William Sounds like the inverters are in search not on, have you changed the inverters to on instead of search. Have you considered a hard reset to factory. Also as a POE (process of elimination) I would turn off one of the slaves at a time, even switch over to a different master. I had a 16 kg in Hana that after 2 years started doing that kinda issue, it ended up be programming issues, why? dont know but it can happen. I just did a new mate 3 software update and it scrambled all the utility settings so keep notes of everything that you ever change just in case Jerry
