The SBC-7100 Series PV charge controller is designed for use with all types of photovoltaic panels and differenttypes of batteries, such as wet or sealed lead acid, lead calcium, lead antimony battery.
The MCU (Microprocessor controller) is programmed with 3 stage charging algorithms and with 0~100% PWM (Pulse Width Modulation) duty cycles to provide the fastest, optimal charging current and voltages from PV panels according to the actual state of charge and type of battery.
Bulk, Absorption, Float and Equalisation threshold charge voltage levels are user adjustable to meet specific battery manufacturer's recommendation. Hence, maximum PV charging efficiency and longer the service life span of the battery are ensured.
Electronic blocking of back current to PV and overcharging battery protection are standard. Ampere Hour logging read outs in three sets, today and last two days are shown on the LCD. This is useful to check the condition of PV data for efficiency and actual capacity of your system.
Equalisation Charging is only for wet type lead acid battery; automatically cycles once a month for 2 hours. Equalisation Charging can be de-activated or re-activated manually.
The DC output terminal has many value added night-lightmode programs, please see user manual at our website for detail descriptions. The DC output has dusk to dawn automatic on-off operations. There are 10 selectable multiple on-off programs, each with different power-on durations for various needs or lighting schedules. The battery low voltage level disconnect and reconnect settingsare user adjustable.
