Hi Victron Team,
We (DPA Solar) are an Australian Victron distributor and have sold a number of MultiGrids to installers who have set up 3 Phase systems. Two installers who have installations with BYD are experiencing some occasional error10 and error3 issues resulting in system shutdown. This is happening roughly about once a month. The systems can't be reset remotely and need the installers to attend, or for the homeowner to shut down and restart. One installer has noticed that when a grid failure is simulated (with loads on), the load side loads briefly went off then came back on after a couple of seconds (in off grid mode). However, when the grid was reconnected, the Multigrids went off, attempted to reconnect 3 times but would not power up (while loads were still on). Error 10 and Error 3 notifications are present. Only when loads were switched off, and the MultiGrids were powercycled, would the system come back up.
We're keen to hear if this has been experienced by anyone else and/or if this could be just when BYD batteries are used with 3phase MultiGriss, rather than with self-managed lithium or lead battery banks. And if there are any ways to overcome this.
Thanks
David / DPA Solar
