SPD RS485 DC Photovoltaic Combiner Box Remote Monitoring With Full Protection

SPD RS485 Photovoltaic Combiner Box Remote Monitoring With Full Protection

Anti reverse solar panel combiner boxes 2 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.
