How to prioritize Solar in a Lynx BMS setup?

My setup is all Victron with a Lynx BMS, Cerbo GX and Victron solar controllers connected to the GX. I want the solar to be maximized and shore power only used in certain conditions.

I found someone who set up ESS to do this, but have been advised here not to use ESS.

Other answers say to set the charging voltage slightly lower on the Multiplus.

But my understanding is that the BMS is setting the target voltages that both the Multiplus and MPPT controllers are using.

maybe there’s a way to limit charging on the Multiplus to inly happen below a specific SOC? Or during specufic time periods?

There's an ignore AC input function accessible from the Cerbo.

In the settings, select the multi, settings, advanced and you will find it. Just have to remember to set/reset as needed.

Victron are looking at your and similar requests. No promises on if/when it will be implemented.

Is this a mobile installation? That really would be the only reason not to use ESS to prioritize solar over grid, as long as you 'follow the rules'

That's the whole point, the other posts show this and that explains the opening.

Correction. The ignore AC switch cannot be set in the Cerbo. Sorry.

Please take a look here.
