Features of SR-ML4860
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.
