The difference between photovoltaic energy storage inverter and off-grid inverter

2025-05-30

Application scenarios

‌Off-grid inverter‌: Mainly used in remote areas, islands, communication base stations and street lights without grid coverage.

 It does not need to rely on the external power grid, can work independently without the grid, and provide a stable power supply. ‌

Energy storage inverter‌: Usually used in places where a stable power supply is required, such as data centers, hospitals, etc. 

It can switch to energy storage mode when the grid fails to ensure uninterrupted power supply to critical loads. ‌Functions and design features


‌Off-grid inverter‌: ‌

Independent power supply‌: 

In the absence of a grid, the off-grid inverter can work independently, generate electricity and store electricity through photovoltaic modules for load use. ‌

Strong adaptability‌: Able to cope with various load types, with fast response and strong anti-interference capabilities. ‌

Emergency power supply‌: Commonly used in power outage emergencies, providing reliable backup power supply‌2. ‌


Energy storage inverter

Bidirectional conversion: Energy storage inverter can not only invert DC into AC, but also rectify AC into DC, realizing bidirectional flow of electric energy. 

Intelligent management: With intelligent management and protection functions, it can monitor the status of equipment in real time, make automatic adjustments and optimizations, and ensure safe operation of the system. 

Efficient and stable: 

It adopts advanced power electronics technology and control strategies to achieve efficient and stable power conversion and reduce energy loss and cost.
