Frequently Asked Questions About Solar PV Components
A standard system requires DC Miniature Circuit Breakers (MCB) or Molded Case Circuit Breakers (MCCB) for overcurrent protection, DC Surge Protective Devices (SPD) for lightning suppression, DC fuses for string isolation, and ATS for backup power.
DC MCBs are typically rated up to 63A/1000V DC for string-level combiner boxes, while DC MCCBs protect main DC buses and battery storage inputs up to 800A/1500V DC with higher breaking capacities.
Direct current (DC) has no natural zero-crossing point, making electrical arcs much harder to extinguish than AC. GEYA DC breakers feature special magnetic arc chutes to safely extinguish DC arcs.
Our components integrate with EMS and BMS controllers to protect battery banks, solar arrays, and diesel generators, ensuring safe power flow and fast automatic transfer during grid outages.
Our solar components comply with international standards including IEC 60947-2 (DC breakers), IEC 61643-31 (PV SPDs), IEC 60269-6 (gPV fuses), and CE directives.
