SAJ H2-15K-T3
Description
Multi-pitch commercial tracking with zero DC current clipping.
SAJ H2-20K-T3 is a 20 kW commercial three-phase hybrid inverter delivering 22,000 VA maximum apparent power and 40 kWp solar intake across 3 independent 40 A MPPT channels, engineered for commercial workshops, agricultural facilities, and heavy daytime machine loads.
40,000 Wp High-Throughput Solar Intake (200% Ratio)
Absorbs large commercial rooftop arrays, powering daytime machinery and 50 A battery charging simultaneously.
3 Independent 40 A MPPT Trackers
Eliminates string mismatch across 3 distinct warehouse roof pitches, accepting 6 strings of high-power bifacial modules.
22,000 VA Apparent Three-Phase Output (31.9 A)
Drives heavy three-phase industrial machinery, ventilation systems, and emergency sub-panels.
100% Phase Unbalanced Output
Dynamically diverts power to heavily loaded single-phase equipment without drawing expensive grid electricity.
More product details
Sprawling commercial roofs with 3 distinct pitch orientations suffer heavy mismatch losses if combined on fewer trackers. The H2-20K-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 40,000 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 20–40 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).
20 kW into the works.
Rated output and 22 kVA max cover commercial daytime bands that outgrew 15 kW without jumping straight to the DE 30 kW conversation.
Dual-port B2 interface.
50 A into 180-800 V LiFePO4 through BC2-HV1 - battery growth stays on the listed path while the roof takes 40 kWp.
Technical data
Heavy-duty commercial energy management engineered for manufacturing workshops and multi-pitch roofs.

Project fit
Where this model fits.
Scenarios that show which projects the SAJ H2-20K-T3 belongs in, what to verify before quoting, and when another model is the better pick.
Project scenario
Commercial Workshops & Agricultural Barns (25–40 kWp PV)
Metal fabrication workshops, auto repair garages, or agricultural operations running three-phase compressors and ventilation fans.
20 kW continuous AC output handles heavy equipment startup inrush, while 40 kWp solar intake ensures rapid battery charging and full daytime self-consumption.
- BoundaryIf total commercial solar capacity exceeds 40 kWp (up to 50–60 kWp) and continuous facility demand exceeds 20 kW, step up to the H2-25K-T3 or H2-30K-T3-DE. ---

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 H2-20K-T3?
40 A or 50 A 3-pole industrial circuit breaker; 5 × 10 mm² to 5 × 16 mm² copper cable. The H2-20K-T3 delivers a nominal continuous output current of 29.0 A per phase (max output current 31.9 A @ 400 V). A 3-pole 40 A or 50 A industrial circuit breaker (MCB/MCCB) on the main distribution panel is standard for European installations.
Can the H2-20K-T3 handle unbalanced single-phase machinery in a workshop?
Yes. 100% phase-unbalanced output shifts power to loaded phases. If a commercial workshop draws 8 kW on Phase L1 and only 1 kW each on L2 and L3, the H2-20K-T3 dynamically directs internal inverter power to supply 8 kW directly on L1, keeping net grid electricity import at zero and eliminating peak demand fees.
