Resetting an Aurora Solar Panel Inverter
Вставка
- Опубліковано 6 жов 2024
- Had Installed a Solar Panel Electric to produce Electricity to use and put back into grid. Shortly after installation saw a GFI fault coming up on the inverter and showing a short. The following morning reset itself and everything was working fine. However 4 years down the track and in the Winter the Inverter would not turn on. The system is not for simple-minded householders to have installed. Lucky I had good insurance on the panels and have had the crook panels changed out
Common fault with these is a burnt out solder joint due to relay contact high resistance and resulting heat. Fault shows as RISO fault at start up, see Andy Reynolds channel for how to fix. It is not a difficult job.
Will do Thanks for your advice
This is complete nonsense. Andy's note relates to error E031 - not RISO (Resistor ISOlation)!
@@blacksenator7333 Yes it is a different fault, the fault I describe is very common and if you have one of these inverters there is a good chance it will get this fault. Good news is it is not hard to fix if you have some skill in repairing PCBs. But obviously you just like to be a troll rather than offer anything positive.
Hi can I ask about error 015 bulk cap fault
I have no idea what this fault is. Maybe Google it to find out
I had the same error. Moisture got into the modules and caused short circuits and correspondingly low resistances.
But what you present here as a "solution" is a complete misinterpretation of your observations: apparently you are running two strings. The check for resistance errors is done at boot procedure. If you only connected the first string at startup (by first I don't mean either of them but actually the one connected to number 1!) - which apparently has no resistance error, then everything is fine. You just add the second string later when the check is done. But no later than the next morning when both strings are connected and the inverter starts again, it will switch off again due to a resistance error.
We hang on to:
- the inverter always starts when the string connected to input 1 is error-free
- if a "faulty" string is connected to input 2 after the start-up process, the resistance is no longer measured
- this process would have to be cascaded at every start
- It is better to repair defective generators and/or DC lines, i.e. fix the cause instead of symptoms
Total nonsense , solve your defect leaking cables !
Have already had that done by a specialist many times now.
No leakage happening except on Faulty Panels is the story told to me and they have been replaced. I have done a visual also to try to find where the moisture is getting in. No luck so far.

Hello Gary
This is not so difficult to find
The riso error is a earthleak error on the DC site
Disconnect the panels on the dc site MC4 connectors from the inverter
make sure the dc disconnect switch is in the on position
so it is NOT disconnected
Take a multimeter and measure between the plus and minus of the cables from string 1
the cables that come from the roof ofcourse
you show in tour video that you have 415 volts on DC
This means that in not connected panels string should be about 460 volts as you have 10 panels in this string i think
so you should measure about 460 volts (can be different)
now take again the multimeter and stick one pen on the outsite of the inverter (the earth) make sure you have a good contact
maybe stick it under a screw
the other pin of the mulimeter you connect to the + cable that is coming from the 1e string (just measure one cable respect to earth)
the meter should be on DC measurement same as before
now you should measure nothing or just a small voltage
Let the earthpen stick under the screw and measure the minus cable from the same string
again you should measure nothing or a small voltage
If you know where the cables go , makes it more easy to find the faulty one , when you measure a voltage multiple to one panel
if you measure for instance between the plus and the earth a voltage of 46 volts then the problem can ve found between the first and second panel
if you measure 4x46 = 184 volts , then the problem is between panel 4 and 5
if you measure 460 volts then the problem is in the main cable to the roof
this means that you measure nothing on the other pole from the string
if you measure almost nothing then there is no problem at the time
do this also with the second string
if there is also no problem then go take a garden hose and spray all the roof and panels
and do the measurement again
good luck
@@draaistroomnederland3784 Thanks but because I am still under warranty I am not allowed to touch the panels. Thank you for your help. My Warranty will soon run out.
@@GaryPArmstrong After 11 years (manufacturer's guarantee 5 years - but performance guarantee 20 years!), my manufacturer replaced the entire installed capacity with new modules because more than 10% of the modules had a proven short circuit caused by moisture damage (= capacity 0)
