Monitoring your Samil inverter is a fantastic way to further improve the already impressive savings provided by your solar energy system. Doing so allows you to better optimise your energy use, and make better use of the solar power generated your system. Read on to learn how.

Use the guide below to get started.

If you have a Samil Power inverter, it should be displaying a green Normal light as it runs during the day.

To check your system’s performance, use the function button to take you to the page proceeding the first Normal State page

This page will have an Etotal on the top line like the example below:

The Etotal figure refers to the accumulative energy production your system has generated since installation.

To work out your average daily production, simply record the difference between your E-Total figure at the start and end of each month.

For example:

E-Total on 1st January is 1100

E-Total on 1st February is 1300

January’s Monthly Yield is therefore 200 units (1300 less 1100)

January’s Average Daily Yield is therefore 6.45kwh (200 monthly yield divided by 31 days in January)

You also can check this figure against the averages provided to you in your Solargain Customer User Manual given to you in the black handover folder on the day of installation. If you cannot find this manual please call Solargain on 1300 73 93 55 and we will send a new one to you.

Pressing the Function button again will take you to the next page, Etoday.

This tells you your energy production for the day. Since it is a daily reading, the best indication of production will be towards the end of the day, before the sun goes down.

Samil inverter service and repairs

If your Samil inverter is experiencing any non-monitoring related issues, then follow the link to this page: Samil inverter service and repairs. If you need any assistance, please don't hesitate to get in contact with our team.


Sometimes in the morning and late afternoon, as the inverter is turning on or off, it will display a red fault light and make clicking noises. This is normal. You should also note that the inverter’s sound increases as it works harder and produces more wattage. Any internal issues with the inverter will be detected by the device and will cause the fault light to be displayed permanently.

If there is ample sunlight outside and your inverter is displaying a red fault light, you will need to conduct a reset. Read instructions explaining how to reset your inverter.

If, after resetting, the red light is still on, please retrieve the error code displayed on the screen as well as your serial number from the side of the inverter, and contact Solargain on 1300 73 93 55 and we will happily assist you to resolve the issue.

Please note - if you have no power in your house due to a blackout, then your inverter will not work until the grid has been restored.
