SAJ EK90 HS5-10K-S4-X (10 kW single-phase all-in-one)
SAJ EK90 HS5-10K-S4-X is the flagship 10 kW single-phase All-in-One modular hybrid inverter unit delivering 45.5 A continuous current across 4 independent 16 A MPPT channels, engineered to stack cable-free atop 314 Ah BU5 battery bricks.
- 4 Independent 16 A MPPT Trackers: Industry-first 4-MPPT single-phase residential inverter, managing complex multi-pitch roofs, dormers, and outbuildings with zero optimizers.
- 20,000 Wp Solar PV Intake (200% Ratio): Massive solar absorption channels daytime generation into single-phase domestic loads and high-voltage storage.
- 10,000 VA Full Single-Phase Backup (45.5 A): Sustains high-draw domestic single-phase sub-panels, whole-home air conditioning, and induction hobs during blackouts.
- Direct Cable-Free BU5 Stacking: Mates power and communication lines directly through internal busbars with zero exposed high-voltage DC conduit.

4 independent MPPT trackers with 20 kWp solar intake and 10 kW single-phase output.
Maxing out single-phase residential power density, the EK90 HS5-10K-S4-X features 4 independent MPPT trackers (16 A each) supporting up to 20,000 Wp of solar input. It delivers 10,000 W continuous AC power (45.5 A max), stacking cleanly on 314 Ah BU5 modular battery bricks (6.0 to 27.0 kWh) for uncompromised single-phase household energy autonomy.

4-pitch solar tracking on a single-phase residential inverter.
Modern residential properties with complex hip roofs, dormers, and detached garages cannot be optimized on standard 2-MPPT inverters. The HS5-10K provides 4 independent 16 A MPPT channels (Isc 20 A).
Furniture-grade single-column integration with internal busbars.
Stacking directly on top of BU5-6.0 / 7.0 / 9.0 kWh battery modules eliminates external high-voltage conduits, junction boxes, and messy communication patch leads.
Where this model fits.
Scenarios that show which projects the SAJ EK90 HS5-10K-S4-X (10 kW single-phase all-in-one) belongs in, what to verify before quoting, and when another model is the better pick.
Large Single-Phase Luxury Residences (14–20 kWp PV) with 4 Roof Pitches
Large single-family properties with high-capacity 50 A/63 A single-phase grid service running heat pumps, pool heaters, and EV chargers across 4 distinct roof orientations.
4 MPPT channels eliminate the cost of dozens of DC optimizers, while 10 kW continuous AC output handles heavy single-phase loads.
