Is the Venux GX required to control charging and discharging from the grid?

Hi there. I hope my non-technical language is understandable.

I read some of the answers in this forum but there is always some terms unknown to me that does not allow me to fully understand.

I live in an African country where power outages are not daily but weekly. But really expensive. A part the line connected to the national Grid, I have a dedicated circuit used to supply loads continuously.

I have :

Solar panels for 4,200 Watts,

Multiplus 24/3000 inverter / Charger

Victron Mppt charge control (I don't remember the power)

N ° 4 x 200 Ah batteries


I would also buy the Venux GX to get:


1) If the power of the solar panels is sufficient to power the connected loads, I would disconnect the grid and use only that produced by the panels, and if necessary the batteries but only within a limit of 50%.

2) I would also like that, if the production of solar panels is not enough, low amperage from the network was used to charge the batteries.

Kind regards

Hi Aldo,

Yes, you can do a lot with ESS on a VenusGX.

Hallo! You can also acheive roughly the function you describe with only a Multiplus. You can use a function in the Multiplus called "Virtual switch" to connect to grid when battery voltage is a bit low, charge from grid to a somewhat higher voltage, disconnect from grid when even a bit higher. I use this and it works. Br Tomas F.
