Inverters
Pure sine wave inverters to convert 12V DC to 120V AC for your appliances.
An inverter converts your 12V DC battery power into 120V AC household power, letting you run microwaves, coffee makers, laptops, and other AC appliances from your RV or boat house bank. Pure sine wave inverters produce clean power identical to grid electricity, while modified sine wave units produce a stepped approximation that's cheaper but can damage sensitive electronics like CPAP machines, laser printers, and variable-speed motors. For anything beyond basic resistive loads, pure sine wave is the right call.

Inverters Buyer's Guide
Sizing the inverter
List the AC appliances you'll run simultaneously and add up their wattage. Add 20% headroom and round up. A 1000W inverter handles laptops, lights, and a small TV. 2000W is the sweet spot for most RVs — it can run a microwave or coffee maker. 3000W+ is for heavy loads like air conditioners or whole-house off-grid setups.
Battery bank requirements
A 2000W inverter at full load draws ~180A from a 12V bank — that'll drain a single 100Ah battery in 30 minutes. Match inverter size to your bank capacity, and use heavy-gauge cables (typically 2/0 AWG or larger for 2000W+ inverters) to avoid voltage drop and overheating.
Pure sine wave vs modified sine wave
Pure sine wave is what you want for almost any modern setup — it's safe for all electronics and runs everything correctly. Modified sine wave is acceptable only for simple resistive loads (heaters, incandescent lights, some power tools) and should be avoided for anything sensitive.
