To calculate the number of batteries required for 3000 watt power inverter charger, we can use the formula-equipment continuous use time * equipment power = total power, total power / DC voltage = required amperage.

For example, if the total power of your electrical equipment is 2000 watt, the continuous use time is 3 hours, and the battery voltage is 12v, then 2000 watt*3h=6000 watt, 6000 watt/12v=500Ah, 500Ah is the required amperage . This algorithm drains the battery, and frequent draining of the battery will shorten the battery life. Under normal circumstances, we recommend a depth of discharge of 50%, that is, we recommend that you use the result obtained by this formula to divide by 50% when selecting the battery capacity.

In addition, to equip the inverter with a battery also needs to select the number of batteries according to the adaptor voltage of the inverter, and the DC output voltage of the inverter must match the voltage of the battery. If you still have questions, please contact Xindun.
