High Performance Mppt Solar Charge Controller 20 Amp Support Data Storage

Features of SRML2420

1. Can be used in all kinds of bad environment with Aluminum frame.
2. Double crest or multi crest tracing technique design, when the solar panel is under shadow or part of the solar panel is damaged, multi crest will turn up in I-V curve, and the controller can still trace the Max. Power Point.
3. Built-in maximum power point tracking algorithm which could promote energy utilization efficiency of pv system. The charging efficiency is 15%~20% higher than PWM mode.
4. Adopting sorts of tracking algorithm to track the best working point of I-V curve promptly and accurately within 15 seconds, the MPPT efficiency could reach to 99.9%.
5. The use of advanced digital power technology, circuit energy conversion efficiency is as high as 96%
6. Four stage charging order mode: MPPT-equalizing charging-boost charging-float charging.
7. With current-limiting charging mode, when the power of solar panel is over-sized and charging current exceeds the rated current, the controller will lower the charging power, which enables the system to work under the rated charging current.
9. The controller can realize networking operation by the link with telecommunication cable.
10. Have the fault code indication; it helps users confirm the system falt
11. 12V/24V/36V/48V auto identified.
12. Support data storage, the storage span can reach 5 years.
13. It can connect with LCD screen monitoring and the controller parameters are amendable.
14. Built-in temperature sensor, when the temperature exceeds the set value, the charging current will lower down followed by the decrease of temperature, so as to control the controller’s temperature rise.
15. With temperature compensation function to adjust the charge and discharge parameters automatically, which can improve battery service life.
16. Various system protection functions. Including over-charge, over-discharge, over-load, over-heat, the battery reverses connection protection and so on.
17. TVS lighting protection.

Parameter of SR-MT45A/60A

Application
Solar Station System
Solar power station systems are typically used for regional centralized power supply, such as village, island, fields monitoring and so on. Also the power level range is between kilowatts to hundreds kilowatts.

Solar Home System
Solar home system are typically used for home photovoltaic power generation system, to solve electricity demand of none power or unstable power region. Also the power level rage is between hundred watts to kilowatts.

Solar RVs/Vessels System
Solar RVs/Vessels system are typically used for reducing the RVs and the vessels electricity cost, by setting up solar system to assist gasoline/diesel power generator.

Solar Street lights System
Solar Street lights System are typically used for street lightning of cities, villages, the intelligent streetlight system will remote monitoring all street lamps to reduce the operation and maintenance costs of system.

Hybrid Energy System
The Hybrid energy system contains solar, wind, diesel and city electricity energy system. The system will meet the load demand of electricity in villages, islands, and telecom stations to reduce the system cost and improve the replenishment ratio of system.
