CARLO GAVAZZI SBCLC 10A

The CARLO GAVAZZI SBCLC 10A is a solar battery charger and a load/light control device with an advanced design using a microcontroller for digital accuracy and fully automatic operation. It can be used for 12V, 24V, and 48V systems and can be operated at three major functions including solar charging, load control, and lighting control.

The PWM battery charging has been optimized for longer battery life and the state-of-the-art auto detector of day and night has been precisely applied to log the different length of night hours for lighting control no matter where and when (the North or the South, winter or summer) SunBright is installed.

Electrical Data

SunBright is a solar battery

charger and a load/light control

device with an advanced design

using a microcontroller for

digital accuracy and fully

automatic operation. Each model

unit can be used for 12V, 24V and

48V system and can be operated

at three major functions including

solar charging, load control and

lighting control.

The PWM battery charging has

been optimized for longer

battery life and the state-of-

the-art auto detector of day

and night has been precisely

applied to log the different

length of night hours for lighting

control no matter where and

when (the North or the South,

winter or summer) SunBright is

installed.

Note:

• The device prevents reverse current leakage at night, so a

blocking diode is not required in the system.

• The terminals will accept a maximum wire size of AWG#10

(up to 5.2mm2). (Some #10 spade connectors may not fit in

this terminal.)

• Tighten each terminal screw maximum to 20x0.1130Nm

(20inch-pounds) of torque.

• It is designed to regulate power from a PV array. However

other generators can be connected directly to the battery,

with no effect on this device.

• A battery below 10V may not start the microcontroller

properly. Make sure the battery is charged before installing

the system.

Minimum Clearance

Install the device vertically and leave at least 5cm all around

in order to improve cooling.

LED status

Charge Status LED

Blinking Green: Charging is in the state of Bulk or Absorption.

Fixed Green: Charging is in the state of Float.

Fixed Orange: Charging in the state of Equalization.

Fixed Red: Charging in the state of fault: Over Current.

Blinking Red: Charging in the state of fault: Over Temp.

Load Status LED

Blinking Green: If the battery charge state falls below the disconnect setpoint voltage (Initial

setting: 11.1V for 12V system, 22.2V for 24V system and 44.4V for 48V system) lasting for six

minutes, the green LED will blink to be ready for load disconnection.

Fixed Orange: After six minutes of battery voltage under setpoint, the orange LED will lit to

show the low voltage disconnection for loads.

Blinking Orange: When the battery voltage goes over to above the reconnect setpoint value

(Initial setting: 12.6V for 12V system, 25.2V for 24V system and 50.4V for 48V system), the

orange LED will blink to be ready for reconnection for six minutes.

Fixed Green: Battery discharges to DC load after six minutes of reconnection process, the

green LED will be lit to show battery successfully discharges to DC load.

Fixed Red: Load control in fault: Load Over Current.

Blinking Red: Load control in fault: Over Temperature.

LIGHT TEST Button

Press the LIGHT TEST button to enter the testing

mode to check if the Lighting Control Switch has

been correctly set in order to control the lights

based on desired timer.

It counts 24 hours a day as 24 seconds so 1 hour is equal to 1

second and 12 seconds for day time and 12 seconds for night time.

Battery Voltage Sensor (BVS)

BVS

Battery Temperature Sensor (BTS)

A sensor next to the remote panel is used for

temperature compensated battery charging.

As the battery gets warmer, the gassing increases. As

the battery gets colder, it becomes more resistant to

charging. Depending on how much the battery

temperature varies, it may be important to adjust the

charging for temperature changes.

Features

Solar Overload Enhanced radiation or

“edge of cloud effect”

conditions can generate

more current than the

controller’s rating. The

device will reduce this

overload up to 130% of

rated current by regulating

the current to safe level. If

the current from the solar

array exceeds 150%, the
