Details:
In photovoltaic power generation , combiner box is a wiring device to ensure orderly connection and confluence function of photovoltaic modules. The device can ensure that the photovoltaic is easy to cut off the circuit during maintenance and inspection, and reduce the power outage range in case of photovoltaic failure.
Combiner box means that users can connect a certain number of photovoltaic cells of the same specification in series to form a photovoltaic string, and then connect several photovoltaic strings in parallel to the photovoltaic combiner box. After the photovoltaic combiner box converges, a complete photovoltaic power generation is formed by controlling and supporting the use of DC distribution cabinets, photovoltaic inverters and AC distribution cabinets, which can be connected to the power grid
Combiner boxes are divided into three types according to their functions. The first type is basic type, without reverse prevention and monitoring functions; The second type has anti reverse gear function and no monitoring function; The third type has anti reverse function and monitoring function. effect
This is a basic type, without anti reverse and monitoring functions, protection, waterproof grade ip65
