Virtual Switch Ignore AC not working on Multiplus with Firmware updated

Hello Dear Community and Staff,


We have a 3 phase system with Multiplus 2000VA inverters, Smart Solar Chargers, a CCGX and a Battery monitor BMV712. We want our system to use the grid only when batteries SOC is below 50% and when Load exceeds 1600W after a couple of seconds.


Somehow the Virtual Switch is doing its job for the battery SOC condition but not for the load condition, we tested with a constant 1800W for 60 seconds and the AC inpunt won't come in. This is important for us, as some loads in the house come in really fast and take the inverter inmediately to overload.


Does any have had this problem? what could be missing?


Please finde below some screenshots of the Virtual Switch configuration at VEConfigure for L1 Inverter.


Thank you!


Carlos.

Up to 8 attachments (including images) can be used with a maximum of 190.8 MiB each and 286.6 MiB total.

Also wanted to add that the Virtual Switch does work for the battery conditions that were set but not for the Load ones. Thanks!

On the Inverter Tab what did you choose for Power Assist?

Hello Peter, thanks for your reply.


We have Power Assist Checked with Assist current boost factor 2.0. Does this influence the virtual switch behavior?

Dear Community and Staff, we have news. This is now working OK but only for L1, when loads on L2 or L3 surpass the load limit of the Ignore AC parameters it won't. Isn't this supposed to switch as a group if the conditions are met on any of the 3 phases? Is there additional configuration to be made?. Thanks!

helloi found an information somewhere in this forum that we need to hard wire the multi and set an assistant to get it work.,cause only the L1 can switch the VS.

when you set battery condition it apply for the 3 multi in the same time but load condition apply only on the concerned multi if its not the L1 the vs will not switch

i didn't find anywhere how to hardwire the multis togather to get it work
