  Product Advantages Advantage 1: Safe and reliable: Relays play a role in isolation and protection, avoiding circuit failures caused by load faults and improving safety. Advantage 2: Precise control: Relays can accurately control the switching state of photovoltaic circuits, thereby achieving stable operation of photovoltaic systems and precise control of electrical energy output. Application Photovoltaic energy storage inverter system: The inverter converts the variable DC voltage generated by the solar panel into AC power. The ME109 relay, as an output isolation relay, can play a safe on-off role on the grid connected AC side of the inverter. New energy vehicles and charging station systems: ME109 relays can be used in on-board chargers for new energy vehicles, as well as in AC charging stations responsible for controlling the charging switch.
