So first to be clear here, my IQ8+ inverters work perfectly while grid tied. I have had issues with getting them to work when AC Coupled behind my Schneider WX Pro Inverters when they have lost the grid and are in grid forming mode. Enphase fixed the worst of these problems with a firmware...

Any ideas on an inexpensive voltage / frequency logger? I am looking for something that can help debug issues with AC coupling. So really a Frequency only tool would work. They used to have a really great "Hi resolution" data tab in the Enphase tools. It had voltage, current, watts, and...

Back Ground I have an Enphase system with 35*350 watt panels. It uses the IQ8+ micro inverters at 295 watts each. So the total possible output is 10,325 watts. The actual maximum output is about 9000 watts. I have 7 panels that face east and 28 that face west. The slope of my roof is about...

Sol Arc and the new EG4 18,000 both recommend connecting AC coupled solar to the Gen port. Normally when your system is grid tied excess PV is routed to the grid. In a grid down situation that is not an option. The Hybrid inverter will then become the grid forming inverter and the PV...

With their newest firmware version 521-00005-r06-v02.61.01 the Enphase IQ8s are now able to AC couple with Schneider XW Pro inverters. I had a 35 panel IQ8 grid tied system installed in Aug of 2022. I added a battery backup to the system in Dec 2022. While the system did work fine as a UPS...

I am having two issues with my Schneider that started a few months ago. One is that I am getting Overvoltage F49 faults and sometimes under voltage faults. I have a dual inverter setup, with three Orient Power wall mounted batteries. The faults always seem to be on the same inverter (inverter...

So does anyone else have a Dual XW Pro system? If so is it normal for the slave to only produce a small fraction of the power of the master inverter? On my system when in Inverter mode I might have something like this: Master: 0.65 KW Slave: 0.15 KW Every thing works fine. I am just wonder...

I have this system all setup. In Grid tied mode everything works great. There is a problem getting the PV inverters to turn on after disconnecting from the grid. I saw a similar post from someone trying to make this work with a Solark. The system runs fine on batteries, but the whole point...
