Guida all'installazione
Istruzioni di cablaggio
The circuit breaker is designed with non-polarity, meaning the input and output terminals can be interchanged based on your system's specific requirements. Follow these steps for proper wiring:
- Connect Solar Panel Array: Connect the output from your solar panel array to the 'Input' terminals of the breaker box.
- Connect to Inverter/Load: Connect the 'Output' terminals of the breaker box to your inverter or AC load.
- Connessioni sicure: Ensure all MC Solar connectors are securely fastened and properly seated to maintain the IP67 waterproof rating and ensure reliable electrical contact.

Montaggio
The breaker box is designed for screw mounting. It can be installed directly onto a wall or suitable flat surface without requiring disassembly. Use appropriate fasteners (not included) for the mounting surface to ensure a secure and stable installation.
Operazione
The DIHOOL Outdoor Circuit Breaker Box operates as a manual disconnect switch and an automatic protective device.
- To Engage (Turn On): Push the breaker switch to the 'ON' position. This connects the solar array to your system.
- To Disengage (Turn Off): Push the breaker switch to the 'OFF' position. This disconnects the solar array from your system.
- Viaggio automatico: In the event of an overload, overcurrent, or short circuit, the breaker will automatically trip to the 'OFF' position to protect your system. If this occurs, identify and resolve the fault before attempting to reset the breaker.
- Ripristino dell'interruttore: After resolving a fault, push the breaker switch fully to the 'OFF' position, then push it to the 'ON' position to reset.
Manutenzione
Regular maintenance ensures optimal performance and longevity of your circuit breaker box. Always disconnect power before performing any maintenance.
- Ispezione periodica: Visually inspect the exterior of the box, cable entries, and connections for any signs of damage, corrosion, loose wiring, or wear.
- Pulizia: Pulisci l'esterno della scatola con un panno morbido eamp cloth. Do not use abrasive cleaners, solvents, or high-pressure water jets, as these can damage the material or compromise the seals.
- Integrità del sigillo: Ensure the transparent cover and all cable entries maintain a tight seal to preserve the IP67 rating and prevent moisture ingress.
- Verifica della connessione: Periodically check that all MC Solar connectors are securely fastened.
Risoluzione dei problemi
If you encounter issues with your DIHOOL Outdoor Circuit Breaker Box, refer to the following common troubleshooting steps:
- L'interruttore scatta frequentemente:
- Sovraccarico: Check the total current draw from your solar array and connected loads. Ensure it does not exceed the 30 Amp rating of the breaker. Reduce load if necessary.
- Corto circuito: Inspect all wiring for any short circuits between positive and negative terminals or to ground. Look for damaged insulation or exposed wires.
- Faulty Component: If the issue persists after checking for overloads and short circuits, a faulty component in your solar system or the breaker itself may be the cause. Consult a professional electrician.
- Nessuna potenza in uscita:
- Breaker Position: Ensure the circuit breaker is firmly in the 'ON' position.
- Potenza in ingresso: Verify that the solar panels are generating power and are connected correctly to the input terminals of the breaker box. Use a multimeter to check voltage.
- Collegamenti allentati: Check all MC Solar connectors and internal wiring for secure connections. Loose connections can interrupt power flow.
