" and you list several kinds of charger, not makes of charger. I chose 3-phase socket cause I like simple and cheap. Option 1 at the end? ...

On the matter of pronunciation, I recall discussing organic molecules with a lecturer way back in 1999. Benzoyl chloride, according to Max Gunter, was "benz-oh-isle" and not "benz-oil" as I preferred. Good thing us chemists use hieroglyphics by default.

We did have data, but it's not being shared any more. Plus, we have a situation where the chargers are being run down to the point of disuse. Recent data wouldn't actually be all that relevant any more. What we do know from Chargefox et al. is that most people do their rapid charging during daylight...

All sites have grid power, but the supply is weak. As in the HV transmission lines are also small. You could totally scale it back but I feel 60 kWh would be a practical minimum. Knowing you wouldn't see too many travellers in a week means you risk a bit of an overspend, but it also works the cells ...

I found this thread and thought it's as good a place as any to list my musings. We are trying to get DC fast chargers installed in the West Australian wheatbelt where distances are vast, towns are small, and power is weak. A charger might be $35k, but the cost of installation and connection to the g...

I just found an Alibaba supplier of these cells: https://www.alibaba.com/product-detail/Solar-Battery-Lifepo4-battery-400Ah-3_62003627098.html?spm=a2700.galleryofferlist.0.0.48b760c7dMXe93 Might be a good source for more spares. https://www.alibaba.com/product-detail/Solar-Battery-Lifepo4-220Ah-3-2...

Hey Andrew,
I should be able to ship the buslinks and PCB over to you by the end of this week. Looks like a great fit!
If you want to cut the current 30s2p boards down to 26s2p you can do so with a Dremel and a mini cut-off wheel. Shame the controller can't take more volts!

Called it at 17.2 kWh on the AC side.
If the two lowest cells had a bit more in them it might have pushed out to 18 kWh easy enough. Still, a useful amount of stored energy for a warm night.

Yes, yes of course.

Some preliminary testing before I start to assemble the battery enclosure. 20200503_113657.jpg I decided to use the 4 kW PIP inverter bga left with me as a means to provide a regular load. It also has a built in charger at about 1.8 kW when plugged into mains. I still don't have a BMS on the battery...

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 ...
