The latest SAJ 6kW Single Phase Hybrid Inverter price in Pakistan is Rs. 183,750/- updated on October 28, 2026.
The SAJ H2-6K-LS2 is a 6kW single 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 6kW of rated output, it suits homes on a single phase grid.
SAJ 6kW Single Phase Hybrid Inverter with 200% PV Oversizing
This inverter accepts up to 12000Wp of solar panels, which is 200% of its rated AC power. Its maximum PV input power is 9600W, and its MPPT voltage range is 90-480V. Each of its two MPPTs accepts up to 20A of input current. As a result, it pairs well with today’s high-power solar panels.
Fast Charging for Lithium and Lead-Acid Batteries
The SAJ 6kW single phase hybrid inverter charges and discharges batteries at up to 120A. It supports a 40-60V battery voltage range for both battery types. For lithium storage, SAJ’s user manual lists its B2-5.0-LV1, B2-5.0-LV2 and B3-5.0-LV batteries as compatible. Therefore, confirm compatibility before you pair a battery from another brand.
Whole Home Backup with 63A Bypass
During a power cut, the inverter supplies up to 6000VA of backup power. In addition, it can deliver twice that output for 10 seconds. A 63A bypass lets it support whole home backup. SAJ also lists AFCI and RSD protection as options.
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 4 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 Wi-Fi, Ethernet and 4G.
Built for Hot Weather
The H2-6K-LS2 carries an IP65 rating and runs from -40°C to +60°C, with derating from 50°C to 60°C. SAJ highlights its heat resistance above 50°C, so it suits hot summers in Pakistan. It uses intelligent fan cooling, while its noise level stays below 50dB. Overall, this SAJ 6kW single phase hybrid inverter reaches 97.6% maximum efficiency. At 29kg, it is also easy to mount on a wall.
