20 A high-current tracking with 200% solar oversizing.
Modern large-format solar panels produce operating currents exceeding 14 A. The HS3 features dual 20 A MPPT channels (Isc 25 A) to capture 100% of solar generation across 20 kWp arrays. Dual 20 A MPPT channels optimize multi-pitch residential stringing without current clipping. Wide MPPT window (180–900 V) optimizes harvest across extreme seasonal temperature swings. IP65 cast-aluminum casing certified for clean indoor or sheltered outdoor installations (-40 to +60 °C).
30 A into BU3.
Discharge current reaches the platform maximum while the battery window stays 380-500 V.
10 kW backup on three phases.
Backup power matches the AC rating on the same IP65 slim chassis.
Technical data

Project scenario
Large All-Electric Single-Family Residences (14–20 kWp PV)
Modern detached homes equipped with a 3-phase air-to-water heat pump, induction cooktops, and high baseline domestic loads seeking a single-column All-in-One system.
10 kW continuous AC throughput provides the power needed to run heavy domestic loads simultaneously, while 20 kWp solar intake ensures fast battery replenishment on cloudy days.

SAJ HS3 Three Phase All-in-One datasheet (UK, EN) SAJ HS3 5-12K T2 Three-Phase Battery Storage Datasheet EN SAJ HS3 (3K-12K) T2 Three-Phase ESS User Manual (EN, EU)Product questions
What size AC circuit breaker is required for the HS3-10K?
3-pole 20 A or 25 A MCB; 5 × 4 mm² copper cable. The HS3-10K delivers a nominal continuous output current of 14.5 A per phase (max output current 15.9 A @ 400 V). A 3-pole 20 A or 25 A miniature circuit breaker (MCB) is standard for European installations.
What battery capacity is recommended for this 10 kW model?
Stacking 3 to 5 BU3 modules (15.0 kWh to 25.0 kWh). To support whole-home backup and deep winter solar buffering, pairing this 10 kW unit with 3 to 5 BU3-5.0-TV2-PRO modules (15.0 to 25.0 kWh) provides the ideal balance between high power throughput and multi-day energy autonomy.
