Product Description
MPPT 15A 12V/24V Solar Controller suit for Li-ion battery Sm1575-Li
Descriction :
Smart-MPPT Li series intelligent MPPT solar controller is programmable and especially for solar light system. The charging efficiency is about 20% higher than the traditional PWM controller, which can make the cost of the whole system much lower.
It comes with a number of outstanding features, such as:
1) Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99%
2) Full digital technology, high charge conversion efficiency up to 96%
3) 5 stages time can be adjusted
4) Can read parameters and running status
5) When BMS power off because of LVD, it can activate the system automatically
6) Charging target voltage and charging recovery voltage can be set
7) Day/Night threshold can adjust automatically
8) Remote Unit to configure, with LED display IP67, Strong and durable aluminum case
9) Full automatic electronic protect function

*1.Controller can protect itself, but loads might be damaged.
*2.Battery must be protected by fuse, otherwise battery will be damaged. *3.The PV panel voltage should not exceed 60V for a long time.
*4. Please refer to "11.Technical Data" to get the max v!oltage of battery.
Warning: The combination of different error conditions may cause damage to the controller. Always remove the error before you continue connecting the controller.
LED Display Explanation
| LED | Status | Function |
| Green LED | Slow flash(0.5s/2s) | Battery connected, Daytime detected |
| Flash(0.5s on/0.5S off) | Charging,reach the target voltage | |
| Fast flash(0.1S/0.1S) | MPPT Charging | |
| on | Battery connected, night detected | |
| Red LED | Off | No fault detected |
| on | Low voltage protection | |
| Slow flash(1s /1s) | Over current or short circuit protection | |
| Flashing (0.5s/0.5s) | Over temperature protection | |
| Fast flash(0.1s/0.1s) | Over voltage protection | |
| Red Green | Both off | No connection to battery |
| Both on 1s | Start up Self test |
Faults & Alarms
| Fault | Status | Reason | Remedy |
| Loads are not powered | Low volt. protection | Battery capacity is low | Load will be reconnected when battery is recharged |
| Over current, short circuit protection | Loads are over current or short circuit | Switch off all loads, remove short circuit, load will be reconnected after 1 minute automatically | |
| Over temp. protection | Controller temp. is too high | Load reconnects after temp. reduces | |
| High voltage at battery terminal | Over voltage protection | High battery voltage >("CVT" + 0.2V) | Check if other sources overcharge the battery. If not,controller is damaged |
| Battery wires or battery fuse damaged, battery has high resistance . | Check battery wires, fuse and battery. | ||
| Battery is empty after a short time | Low voltage protection | Battery has low capacity | Change battery |
| Battery can't be charged | Green LED is on | PV panel fault or reverse connection | Check panels and connection wires |
Day/Night Threshold, Day/Night Delay
The controller recognizes day and night based on the solar array open circuit voltage. This day/night threshold can be modified according to local light conditions and the solar array used. Day/Night threshold setting range: 3.0~20.0V.
In the evening, when the solar array open circuit voltage reaches the setting day/night threshold, you can adjust the day/night delay time to make the load turn on a little later.
Day/Night delay time setting range: 0~30min.
Day/Night threshold voltage should be set around 0.22 times of open circuit voltage.
2.Day/Night threshold voltage of load disconnect is 1V higher than the setting data, means the load will disconnect when the solar voltage at 4.0~21.0V. 3.The controller has an automatic day/night threshold adjustment function. If the lowest voltage of solar array is higher than the setting day/night threshold, the load has no output in first night, 24 hours later the controller can automatically adjust the day/night threshold to meet the requirements of lighting at night.
