4. Wide Input Voltage Range for Strong Adaptability

The AC input voltage range covers 90‑280V (normal mode) / 170‑280V (UPS mode), with automatic frequency adaptation (50/60Hz). Whether in areas with stable grid power or regions with frequent voltage fluctuations, the unit operates reliably, ensuring continuous power supply to critical loads.

5. Comprehensive Protection for Safety and Reliability

The product features a full suite of protection functions, including overload, over‑voltage, over‑temperature, and short‑circuit protection. In battery mode, the overload capacity is staged: 60s @ 102%‑120% load, 10s @ >120%‑200% load. An intelligent temperature‑controlled fan ensures low noise and efficient heat dissipation. With an IP21 rating, it is suitable for long‑term stable operation in dry indoor environments.

6. Intelligent Communication and Remote Monitoring

The GA-2012 comes with an LCD display that shows real‑time operating modes, load status, and input/output parameters. It offers multiple communication interfaces (RS232, RS485, CAN, Wi‑Fi), enabling remote monitoring, data logging, and diagnostics via a mobile app. It also supports BMS communication with lithium batteries, allowing intelligent interaction and coordinated management with the battery system.

7. Flexible System Adaptation

The inverter supports both lithium and lead‑acid batteries, and its 12V nominal voltage makes it compatible with most 12V battery systems on the market. Whether paired with a LiFePO₄ battery for an off‑grid storage system or with lead‑acid batteries for backup power, the GA-2012 integrates seamlessly.

Safety and Intelligent Features

1. Multiple International Certifications

The 2KW 12V Off Grid Solar Inverter holds CE and ROHS certifications, meeting EU market access standards and global environmental requirements. Its comprehensive protection design ensures safe and reliable operation across various application scenarios.

2. Intelligent BMS Communication Compatibility

Built‑in communication interfaces enable real‑time data exchange with lithium battery BMS systems via CAN/RS485 protocols. This allows monitoring of battery status, optimisation of charge/discharge strategies, and cell balancing, effectively extending the overall service life of the energy storage system.

3. Standard Protection Rating

The GA-2012 has an IP21 protection rating, preventing ingress of small objects and making it suitable for indoor use. It operates within a temperature range of ‑15°C to 60°C and a relative humidity of 5%‑95% (non‑condensing), ensuring stable long‑term performance in typical indoor environments.
