On-grid domestic battery storage

QrizB

There's a thread over in "Consumer Rights" where someone's 8.5-year-old Pylontech batteries are supposedly failing and they're being compensated prorata under a warranty arrangement:

That's pretty elderly for a Pylontech system, I think? So fairly good news for battery durability?

I think this is the system the OP in that thread has, based around Pylontech cells and a Victron inverter:

An earlier Moixa "smart battery" system used two 25.6V batteries (8 LFP cells?) and a pair of Enphase micro-inverters:

If anyone has a Growatt SPH series hybrid inverter, there's a software configuration question over on the main Energy forum:

This thread seems as good a place as any to ask if anyone has had their power interrupted by Storm Goretti and, if so, whether their storage batteries (and any PV) have seen them through the outage.

Anyone want to share their experiences? Are there any things you'd do differently in future?

I did have some rueful thoughts about not pulling my finger out and getting my Fogstars installed, with a gateway. But not even a flicker of the lights in an area where we get cuts of varying lengths pretty frequently.

I'll have to make a new year resolution about not procrastinating, when I can be bothered to get a round tuit.

Harwich is a long way from me, but if you're in the east of Engand and fancy a used 4.6kWh BESS then this listing might interest you:
