Anker SOLIX F3800

The pick if raw output matters — 6,000W handles things the DELTA Pro 3 can't on a single unit. Slightly lower cycle life and a hefty footprint are the trade-offs.

Bluetti AC300 + B300K

Splitting the inverter and battery into separate units is the point: the AC300 acts as a 24/7 UPS with 20ms switchover, and you scale storage independently by adding B300K modules. A flexible modular alternative to fixed-capacity flagships like the DELTA Pro 3.
