1.1 Product overview and characteristics
CEP series is a new type of mixed solar energy storage inverting & control all-in-one machine integrating
solar energy storage & municipal power charge storage and AC sine wave output. It adopts DSP control and
advanced control algorithm to achieve characteristics of high response speed, high reliability and high
industrial standard. There are four charge modes namely only solar power, mains power priority, solar power
priority, mains power & solar power; and two optional output modes, namely inverting and mains power to
meet different application needs.
The solar charging module applies the latest optimized MPPT technology to quickly track the maximum
power point of the PV array in any environment and obtain the maximum energy of the solar panel in real
time.
Through an advanced control algorithm, the AC-DC charging module realizes fully digital voltage and
current double closed loop control, with high control precision in a small volume. Wide AC voltage input
range and complete input/output protections are designed for stable and reliable battery charging and
protection.
Based on full-digital intelligent design, the DC-AC inverter module employs advanced SPWM technology
and outputs pure sine wave to convert DC into AC. It is ideal for AC loads such as household appliances,
power tools, industrial equipment, and electronic audio and video equipment. The product comes with a
segment LCD design which allows real-time display of the operating data and status of the system.
Comprehensive electronic protections keep the entire system safer and more stable.
