Hi everyone,
I'm setting up a solar power system and I wanted to share the details to get your opinions and any additional advice you might have. Here's an overview of my setup and the recommendations I received from an AI assistant.
Note: The manuals for the inverter and the battery are here: Manuals
### Description:
### System Components:
1. **Inverter**: Easun Power 3.2KW Off-Grid Hybrid Inverter
2. **PV Panels**: 9 x 100W, 12V panels
3. **Battery**: Easun 100ah 24V
4. **Cables**:
- **Battery to Inverter**: 2AWG cables
- **PV Panels to Inverter**: 12AWG cables
5. **Connectors**:
- **MC4 Connectors** for PV connections
6. **Circuit Breakers**:
- **125A double-pole DC circuit breaker** for battery protection
- **15A DC circuit breaker** for PV connection
- **50A AC breaker** for AC input power source
### Configuration Recommendations:
#### PV Panels:
- **Series Connection**: Connect all 9 panels in series.
- **Voltage**: 9 panels x 18V = 162V (within the MPPT range of 30V-500V).
- **Current**: ~6A (within the maximum input current of 15A).
#### Battery Connection:
- **Cables**: Use 2AWG cables for battery-to-inverter connection.
- **Connectors**: Use 2AWG copper ring terminals (3/8") for secure connections.
- **Installation**:
1. Strip about 1 inch of insulation from the cable ends.
2. Crimp the ring terminals onto the cable ends using a crimping tool.
3. Cover the connections with heat shrink tubing for protection.
#### PV Connection:
- **Cables**: Use 12AWG cables for connecting PV panels.
- **MC4 Connectors**: Use for secure, weatherproof connections.
- **Installation**:
1. Strip about 10-12mm of insulation from the cable ends.
2. Crimp the MC4 connectors onto the cable ends.
3. Connect the male and female MC4 connectors between the panels and the inverter.
### Safety Precautions:
- **Overcurrent Protection**: Use appropriate circuit breakers to protect your system.
- **Proper Wiring**: Follow the manual’s instructions and ensure all connections are secure.
- **Qualified Personnel**: Ensure installation is performed by qualified individuals.
- **Correct Sizing**: Use cables and connectors that match the system’s current and voltage ratings.
### Additional Context:
I've included the detailed steps and recommendations received from the AI assistant to ensure a safe and efficient setup. I'm particularly interested in hearing if there's anything I might have missed or any improvements that can be made to enhance the system's performance and safety.
Thank you for your time and advice!
### Summary:
- **Inverter**: Easun Power 3.2KW Off-Grid Hybrid Inverter
- **PV Panels**: 9 x 100W, 12V connected in series
- **Battery Cables**: 2AWG with copper ring terminals (3/8”)
- **MC4 Connectors**: For PV connections
- **Circuit Breakers**: 125A DC for battery, 15A DC for PV, 50A AC for input
Looking forward to your feedback and any additional suggestions!
