Precautions

1. Before using the charge/load controller, read all the instructions and cautionary markings on the

charge/load controller, the batteries and the photovoltaic panels.

2. Do not attempt to repair the controller. Incorrect re-assembly may result in a risk of electric shock or
fire.

3. To reduce risk of electric shock, disconnect all wiring before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk. PV panels produce power when exposed to light – cover
them with opaque material before servicing.

4. Working in Vicinity of a Lead Acid Battery is dangerous. Batteries generate EXPLOSIVE gases during
normal operation. Provide ventilation to outdoors from the highest point of the battery compartment.

5. This charge/load controller is intended to be used with a battery supply of 12 VDC nominal voltage.

6. Be extra cautious to reduce the possibility of dropping a metal tool onto batteries. It might spark or

short-circuit batteries or other electrical parts that may cause explosion. Cover wrench handles with
plastic tape or vinyl dip coating material.

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.
