comment for new stuff.
the solar shunt needs to go between the solar contoler and the ground terminal. not between the ground bus and xantrax shunt. otherwise it's trying to measure both solar and charger current
which is probably too much for it to handle.
the pos of the solar should go to the house bank direct before the switches. so it charges when the swtichs are off. as mentioned above.
the whole swtich / shunt setup is dumb. they've used the dual shunt but then tied the batteries together into one bank anyways. and also the right hand switch doesn't actually change batteries.
waste of wiring and adds confusing.
also it looks like they ran cables
from the alt to the house and start battery. which means you actually don't even have 2 banks. you only have one as they are all paralleled together through the alt cables. you need a diode block in there to do that. and even if you turn the engine
battery switch off you are still draining the engine battery into the house...
do you have an AC panel on the boat? or the wires just go directly in and out them the freedom? do you plug
into 30a or 15a?
the freedom should have it's own battery switch from the battery not using the house loads swtich.
does the freedom have an echocharger cable? otherwise it's not charging the engine battery. (actually it is through the alt cable LOL....)
this whole thing was wired by someone smart enough to get himself into trouble but not smart enough to do it right.
I just noticed also that if you turn all battery swtiches off you will still have DC boat power comming from the engine battery... maybe you've missed drawn it. or maybe it's just really bad...
