The HSI-351 is a versatile and high quality off-grid solar inverter designed to provide clean and stable energy for residential, remote and mobile power applications. With advanced features and robust performance, it is ideal for users seeking an efficient and reliable off-grid power solution.

At the heart of the HSI-351 is its pure sine wave output, which provides smooth, grid-quality power suitable for sensitive electronics such as laptops, televisions, lighting systems and household appliances. Unlike modified sine wave inverters, pure sine wave ensures noise-free operation and better compatibility with a wide range of devices.

The inverter supports both 50Hz and 60Hz frequency settings, allowing users to easily adapt the system to local grid standards or specific load requirements. This flexibility makes the HSI-351 suitable for global markets and a wide range of applications.

One of the outstanding features of the HSI-351 is its built-in PWM (Pulse Width Modulation) solar charge controller, which simplifies solar system installation and reduces the need for external components. The PWM controller ensures stable and efficient charging of solar panels, increasing battery life and system reliability while minimising energy loss.

Designed for 12V battery systems, the HSI-351 is compatible with various battery types, including lead-acid and gel batteries. It offers automatic battery charge management to prevent overcharging or deep discharging, extending the overall life of the battery bank.

The inverter is also equipped with comprehensive safety features, including overload, over-voltage, under-voltage, short-circuit and over-temperature protection. These features ensure safe and continuous operation even under challenging conditions.

With its compact size, user-friendly interface and all-in-one functionality, the HSI-351 is perfect for homes, RVs, cabins and small solar installations.
