The Pure Sine Wave Inverter 300–500W is an ideal long-term backup power solution suitable for both home and office appliances. It serves not only as an inverter but also incorporates a robust intelligent charger. Providing pure sine wave power to various loads, it can also function as a UPS for computers.
Product Description
The Pure Sine Wave Inverter 300-500W features a tower design and utilizes DSP digital control technology to deliver pure sine wave output. It accommodates a wide range of loads, including resistive, inductive, rectified loads, and motors. Employing pulse-by-pulse technology enhances its ability to withstand load shocks. With a maximum charge current of 15A. Furthermore, it boasts protection features against short circuits, overload, and low batteries, ensuring safe operation. With an intelligent long backup capability of up to 10 hours (depending on the battery bank and loads), it can be paired with generators, with the option to configure the compatibility between the inverter and generator. Moreover, when combined with an EAST charge controller, it can serve as an off-grid solar inverter.
