We experienced the precise problem you had a couple months which eventually lead to trying the above steps. After a frustrating number of C.S. calls and getting bumped between multiple representatives with varying levels of success we ended up getting replacement equipment from Sol-Ark. We first noticed there was an issue when we would make parameters changes to Inverter 1 the troublesome inverter (no. 3) would seemingly at random revert later on. Inverter 3 was also constantly displaying a slightly different battery voltage than its three partner inverters. Once we replaced the equipment sent by Sol-Ark we haven't had a parallel system stop and the parameters remain consistently mapped across all units.
