G'Day All, Recently ran into an issue on a system installed by others. It's an Outback FW1000 circa 2015 with a twin stack of VFX3648's. The system is offgrid and charged solely by a 15kw propane fired generator with plenty of hours on it. I'll be adding PV to it in the coming weeks. The system originally came with a Mate Oval using the AGS. In late 2018 a second installer replaced the oval with a Mate3, serial# M307410. The system has been working with the AGS feature flawlessly.
A couple weeks back I received a call because the Mate3 had locked up. So I arrived last week with a new Mate3s in hand, serial# MA2007F0100150 not a Mate3. I removed the SD card from the Mate3 and installed it to the Mate3s. It appeared that someone had saved a profile so I loaded it into the newest Mate3s. After reviewing the settings I was satisfied with them and fired everything up and then manually started the genny. After an hour or so I shut down the genny again manually. The AC power went out and on the Mate3s I received an event, "AC Out shorted Error". This seemed odd as there were no other changes to the system other than to swap out of the Mate. Tried this several times with the same results. Next I decided to turn off the home's main breaker @ the SEP. Did not get any error's at the Mate3s. Next I turned on the 200A main @ the SEP. Still good. Then one by one all the breakers in the SEP. No error's and the power is back on. Fired up the genny, then turned it off and the same error reappears. Here's where it gets really interesting. The client still had the old oval Mate lying around so just for fun I reinstalled it and everything ran perfectly. Say what?!?! At this point I'm leaning to either an incompatibility issue with the new Mate3s and the older VFX inverters or just a bad Mate3s. What say you?
