Generator shown as grid in VRM

Why my generator is showing as grid in VRM? We are off grid, so basically this is not a problem, but is there any way to change this? 1648208777740.png

Ok, answer to myself. Found the solution from Remote Console. Settings-> system setup.

Hi @kkiksu

You can change it in the GX..

Just as an update, VRM now counts and displays generator and shore power input (just like the Grid), so you can set it accurately with no loss of functionality.

Okay, thank you for the advice! Already asked elsewhere, but i'll try my luck. Can I enable battery monitor and rely on readings with my system setup where I'm using both solar and generator for battery charging? Or do I in this case need smartshunt?

The Multi/Quattro SOC is a pretty basic thing, and is less useful with solar (there used to be a setting in the GX to tell it to add in the mppt data, but I'll let you find it). Makes the result a bit iffy. Ok if you're happy with iffy..

The real beauty of the Smartshunt is that (with DVCC) the mppt can then use the battery current to terminate Absorb at a Tail setting. Up to a max of 10A, so check that before buying for that reason.

I've a well-tuned Sshunt and it returns to the sync point every day to within 0.2% SOC either way. That's pretty good, and even some of the monitoring means don't run to using a decimal point.

Depends on how accurate you want to be. Batts are expensive though, and I think the shunts are great value.

@kkiksu, What inverter you use in your installation? A Multiplus 2 or a Quattro? We are running a grid parallel MP 2 and i want to install a second inverter, a Phoenix Smart Inverter, to increase the ouput power of the MP2. Saw this in a youtube video from Andy from the "Off-Grid Garage" and he starts the Phoenix with the "Generator Start/Stop" assistant load dependend. Works very well. And it would be great tho see the generator tab next to the grid tab as AC input.
