The latest SAJ 12kW Three Phase Hybrid Inverter price in Pakistan is Rs. 446,250/- updated on October 28, 2026.
The SAJ H2-12K-LT2 is a 12kW three phase hybrid inverter from SAJ’s H2 low voltage series. It works with both LiFePO4 and lead-acid batteries. It can also store energy from a diesel generator. SAJ positions the H2 series as a cost-effective choice for entry-level storage systems. With two MPPTs and 12kW of rated output, it suits homes on a three phase grid.
SAJ 12kW Three Phase Hybrid Inverter with 200% PV Oversizing
This inverter accepts up to 24000Wp of solar panels, which is 200% of its rated AC power. Its maximum PV input power is 19200W, and its MPPT voltage range is 160-950V. Its first MPPT accepts up to 40A of input current and the second up to 20A. As a result, it pairs well with today’s high-power solar panels.
Fast Charging for Lithium and Lead-Acid Batteries
The SAJ 12kW three phase hybrid inverter charges and discharges batteries at up to 240A. It supports a 40-60V battery voltage range for both battery types. For lithium storage, SAJ’s user manual lists its own B3-5.0-LV battery as compatible. Therefore, confirm compatibility before you pair a battery from another brand.
Whole Home Backup with 75A Bypass
During a power cut, the inverter switches to backup in under 10ms. It then supplies up to 12000VA of backup power. In addition, it can deliver twice its rated power for 10 seconds. A 75A bypass lets it support whole home backup. Its output is also 100% unbalanced, so each phase can supply up to 50% of rated power.
Generator, Smart Load and Parallel Support
SAJ integrates energy management for a generator, heat pump, solar system and smart load. You can also connect up to 10 inverters in parallel for on-grid and off-grid operation. Multiple batteries can run in parallel as well. Furthermore, the elekeeper app lets you monitor the system. Communication options include CAN, RS485, Wi-Fi, 4G and LAN.
Built for Tough Conditions
The H2-12K-LT2 carries an IP66 rating and runs from -30°C to +65°C, with derating above +45°C. Because it keeps working in high temperatures, it suits hot summers in Pakistan. Overall, this SAJ 12kW three phase hybrid inverter reaches 98.0% maximum efficiency. SAJ backs it with a 5-year warranty, and a 10-year warranty is optional.
