Why Buy It as a Kit

Built for Outdoors

The 18kPV is NEMA 4X rated and the WallMount battery is IP65 all-weather rated, so the system installs outside without a dedicated equipment room.

12kW of Real Output

12,000W continuous split-phase output with 200A grid passthrough covers whole-home backup loads.

Bifacial Solar Included

18 Seraphim 440W bifacial panels (7.92kW) add rear-side production on top of the front-face rating.

Storage That Scales

The WallMount platform parallels additional batteries later, so storage can grow past the starting 14.3kWh.
