Hi,
As i'm gradually piecing together bits for the unofficially wiki from various sources I have a few queries regarding batteries that someone on here may know the answer to.

Firstly Gen 1 Stuff: Based on this thread i've taken the values to be as per the table provided by Givenergy (so things like a single 2.6kWh battery can only do 1.25kW)
BUT it kind of contradicts itself in regards to a SINGLE 5.2kWh battery when on an AC coupled: Table says it will do 3kW no problem but Givenergy state "all batteries are limited to 0.5C" which would be about 2.6kW

So to anyone with a SINGLE 5.2 on an AC3 inverter - what do you actually get out of it charge/discharge wise.

Secondly: There is no such table for Gen 2 i'm aware of.
I can assume following the 0.5C rule that both the 9.5 & 8.2kWh batteries are good for the Gen2 3.6kW rates on their own.
It's the 5.2 and below i'm not sure on (which would follow on from the first question above)
Anyone have any data as to what smaller packs on Gen 2 Actually do (datasheets stating amps have proven to not be totally reliable source of what actually goes on internally)

Thanks in advance.

hoggy Sorry to hijack your pressing question, but I think there's a place on your wiki for this. It's a shutdown procedure for an inverter from @ToothyChris

Tim yes that can go on. I’ll turn it upside down for the restart procedure!
Must be from the new installer manual, My copy is well out of date now so I’ve not dared add bits from it as it’ll be a pain to maintain.

Correct. Version 10, 2022.

(But I am not an installer....)

@Tim it's done

Just doing one on first run calibrations as that keeps popping up again from installers not telling people what it;s going to do.
