on the unit and in this manual carefully.

• Selec Controls Pvt. Ltd. is not liable for any damages caused by failure to observe and follow these

instructions in the manual.

• Qualified person should also be familiar with local requirements, rules and regulations.

1.4 Additional Information

www.selec.com

NOTICE

• Once a year, turn the rotary switch of the DC disconnect switch from the “ON” position to the

“OFF” position 5 times in succession. This cleans the contacts of the rotary switch and prolongs

the electrical endurance of the DC switch.

8.2 Cleaning

WARNING

• Before starting cleaning of inverter, please ensure that DC switch is turned off and the AC

breaker present between GTI-SERIES inverter and grid is also turned off. After switching off

the DC switch and AC breaker wait for atleast 5 minutes to avoid risk of electric shock.

CAUTION

• Risk of burns due to hot heatsink.

• The heatsink may exceed 70 C during operation. Do not touch the heat sink during operation.

Wait atleast 30 minutes before cleaning until the heat sink has cooled down.

• Do not use water, corrosive chemicals or detergent to clean inverter and heatsink.

• Please clean the inverter with an air blower, a dry & soft cloth or a soft brush.

• Please ensure that there is enough space around the heatsink for ventilation. Inspect the heat

sink for blockage (dust, snow, etc.) and clean them if they exist using an air blower, a dry and

soft cloth.

• Turn OFF AC breaker.

9. Decommissioning of inverter

• Turn OFF DC switch.

• Remove DC cables

• Remove AC cables.

• Unscrew mounting screws to remove inverter from wall.

• Adopt E-waste Regulation guideline while disposing faulty inverter. Do not dispose inverter with

household waste.

• Wait till i) Alarm LED turn OFF ii) LCD light turn off.

• Remove Rs-485, Dry contact DI terminal connection if you have done any.

• Unscrew Communication plate.

• Wait for approx. 30 minutes before touching Inverter. Surface may be hot.

• Pack inverter in carton which is provided during purchase.If that carton is not available then

use equal size carton.

• Unscrew AC Connector.

• Unlock Communication gland.

2.1 Intended use of inverter

GTI-SERIES inverter are Grid Tied Solar Inverter. When sunrays fall upon the PV array, DC power is

generated by these arrays. This power is fed to the inverter as input. Inverter will convert this DC power

into AC power and feed it to three phase utility grid. GTI-SERIES are two string inverter with two

independent MPPT trackers.

Overview of complete Grid Tied PV system with GTI-SERIES inverter :

2. Product Overview

As shown in Fig 1, the complete system consists of PV array, DC distribution box, GTI-SERIES

inverter, AC distribution box and utility grid.

Caution

• Check AC & DC Voltages are within range of particular GTI-SERIES inverter specification.

• Check protective earth is connected.

• Check DC connectors are connected.

• Check AC connectors are Connected.

7.1 Initial turn on of inverter

• Turn ON DC switch . As soon as DC switch is ON , LCD display will glow. There are two LED

indications on front sticker. Red is alram & Green is Grid feed status.

• Inverter starts self test, for checking internal circuitary is proper or not before doing grid feed.

• If any fault occurs, then alarm LED will glow in red colour this will alert user regarding a particular fault.

• If every thing is normal then, inverter starts feeding power into the grid . Grid status LED will

glow green.

8.1 Maintenance

WARNING

• Before any maintenance, please switch AC and DC power off atleast 5 minutes before proceeding to

avoid risk of electrical shock.

• Normally, the inverter needs no maintenance. Check for any external visible damage and discoloration

of the cables and DC switch at regular intervals. Check that all terminals, screws and cables are

connected and appear as they did upon installation. If there is any visible damage or visible

discoloration of cables or DC switch or if there is any impaired

and loose part, please contact the installer.
