Hi Newbie here with limited knowledge so be gentle! I have just purchased a secondhand motor home with 2 leisure batteries and the VE BMV 700 battery monitor. I have a 1500w inverters already from my old motorhome and want to connect this to my new one. My old motorhome did not have a monitor (or shunt) so the connections were straight forward - batteries in parallel and inverter positive connected to battery 1 positive and inverter negative to battery 2 negative. How to I wire my inverter with the shunt and 2 batteries? As above or does one or two connection go to the shunt? I attach some photos.
Secondly I am not sure why the BMV 700 was used given there are 2 batteries. Am I right in saying that this can only provide info on the one?
