The Hinen 3.3 kW Off-Grid Inverter (Model N3300S) is engineered to provide reliable and seamless off-grid power conversion for standalone solar systems and backup applications. Its pure sine wave output delivers stable and clean AC power that is safe for sensitive electronics, appliances, and household loads.

Designed for both efficiency and durability, this inverter combines a high-frequency inverter with an integrated MPPT (Maximum Power Point Tracking) solar charge controller to ensure optimal use of solar energy while managing battery charging intelligently.

Intelligent Off-Grid Energy Management

Equipped with an integrated MPPT solar charge controller, this inverter automatically tracks the solar array’s optimal power point to maximise harvested energy. The inverter’s intelligent energy management system allows configurable priority between solar and AC input sources, responsive load management, and seamless switching between power sources.

With a rapid transfer time of under 10 ms, the inverter ensures minimal interruption when switching from one power source to another, making it suitable for critical loads and everyday appliances.

Pure Sine Wave Output & Protection

The pure sine wave AC output provides clean and reliable electricity that closely resembles grid power, supporting sensitive loads such as computers, TVs, refrigerators, and other appliances. The inverter also includes built-in protections against overload, short circuit, deep battery discharge, and other fault conditions, enhancing safety and reliability for long-term use.

Battery Compatibility & Flexibility

This off-grid inverter supports a range of battery types, including lead-acid and lithium batteries, with lithium activation functionality where applicable. The wide compatibility makes it easy to configure within existing or new off-grid solar systems.

The integrated “cold start” function allows the inverter to power loads directly from the battery even when AC input is unavailable, enhancing its utility for backup power scenarios.

Suitability and Applications

The Hinen 3.3 kW Off-Grid Inverter is suitable for a variety of small to medium off-grid scenarios, including:

• Residential off-grid homes and cottages

• Small cabins and rural electrification

• Load-shedding and backup power systems

• Mobile or remote solar installations

Its compact design and robust feature set make it a versatile choice for both DIY solar setups and professional installations.
