Inverters for RVs are typically12 or less commonly, 24V. Choose from brands including Victron and Latronics. We offer pure sine wave inverters and inverter chargers which can recharge your house battery from an AC source such as 240V shore power or a generator.
Pro tip: you also need to consider your battery bank size, especially with lead based chemistries (AGM, Gel, Lead Carbon) because voltage drops under heavy load. This is less of an issue with lithium.
