Kuwait BWX Photovoltaic Grid-connected Distribution Box
Category:
Product Description
Photovoltaic grid-connected box is a photovoltaic power station built near the user's site. The operation mode is that the user generates electricity for self-use and the excess electricity is connected to the grid: in order to maximize the protection of the safe operation of the system, ensure the safe coordination between the inverter and the mains power grid, and improve the reliability of the system and the power metering.
This product has the characteristics of high protection level, long service life, easy installation and operation. Its functions include isolation protection, overload protection, short circuit protection, surge grounding protection, over-voltage and under-voltage protection, reclosing after recovery, power generation and power metering, etc.
