For a 300-watt inverter, you generally need a 12-volt battery with a capacity of at least 35-40 amp-hours to ensure reliable power for an extended period. Make sure the battery is in good condition to handle the inverter’s load. If you plan on using more power-consuming devices, consider using a larger capacity battery or multiple batteries in parallel to achieve the same voltage but with higher amp-hours.

FAQs & Answers
