This solar charge controller is designed for solar DC power

supply system.

MCU and professional software are applied as

the control center to fulfill intelligent system control.

LED will indicate the working state.

It`s easy to turn on

and turn off output through manual operation.

And there are

two optional voltage modes, 12V and 24V.

Package including:

1.1PCS Solar Contorller

2.1PCS User Manual

Protection:

Overcharging protection

Can be used for all panels

Overdischarging protection

Short and Open Circuit protection

Full specification available if required

Fail Safe and cannot be damaged by accidental wiring

mistakes

Advanced design with simple plug and play technology.

No

need for complicated adjustments

Full LED status indication: State of Charge( SOC) Red- Flat

Battery: Amber- Low charge: Green- good charge: Green

Flashing- Full Charge

Features:

MCU and professional software are used as the control center

to fulfill intelligent system control, along with PWM high

efficiency charging way.

Boost, recovery and float charging

auto work for battery long- life and with temperature

compensation.

It has high accuracy over discharging control

by the discharging rate, over- discharging control voltage

modified by the battery discharging rate curve.

Our

controller has the function of self protection from

overload, outside and inside short circuit, reverse

connection, thunder and lightning, PV panel reverse current,

over charging and discharging etc.

During the short circuit

and overload protection, no any component will be damaged

and need change, including fuse.

The LED will indicate the

working state of the system in charging, overcharging power

full, power low, over- discharging, over load, out short

circuit, load on/ off and etc.

Our products meet the

industrial production standard with wide temperature running

area - 35℃ to +55℃ .

Rating:

10I: 12 Volt or 12/ 24 Volt auto work, 10 Amps ( for PV and

load)

20I: 12 Volt or 12/ 24 Volt auto work, 20 Amps ( for PV and

Equalisation voltage: 14.8Volt

High voltage disconnect( HVD) : 14.4Volt

Float voltage: 13.6Volt

Low voltage disconnect( LVD) 11.1Volt

Low voltage reconnect( LVR) : 12.6Volt

Self- consumption: 6mA maximum

Temperature compensation: - 30mV/ ℃ / 12V

Terminals: for wire sizes to 6mm2

Temperature: - 35℃ to +55℃

LED indicator:

Solar Panel LED:

Green ON when solar is charging Battery.

Green blink when the syetem over voltage

Battery LED:

Green ON when battery level in the right range

Green Slowly flashing when battery level full

Yellow ON when battery level low

RED ON when loads cut off.

LOAD LED:

RED ON when the output is on

RED slowly flashing when it`s over load

( the load amps is 1.24 times of rated current for 60

seconds, or the load amps is 1.5 times of rated current for 5

seconds.

)

RED blink when the load is short - circuit.

This controller has Light and Timer control Function

Light control: When daylight starts to occur then the light

source goes off.

Meanwhile the Solar Panels will charge the

batteries.

when there is no sunlight the garden light will

switch on.

Time control: There is an eight hours time control, that means

it will go off when the Lights automatically switch off

after 0- 15 hours.

Lighting control Option

1 - Press the power switch for 5 seconds and select the

desired LIGHTING CONTROL option.

The LED is on, which

confirmed you have selected the right one.

2 - The controller requires 10 munites of countinuous

transiton values before it starts to work.

These constraints

avoid false transitions due to lighting or dark storm

clouds.

3.10 minutes off before the controller start to work
