3 phase compatible battery storage

[markharro]

We are currently getting a quote for PV. We have 3 phase so interested in installing max 11kw instal. I have also enquired about battery storage although we prob cannot afford it. Installer has reverted

"The only 3 phase battery available at this moment is solax, and would come in at £8000+VAT for 11.6kWh of storage and a hybrid 12kW"

Can anyone explain what this means? What is the "and a hybrid 12kW" bit? Thanks

I read that as a 12kW hybrid inverter with 11.6kWh of batteries. No solar panels.

You can always install 3 single phase hybrid inverters with batteries, one per phase.

Probably works out a lot more expensive though.

Alternatively you can do a single phase AC coupled battery independent of the PV, but then you'll need to navigate G99 or G100 rules on export limits.

Solaredge do 3 phase batteries and I'd hazard a guess others do too?? http://www.windandsun.co.uk/information/solutions/on-grid-solar-pv-battery-storage-solutions/solaredge-3-phase-storedge™-battery-storage-system.aspx#.Y_Er03SnxxA

 

You might want to try other installers??

 

The hybrid inverter comment means the inverter can have PV connected and handle battery charging all in one unit.
