For a 3000W inverter, the power required by the battery depends on how long you need power and the efficiency of the inverter. To determine the appropriate battery power, you need to consider the power consumption of the converter and how long you want it to run. For example, if your 3000W inverter operates at 12V, it would require approximately 250 amps of current (3000W / 12V = 250A). Therefore, for a battery setup, you would need a battery or battery bank that can provide sufficient current and capacity to handle the load.
This means using large capacity batteries or multiple batteries connected in parallel to meet current demand and ensure reliable operation.
A 150 Ah battery is generally suitable for use with an inverter operating at a lower power level or for shorter durations. For example, if you are using an inverter rated at 1500W and your battery is rated at 150Ah, the battery should be able to support the inverter for a while, assuming a conversion efficiency of appropriate power.
However, for longer use or higher power demands, you may need a larger battery bank or combination of batteries to provide the necessary capacity and ensure extended operation.
For a 3000W inverter, selecting the right battery involves ensuring that the battery can handle the high current draw required. Ideally, you would use a battery with a capacity of at least 300 Ah at 12 V to provide a reasonable balance between power supply and run time. Alternatively, using multiple batteries in parallel to pool their amp hours can also meet power needs.
Make sure the battery or battery bank you choose can handle the high current draw and has enough capacity to meet the converter’s needs over the desired period.
A 200 Ah battery can be combined with an inverter depending on power requirements and desired operating time. For example, a 2000 W converter would draw approximately 167 amps at 12 V (2000 W / 12 V = 167 A). A 200 Ah battery, if fully charged and allowing for some inefficiencies, can power such a converter for a short time.
However, for longer use or higher efficiency, a larger battery bank may be required to ensure reliable power and longer run time.
For a 2000 W converter, the battery must be chosen according to the power consumption of the converter and the desired autonomy. A 12V battery with a capacity of at least 200Ah is recommended to efficiently manage current consumption and provide enough power for extended use. A larger capacity battery or multiple batteries connected in parallel can help meet power requirements and ensure stable operation of the converter.
