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...

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

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...

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

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

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

Hi Richo, Yes, I would say you are correct. That would explain pretty much everything. First time run of the inverter, shipped from China to France, bad lead bend in the factory, that FET turning on by slow charge build up on the gate of the order of 15 seconds fitting the failure description. I onc...

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

I did have a 200A circuit breaker but the terminals are too small for 200+ amps and it got too hot so I have temporarily removed it. My charger/BMS does disconnect the contactor if an abnormal current flows. It is quicker than a fuse. Your inverter is 20% bigger than mine, so I guess it could draw 2...

Oh no, that is terrible. Perhaps something became loose in the transportation? Mine continues to work well. My voltage is also 26.1 when the batteries are fully charged and 23.7 at lowest. Recently I have been leaving it turned on and just using the 200A contactor to turn it on and off. By the way, ...

Re: AVASS cells 2nd lot

Okay, I have now done a run at 95amps (92 would be 0.2C). Definitely an improvement. I extracted 435.6AH. Current measured by clamp meter which was almost the same as that measured across 200A shunt. After 30mins, all cells were within +-5mV of one another. +-8mV at 3hrs. With 10mins to go, the cell...

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

Hi Harold, My daughter has a nice offgrid system. 24 * 1200AH German (BAE) GEL cells. Weight 1.7 tonnes. Their average loads are only 20 to 40 amps so the capacity is very large, due to the Peukert effect. 7kW of panels, facing North at the correct angle. THREE * 5kW SMA inverters. They have run wel...

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

Hello Harold, So you finally got it! I think the 6kW is a good choice. I am very happy with my 5kW and I have been running it at 4.9kW and it hardly gets warm. The extra kW would be useful. My old photos show that my unit has a 4 wire cable plugged into the left empty socket on your photograph and t...

Re: AVASS cells 2nd lot

Thanks Terry, Yes, 200A is quite hefty. At .43C I am getting 89% of theoretical which does compare favourably with your 80% for the Sinopoly cells plus the slightly lower temperature and the fact that my AVASS cells are only roughly matched. However, I do have them well (top) balanced. At some stage...

The charger tracks the excess solar and adjusts charge rate appropriately. 2. I carefully balanced the cells in parallel (3.500V a...

Well, here is the answer from Renault. Seems there is NO capped price for Kangoo or Zoe- which fits with them not being listed with all the other capped price vehicles and means people like Crawfords can charge what they like: "Good Morning David, Thank you for your online enquiry.

Col Crawford Motors told me today that the capped service price is $307.89 for each of the annual Zoe services. I have sent a web query to Renault to ask them but they tend to be rather slack at responses.

Does anyone have a web reference for Zoe Capped Price Servicing? In particular, what is supposed to be the first service price?
I thought I had seen it some months ago but now cannot find.

Aha, if the Leaf is $23 then Zoe will be the same.

Interesting that Zoe is 13kg lighter.

Not worth jumping up and down about it.

At least Zoe is finally on the list.
