Much like our ASHP roll call, I’d like to start a list of homeowners with battery and energy storage solutions. If you have a battery, please leave the specifics in a reply, and I’ll update this list. FOGSTAR 15kWh Seplos Mason – @hughf 2 x Seplos 14.3k kWh – @misterb GIVENERGY 3 x 8.2kWh GivEnergy – @tim441 GROWATT 6kWh Growatt – @majordennisbloodnok HANCHU ESS 10 kWh Greenlinx LFP – @skd SOLAX 4.5 kWh Solax battery – @steve81uk 2x Solax 3kw batteries (Inverter Solax x1-Hybrid-G4) - @eqwilts TESLA 2 x 13.5 kWh Powerwalls – @toodles REPURPOSED CAR BATTERIES Nissan Leaf (16kWh) – @kenbone

Solaredge Energy Bank DC coupled

10 kWh (9.7 usable).

Nissan Leaf 30 kWh with Indra V2G charger (hacked of course) giving a usable 21 kWh of battery storage.

Both are integrated with our Home Assistant based HEMS to allow everything to play nicely together.

I love that!

Unfortunately there doesn't appear currently to be a V2G available on the market (the ones out there are, I believe, all associated with trials). Once one comes out I'm sorely tempted to replace our 'second' car (a petrol fiesta) with an ageing leaf (I dont yet have a battery, other than the one in our Kia e-niro which, sadly, isnt bidirectional).

Tesla PW3 (13.5kW) and Gateway for full home backup.

Samsung 12kW gen6 ASHP with 50L volumiser and all new large radiators. 7.2kWp solar (south facing), Tesla PW3 (13.5kW)
Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.

Battery 1 x 5kWh Growatt, would consider a second when prices soften

I don't have a Hybrid Inverter ( which has the H, SPH)

Growatt PV Grid Inverter MIN 5000TL-X

SPA 3000TL

Growatt AC Coupled Inverter SPA 3000TL BL

supplied and fitted by my home solar who I’d recommend getting a quote from.

@batpred I'm looking at Fogstar batteries with Solis as an alternative to Dyness, how do you find them?

I have Solax X1-AC with 5.8kWh. Last month we installed Solis 3P Hybrid with a fabulous Dyness HV stack. next project will probably be single phase Solis with either another Dyness stackable or the Fogstar.

Most of my findings on batteries are in the thread that this link points to. Regarding the inverter, the Solis hybrid exceeded my expectations.
