Compact, High-Efficiency Inverter for Mobile Energy Systems – OEM/ODM Available

Product Description:

ZI32A-1K5W is a compact 1500W bidirectional inverter integrating battery charging and discharging functions into a single power conversion unit. Designed with advanced soft-switching resonant technology, it delivers high-efficiency energy conversion, reduces power loss, and provides a reliable power solution for mobile and off-grid energy applications.

Supporting a wide range of battery chemistries, including ternary lithium, LiFePO₄, lead-acid, and sodium-ion batteries, ZI32A-1K5W offers excellent compatibility and flexibility for different energy storage systems. With its compact structure, bidirectional power flow capability, and RS485 communication interface, it is well suited for RVs, portable outdoor power stations, and emergency backup power systems.

The inverter provides a pure sine wave AC output with THD below 5%, ensuring clean and stable power for a wide range of household appliances, electronic devices, and commercial equipment. The inverter conversion efficiency exceeds 90%, while the integrated charging function supports up to 300W charging power, improving overall energy utilization and system performance.

For reliable operation under various load conditions, ZI32A-1K5W adopts an intelligent thermal management system with a built-in cooling fan and high-performance heat sink. The optimized design provides effective heat dissipation while maintaining low operating noise.

Safety and durability are enhanced through multiple protection functions, including over-voltage, under-voltage, over-current, overload, short-circuit, and over-temperature protection. Soft-start technology is applied to both charging and discharging processes to reduce inrush current and voltage impact, helping extend equipment service life. The isolated electrical design improves anti-interference capability and enhances operational safety for both users and connected devices.
