SAJ H2 6kW Three-Phase Hybrid Solar Inverter – H2-6K-LT2-LV

SAJ H2 6kW Low-Voltage Hybrid Solar Inverter

The SAJ H2-6K-LT2-LV 6kW Hybrid Inverter provides intelligent management of solar panels, battery storage, grid electricity, generator power, and household loads.

Designed for three-phase residential and small commercial applications, it delivers reliable 6kW output while supporting high-capacity solar arrays and fast low-voltage battery charging.

High Solar Input Capacity

The inverter supports a maximum recommended PV array of up to 12kW, allowing up to 200% DC oversizing. Its maximum usable PV input power is 9.6kW.

Two independent MPPT trackers help optimize solar generation from panels installed in different directions or exposed to different sunlight conditions.

Fast Battery Charging

The SAJ H2 6kW supports 40–60V LiFePO4 and lead-acid batteries. A maximum charging and discharging current of 150A enables efficient battery charging and dependable backup operation.

Two battery inputs provide additional flexibility when designing larger energy-storage systems.

Reliable Backup Performance

The inverter provides up to 6kVA backup output and supports peak off-grid power of up to twice its rated output for 10 seconds.

Its on-grid to off-grid switching time is below 10 milliseconds, helping keep essential appliances operating with minimal interruption during a power outage.

Generator and Smart-Load Support

Integrated energy management supports:

• Generator connection
• Smart-load control
• Heat-pump integration
• Solar and battery coordination
• Whole-home backup
• On-grid and off-grid operation

Flexible System Expansion

Up to 10 compatible H2-LT2 inverters can be connected in parallel for both on-grid and off-grid systems, allowing future expansion when additional capacity is required.

Durable Outdoor Design

The IP66-rated enclosure protects the inverter against dust and water. Smart cooling supports reliable operation in demanding environments, with an operating temperature range from approximately -30°C to 65°C.
