Key Installation Steps
Mounting the Inverter
- Wall or rail mounting options are available.
- Use pre-drilled holes or a TH-35-7.5 top hat rail for secure attachment.
- Leave 50 cm clearance above/below and 20 cm on sides for ventilation.
Electrical Connections
- DC Input (PV Panels)
- Requires 100–500V DC input (MPPT range).
- Use pre-fitted MC4 connectors or compatible DC plug connectors.
- Install DC isolators and surge protectors (SPDs) for safety.
- AC Output (Grid)
- Connect to a sub-panel using 3-conductor wiring (hot, neutral, ground).
- Match grid voltage (230V/230V ±40V) and frequency (50Hz/60Hz).
- Grounding
- Mandatory protective conductor (PE) connection; a second grounding terminal is optional.
Safety Measures
- Install circuit breakers for AC/DC circuits (e.g., 25A DC breaker for PV input).
- Ensure polarity correctness to avoid reverse connections.
Tools and Materials Required
- Basic Tools: Screwdrivers, wire strippers, crimping tools, heat gun (for terminals).
- Electrical Components: MC4 connectors, DC isolators, SPDs, and appropriately gauged wires (e.g., 10 AWG for AC, 12 AWG for PV).
- Safety Gear: Insulated gloves, voltage tester.
