For the actual RE system itself:
365AH @ 12V / 4.38 kWh comprised of the following:
220AH 12V 8D 'Werker', main battery
'Slaves' (charged from the main battery, either directly or via a boost converter when things are running a little tight) - These are all portable and are used to run countless equipment throughout the house:
4 x 18AH 12V SLA
4 x 12AH 12V SLA
1 x U1-3 'Lawn and Garden' 12V battery (yes, for cranking a riding lawnmower... please don't slap me too hard haha) - Obviously not rated in AH - Going to call it 25 (even though if I ever used even CLOSE to that much, I'd only do it a few times... LOL
-----
There's more, but considering these would be like including the battery in my cell phone... Although, I
do regularly charge it from the RE bank! I can't win... LOL
There are 3 other U1-3 Lawn/Garden batteries that are on the 3 'standalone' UPS units for workstations scattered throughout the house. But I don't consider these 'real', since for one, they are very specifically dedicated, and two, they are solely for use with backing up the grid.
Also, another 230AH @ 24V (5.52kWh, 4 x 230AH @ 6V in series) set for the main UPS system for the servers. I don't count them either, for the same reason.
But, if I were to be anal retentive about including ALL the lead-acid storage, I would have to call it 10.8 kWh...

EDIT - Changed this around, just didn't like how it read... Speaking of anal retentive... Yup, that's me!
