This power storage system consist of 10ea. POWERWARE VRLA Batteries, Model # PWHR12280W4FR with a floating voltage of 13.5 to 13.8V @ 280 Watts.
The batteries are grouped into two levels (top and bottom).
The on-board 2000Watt AC Inverter is feed from one or both of the battery banks through the use of two High current T-handle switched.
This allows the charging of one bank while using the other bank of batteries to run the inverter.
The on-board Schumacher SSC-1500A 15 Amp AGM Battery charger is connected through two switches. One switch is connected to the top bank of batteries and the other to the bottom bank of batteries.
This configuration allow the selection of which or both banks of batteries to charge.
I wired all of the batteries using 6AWG cables.

This isolates all house wiring from the commercial power.
Then using a 110 to 220 modified jumper which applies 110VAC to both sides of the 220 Circuit and the neutral to connect to the main house power.
Power up the inverter.
Turn ON one circuit at a time watching the Inverter load indicator.
Keeping in mind the more load you apply the shorter the battery backup time will last.
I only turn on pre-determined breakers which I have identified as necessary.
