List the Devices That May Run Together
Output capacity must cover the combined running watts of devices operating at the same time. Refrigerators, pumps, and power tools may briefly require higher startup power, so check their published surge requirements.
Estimate Daily Energy
If a refrigerator averages 70 watts across its on/off cycle for 12 hours, that adds an estimated 840 Wh. Your actual equipment may differ substantially.
Add Real-World Margin
A planning margin helps account for inverter losses, aging, cold or hot temperatures, and loads running longer than expected. Avoid treating the battery’s advertised watt-hour number as completely usable energy.
- Confirm continuous AC output
- Confirm startup or surge capability
- Check usable capacity information
- Allow room for unexpected runtime
- Verify solar input voltage and connector limits
