1. Introduction
The SBC-6108/6112/6120 PV Charge Controller is designed for use with all types of 12V
photovoltaic(PV) panels/systems and different types of 12V batteries, such as wet or sealed lead
acid, lead calcium, lead antimony battery.
Numerous features are provided to maximize the performance of the system:
●
Electronic Blocking (To protect against reverse polarity connection of PV panel and block
current from battery to PV Panel when voltage of Battery is higher than PV panel),
●
Suitable for PV panels with Open Circuit Voltage from 17 to 23V,
●
Rated charging/load current 8A (SBC-6108)/ 12A(SBC-6112) / 20A(SBC-6120),
●
PWM Charging,
●
Build-In Microprocessor for PV charge control to maximize the charging efficiency,
●
Overcharge and Over-discharge Protection,
●
3-stage Charge Control(Bulk, Absorption & Float) to allow battery be left unattended for long
period ,
●
Over Temperature Protection,
●
Night Light Mode 10 selections
●
Short-Circuit Protection at load terminal & Battery Reverse Polarity Protection at Battery
Connection Terminal,
●
Tri-Color LED indication of system and battery conditions,
●
Optional
Temperature Sensor for compensated battery charging,
●
Optional
Remote Signal Terminal.
