Introduction:
EP48-100/200/300 is a kind of intellgent PV controller designed for large scale off-grid PV generating system. With the function of managing charging or discharging it can control multi-channel solar cells matrix. According to the trend of battery pack it can automatically control the connection or snap in turn for solar cell matrix, in which using solar cells effectively and guranting the safety and reliability for battery pack operation.
Performance
1. Total cathode control mode and multi-channel solar panel array input control are adopted.
2. Adopting 32-bit processor. High acurracy in controlling voltage.
3. Backlash function detecting each-channel charging voltage to avoid oscillation of switch.
4. Complete isolation between control circuit and main circuit for extreme anti-jamming capability.
5. Multiple parallel is available.
6. Adopting touch screen, Chinese and English menu display, alarm display function.
7. Historical record and password protection function.
8. Electricity consumption AH accumulative function, including PV generating capacity, load consuption and batteries power.
9. All-round protection functions against charging overvoltage, overtemperature, battery undervoltage, wrong connection, overload, shortcircuit, pannels wrong connection, reverse charging in night.
10. Supporting RS485/232 communication for remote monitor.
11. Temperature compensation and environmental temperature/humidity monitoring function.
