Plan the install

Space, code and wiring

A clean garage with a Savant Power Storage 20 beside an EV

Space

About 75 in of wall per block: 11.8 in on the closed side, the 25.6 in cabinet, and a 37.6 in bay for battery loading and the second inverter.
36 in clear in front of the gear.
Cabinets come left or right entry, so two blocks can share a loading bay.

Code

40 kWh max inside the house, 80 kWh in a garage (IRC R328.5).
3 ft between battery units unless UL 9540A data allows less.
Smoke alarm in the room. Utah adds a battery sign on the outside of the house.

Wiring

Grid and load combiner panels on parallel systems. 100 A max breaker per inverter.
Equal conductor lengths per unit. Never cross L1 and L2 between units.
Wired Ethernet to each inverter. One E-Stop whip to every inverter.
