If you want to make the most of the fantastic savings that a solar energy system can provide it's important that you use your inverter's monitoring capabilities regularly. Read on to learn all about how to monitor your Delta inverter.

Use this guide to get started!

If you have a Delta inverter there should be a green Operation light on when the system is running normally during the day. To check your inverter’s performance, follow the directions below.

Along the bottom of your screen there are four buttons which we refer to as A, B, C and D.  See below for the corresponding button locations.

To light the display press button D.

Now use button B or C to navigate through the menu options. There are seven menu items.

The two pages which provide the best indication of performance are Menu D (Day) and Menu T (Total).

To assist your navigation through the menu, you can view the order of the menu items below. Once you have highlighted the appropriate menu item, use the D button to enter it.

Once Menu D (Day) has been selected, scroll down once using button C.

This will bring you to - D->Energy Value WH.

The Day figure is the amount of watts per hour you have produced for that particular 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. You can check this figure against the ones provided to you in your Solargain Customer User Manual, which you should have received in a black handover folder on the day of installation.

If you cannot find this manual please call 1300 73 93 55 and we can arrange to have a new one sent to you.

Once Menu T (Total) has been selected, scroll down once using button C.

This will bring you to T-> Energy Value (kWh).

This is an accumulative total of kilowatt hours produced since your system’s installation.

To work out your average monthly production, simply record the difference between your T (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 D (Day) figure, this data can also be compared to the yield estimates in your Solargain Customer User Manual

Delta inverter service and repairs

Delta inverter service and repairs is your go to page for all Delta inverter issues that are not related to the monitoring platform. If you need any assistance, contact us.


Sometimes in the morning and late afternoon, as the inverter is turning on or off, it will display a yellow failure light. You may also notice that it’s making a clicking noise. These are both completely 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 failure light to be displayed permanently.

If there is ample sunlight outside and your inverter is displaying a failure signal, you will need to conduct a reset. Instructions explaining how to reset your inverter are available from our website

If, after resetting your inverter, you notice that the failure light is still on, please retrieve the error code displayed on the screen as well as the serial number from the side of your unit.

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.
