Expected runtime
Formula: usable energy divided by load. Figures are estimates and drop 10-15% in high heat or at high discharge current.
| Load | Expected runtime |
|---|---|
| 0.5 kW | 32.4 h |
| 1 kW | 16.2 h |
| 2 kW | 8.1 h |
| 3 kW | 5.4 h |
| 5 kW | 3.2 h |
Advantages
- Up to 90% of nameplate capacity is usable
- Several times the cycle life of lead acid
- Lower weight and volume per kWh
- Built-in BMS for protection and cell balancing
Points to consider
- Higher upfront cost than lead acid
- Requires an inverter with a lithium charge profile or correct manual settings
- The BMS may derate charge current in extreme heat
Installation and usage considerations
Mount in shade with airflow around the enclosure, set charge and cut-off voltages to the manufacturer's figures, and never mix lithium packs of different ages or capacities on the same bus.
Use cable sized for the current with a short run between bank and inverter, plus a breaker or fuse on the positive terminal. Thin cable and long runs are the number-one cause of poor performance wrongly blamed on the battery.
How to pick the right option
Start from daily kWh and the hours you need, then divide by allowed depth of discharge (0.9 lithium, 0.5 gel) to get required nameplate capacity.
Fix the system voltage from your inverter, then compare options on price per usable kWh rather than price per unit.
