Description
The 3S series brings the premium S platform to three phases. It works with 48 V LiFePO4 batteries (simpler and safer than high-voltage packs), accepts up to 800 V on the PV input and supplies three-phase loads from the grid and from the battery during an outage.
Best for
Homes with a three-phase connection, heat pumps, farms, workshops and commercial premises.
