Overview
Most outages last less than four hours, and most households need less than 6 kWh to ride through them. We size on the appliances that must keep running, not the whole distribution board.
A typical specification is one SM-WALL 10.5 with a 5 kW hybrid inverter, wired to a dedicated essential-loads panel. Transfer is 10 ms, so a desktop computer does not reboot.
If the site has a generator, the inverter accepts a dry contact start signal and will not back-feed the generator input.
Highlights
- Essential-loads panel keeps sizing honest
- 10 ms transfer, no computer reboot
- Generator dry-contact start
- 10-year warranty held by us
