Calculate how much energy is lost due to inverter inefficiency and find the real usable AC power or kWh output from a DC source. Formula: AC Output = DC Input × (Efficiency/100) × (1 - Margin/100). Introduction to Solar. . A standard 12V 100 Amp-hour (Ah) deep cycle battery will run a moderate 200-watt (W) load for approximately 2. If you were to push it to the full 500W capacity of the inverter, that runtime could drop dramatically to just over one hour. So less energy is output than is input. Key factors include battery type (lithium vs. lead-acid), ambient temperature, and energy management. .

In short, 12v battery will last between 40 minutes to 7 hours running a 500-watt inverter. If you were to push it to the full 500W capacity of the inverter, that runtime could drop dramatically to just over one hour. The exact duration depends entirely on two. . As a simple rule, to calculate how long a 12v deep-cycle battery will last with an inverter multiply battery amp-hours (Ah) by 12 to find watt-hours, and divide by the load watts to find run time hours. Finally, multiply run time hours by 95% to account for inverter losses. 4 hours (100Ah × 12V × 0.
