Have you just checked your MacSolar solar inverter and been greeted by a red fault light? Did you also notice an Error Record Code 19 on the screen?
If so, I’m really sorry.
When the red fault light is lit on your MacSolar Solar Inverter your inverter isn’t working, and if the sun’s shining that’s not what you want to hear! It’s a good thing you noticed because now we can take action and quickly diagnose the problem before it costs you any more money.
First off, when a MacSolar solar inverter is operating properly, there should be two things present:
The “Power” light should be lit green.
The “Run” light should be lit green.
If one of these lights isn’t on your inverter is probably still trying to start up. You should hear the relays clicking inside the inverter as it attempts to startup. If the solar inverter fails to properly start up, the red “fault” light will be lit as in the picture above. This indicates your MacSolar solar inverter has an error and needs attention.
What error does your MacSolar have?
When most solar inverters have an issue they will very clearly display it for all the world to see, however MacSolar inverters are a little more secretive when it comes to their error records. To find the reason your MacSolar inverter is showing a red light, click down on the menu to the “record info” option and hit “enter”. If the interface indicates “error record code 19”, as in the picture above it means your solar inverter has had a relay failure. This is an internal problem and it’s quite likley you’ll have to replace or repair your inverter, but it is best to try rebooting it first before giving up all hope.
How to Reboot Your MacSolar Solar Inverter with Error Record Code 19
There should be instructions on the side of your inverter on how to do a full reboot as follows, please follow the steps:
Turn OFF the solar supply main switch (or inverter AC isolator if present).
Turn OFF the PV array DC isolator.
Wait for the inverter screen to go completely blank
Turn ON the PV array DC isolator.
Turn ON the solar supply main switch (or inverter AC isolator if present).
Wait a few minutes while the inverter boots back up.
If after waiting a couple of minutes for the solar inverter to fully power-up, the red “fault” light comes on again, your solar inverter will require replacement or repair.
Unfortunately MacSolar is no longer in business, so your inverter will not be covered under warranty. It is possible to pay around $500 to repair your inverter, but that would still leave you with no warranty and an inverter that could develop another fault at any moment. If you do choose to go the repair route, the inverter Model # and wattage are located on the information plate on the right side of the solar inverter and will be useful to any repair company you speak with. That being said, we highly recommend replacing faulty MacSolar solar inverters with a quality new inverter backed by a full manufacturers warranty.
