5. Konfiguracja i instalacja
The Hilitand PV Combiner Box is designed for direct installation and use. All internal wiring is pre-configured. Follow these steps for proper installation:
5.1 Montaż skrzynki rozdzielczej
- Select a suitable wall-mounted location that is easily accessible for maintenance and protected from severe environmental conditions, while allowing for proper cable routing.
- Use the provided long screws and anchors to securely mount the combiner box to the wall. Ensure the mounting surface is sturdy enough to support the weight of the box and connected cables.
5.2 połączeń przewodów
The combiner box features 4 input strings and 2 output strings. The wiring uses standard red for positive (DC+) and black for negative (DC-) cables. Terminals and wiring blocks are designed for safety and simplicity.

- Connect Solar Panel Strings: Connect the positive (DC+) and negative (DC-) cables from each solar panel string to the corresponding 'IN 1' to 'IN 4' ports on the combiner box. Ensure correct polarity for each connection.
- Connect to Inverter: Connect the positive (DC+) and negative (DC-) output cables from the 'OUT 1' and 'OUT 2' ports of the combiner box to the DC input terminals of your solar inverter.
- Grunt: Connect a suitable grounding wire from the grounding terminal inside the combiner box to a reliable earth ground. This is crucial for lightning and surge protection.
- Sprawdź połączenia: Double-check all connections for tightness and correct polarity before proceeding.
6. Instrukcja obsługi
Once installed and wired correctly, the PV Combiner Box operates passively to combine and protect your solar panel strings. Its primary function is to provide a centralized point for string connection, overcurrent protection, and surge protection.
- Początkowe uruchomienie: After all connections are secure and verified, ensure the DC isolation switch and circuit breaker inside the combiner box are in the 'OFF' position.
- Aktywuj system: Close the lid of the combiner box. Then, switch the DC isolation switch to the 'ON' position, followed by the 63A circuit breaker.
- Monitor System: Observe your inverter's status indicators to confirm proper power generation. The combiner box itself does not have indicators, but its protective devices (fuses, SPDs, circuit breaker) will activate if a fault occurs.
7. Konserwacja
Regular maintenance helps ensure the longevity and reliable operation of your PV Combiner Box.
- Kontrola wizualna (kwartalnie): Check the exterior of the box for any signs of damage, cracks, or loose mounting. Ensure all cable glands are tight and free from moisture ingress.
- Internal Inspection (Annually, by qualified personnel): With all power disconnected, open the box and inspect internal wiring for signs of corrosion, loose connections, or overheating. Check the status indicators on the surge protective devices (SPDs); if an indicator shows red or otherwise indicates failure, the SPD module should be replaced.
- Czyszczenie: Utrzymuj zewnętrzną część pudełka w czystości, usuwając kurz i zanieczyszczenia. Użyj reklamyamp ściereczka; nie używaj silnych środków chemicznych.
- Wymiana bezpiecznika: If a string is not producing power, a fuse may have blown. Only replace fuses with those of the exact same rating (15A, 1000V DC).
