My Multiplus II GX only runs sporadically. However, I have several DC loads running. I am therefore thinking about switching off the Multiplus when not in use and supplying the Multiplus GX card externally. Does anyone know if the GX card has the same power range as the Cerbo GX? I read a report that it runs on 12V, but will it also work on 48V?
Hi @Hari OffGrid,
The GX card that is inside the MultiPlus-II GX and EasySolar-II GX has a power supply rating of between 8-70V.
However I personally wouldn't supply less than 12V or more than 60V (that said I wouldn't bypass the internal power supply at all). You have to be extremely careful that there aren't any voltage spikes which can happen on cheaper power supplies when connecting and disconnecting.
Can't you just switch the inverter component off via the GX interface? That should maintain power to the GX part, but not run the inverter part.
