Solar power is a fantastic long-term investment that can help you substantially cut your greenhouse emissions and electricity bills. In order to ensure you get the greatest efficiency out of your system we strongly recommend that you monitor it regularly. A major part of this involves checking your inverter’s yield.

Use this guide to get started!

If you have a Growatt inverter, a green light should display during the day to indicate that the system is running normally.

To bring the inverter to life and access yield information, simply tap on the cover. The screen automatically cycles between menu options.

The screens that best depict your inverter’s performance are the Etoday and Eall functions. These menu options will be displayed first and second through the cycle (on the second line of the display).

Readings are displayed in the format, XXX.X KWH.

The Etoday provides a daily kilowatt hour reading. Since it is a daily reading, the best indication of production will be towards the end of the day, before the sun goes down.

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

The Eall reading provides an accumulative total of your kilowatt hours produced since the system was installed.

To work out your average monthly production, simply record the difference between your Eall 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)

Like the Etoday figure, this data can also be compared to the yield estimates in your Solargain Customer User Manual.

Sometimes in the morning and late afternoon, as the inverter is turning on or off, it will display a red light and also make a clicking noise. These are both normal functions. 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. Instructions explaining how to reset your inverter are available on our website.

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. Then 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, your inverter will not work until the grid has been restored.
