Product Overview：
The grid-connected energy storage auxiliary isolation transformer for photovoltaic power generation is generally used for solar inversion, with common voltages including 800V to 400V, 380V, 690V to 400V, 540V to 400V, etc. (customizable as required); due to the low photoelectric efficiency of photovoltaic silicon panels, the transformer is specially required to have high efficiency. The photovoltaic isolation transformer is equipped with a microcomputer intelligent time controller to set daytime operation and nighttime stop for reducing no-load power loss, a temperature controller to real-timely monitor the operating temperature of the transformer, control the start and stop of the cooling fan, and automatically stop and disconnect the transformer when the operating temperature is too high to reach the set critical temperature for protecting the safety of the transformer body, a self-reset overvoltage and undervoltage protector to prevent islanding operation, a surge protector to effectively prevent lightning damage to equipment and improve the safety factor of the power generation system, and a knife switch on the grid-connected side to facilitate effective operation and maintenance of the equipment.
Key Features:
Grid-side knife switch for maintenance.
