SAJ H2-10K-T3 (10 kW three-phase hybrid inverter)
Description
Multi-pitch commercial tracking with zero DC current clipping.
SAJ H2-12K-T3 is a 12 kW commercial-grade three-phase hybrid inverter delivering 13,200 VA maximum apparent power and 24 kWp solar intake across 3 independent 40 A MPPT channels, engineered for large residential estates, workshops, and high-rate battery charging.
24,000 Wp Massive Solar Absorption (200% Ratio)
Captures abundant solar power across multi-pitch roofs, powering domestic heat pumps and 50 A battery charging simultaneously.
3 Independent 40 A MPPT Trackers
Eliminates string mismatch across 3 distinct roof pitches, accepting 6 strings of high-power bifacial modules.
13,200 VA Apparent Three-Phase Power (19.1 A)
Provides strong continuous power to run commercial equipment, HVAC, and dedicated emergency sub-panels.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase machinery without drawing expensive grid electricity.
More product details
Sprawling estate roofs with 3 distinct pitch orientations suffer heavy mismatch losses if combined on fewer trackers. The H2-12K-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 East, South, and West warehouse pitches with zero inter-string mismatch.
- Absorbs up to 24,000 Wp of solar generation, routing daytime power directly into facility 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 loads. 50 A charge/discharge throughput tops off 15–25 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).
Backup scaled with the AC rating.
12 kVA continuous and 18 kVA for three seconds cover a wider protected load than the 10K while keeping the same UPS timing.
B2 pairing unchanged.

Project scenario
Large Electrified Estates & Small Workshops with 18–24 kWp Solar
Large residential properties or commercial auto repair shops running three-phase tools and multi-split heat pumps.
12 kW continuous AC output provides the extra capacity needed to run machinery without grid draw, while 24 kWp solar intake ensures rapid battery charging.
- BoundaryIf total commercial solar capacity exceeds 25 kWp (up to 30–40 kWp) and continuous building load exceeds 12 kW, step up to the H2-15K-T3 or H2-20K-T3. ---
What Linker confirms with you
- If total commercial solar capacity exceeds 25 kWp (up to 30–40 kWp) and continuous building load exceeds 12 kW, step up to the H2-15K-T3 or H2-20K-T3. ---

SAJ H2 10-30K Three Phase Hybrid Inverter datasheet (Europe, EN) SAJ H2 Series (10-30K) T2/T3 Datasheet (EN, BEU)Product questions
What size AC circuit breaker and cable cross-section are required for the H2-12K-T3?
25 A or 32 A 3-pole circuit breaker; 5 × 4 mm² to 5 × 6 mm² copper cable. The H2-12K-T3 delivers a nominal continuous output current of 17.4 A per phase (max output current 19.1 A @ 400 V). A 3-pole 25 A or 32 A circuit breaker (MCB) on the main distribution panel is standard for European installations.
Can the H2-12K-T3 handle unbalanced single-phase loads in a workshop?
Yes. 100% phase-unbalanced output shifts power to loaded phases. If a commercial workshop draws 5 kW on Phase L1 and only 1 kW each on L2 and L3, the H2-12K-T3 dynamically directs internal inverter power to supply 5 kW directly on L1, keeping net grid electricity import at zero.
