ABB (Power-One) Aurora web inverter monitor (WIM): repair E013 error – 11

I find the Web Invert Monitor very usefully to check the production, but It’s very important when the inverter have problems.

Here the list of common error of ABB Power One Aurora inverter.

Type	Description
E001	Input Overcurrent
E002	Input Overvoltage
E003	No parameters
E004	Bulk Overvoltage
E005	Communication Error
E006	Output Overcurrent
E007	IGBT Sat
E009	Internal Error
E010	Bulk Low
E011	Ramp Fail
E012	DcDc Error revealed by inverter
E013	Wrong Input setting (Single instead of dual)
E014	Overtemperature
E015	Bulk Capacitor Fail
E016	Inverter fail revealed by DcDc
E017	Start Timeout
E018	Ileak fail
E019	Ileak Sensor fail
E020	DcDc relay fail
E021	Inverter relay fail
E022	Autotest Timeout
E023	Dc-Injection Error
E024	Unknown Error
E025	Riso Low (Log Only)
E026	Vref Error
E027	Vgrid Measures Fault
E028	Fgrid Measures Fault
E029	Zgrid Measures Fault
E030	Ileak Measures Fault
E031	Wrong V Measure
E032	Wrong I Measure
E033	UnderTemperature
E034	Interlock Fail (Not Used)
E035	Remote Off
E036	Vout Avg

So last week my inverter start to send me some error messages…

ok, a lot of error messages.

I went to check on the inverter if I had any reports:

and I found the infamous error E013.

I start to search on internet the solution, and I found a lot of article about that, the problem is quite simple to manage, the relay was broken.

So I turned everything off:

And I started taking apart my inverter, by removing the frontal panel:

Than remove all the cables, and remove the screw to the bottom, when remove It you can pull up the inverter and take it away:

Place the corpse of your inverter on a face down plane:

Remove all the screw you can see to the back:

Then remove the screws on the corners of the board panel:

And you detach the main board from the panel:

Now you can check the problem, probably you find a burned part and one or more hole in the board,

you can check the burned relay from the top also:

For replacement I order good quality relays, panasonic JTN1AS-PA-F-DC12V which are a good and safer alternative to Zettler.

You can find here Aliexpress Panasonic JTN1AS-PA-F-DC12V

So you must desoldering the old relay, and install the new:

To fix the hole you must add some copper wire and do a big bubble of tin for soldering:

My friend Pierluigi is an artits on this type of soldering, and he offered to do it for me, for sure the result was better than what I could have done.

And he give me some insulation sheet to prevent the board touch the base, but now let’s start putting everything back together:

And finally:

the light return, and I can see the smile on the Web Inverter Monitor again.
