Hi everyone,
I have a 24/3000/70-32 Multi II, Cerbo GX, a smartshunt and Smart Solar 250/100. Everything is connected to the Cerbo.
Also 6KW of solar panels.
I want to be able to power my 3KW boiler (and maybe other powerful loads soon, one at a time) almost exclusively from the solar power, but of course, not from the batteries.
So, for the difference between 2400W - the maximum at my controller at full sun and 3KW I’d like to use the AC in to help a little bit the inverter part, limiting the AC power drawn as much as possible.
And not only that. In days with “light gray clouds” when my solar power is limited to 0.8-1.5 KW, I’d like to use all this available sun power, available to the Smart MPPT, and ONLY the difference to 3KW to be drawn via the AC input (as it’s quite expensive, yes). But it’s important that the inverter doesn’t “touch” my batteries’ charge. The point is to combine the available solar power + the grid power at every given moment (I only switch on the boiler during the days).
The Multi is with firmware 552, I strongly prefer to use only Victron Connect if possible, as I don’t have a Windows machine. But if I have to, I will borrow one.
And lastly, I pretty much took a detailed look at the “AC input control” but none of the options there seem to serve what I need.
And advises will be well appreciated!
