Grid Tied Inverter

Three Phase: GT3-5K/6K/10K/12K/15K/20K/25K D1

The LIVOLTEK GT3-5/10/12/15/20/25K-D1 PV inverter is developed for residential or commercial customers
who need a three-phase rooftop model. The Shade Fix integrated shading management system ensures that
the inverter maximizes energy production even when the PV panels are lightly shaded. The machine has a
built-in optional AFCI module to prevent electrical fires caused by abnormal arc faults in the electrical wiring,
with a high safety factor. With 160V ultra-low start-up voltage, ultra-long working time, it’s surely an ideal
choice for large commercial and industrial power plants.

FAQ

Dear Livoltek users or installers, here you will find our most frequently asked questions and their answers, which we have grouped together in order to help you solve your problems quickly.

On Grid Inverter

My router is 5GHz. Can I use it to connect the inverter to my Wi-Fi?

No, currently Wi-Fi dongle can only connect 2.4GHz networks.

How can I limit the power feed to the grid?

A smart meter is required and please set the value of limit in the app Settings – Feed in
Limitation.

My inverter had an alarm saying “PV over current”, what should I do?

Solar panel power cannot be more than 150% of inverter rated power. For example, a 6KW on
grid inverter can connect 9KW solar panels at maximum. Therefore, please check whether solar
panels are over installed.
Or please install 9KW solar panels on two MPPTs instead of one MPPT

Why is the LED not lit up?

The LED is lit up when DC voltage reaches start-up DC input voltage. The start up voltage
varies depending on the power of the inverter.
