I've been trying to figure this out. Spent a lot of time researching and today tried for several hours, but came up with nothing. Even tried using a Self Consumption Hub, but ended up with: Using VECONFIG I set it up and then you select a policy. All but two are deprecated. I tried the two and I could not get any AC power, I received a Error 6 - Error in DDC Program.
Victron, here is the ideal solution, which might not exist in your firmware, but it is to dynamically limit the AC Input based on the solar and based on the AC Demand.
I.E. If the AC demand is 2000 watts and we have 500 watts of solar, limit the AC Input to 1500 watts. If the Solar is 1500 watts and demand is less than that, switch to Inverter. I'm hoping, if the AC Input limiter cannot handle frequent changes, then give us a threshold. The goal is to use direct solar and avoid tapping the batteries so we aren't charge/discharge.
Please point me in the right direction, or take this as a feature request.
