I need to connect a Victron Multiplus Inverter/Charger to my batteries.
The manual says wire it through a switch and a fuse to the batteries.
Their wiring diagrams show it wired straight to the batteries.
The unit itself has a large fuse in it so why do I need another one? Is that just to protect the cable between the batteries and the Victron? All 4ft of it?
The Victron gives a healthy spark when you connect it to the battery poles, even when switched off, so presumably it contains a capacitor device across its inputs. I don't like the idea of leaving such a thing live when I am off the boat as I've had capacitory things fail before at home. So I should have a switch in the circuit, but then I understand that that would not be a good thing from the charging point of view as every extra resistance is bad news.
Finally I have the nasty battery isolator switches with the red fall-off-at-the-most-inconvenient-moment handles and the suppliers leaflet tells you everything except their maximum load. Could an inverter overload it (a general question as I've not given full details)?
So, how should I wire it please? And how do you do it (If different!)
