Uses of Suntree PV Disconnect in Solar Power Systems in Kenya
1. Residential Solar Installations
- Isolates the solar panel array from the inverter and battery system for safe maintenance.
- Provides protection during power surges and voltage fluctuations.
- Prevents damage to home appliances in case of a system fault.
2. Commercial & Industrial Solar Power Systems
- Ensures compliance with electrical safety regulations for large-scale solar farms.
- Protects solar inverters, charge controllers, and battery banks from excessive voltage.
- Allows technicians to safely service solar systems without the risk of electrical shock.
3. Off-Grid and Hybrid Solar Systems
- Acts as a manual shut-off switch for DC circuits in standalone solar power systems.
- Protects solar charge controllers and battery banks from high voltage.
- Ensures safe power disconnection during extreme weather conditions like lightning storms.
4. Solar Pumping Systems in Kenya
- Used in solar water pumping for irrigation, boreholes, and livestock watering.
- Prevents damage to solar water pumps by providing a quick disconnect in case of faults.
- Helps optimize energy efficiency by isolating solar panels when not in use.
How to Connect the Suntree PV Disconnect in a Solar Power System
Materials Required:
- Suntree PV Disconnect (16A, 32A, or 63A depending on system size)
- MC4 Connectors
- PV Cables (4mm², 6mm², or 10mm²)
- Crimping Tool
- Wire Strippers
Step-by-Step Connection Guide
1. Determine Installation Location
- Install the PV disconnect switch between the solar panel array and the solar inverter.
- Mount it in a weatherproof enclosure (if located outdoors) to protect it from rain and dust.
2. Wiring the PV Disconnect Switch
- Connect the positive (+) cable from the solar panels to the input terminal of the Suntree PV disconnect.
- Connect the negative (-) cable from the solar panels to the negative input terminal of the disconnect switch.
- Run the output cables from the PV disconnect switch to the solar inverter’s DC input terminals.
3. Secure the Connections
- Use an MC4 crimping tool to securely attach connectors to PV cables.
- Ensure that the wiring matches the polarity (positive to positive, negative to negative).
4. Testing and Activation
- Turn ON the disconnect switch to allow power to flow from the solar panels to the inverter.
- Turn OFF the disconnect switch to safely cut off the power supply for maintenance.
- Verify voltage readings using a multimeter to ensure proper functionality.
