Re: Prelude conversion project - some questions

Ah - might have a solution to the charger issue. I hadn't grounded the Charge Sense pin of the EVMS3 before attempting to change the charger settings. So that might explain that problem (hopefully). But the backfeed through fuse 12 remains a problem...

Re: Solar day parking with AC charging

Even with a 90km range i-MIEV the shopping centre carpark chargers seem more of a marketing gimmick than any actual use. You'd need to be really pushing your range to the limit going shopping for it to be a significant benefit to slow charge for an hour. Sure - but this isn't so much about EV owner...

Re: Solar day parking with AC charging

If workplaces and public carparks had charge points, even only 2 kW or so, that would soak up excess solar in the middle of the day which is demand that won't happen in the afternoon. The total generating capacity of the grid is unchanged, but the timing of its use is shifted back to when there's an...

The rear does sit about 25 mm lower than the front, so I think we'll need some stiffer springs to correct this.

Re: Prelude conversion project - some questions

Congratulations Chris. Well done. I was wondering why such a long precharge time. We do it in half a second in the MX-5. But I see you have no choice. It's built into the Greatland inverter. I could actually solder an additional resistor in parallel to speed it up, but I think we can afford the 4 s...

Re: Prelude conversion project - some questions

We tried putting resistors in series with the enable line, and it was an on or off situation, so I don't think I can adjust the charging current that way. Anyway, the set voltage is way too high, assuming we've not successfully changed it via the ZEVA. I can get a charge in from a 32 A socket but I'...

Well some good progress made this weekend - it's finally spun the wheels. reecho kindly offered the services of his open EVSE which allows you to charge a Type-2 car from a 15 A GPO, at least for testing. However a couple of issues have popped up making it a no-goer for the time being. First of all,...

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...

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...
