1000W Hybrid Solar Inverter Low Frequency

The HSI PLUS hybrid solar inverter is a compact off-grid power core for small household energy storage. It is perfectly suited to low-power daily loads such as lighting, fans, and small home appliances. This 1000 W, 12 V unit boasts all the key features of the HSI PLUS series, including stable 1000 W rated power and 3000 W instant surge power, enabling it to handle device start-up spikes without the risk of overloading.

The integrated 30A MPPT solar charger is a particular highlight, maximising PV energy collection all day long. It supports a maximum 450 W PV array under a 12 V battery configuration and automatically tracks solar voltage between 12 and 16 V DC to minimise energy waste. With a ≤5 ms UPS transfer speed, it can seamlessly switch between grid, battery and solar power sources without causing blackouts for critical loads, making it ideal for areas with frequent power cuts.

It is compatible with gel, AGM, lead-acid and LiFePO4 batteries and adds multi-layer overcharge, over-discharge and short-circuit safeguards to extend battery lifespan. Users can switch freely between five working modes, including mains priority, battery priority and generator mode, to suit different usage habits. The optional Wi-Fi module and RS485 communication allow users to check real-time voltage, power and charging data via the mobile app at any time. With a toroidal low-frequency transformer, this HSI PLUS inverter achieves over 85% transfer efficiency, reducing long-term power loss and providing reliable, cost-effective off-grid power solutions for cabins, small villas, and rural families.
