5-Warranty


Manufacturer provides  2 years warranty from invoice date for solar charge controllers.
Please read the following instructions carefully. Free guarantee service will not be provided to the said equipment if

1.It has been installed and operated otherwise than in accordance with the instructions

2.Any unauthorized repair or modification has been carried out on the unit.

3.It has been damaged through natural calamities.

4.It has been damaged through transportation or storage.

5.Batch numbers, serial numbers or identification-marks are manipulated or are unidentifiable.

6.Load connected has been damaged due to incorrect, reversed connection as controller is equipped with solar panel and battery reverse connection protection, but no REVERSE LOAD CONNECTION PROTECTION.

7.It has been used to control power generated from any other type of device such as a Gasoline Generator rather than a solar panel to charge a lead acid battery.
