CN2450-S model is based on single DSP chip high-speed microprocessor design or industrial grade solar control all digital inverter, with a more complete battery charge and discharge control, can output pure sine wave power, can meet the remote areas without electrical area of telecommunications, broadcasting television and household electricity requirements, with a high degree of automation, stable performance, complete functions, perfect protection, easier maintenance and so on. The products in the whole input and output control and power conversion to achieve a fully digital design, and a good solution to the circuit design analog and weak anti-interference ability of machines, control accuracy, power consumption, product line shortcomings and poor.
Second, the main functions and features:
1, the use of high-speed single DSP chip control, more stable performance, large capacity FLASH memory technology, products can be online and no-cost technology upgrades.
2, AC isolation and high-speed PI regulator feedback control, accurate and stable output AC voltage, load and unload more reliable.
3, the whole realization of all-digital, automated, battery charge and discharge using intelligent fuzzy display technology, precise charge and discharge control, display and intuitive and easy to understand;
4, low-power design of more highlights the importance of solar energy applications;
5, more complete protection; with over charge, over discharge and over-voltage protection, overload and short circuit protection, reverse charge protection, battery open circuit protection, thermal protection (parental);
