Description

Feature

High power generation efficiency not only saves the cost of power generation, but also realizes the self-generation and self-use of power.
The output power quality is high, not only can meet the demand of the grid, but also can provide more stable and safe power for the grid.
Can be matched with different solar panels for a wide range of applications.
With a variety of protection functions such as: overload protection, short-circuit protection, over-voltage protection, under-voltage protection, etc., can effectively protect the solar panels and the safety of the power grid.
Built-in intelligent controller, realize intelligent control, effectively improve power generation efficiency and stability.
Simple and easy-to-use design, convenient daily maintenance.
