Is it possible to feed power from one Victron installation to another?
We live completely off grid. My camper has a complete Victron system (with 2 x MP 3k 2x120 in parallel) with 22kw storage and 10kw of panels. It is largely unused.
My house is a Victron system (with 2 x Quattro 5k in split phase) and 49.2kw storage.
Is it possible to send power from the camper to the house? It would be awesome to have incoming power through the night I’m thinking this would just be AC out to AC in? Is it that simple?
Split-phase will make it more challenging, but I have this working using ESS. Most of the time I’m grid-connected, but I can also use two small ESS units in the shed connected to the AC output of the MultiPlus 5000VA when I lose the grid. I have 24V and 12V 1200VA MultiPlus units in the shed. All I needed to do was install an energy meter on the consumer unit, a Shelly EM. It’s amazing how well it works.
This guy in the video does it slightly differently, but he also hooks up micro inverters to the van. What he is doing in this video is using ESS and sets the grid setpoint to -100W, which feeds 100W to the house. The good thing about ESS is that you can set the SOC to stop exporting 50% for example. This setup does not have an energy meter, and no idea what the loads in the house are.
You might be able to wire the parallel inverters so you can change them to independent and connect to separate house phases, still using the same battery.
I might need to set it up like this once or twice a year for a power outage. I am using an RPI in the shed with Venus, and all I do is change the SD card with a different configuration. You will need to use VeConfigure to change the multi settings and install the ESS assistant.
