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 Fronius inverter, start by accessing your main screen menu.

There are two main readings that you should note when checking your system’s performance: the Day reading and the Total reading.

Use the key (A) button to move the arrows on your menu screen. When the arrows are facing in towards the Day or Total, use the key (D) button to select.

The Day figure is the amount of kilowatt hours your system has produced for the day. Since it is a daily reading, the best indication of production is towards the end of the day, before the sun goes down.

You can check this figure against the yield estimates provided to you 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 other figure is your Total.

This is the accumulative total of your kilowatt hours produced since your system was installed.

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

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

Troubleshooting

Sometimes in the morning and late afternoon, as the inverter is turning on or shutting off, its fault light might be on. It may also make clicking noises. Both of these are 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 the status light is flashing orange or displaying red, then you should conduct a reset.

If, after resetting, the lights continue to flash orange or red, then there will be a fault code that appears across the bottom of the screen. Please record this error message as well as the serial number of your inverter, which can be retrieved from the side of your unit.

Then contact Solargain 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.
