I have a Multiplus 48/5000 in ESS set-up with grid meter and 150/60 MPPT. I have set up the minimum power from grid at 350 watts to prevent feed-in. When a large load, such as an oven switches off, the inverter output is reduced too slowly, resulting in a small feed-in to the grid. This causes the Utility meter to sense back-feed and switch off the mains supply for a short period before resetting.
I see in the latest firmware 454 for the Multigrid, there is mention of improving the response time for feed-in control.
Is this something that could be extended to the Multiplus quite soon?
