I have a niggle with my electrics that I need advice on.
I have 600amp hours of Agm
batteries (3x 200 x 12v in parallel)
1x sun power 345w panel
1 x victron 100/30 Mppt
1 x victron battery
management gauge with shunt
Normal alternators on 3ym30 Yanmar
My problem is as follows when I start one of my engines the alternator
kicks in and my amp gauge on the dash shows say 30 then 20 then 10 amps going in and with a loss of 5 amps my victron gauge shows similar positive result (fridge freezer
running so that's fine
With only the solar
my victron gauge shows -5amps on the gauge. When I plug
in the usb cable to the Mppt
controller it tells me the panel is pushing in 20 amps so why is the gauge giving me a minus of 5 amps ?
My solar cables
from the Mppt controller go to positive and bypasses the shunt for the victron on the negative side (i.e. It's on the battery
side not the load side)
Should I move the negative to the other (load) side of the shunt ? Will this correct the victron battery monitor
Last question can I run 2 x victron 100/30 Mppt controllers (one for each panel when I add my second panel) into the batteries without issues ?
