SAJ EK90 HS5-10KT3-X (10 kW three-phase all-in-one, 2026 flagship)
Description
24,000 W solar intake with heavy continuous three-phase power.
SAJ EK90 HS5-12KT3-X is a 12 kW three-phase All-in-One modular hybrid inverter unit delivering 13,200 VA maximum apparent power and 24 kWp solar intake, engineered to power luxury residences, multi-zone heat pumps, and workshops atop 314 Ah BU5 battery bricks.
12,000 VA Continuous Three-Phase Power (19.1 A Max)
Delivers heavy continuous power (13.2 kVA max) to handle heat pumps, workshop machinery, and whole-home circuits.
24,000 W Solar PV Input (200% Oversizing)
Massive solar absorption channels daytime generation into three-phase loads and high-voltage storage.
Direct Cable-Free BU5 Stacking
Mates power and communication lines directly through internal busbars with zero exposed high-voltage DC conduit.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase circuits without drawing expensive grid electricity.
More product details
Built for large electrified residences and domestic workshops, the HS5-12KT3 delivers 19.1 A maximum continuous current across L1, L2, and L3, powering multiple high-draw appliances without utility grid purchases.
- Dual independent MPPT channels (Isc 20 A) optimize multi-pitch residential stringing without current clipping.
- Absorbs up to 24,000 W of solar generation, routing daytime power directly into facility loads and BU5 storage.
- 100% phase-unbalanced output eliminates grid draw on asymmetric domestic loads.

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. Internal push-in busbars pass high-voltage power and communication directly between inverter and battery modules. Eliminates exposed high-voltage DC wiring on garage and utility room walls, maximizing residential safety. IP65 cast-aluminum casing certified for clean indoor utility rooms or sheltered outdoor walls (-10 to +50 °C).
UPS in 10 ms or less.
Protected loads see backup at 12000 W rated and 24000 VA peak when the grid drops.
BU5 under a three-phase head.
Same closed blind-mate stack as the single-phase line - 1 to 6 packs, no cable battery interface.
Technical data
Furniture-grade three-phase energy management engineered for high-demand electrified properties.
24 kWp solar intake with 13.2 kVA apparent power in an integrated 314 Ah tower.
Sized for high-consumption estates and commercial workshops, the EK90 HS5-12KT3-X handles up to 24,000 Wp of solar input across dual 16 A MPPT channels.

Project scenario
Large Estates & Multi-Family Homes (16–24 kWp PV) with Heavy Electrification
Luxury single-family properties with extensive daily electricity consumption (multi-zone heat pumps, EV wallboxes, induction cooking).
12 kW continuous AC throughput provides the power needed to run heavy loads simultaneously, while 24 kWp solar intake ensures fast battery replenishment on short winter days.
