[RE-wrenches] Primo with tigos Arc fault issue

[scot.arey at solarcentex.com]

A long time ago when we were using Sunpreme bi-facial frameless modules, those modules caused a much higher incidence rate for the dreaded 240 arc fault code on Fronius inverters. Fronius was good about addressing and tweaked their algorithms (I wish I knew what that really meant…) and the incidences decreased.

So when I saw this, it brought back memories and got me thinking if Fronius just has a hair-trigger fault process.

Fronius Primo still the only 240-volt string inverter I can use for ground mounts with 1,000volt rating. Maybe others out there today that I don’t know about but the 15KW and 12.5 string inverter was so important for us in the past.

Hi Jeremy! 

 

We have encountered this his issue years ago with the AO and Fronius suggested we deactivate the arc fault setting. It works, but in order to do so, they give you a special passcode to input. Not an ideal solution. Arc fault detection is not worth compromising . IMO avoid this combination by all means. 

 

Kindly,

 

Chris

 Has anyone had issues with Tigo TS4AF rapid shut down devices along with their transmitter, causing arc fault codes with a Fronius Primo inverter? 
Fronius tells me I need to use AP smart devices. Hmmm.
