PCB is highly optimized, which is insulated and isolated by modularization. Full-bridge front-end circuit rectifies and provides outputs, back-end circuit transformer controlled by intelligent program. Input and output circuits are truly isolated. And model number, production date and batch are printed on the PCB for tracking.

PCB circuits are not actually insulated and isolated by modularization. Input and output are not truly isolated. Problem caused by either input or output will damage the inverter.

A. Helped by the highly optimized circuit structures, original electronic components and high-tech DSP program, full range of all our models can achieve maximum power loading by only onetime soft start. For example, 2000W inverter can onetime start directly with 2000W power loading.

Due to the limitations of hardware and software technology, the loading way is gradually increasing. For example, to start a 1000W loading, their inverter requires 200W + 300W + 500W to superimpose the loading to 1000W.
