Hi @Dom , Thank you for sharing.
May I ask what are your solar panel parameters (wattage, open circuit voltage, series and parallel)?
If you can specify your solution, we would appreciate it.
Thanks in advance.
I’m trying to find out if the MPPT is even working. I have had several AC faults codes 025 and 026 but I found the 110 plug on the AC300 had come apart and may have caused shorts.
My MPPT problem may have been caused by my over voltage mistake but I have had no error codes and I do get a 9.3v reading from the AC300 DC1 and DC2 plugs so maybe it’s NOT burned out.
It was at 100% charge when I connected the over voltage.
I did hook up two panels only and let it discharge to 30% but it never started the MPPT.
I have 10 panels and can hook up any way you suggest.
It’s 6 panels at 130-140 volts and 5 amp right now.
It’s either a bad unit or I’m just not doing something correctly.
During summer you may get away with 130 to 140, but when the cold weather arrives, it will be much more thabn 150 vots. So, best to remove one panel before cold weather.
The mppt should shut down at 145 volts. Remove one panel, in event it is peaking at 145 volts.
There are online site that will give you the results of your input when -40 temperature (u can choose). Volts and amperage.
Also, I don’t expect the solar would have burnt out your unit, as it is claimed it has over voltage protection. If it did get burnt out, then the protection failed and should be covered under warranty.
Started to see such failure reporting online. A concern?.
Hi @Dom , sorry for inconvenience caused.
As you need to return to the factory for repair, this will require contacting support team via service@bluettipower.com for further resolution, thank you very much for your understanding.
