Suunny SD-large power PV charging controller
Detailed Description

SUUNNY solar charge controller, SOLAR CONTROLLER,battery controller, controller, charger controller

Performance feature:
1. Microcomputer chip control, parameter of charging, discharging and temperature compensation coefficient can be programmed and set randomly, which can be applied to special requirements of different surrounding
2. LCD dot matrix modular displays Chinese and English operation menu and the user can switch and select
3. LED indication lamp displays every photovoltaic charging status and load on/off status
4. Operating by 9 light touch buttons
5. Control circuit is completely separated from main circuit with high anti-jamming ability
6. Circuit1-18 input control of Solar battery
7. Displaying more than ten parameters such as storage battery voltage, load current, total photovoltaic current, photovoltaic current of each circuit, storage battery temperature, cumulative photovoltaic generation Ah and cumulative load Ah etc
8. Past data statistic display: times of over-charging, over-discharging, overload and short circuit
9. Such parameter as generator start/stop voltage, secondary load on/off voltage, wind turbine unloading/recovery voltage and light sensitive switch voltage of street lamp can be programmed and set
10. The user can respectively set load on/off situation of storage battery over-charging and over-discharging protection
11. Secondary electricity control ability, namely control on main load and secondary load at different voltage v alue of storage battery
12. Return difference control function in the charging voltage detector of various circuits, which can prevent switch from resonance
13. Protective function: alarm and protective function such as storage battery over-charging, over-discharging, output overload, short circuit, surge, reverse connection or short circuit on solar battery, reverse connection on storage battery and night anti-charging prevention
14. It can be equipped with RS232/485 joint for remote surveillance and control PC monitoring software can determine real time data, display alarm information, modify control parameter, read past data such as highest and lowest voltage of storage battery, accumulated photovoltaic power generation amount and accumulated load power consumption of every day in 30 days
15. Parameter setting has code protection and the user can modify the code
16. Warning: protection alarm of over-voltage, under-voltage, over-load and short circuit
17. Multi-circuit passive output alarm or control joint: storage battery over-charging and over-discharging, control on diesel engine startup, load shutting-down, controller failure other spare alarm joints can be selected by the user such as flood alarm
18. There are working patterns of gradual stage current restriction pattern, PWM working pattern, button working pattern, light open and light break pattern, light open and time break pattern, clock control pattern, light open and time break and light before dawn pattern, of which the former three patterns are for general load situation the latter four patterns are for street lamp load situation. All delay length and timing clock can be set
19. The user can set the parameter including: balanced charging voltage, float charging voltage, absorption voltage, startup voltage, dynamic pressure stabilization coefficient, static pressure stabilization coefficient, balanced charging time and absorption time.
20. Real time clock function without electricity breaking can display and set the clock
21. Lightning protection: lightning protection devices can be installed at different level according to system requirement
22. Temperature compensation function
23. Flexible combination: stand-alone system, as well as wind/solar hybrid System and combination system of control and invert.
