Connect the cables from PV panels to the solar positive and negative terminals of the charge controller. If

the PV panel voltage and polarity is correct green LED indicator on the front panel glows on. When the

detected PV panel voltage is higher than the connected battery bank voltage red LED indicator glows on

indicating battery charging.

When the PV panel voltage goes below the battery bank voltage the green LED indicator goes o .When the

device detects more than 2Amp charging current to the battery, charging LED (RED) glows on.

If the current is less than 2Amp the Red LED goes o ,but charging continuous in low amp till the solar power

availability.

When the connected battery voltage reaches GRID to SOLAR preset voltage (default 14.2V) the Blue LED

on the front panel glows ON indicating the battery is nearly full charge and ready to use the connected

load either directly from the battery or through a connected inverter.

Automatic Grid power/ Solar Power Changeover function using MPPT charge controller

(Converting a Home Inverter to a Smart Solar Inverter - Solar Management Unit - SMU )

Remove the connected grid phase input wire from the the inverter and connect to the 'PHASE IN' terminal of

the charge controller.Connect another wire from the 'PHASE OUT' terminal of the charger to the input phase

connector of the inverter.

Automatic Solar to Grid / Grid to Solar changeover function

In default mode MPPT charge controller is in AUTO BYPASS "ON" mode.

If it is in "OFF" mode press and hold ( ) ON button on the front panel for 2 seconds to turn it ON.

What happens if Auto Bypass Mode is in "ON" mode

✔

Charger disconnects grid power to connected inverter when the battery volt goes above GRID to SOLAR

preset voltage. (default 14.2V per battery). Display shows INV MODE ON , AUTO BYPASS ON and

✔

LOAD ON SOLAR indicator LED on the front panel (blue) glows on.

Charger connects grid power to the connected inverter when the battery volt goes below SOLAR to GRID

preset voltage. (default 11.5V per battery). Display shows INV MODE OFF, AUTO BYPASS ON and

LOAD ON SOLAR indicator LED on the front panel (blue) goes off.

To turn "OFF" automatic bypass function of the charger press and hold ( ) OFF button on the front panel

for 2 seconds.

What happens if Auto Bypass function is in "OFF" mode

✔

Charger reconnects grid power to the connected inverter. Displays shows INV MODE OFF, AUTO BYPASS

MODE OFF. In this mode inverter will be always on grid power.

What is the Forced Grid to Solar Shifting feature.

This feature helps the customers using the charge controller as SMU. (solar management unit - converting a

normal inverter to solar inverter) When connected battery voltage is at low level (after sunset or in dim sun light)

a sudden heavy load on connected inverter drops the battery voltage below the preset solar to grid changeover

volt and the charge controller shifts the connected inverter load to grid power. It will only be shifted back

to solar mode automatically the very next day when battery is fully charged.If the battery terminal voltage is

above the solar to grid preset voltage (default 11.5v) the inverter load can be shifted back to solar mode again

by pressing and holding (

Multifunction display status

E-TODAY

: Indicates everyday total solar energy production from the MPPT charge controller in units.

:This value disappears overnight and is added to total energy production in Units on the next day.

UNITS

:Total solar energy produced from the solar charge controller in units from the day of installation.

This value resets when goes over 999 units or when battery power to MPPT is disconnected.

BAT VOLT

:Indicates terminal voltage status of the connected battery bank.

SPV AMP

:Indicates available PVpanel input current (Amp) from the connected solar panels.

SPV VOLT

:Indicates available PV panel input voltage from the connected solar panels.

WATTS

: Indicates currently available solar power in watts from the connected solar panels.

CHG AMP

:Indicates current flow (Amp) from the charge controller to the battery and connected load in live.

How MPPT charge controller drives the connected Inverter (SMU)

Charge controller is provided with a relay inside to connect and disconnect grid power to inverter monitoring

the terminal volt of the battery.When the battery terminal volt rises up to 14.2V (adjustable) charger

disconnects grid power to the inverter and the load on it starts running on battery power (solar power). When

the solar charging current stops load will be working from the battery bank and the battery voltage goes

down. When it reaches 11.5V (adjustable) the device reconnects AC mains (grid power) to inverter and the

blue LED goes o . Blinking of blue LED indicates low battery bank voltage. ie. below 11.7 V (adjustable) giving

warning indication to remove heavy load on inverter.
