Waterproof Home Photovoltaic Combiner Box / Solar Junction Box For Power Plant
Anti reverse solar panel combiner boxes 8 strings ,backflow preventing blocking diode SCB with full protection for power plant and residential use
Quick Detail:
for blocking diode used in combiner box, usually for big solar power plant ,as there is no shade nearby so voltage of all strings are almost the same ,the power will not reverse to other strings.
for small solar system ,there may be installed near the tree or the building ,some times if there is shade on some of the panels ,these shade covered strings panels may not work as designed ,and the output voltage of different strings may be much different, for the strings no shade ,instead of output to the inverter ,the power may be reverse back to the shade covered strings, and damage the system .Also it will cause waste the power. To prevent the reverse of the power, we suggest using anti reverse diode on those residential systems.
Description:
High quality multi-strings PV combiner box for solar power system
The PV combiner box is used for connecting serial PV arrays into combiner box in parallel , it’s used together with controller, DC power distribution cabinet , solar inverter and AC power distribution cabinet etc
to consists of a completed solar power generation system . In order to improve the system’s stability and
practical applicability ,we collocate the PV dedicated DC lighting protection module , DC fuses and break etc
inside the PV combiner box , and It can detect the system parameters , also very convenient for customers
get the information on solar cellswork situation,thereby to promise the solar power generation system bring into
the max effect .Performance featuresSwitching on multi-strings PV series at the same time available ,
Outdoor installed usage is available ,Using PV dedicated DC fuse and lighting protection module,
The current of each road can be monitored with 485 communication moduleincluded ,
finalizing remote monitoring and management
