What batteries are compatible with pure sine wave inverters?

These inverters are compatible with most common battery types, including AGM, GEL, flooded lead-acid, and LiFePO4 batteries, as long as the battery system voltage matches the inverter (12.8V).

Can it power my coffee maker, fridge, kettle, microwave, etc.?

It can power many appliances like coffee makers, fridges, and kettles, as long as their running and startup wattage are within the inverter’s continuous and peak ratings. Appliance power varies by model - please CHECK the label before use.

Does it come with a remote?

Yes. It includes a wired LCD remote control, allowing you to monitor power status from your living space without needing to check the inverter in the electrical compartment.

Can it be used in a boat?

Yes. With built-in GFCI protection, the inverter is suitable for boats and marine environments. For safe and proper operation, ensure the inverter is correctly grounded according to marine electrical standards.

What size battery do I need for the 2000W inverter?

For a 2000W 12V inverter, at least two 12.8V 100Ah batteries are recommended. More batteries may be needed for high-current appliances or longer runtime.
