5~6k5 Single-Phase Low Voltage Off-grid Energy Storage Inverter
The SOSEN SSA-HL5~6.5K-P1EU_DO Pro is a 5–6.5kW hybrid off-grid inverter engineered for reliable power independence. Delivering pure sine wave output with up to 9kW of solar input capacity, it intelligently manages energy flow between your solar panels, battery bank, and connected loads — keeping critical appliances running even when the grid goes down.
- Up to 9kW solar input, with 500V voltage and 27A current
- MPPT control with configurable PV/grid priority settings
- Dual AC outputs for critical and non-critical load prioritization
- 6.5kW output in a smaller, lighter chassis for flexible installation
- Built-in WiFi & LCD for remote/local monitoring
- Outdoor-ready with IP54 rated against dust and water splashes

Safety, Reliability, Compatibility, Efficiency
SSA-HL5~6.5K-P1EU_DO Pro
5~6.5kW | Single Phase | Low Voltage | IP54
The SSA-HL5～6.5K-P1EU_DO Pro is a compact off-grid hybrid inverter series with up to 9 kW PV input and dual AC outputs for flexible loads management. Equipped with smart MPPT controller.
Its compact and IP54-rated enclosure makes it equally at home in a garage, utility room, or outdoor installation, while built-in WiFi and an LCD put real-time system monitoring right at your fingertips.
How the Off-Grid System Works
As the core of the system, the inverter intelligently manages energy from PV, battery, and grid or generator backup.
It uses solar energy to power loads first, stores surplus power in the battery, and automatically switches to backup sources when needed — helping ensure a reliable and efficient power supply.
For added reliability, the system can also work with the grid or a generator as a backup power source. This helps ensure continuous operation, especially in remote areas or places with unstable power supply.
Key Benefits
- Higher solar self-consumption
- Reliable backup power support
- Smarter energy distribution
- Better energy independence
- Easy remote system monitoring
