SAJ H2-12K-T3 (12 kW three-phase hybrid inverter)
Description
Independent 3-pitch solar optimization with zero DC clipping.
SAJ H2-10K-T3 is a 10 kW commercial-grade three-phase hybrid inverter with 3 independent 40 A MPPT channels and 200% DC oversizing (20 kWp), engineered to harvest complex multi-pitch roofs and deliver heavy 50 A battery throughput.
3 Independent 40 A MPPT Trackers
Eliminates string mismatch across 3 distinct roof pitches, accepting 6 strings of high-power bifacial modules.
20,000 Wp Massive Solar Intake (200% Ratio)
Massive DC capacity ensures rapid battery charging and full daytime self-consumption even on overcast days.
50 A High-Rate Battery Interface
Delivers up to 10 kW direct DC battery charging across a wide 180–800 V storage window.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase equipment without drawing expensive grid electricity.
More product details
Multi-pitch residential roofs (East, South, and West) suffer severe mismatch losses if forced into standard 2-MPPT inverters. The H2-10K-T3 features 3 independent 40 A MPPT channels (Isc 50 A) to optimize 6 strings of modern 600W+ bifacial modules.
- 3 MPPT channels allow dedicated tracking for 3 distinct roof aspects with zero inter-string mismatch.
- Absorbs up to 20,000 Wp of solar generation, routing daytime power directly into household loads and 50 A storage banks.
- Wide MPPT operating window (180–900 V) optimizes harvest across extreme temperature swings.

Faster battery charging with dynamic single-phase load compensation.
Featuring a heavy-duty 50 A battery interface (180–800 V) and 100% phase-unbalanced capability, the inverter charges storage rapidly while eliminating grid import penalties on asymmetric domestic loads. 50 A charge/discharge throughput tops off 10–25 kWh battery stacks faster during brief midday solar peaks. Dynamically shifts up to 100% of capacity onto a single heavily loaded phase to prevent utility grid purchases. IP65 cast-aluminum casing allows clean indoor utility mounting or outdoor sheltered installation (-40 to +60 °C).
40 A into each of three MPPTs.
Six strings at high module current stay on this chassis. The H2 T3 datasheet is 40 A per tracker - not the 10/20 A slogan from other H2 ranges.
Two ports for the B2 stack.
Charge and discharge at up to 50 A into an 180-800 V LiFePO4 window through the BC2-HV1 control module.

Project scenario
Large Residential Estates with 3 Roof Pitches (15–20 kWp PV)
Detached homes with East, South, and West roof pitches requiring dedicated string optimization on a 10 kW grid connection.
3 MPPT channels eliminate the need for external DC optimizers, while 20 kWp DC intake ensures rapid battery charging on cloudy days.
- BoundaryIf the roof has only 1 or 2 pitches and array size is under 15 kWp, step down to the HS2-10K-T2-X (2 MPPTs) to save equipment cost. * When to Upgrade to H2-15K-T3: If total solar array exceeds 20 kWp (up to 30 kWp) and continuous AC load exceeds 10 kW, step up to the H2-15K-T3. ---

Why choose the H2-10K-T3 over the standard HS2-10K-T2-X?
3 MPPTs (vs 2 MPPTs), 200% oversizing (20 kWp vs 15 kWp), and 50 A battery throughput (vs 30 A). * SAJ HS2-10K-T2-X: Residential unit with 2 MPPTs (16 A each), 15 kWp solar intake, and 30 A battery port. Best for standard 1 or 2-pitch roofs. * SAJ H2-10K-T3: Heavy-duty commercial-grade platform with 3 MPPTs (40 A each), 20 kWp solar intake, and 50 A battery port. Best for complex 3-pitch roofs and high-capacity battery stacks.
What is the maximum continuous AC export current on this model?
15.9 A max output current; 20 A or 25 A 3-pole circuit breaker. The H2-10K-T3 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 circuit breaker (MCB) on the main distribution panel is standard for European installations.
