1. With the advanced dual-peak or multi-peak tracking technology, when the solar panel is shadowed or part of the panel fails resulting in multiple peaks on the I-V curve, the controller is still able to accurately track the maximum power point.
2. A built-in maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems, and raise the charging efficiency by 15% to 20% compared with the conventional PWM method.
3. A combination of multiple tracking algorithms enables accurate tracking of the optimum working point on the I-V curve in an extremely short time.
4. The product boasts an optimum MPPT tracking efficiency of up to 99.9%.
5. Advanced digital power supply technologies raise the circuit's energy conversion efficiency to as high as 98%.
6. Different charging program options including those for gel batteries, sealed batteries and open batteries, customized ones, etc. are available.
7. The controller features a limited current charging mode. When the solar panel power exceeds a certain level and the charging current is larger than the rated current, the controller will automatically lower the charging power and bring the charging current to the rated level.
8. Instantaneous large current startup of capacitive loads is supported.
9. Automatic recognition of battery voltage is supported.
10. LED fault indicators and an LCD screen which can display abnormality information help users to quickly identify system faults.
11. Historical data storage function is available, and data can be stored for up to a year.
12. The controller is equipped with an LCD screen with which users can not only check device operating data and statuses, but also modify controller parameters.
13. The controller supports standard Modbus protocol, fulfilling the communication needs of various occasions.
14. All communications are electrically isolated, so users can rest assured in usage.
15. The controller employs a built-in over-temperature protection mechanism. When temperature surpasses the set value, the charging current will decline in linear proportion to the temperature and discharging will be halted so as to curb the temperature rise of the controller, effectively keeping the controller from being damaged by overheat.
16. With the help of an external battery voltage sampling function, battery voltage sampling is exempted from the effect of line loss, making control more precise.
17. Featuring a temperature compensation function, the controller can automatically adjust charging and discharging parameters in order to extend the battery's service life.
18. The controller also features a battery over-temperature protection function, and when the external battery temperature exceeds the set value, charging and discharging will be shut off so as to protect components from being damaged by overheat.
19. TVS lighting protectionProtection Functions:1. Waterproof
Waterproof level: IP32 2. Input power limiting protection
When the solar panel power exceeds the rated power, the controller will limit the charging power under the rated power so as to prevent excessively large currents from damaging the controller and enter into current-limited charging. 3. Battery reverse connection protection
If the battery is reversely connected, the system will simply not operate so as to protect the controller from being burned. 4. Photovoltaic input side too high voltage protection
If the voltage on the photovoltaic array input side is too high, the controller will automatically cut off photovoltaic input. 5. Photovoltaic input side short-circuit protection
If the photovoltaic input side gets short-circuited, the controller will halt charging, and when the short circuit issue gets cleared, charging will automatically resume. 6. Photovoltaic input reverse-connection protection
When the photovoltaic array is reversely connected, the controller will not break down, and when the connection problem gets solved, normal operation will resume. 7. Load overpower protection
When the load power exceeds the rated value, the load will cut off output after a time delay. 8. Load short-circuit protection
When the load is short-circuited, the controller can implement protection in a quick and timely manner, and will try to switch on the load again after a time delay. This protection can be carried out up to 5 times a day. Users can also manually address the short circuit problem when finding the load is short-circuited via the abnormality codes on the system data analysis page. 9. Reverse charging protection at night
This protection function can effectively prevent the battery from discharging through the solar panel at night.10. TVS lighting protection.11. Over-temperature protection
When the controller temperature exceeds the set value, it will decrease the charging power or halt charging. See the following diagram:
When the ambient temperature rises higher than the set value, the controller will stop charging and discharging.Application:
