Seems worryingly cheap! Check what size the breakers/fuses are, I bet it won't do 10kVA when the input voltage is at minimum.

What went wrong?? (please don't name your previous contactor) If you don't score here in a couple of days, PM me and we'll move to the HH dedicated forum. Photos of the existing works may be useful.

And the conclusion from that article: -

I've had a couple of those, all were fixed by the lovelies in the Kerry office. I have no idea what they did (there was lots of typing and discussions) but I went away with a receipt and the items were logged as returned by Lazada.

It definitely should be Lisa Simpson!

We had one minor bump in the road in that I had to return to the bank to get online banking working, 10 minutes (and more photocopies) and we're good to go.

If you are worried about duty / tax then ask if your seller can ship "DDP" (Delivery Duty Paid) which means that there's nothing to pay at this end, everything is pre-cleared by Thai customs.

Where in Thailand are you located? Your local university may well have testing facilities, or if not, may be able to point you in the direction of a reputable lab.

Do you have links to these reports please. It's always good to have all sides of the discussion.

Did you get anything back from Luyuan? Our packs are behaving well and staying well in-balance (we do have the optional active-balancers).

Since I have to replace the cells in a couple of our deco lights I need to order a few 18650s. Which of the plethora of cells in their shop would you recommend as known good??

In our quest for more power, "more volts Igor, more volts!!" we stuck 6 x 445W panels on the patio roof. We are now up to 51 panels totalling 18kWp. The roof slopes to the east and the panels are shaded by the house later in the day but their performance has actually been rather better than I anticipated. The 4 baby panels power our floodlights.

Back in April this year we got two new 280Ah x 48V (about 14kWh) packs from China for USD 3,774 the pair including DDP shipping (no duty or tax to pay at this end). Unless your second-life packs are very competitive is it worth the risk?

It's also worth noting that many of the used packs (including the Nissan Leaf) use the older NMC chemistry. NMC packs have a rather greater propensity for going "whoosh" than the newer (and now favoured for EVs) LiFePO4 chemistry. Personally, I would rather not have either chemistry inside my home (our 70kWh of LiFePO4 storage is in its own fire-resistant shed) but having an NMC pack inside your living space would be a definite no-no. EDIT For any type of ESS it's worth remembering that a "reasonably sized" i.e. 14kWh pack contains as much electrical energy as about 1.5litres of petrol/gasoline. Treat your energy storage in the same way as the gas can for your mower!

MG have modified their battery warranty (even for existing owners) to be unlimited mileage. https://www.bangkokpost.com/business/motoring/2829412/mg-announces-extended-lifetime-warranty-for-four-models and here (use Google Translate) https://brandinside.asia/mg-lifetime-warranty-battery-ev/ I expect other manufacturers to follow suit forthwith.
