Re: How to tell a kilowatt hour from a kelvin week henry

How good would a speedo reading m/s be? "Do you know how fast you were going sir?" "Well under 16!"

Re: 3 phase supply but no 415v connections

It depends on the setting, but you can choose zero export, or at the very least, maximise self consumption. It would take solar energy and meet immediate loads, then with whatever spare power is left it will charge the battery. When the battery is full, it will divert solar to the grid. If will do t...

Re: 3 phase supply but no 415v connections

Terry - that was the inverter I was quite seriously considering for my home. As long as it can be installed inside and/or under cover it looks OK. AS4777 approved, but might take some convincing of the utility that it's OK to install.

Re: How to tell a kilowatt hour from a kelvin week henry

In the days before the Hornsdale reserve was conceived, all the talk was about the battery power. But there was virtually no mention of the battery's capacity. It mean the inverters were rated to deliver 100 MW of power, but for how long? It could have been a marketing thing - 100 MW is a decent rat...

Re: Tesla PW2

It's an AC coupled system, so it comes with an inverter built in. Easiest option for retrofits to grid-tied solar.

Re: 3 phase supply but no 415v connections

The vast majority of three phase off-grid places use three separate inverters, one for each phase, and a data link for synchronisation between all three. The link between them usually comes standard, and would be totally worth doing given the low additional cost. That said, if they have no three pha...

Re: Prelude conversion project - some questions

Hindsight is a wonderful thing - If I'd thought about it, I might have realised that the AC input cables were going to be quite difficult to terminate with so little clearance between the wall and the PCB. Still, they're installed and the radius isn't too tight. One more connector to install and we ...

Re: Prelude conversion project - some questions

I put a connector on the thermistor bundle wiring and plugged the Arduino in. A friend helped with some code (Quick Median library) which takes 5 samples and chooses the median value for the result. It means a far less spikey sampling (so I'm told). The readings from each thermistor varied by no mor...

Re: HELP PLEASE I think I killed my cells

1.6 V is not good, but if that's the lowest voltage, then I think you might be fine. Charge them at 10 amps - AC or DC that's not much current.

Re: 3 phase outlet, what is suitable for EV charging?

Not sure about the regs around running multiple 3-phase 10 A outlets on a single 16 A 3-pole breaker but the best you can manage is about 7 kW, assuming the vehicle was being charged from all three phases. Otherwise upgrade the wiring to 6 mm2 cable, install some 32 A 3-pole breakers and get the ful...

Re: Prelude conversion project - some questions

I popped the top off the 6.6 kW TC charger, and yep, it's potted like crazy in there, so no repairs will be happening here I suspect. However I could bolt the DC/DC converter to the lid with ease:

Re: Model 3 Pack Size

Pretty sure the pack sizes were ~52 kWh and ~75 kWh.
The long range car has 4416 cells as 96s46p. The cells are about 4.6 Ah each, so that checks out.
The 'standard' range (nobody would ever say short) is 96s31p, giving about 52 kWh.
