I've searched the forum to find similar issues with what I am trying to resolve, but didn't see an exact answer or resolution. Here's the problem I'm trying to resolve.
I have 22 - 250w solar panels with a Sunny Boy 5000 inverter.
The system has been flawless over the past 2 years.
Voltage at the service panel, that I have measured, ranges from 255v to 265v. :blink:
This is not a US installation..... install is in Mexico.
Recently, about 10 times over the past 2 months, the inverter will report grid fault errors when the voltage over L1-L2 exceeds 264v.
I've had the PoCo here several times to troubleshoot this. Each time they come out, they report no problems.
L1 and L2 would read between 128-132v. This they say is within their acceptable range.
Will a buck transformer do the trick, if installed at the service panel, to maintain 240v over L1-L2?
And will a transformer work with a PV system installed?
Any feedback will be greatly appreciated.
