ICHYTI solar pv isolator switch Principle

1. If the installer does not first cut off the input wiring of the battery panel and inverter and plug and unplug the DC terminals when installing the photovoltaic system, DC power may enter the DC side of the inverter, which can cause a risk of electric shock to personnel and may also damage the inverter and other back-end equipment.

2. In photovoltaic power plants, inverters are the core equipment. To ensure sufficient power generation time, the inverter cannot have a start stop button. As long as there is sunlight, even in rainy weather, the solar panels can generate electricity, and the inverter will automatically work. However, this also poses a problem. When replacing or repairing the inverter, although the AC side has been disconnected through the installed AC circuit breaker, there is still power on the DC side. If the inverter cannot isolate direct current from the solar panel, there is a risk of electric shock and equipment damage.

3. At present, most inverters on the market do not have electrical isolation internally, and there is a backflow from the AC side to the DC side, which may lead to electric shock hazards during maintenance when physical isolation of the DC power cannot be achieved.
