Programmable PWM PV Charge Controller with 10 Night Light Modes

The SBC-7000 Series PV charge controller is designed for use with all types of photovoltaic panels and different types 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.
The 3 stage (Bulk, Absorption, Float) and *Equalization* charging cycles ensure complete charging cycles and maintenance of lead acid battery automatically.
Bulk and Float threshold charge voltage levels are user adjustable to meet specific battery manufacturer’s recommendation.
*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.
Hence, maximum PV charging efficiency and longer the service life span of the battery are ensured.
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.
Electronic Blocking of back current to PV and overcharging battery protection are standard.
