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.

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.
