Product Description

The smart photovoltaic DC combiner box is used to connect the photovoltaic array and the inverter, providing lightning protection and overcurrent protection, and monitoring the photovoltaic array single series current, voltage, temperature in the box and the state of the lightning arrester, circuit breaker status, intelligent photovoltaic bus box is equipped with overtemperature or photovoltaic series current is too large when the total circuit breaker trip function, effectively prevent damage caused by the external short circuit.
In the solar photovoltaic power generation system, in order to reduce the connection between the solar photovoltaic battery array and the inverter, the user can connect a certain number of photovoltaic cells with the same specifications in series to form a photovoltaic series, and then connect a number of photovoltaic series in parallel to the intelligent photovoltaic combiner box, through the DC circuit breaker output. It is used with photovoltaic inverters to form a complete photovoltaic power generation system.

Service Environment

1. Ambient temperature: -15ºC-+40ºC, the average temperature within 24 hours shall not be higher than +35ºC
2. Outdoor installation and use, the altitude is not more than 3000 meters,
3. Atmospheric conditions: The air is clean, and the relative humidity is not more than 50% at a higher temperature of +40 ° C, and a higher relative humidity is allowed at a lower temperature, such as 90% at +20 ° C, but in order to take into account temperature changes, excessive condensation may occur occasionally.
Note: When the above normal conditions of use are exceeded, the user can negotiate with the manufacturer to determine
