Macsolar Inverter Error Codes

by | Sep 24, 2016

We are hearing from more and more people who have a Macsolar inverter, and it doesn’t appeamacsolar inverterr to be working.  The hardest thing to tell with a Macsolar is if it is faulty or not.  Some error codes mean there is a problem with your solar on your roof, or your grid. While other errors mean the inverter is faulty.

How can you tell?

Firstly, which lights are lit up on the front of the inverter?

You should always have  the green ‘working’ light, and the orange “run” light.

If you don’t, start by rebooting your inverter.  If you’re not sure how to do this, see here

Once you have checked all the switches are on as they should be, check the lights on the front of the inverter.  Macsolar have the following information in their manual:

Fault Grades Description Power (Green Light) Run (Orange Light) Fault (Red Light) Event Nos.
A Inverter has stopped due to equipment fault ON OFF ON 10, 12, 13, 14, 15, 16, 17, 18, 19, 21
B Inverter has stopped due to restorable or environmental faults ON OFF Flash (1Hz) 0, 01, 02, 03, 04, 05, 06, 08, 09, 11, 20
C Voltage dependent resistor fault ON ON Flash (1Hz) 07

Where Do You Find The Event Code?

The next thing to find out is – what event code do you have on your inverter?  Macsolar did not make this intuitive to find, unlike other inverter manufacturers.

There are a few different models of Macsolar, so here are a few examples of screens with error codes:

Macsolar error 19 relay failure

In this example you can see the number 19 just below the date on the Record Info page.  This inverter has a relay failure, which means broken.  This is the most common error we come across on Macsolar inverters

mcsolar error 19



On this Macsolar inverter the event code is found on the Fault Info page, spot the number 19 again just below the date.


macsolar event 0


On this model of Macsolar the event code is on the Record Information page, spot the ‘0’ directly under ‘Record Code’ – not the most obvious, is it?


As you can see, it is not always easy to make out the event code, so hopefully these pictures will help.

Once you have the event code, check what this means by looking at the list here

macsolar labelWhat Should You Do Now?

Give us a call, letting us know the event code, and the model of inverter you have.  This can be found on the side label of the inverter (and if it says DUAL MPPT, this is important information to tell us).

Macsolar are no longer in business, so you have no warranty with them.  However, you may still have a warranty with your retailer.

If your inverter is less than 5 years old, and the company that you bought it from are still in business, go back to them.  They have a legal obligation to replace it under warranty.  If they are no longer trading, and you live in Adelaide, give us a call and we can quote you on a new inverter, and get your solar back working again.
