Features of the 12V or 24V 20A MPPT Solar Charge
Controller for Flooded, SLA, AGM, Gel, and Lead Acid Battery Packs:
crest or multi crest tracing technique design, used when the solar panel is
under shadow or part of the solar panel is damaged. Multi crest will turn up in
I-V curve, the controller can still trace the Max Power point.
maximum power point tracking algorithm which could promote energy utilization
efficiency of PV system. The charging efficiency is 15%-20% higher than PWM
algorithm to track the best working point of the I-V curve promptly and
accurately, the MPPT efficiency could reach 99.9%.
digital power supply technology which makes the energy conversion efficiency
reach up to 97%.
charging stages: MPPT – equalizing charge – boost voltage charge – floating
current-limiting charging mode, when the power of the solar panel is oversized,
the controller will lower the charging power automatically, which enables the
system to work under the rated charging current.
code indication to help users confirm the system fault.
load control methods to improve the system’s flexibility.
compensation function to adjust the charge and discharge parameters
automatically, which could improve the life of the battery.
system protection functions, including over-charge, over-discharge, over-load,
over-heat, and battery reversing connection protection.
