The combiner box means that the user can connect a certain number of photovoltaic cells with the same specification in series to form photovoltaic serials, and then connect several photovoltaic serials in parallel to the photovoltaic combiner box. After the confluence in the combiner box, a complete photovoltaic power generation system is formed through the use of the controller, DC power distribution cabinet, photovoltaic inverter and AC power distribution cabinet to realize the connection with the electric supply.
The product should be placed in a well-ventilated environment, where the monthly mean relative humidity is not greater than 95% (at 20±5℃), and the air temperature is between -25℃ and +40℃, and kept away from direct sunlight. The pollution level is level 3.
When installing the collector, the instrument must be reliably grounded. The protection terminal (G), as the protection ground of the instrument, must be earthed with wires of good conductivity to ensure the good operation of the noise suppression and instantaneous protection circuit as well as the measuring accuracy.
It shouldn’t be too close to transformers, heavy-duty motors and other equipment, to prevent the unnecessary electromagnetic interference.
