• 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.
• PV Panel 12V, 20A System, LCD & LED Display
• The MCU ( Microprocessor controller) is programmed with3 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 *Equalization* 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 thebattery 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 conditionof PV data for efficiency and actual capacity of your system.
• *Equalization* Charging is only for Wet type lead acid battery; automatically cycles once a month for 2 hours. Equalization Charging can be de-activated or re-activated manually.
• DC Output (for Small DC Load)
• 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.

Features:

• User adjustable charging voltages between 12.0 to 16.5V.
