Product Features of the 6 String PV Combiner Box
Constructed to handle the most demanding multi-array commercial configurations, this 6 String PV Combiner Box integrates premium surge protection and heavy-duty MCB isolation within a highly durable polycarbonate housing.
- Massive Array Integration: Efficiently combines six separate PV strings into dual high-capacity outputs, significantly optimizing your solar combiner box 6 string configuration for large-scale energy harvesting.
- Heavy-Duty MCB Protection: Replaces standard isolators with a powerful 1000V/63A DC Miniature Circuit Breaker (4-Pole) to actively interrupt severe overcurrents and strictly isolate the circuit.
- Advanced Surge Defense: Equipped with two Type 2 40kA DC surge protective devices (SPD) to instantly suppress damaging voltage spikes across both independent dual circuits.
- Individual String Isolation: Houses twelve 20A (10x38mm) DC fuses to safely interrupt catastrophic short circuits directly at the solar source for each string.
- Weatherproof Architecture: The durable PC enclosure carries a strict IP65 protection degree and an IK08 impact rating for long-term outdoor resilience against severe dust and rain.
