Backup time on this battery
The PR LFP Battery 51.2V 400Ah stores 20.48 kWh (51.2 V × 400 Ah). Through an inverter about 16.6 kWh reaches your appliances (81% of the stored energy, the same allowance our battery calculator uses), so backup time is about 16589 Wh ÷ the load:
| Load running | Backup time |
|---|---|
| 300 W | 2 days |
| 500 W | 33 h 11 min |
| 1.0 kW | 16 h 35 min |
| 1.5 kW | 11 h 4 min |
| 2.0 kW | 8 h 18 min |
| 3.0 kW | 5 h 32 min |
| 5.0 kW | 3 h 19 min |
यह बैटरी 20.48 kWh स्टोर करती है। इन्वर्टर से लगभग 16.6 kWh उपकरणों तक पहुँचती है, जैसे 1 kW लोड पर लगभग 16 h 35 min बैकअप।
Inverters that take this battery
This is a 48 V class battery (51.2 V nominal), so it pairs with hybrid inverters built for a 48 V DC battery: PR Hybrid Inverter 6.2kW, PR Hybrid Inverter 8.2kW, PR Hybrid Inverter 11kW, PR Hybrid Inverter 12kW. Check the inverter battery setting is on LiFePO4 / lithium before first charge.
Solar to recharge it in a day
In most of India 1 kW of panels makes about 4 units (kWh) on a clear day, so this battery needs about 5.1 kW of panels to refill from empty in one sunny day. Panels come in whole units, so in practice that is 10 panels of 550 W (5.5 kW). Solar running your daytime load at the same time needs more panels on top.
