Too many options.

[Beelbeebub]

Am looking at a solar & battery setup.

 

The panels bit is easy - as many as we can fit as they are cheap now.

 

The harder part is the inverter and battery.

 

We've had various quotes from different installers all recommending different brands!

 

So far

 

Tesla PW3

Sigenergy Sigenstor

GivEnergy

Solax

Puredrive/Duracell

 

TBH The powerwall has got a good rep but I can't bring myself to go for it given <gestures out of window>

 

The Sigenstor looks good on paper (and physically) but is fairly new and towards the pricey end

 

I've heard conflicting stuff about Givenergy and Solax but like the fact Givenergy is UK based

 

I know nothing about Puredrive apart from they are apparently now the Duracell units and are also UK based

 

Has anyone got any experience with any?

 

Things like reliability, customer support etc

When I started looking, my aim was the whole house could run off the battery with or without grid power. So inverter can do 6kW continuous if required.

 

Ended up GivEnergy AIO. It's an AC coupled battery, so PV has standard cheap string inverters. But with the AIO, the PV continues to generate in a power cut.

Mine has been in since September 2023. No issues so far. But have asked a couple of configuration questions, and got swift response

One thing to take into account if you intend to install a hybrid inverter, i.e. one that has both the panels and batteries on the DC side, then even if you have a mega PV array, all that can go through the inverter is it's maximum spec.  6kW continuous seems to be about what folks are installing but if you were thinking of a lot more PV, then you should have separate inverters for the PV and the batteries.

 

Also, I guess if you are looking for a hands off install, then you'll be being quoted systems like Tesla and Givenergy etc.  If you're planning on self installing, then there are a lot of other very competitive options out there.
