Koneksyon fil elektrik
The combiner box is pre-wired internally. Connect your solar panel strings to the input terminals and the output to your inverter. Refer to the wiring diagram for correct connections.
- Connect the positive (+) and negative (-) cables from each solar string to the corresponding input terminals (IN 1, IN 2, IN 3, IN 4). The box supports up to 4 input strings.
- Connect the output cables from the combiner box (OUT 1, OUT 2) to your inverter. The box has 2 output strings.
- Asire w tout koneksyon yo sere epi byen fèm pou anpeche kontak ki lach ak danje potansyèl.
- The built-in grounding wire connector should be properly connected to your system's ground.

Enstriksyon Operasyon
Once installed and wired correctly, the PV Combiner Box operates automatically to combine and protect your solar strings. The internal components provide overvoltage, surkouran, ak kout sikwi pwoteksyon.
Operasyon disjoncteurs
The 63A circuit breaker provides overvoltage and overcurrent protection. In case of a fault, the breaker will trip, disconnecting the load circuit. To reset, identify and resolve the fault, then push the breaker switch back to the 'ON' position.

Pwoteksyon vag
Segondè voltage arrester provides surge protection, diverting excess voltage to ground during lightning strikes or other surge events, protecting your connected equipment.

Antretyen
Antretyen regilye asire lonjevite ak pèfòmans optimal PV Combiner Box ou a.
- Enspeksyon peryodik: Annually inspect the box for any signs of physical damage, corrosion, or loose connections.
- Netwayaj: Keep the exterior of the box clean from dust and debris. Use a damp twal; pa sèvi ak pwodui netwayaj abrazif.
- Verifikasyon Tèminal: Periodically check all terminal connections for tightness. Loose connections can lead to overheating and system inefficiency.
- Ranplasman Fuse: If a fuse blows (15A fuse), replace it with a fuse of the same rating and type. Always disconnect power before replacing fuses.
Depanaj
Seksyon sa a bay solisyon pou pwoblèm komen ou ka rankontre.
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Pa gen kouran ki soti nan bwat konbine a. | Circuit breaker tripped; Blown fuse; Loose wiring connection; No input from solar panels. | Check and reset circuit breaker; Inspect and replace blown fuses; Verify all wiring connections are secure; Check solar panel output. |
| Water ingress into the box. | Improperly sealed cable glands/gaskets; Damaged enclosure. | Ensure all cable glands are tightened and gaskets are properly seated; Inspect the enclosure for cracks or damage and replace if necessary. |
| Overheating of components. | Loose connections; Overload; Insufficient ventilation. | Tighten all electrical connections; Ensure total current does not exceed box ratings; Verify proper air circulation around the box. |
