I recently replaced an 8KVA Quattro for a 15KVA one, as my clients needs had been growing steadily recently. It is a monitored ESS system. Since its installation I am seeing regular overload warnings even though the loads are maximum 7KW. Often showing overloads at under 3000w. It shuts down at least once a day and did it again last night at midnight with a 1500w load. VRM data is giving me no indication of why it is doing this.
Anyone come across similar situation
