Features of the 12V or 24V 20A MPPT Solar Charge Controller for Flooded, SLA, AGM, Gel, and Lead Acid Battery Packs:
· Double 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.
· 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.
· Tracking algorithm to track the best working point of the I-V curve promptly and accurately, the MPPT efficiency could reach 99.9%.
· Advanced digital power supply technology which makes the energy conversion efficiency reach up to 97%.
· Four charging stages: MPPT – equalizing charge – boost voltage charge – floating charge.
· With 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.
· Fault code indication to help users confirm the system fault.
· Various load control methods to improve the system’s flexibility.
· Temperature compensation function to adjust the charge and discharge parameters automatically, which could improve the life of the battery.
· Various system protection functions, including over-charge, over-discharge, over-load, over-heat, and battery reversing connection protection.
