Hello
I want to put in a request on Victron Cerbo.
Timer mode or something:
Timer mode set that you can say, I want to use batteries from say 22h00 until 09h00 in the morning and if batteries get to say 40% SOC, It must start using Grid/Generator and stay at 40% SOC until the PV can charge it back up to 100%.
like Sunsynk got this option.
This will help so much.
Thank you
This is achieved with node red and venus os large.
Possibly dynamic ess as well. Although i have not tried it that way.
The other way is conditional ac connect can be done with victron connect.
A further way, which has been a favourite is to use, if you cant really program, is the generator start stop on the gx wired to a relay on the inverter. The relay programmed to connect or disconnect the programmable relay based on conditions set on the GX.
I will need to learn node-red. I get so lost at the start.
There are plenty guys who have shared code with ideas.. A copy paste and tweaking works.
can Node-RED tell Cerbo only to charge the batteries with PV first and after the Batteries are full to do supply load/grid feed..?

I have a MultiPlus-II GX, I guess it works the same way as your Cerbo.
To charge the battery first with PV I use ESS and Optimized (without BatteryLife) modus.
For your other question charging at night, I'm using Node Red.
I use the relay out of the Cerbo to connect to the AUX of the multiplus. It gives a lot of functionality from VRM you can use quiet hours or periodic run.
You can set different SOC levels for quiet hours to normal.
