The Fibramérica FAB-QYGD-SECM Series comprises MPPT solar charge controllers for photovoltaic battery-charging systems. The controllers use maximum power point tracking to regulate charging from solar panels, and include an LCD display for operating information and configuration.
The series is listed with 10A, 20A, 30A and 40A current ratings, depending on the model. The manufacturer’s catalog describes three-stage charging, support for several battery chemistries and built-in electrical protection functions. Optional USB charging and communication interfaces depend on the selected configuration.
Refer to the technical specifications to select the appropriate controller according to the photovoltaic array and battery system. Voltage and power ratings must be checked for the specific variant before ordering.
