Sunsynk warranty claims

[Isetech]

Something else to consider, the 10 year warranty for Sunsynk products are only for the cells, not the BMS. YOu have to ask yourself, will the Sunsynk BMS last 10 years ?

After doing the battery fimware upgrade, I noticed that all the cells seem to be ok (equal), which tells me that it could be the BMS that is the issue in this battery. If we hadnt compared this battery to other plants, we would have asumed that it is just the way the battery works. Once we started reviewing the graphs, that where we identified that there is a problem.

Here is something to think about: I have 10 Makita batteries, or should I say had 10, 8 left (all over 10 years old) The 2 were damaged because someone used the blower which is not star rated, which results in the battery dropping below the cutoff. I stripped the 2 batteries and identified that the BMS on the batteries where faulty. I removed the cells tested them and still use them for site torches on a daily basis.

I took the balance of the batteries to MAkita and had them all tested, the manager was quite impressed that had all done over 450 cycles, we use these batteries on a daily basis. One has 492, another 475. No faults recorded and battery SOH indicated 100%.

I can say the say for Hilti 36 VDC platform, the 36 VDC Hilti batteries are a waste of money. The worse part is you cant even strip the cells because of the way they assemble the batteries At R15 000 ex vat I certainly will not be wasting another cent replacing them.

Few other things to also consider:
A company gives a 5/10-year warranty ... maybe an idea to check the company's registration, because very few companies last 5 years in business, and even fewer last 10 years.
Or they change the warranty ... we had a Duretherm geyser with a 10-year warranty. After 9.5 years it starts leaking. Guess what? No warranty. In the preceding 9.5 years they changed the warranty terms. Want to argue, go to court the installer said, head hung low.
Another thing I look at. If I have a 5/10-year warranty, and I sell the item or house it is installed in, like a solar system, does the warranty fall away? Most do, as it is only for the first owner that gets the 5/10-year warranty.

The only company that I know of where the warranty follows the item is Victron. No one else does this that I'm aware of.
In other words, I can buy any 2nd hand Victron product from anywhere, quickly check the remaining warranty on it, and if there still is a warranty left, I can have the item replaced under that warranty, even being the 2/3/10th buyer.

So personally, a 5/10 year warranty ... I take it with a pinch of salt.

Going onto solar panels and their wot, 20/25 year warranties ... will that company still be around that 1) sold/installed them to me and 2) manufactured them?

Warranties are only worth anything when you have to have an item replaced and it gets done. Anything else is "sales jargon".

We still havent finalised this issue, however I hear there is good news for people who have issues with Sunsynk products in future months.

It sounds like Susnynk have realised that their support is something that they needed to improve drastically, lets see what haapens.

Just read today a post on another forum from a reputable national installer, I quote:

Sunsynk failures might lead to a 2-month repair/exchange time.
