|PV Combiner Box Product Features:|
One groups of independent PV array input and output for flexible application in different connection schemes.
Use to connect to multiple PV array strings inputs, Simplify wiring between PV array and controller, protections to controller.
|2||Multiple PV input arrays each of which has a maximum current of 10A|
|3||A high voltage fuse provided for the counterattack prevention of each PV input array. It adopts the professional DC breaker, capable to withstand voltage not lower than DC1000V. So it is safe and reliable.|
|4||A special high-voltage lightning protection device for the PV module|
|5||A special high-voltage circuit breaker for output control of the PV module|
|6||A degree of protection of IP65 for meeting the need of outdoor installation|
|7||Easy and convenient installation and maintenance, long-term service life.|
|8||Can prevent countercurrent (reverse irrigation), prevent internal friction. Heat spot prevention effect.|
|9||Reliable thunderstorm& surge protection|

Solar energy system Why need to use PV combiner box
The PV combiner function: lightning protection, isolation - to prevent solar panels anti-irrigation
In general, solar panels are allowed to be used in parallel at nominal voltages, but only after proper handling.
When in parallel must ensure that solar panels will not occur between the internal friction, which requires the addition of combiner box, the combiner box can prevent counterflow (anti-irrigation), to prevent internal friction.
If you do not add confluence box, solar panels may not be placed at the same time by the sun, one is not according to one, a part of the current will be poured into the sun without solar cells, will have a hot spot effect, Solar panels will turn black and eventually burn out.
