Tata Docomo — R R number 78500 voltage fluctuations from T C resulting in damage of solar inverter

Address:	Plot no 20 Eshavasya building Kulkarni layout opposite to basav nagar near shivalaya haliyal road
Website:	Hescom hubli

Sir,
From past 5 days solar inverter was not working.
The error code was 504.
The inverter company technician told that it is due to the problem in T C .
When it is set right the inverter will automatically work.
Today morning the same thing happened.
The four pole contactor started making sound and then inverter started working.
So please do examine the T C and give the permanent solution.
I was submitting complaints from past 15 days but no one above line man catagory has visited the site. This is sheer negligence from Hescom authorities.
For any damages they should be held responsible.
