Off-Grid Inverter Selection Guide
For remote islands and rural areas in Indonesia, Philippines, and other parts of Southeast Asia, off-grid solar systems are often the most practical solution.
Key Parameters to Consider
1. Inverter Capacity
- Basic lighting & phone charging: 1kW
- Home appliances + fan + TV: 3kW
- Full home + small AC: 5kW+
2. Battery Compatibility
- Ensure the inverter supports your battery type (LiFePO4 recommended)
- Check max charging current and voltage range
3. Surge Power Rating
Off-grid inverters must handle starting surges from motors, pumps, and compressors. Look for 2-3x surge capacity.
4. Protection Features
- Overload protection
- Battery over-discharge protection
- Short circuit protection
- Over-temperature protection
5. Remote Monitoring
Essential for systems in remote locations - WiFi or GSM-based monitoring allows you to check system performance without visiting the site.
