What is the view on 2nd hand Givenergy products?
I can see a point where people move to AIO's and remove hybrid inverters and batteries soon.

I'd like to look at a 2nd battery, but the price point to benefit is massively diminished due to the solar and 1st battery covering 80-90% of needs. (I'd have gone for a 13.5 battery if there was a Giv-Bat13.5).

Also, I think there could be a market for Givenergy to allow self installed 2nd and tertiary batteries as an almost plug and play activity (mount, set dip switches, plug in, calibrate, go).

Happy to be a guinea pig in fitting 2nd hand 9.5 (or 8.2) battery to a newish system....if only that wasn't an already proven feature.

Not wishing to spend an extra £4k on another 9.5 battery, but willing to spend another £2k for a 2nd hand 9.5 one fitted.

wrighar Not sure there would be much demand for second-hand GE hybrids/batteries given the commissioning requirements.

That sort of price point is covered by their budget brand (PolarESS) so you could probably buy new at the same price as GE owners are trying to sell second-hand stuff.

Locked eco system is a blessing and a curse. Handy for compatibility and warranty all owned by GE.
Not great for second hand market as unless you have installer access the normal user is stuck hence 2nd hand values can be a bit on the poor side (I picked up a Gen 1 for £75)

It's not impossible to self commission one if you forgo app/portal access and get your hands dirty with the modbus library but depends if you want to rely solely on the likes of Home Assitant or Rubicubes app.
Ultimately commissioning doesn't really do anything you couldn't do locally if you know enough about the modbus side of things.
I've done far more personally but as I assume it would land me in hot water the code isn't shared.

hoggy If it was a case of buy (for example) a G1 inverter in case the one fitted failed then that'd make sense as they're no longer manufactured. That however would still require an electrician to fit/certify it's safe so not such a big deal getting them to commission.

For batteries? I think that ship already sailed. After owning a GE battery from new I wouldn't touch a reconditioned one with the longest bargepole imaginable. Patents have expired on the battery cell technology so everyone & their dog (including Tesla) are making them now. That's one of the reasons GE have their own budget brand.

In terms of whatever "plan" GE have for "used/reconditioned" hardware. Don't hold your breath. It'll arrive (if at all) too late to be relevant....

hoggy wow, where did you get the inverter from so cheap?

Hook eBay auction (probably got lucky with bidding but still, it can be done)
