How Long Can an Inverter Last on Battery Power? Leave a comment
One of the first things people ask after installing an inverter is, “How long will it last before it goes off?”
This blog will explain:
-
How to calculate backup time using battery capacity (Ah) and load size (watts)
-
Factors affecting runtime: battery health, inverter efficiency, type of load
-
Real-life examples:
-
1.5kVA inverter with 2x200Ah batteries — 6 to 10 hours backup
-
3.5kVA inverter with 4x220Ah batteries — 10 to 18 hours backup
-
-
Tips to extend backup time (use LED bulbs, unplug heavy devices, regular maintenance)
