Re: melb-syd-melb (via canberra) in a Kona

Very nice. It must be great to have 64kWhrs under the hood and the option of 70kW charging.

Re: AVASS cells 2nd lot

Sorry, do not know anyone wanting to sell. However, I bought 8 cells (no spares) and fortunately they are going okay so far. I can get about 430AH from them in a 24V system at rated current 0.2C. One of the cells is definitely weaker than the others, but at the price the 30AH or so is no big deal. I...

Re: NSW Zoes please note

Hi Lou, great you have profited by such a huge amount.
Our governments are SO generous and SO encouraging are they not?
Several of us have missed out because of the incompetence of RMS so we'll be coming to you for a share of your new found wealth (just kidding)!

Re: Is anyone using an arc welder with an offgrid system

Hi Harold, I am very pleased they sent you the new module and that you were able to install it and it WORKS! That is good customer service and you should be able to make a spare power module that you probably will never need. I used 75mm2 wire and also a hydraulic crimping tool. I also used conducti...

Re: Earth leakage Zoe with Tesla DC charger

Hi Chris, Leakage currents all relate to the three phase AC input to the charger. DC is apparently measured there also but would most likely come from the traction battery or rectified AC. So it's a bit like having a very comprehensive RCD. Incidentally, in Europe they have specs for the curve of RC...

Earth leakage Zoe with Tesla DC charger

I did some tests on a Tesla DC today. It has two cables (left and right). The right EVSE always works with my Zoe. The left one only works about 20% of the time with a charging impossible or check charging post error. My theory is earth leakage is the problem. I got to test the right hand (working )...

Re: Heat pump hot water systems

Hi Richo, Peltiers are so inefficient. I built my own Solar HWS from evacuated tubes, using a standard (non solar) HWS tank in 2011. Total cost was <$2000. Did not bother with STCs. Performance over 8 years has been brilliant (in Sydney, suboptimal 70deg Azimuth, lots of huge trees). Totally exceede...

Re: Fascinating Spreadsheet

Hi Chris, Your problem was different from what this spreadsheet indicates. If Zoe cannot charge at the full amperage defined by the pilot signal (eg because of battery temperature), it just scales back but continues to charge, albeit more slowly. Also, when staring charging, it always starts slowly....

Fascinating Spreadsheet

Zoe folks (and possibly Chris Jones) might be interested in this spreadsheet which shows the relationship between battery temperature and maximum charging rate and SOC. You need to select the 40kWhr rather than 22kWhr sheet. Also, the spreadsheet covers Q90 with 43kW charging. Though this might affe...

Over a year ago, our Zoe lost signal a couple of times and I had to restart one of the onboard computers by pulling a fuse. This...

Re: New/Unused A123 AMP20 pouch cells x approx 120

I did contact them a couple of times and made offers which were not accepted on each occasion. I have since bought some cells from Suzi Auto and was lucky enough more recently to get 8 AVASS cells. So I am no longer in the market and the ex golf cart CALB cells from Suzi were cheaper by far in terms...

Re: Way to start and stop an inverter

Hello Harold, I have now used my inverter, which is almost the same as yours, quite a bit now. I have turned it on and off in all possible ways. When charging my EV from it, the BMS interrupts the battery connection to the inverter when any cell reaches 2.8V. I can start the inverter with load attac...

Re: My experiences with the Zoe

Hm. This might be an issue when they finally sell their demo vehicle! However I guess it would be covered by warranty.
It's a pity they did not take you more seriously and thoroughly investigate.

Re: NSW Zoes please note

RMS did not update the Web list of vehicles as of this morning, so I contacted them and they have now done the update (and fixed the "Renalt" spelling for Kangoo).

So, finally Zoe is on the official list.

I note the Tesla 3 is not there yet

Hi Harold, They would almost certainly be good. Probably exactly the same as in our inverters. However the French Tax man might charge you extra. Ones from Mouser, Digitech or Farnell would be totally genuine. I'll be back to France for just a month next year in Bretagne. My daughter and two grandso...

Re: Is anyone using an arc welder with an offgrid system

Hi Harold, I totally agree. With only 1 of 7 FETs dead (and open circuit) in half the bridge, you could probably (in theory) run it up to 6*6kW/7 or about 5kW. But I would not do that if I were you. I would have no hesitation in running a 100W fridge or even drills and lights. I can think of no reas...

Hi Harold, Glad it worked okay. You would have no trouble with a 100W fridge- though there will be a surge when it turns on but nothing problematic. It is excellent news the seller is replacing the power module. With a replacement FET the other one can probably be easily fixed. Regards, Dave PS- I k...

Re: Is anyone using an arc welder with an offgrid system

Hi Harold, Yes, it is very possible that now that FET is blown it will work on the other FETs. Get a multimeter and check that there is not low resistance between the Drain (centre) and Source (right) legs. There was probably sufficient energy to open circuit the FET. However, most of the FETs I blo...

Re: Is anyone using an arc welder with an offgrid system

Hi Harold, I think that is a good offer. When you finally start it again, see if you can borrow a regulated power supply with current limiting. Set for 24volts and 3amps then connect. If this is not possible, you could so what I did when I first ran mine. I put a couple of small 12V VRLA batteries i...

Q24 also looks like there might have the start of a crack in its gate lead. Certainly a crease in the metal.
