⚡ Inverter Guide
The number of batteries required depends on the inverter size and the battery BMS rating.
| Inverter Size | Recommended Battery Setup With Current Package |
|---|---|
| 150W – 1200W inverter | 1x 100Ah batteries with 100A BMS |
| 150W – 2400W inverter | 2x 100Ah batteries with 100A BMS (200Ah 200A BMS Total) |
| 150W – 4800W inverter | 4x 100Ah batteries with 100A BMS (400Ah 400A BMS Total) |
Batteries take up a lot of space, it is recommended for larger inverters to select a bigger battery and BMS combo
Always confirm inverter load, surge draw, cable sizing, fuse protection, BMS rating, and installation requirements before use.
❓ What Happens If the Discharge Rating Is Exceeded?
The Thumper lithium battery is protected internally by a Battery Management System. The BMS helps protect the battery against overcharge, low voltage, and excessive discharge drain.
For example, if a 3000W inverter draws approximately 250A, this twin pack package wired in parallel has a 200A BMS. If the load exceeds the 200A discharge rating, the BMS will disconnect and stop providing power to protect the battery.
Once the load is disconnected, the BMS will normally reconnect within a few seconds and the battery will be ready to use again.
⚠️ Important Usage Notes
Please confirm your required battery capacity, charging system, cable sizing, fuse protection, parallel wiring setup, series wiring setup, inverter size, BMS rating, mounting space, and system compatibility before purchase or installation.
