How long does it take for the inverter battery to be fully discharged

A 12V battery's runtime with an inverter depends on the battery capacity (Ah), the inverter's efficiency, and the power load. On average, a 100Ah deep-cycle battery running a 300W load can last about 3 to 4 hours before reaching a 50% depth of discharge (DOD). Remember, battery health affects these times, and aging. . The table below provides a simplified runtime estimate for a 12V battery under two scenarios: when the inverter is running at full rated load and when it's operating with no load (assuming 5% self-consumption). Finally, multiply run time hours by 95% to account for inverter losses. Through detailed analysis, we hope. . [PDF]
