I had a grid metre in my camper and no inverter. I’m just starting the install of a 48/3000 inverter and wondering if I should retain or eliminate the grid metre. I don’t backfeed to the grid or anything like that. Just an Overlanding camper. I was searching for information on this and I came across the old archived forum and somebody posted two pictures one with a grid metre and one without as viewed from the control panel, but of course the images are no longer shown .I have it is there any reason not to use it?
Technically its not necessary to use a grid meter. And depending on the type used it might not even be compatible with the Victron system. Apart from that, you would also need a GX device to read it out and present the data as a system.
I guess with inverter you mean an inverter/charger like a Multiplus. If your AC loads are all fed by the MPs ACout then you dont really need a grid meter, since theres no loads inbetween the grid connection point and the MP which could be displayed.
If you have loads that are fed only by the grid, so they are located between the grid connection point and the MP, then you could think about using a grid meter.
I personally would feed all loads from the ACout of the MP. If you have something that should not be powered if theres no grid available, then you can use the ACout2 for that.
