I'm confused. I've read loads, possibly too much and am puzzled...
I have an inverter (battery?), domestic batteries and a Victron Multiplus (and an engine battery).
I've been told when cruising to leave all red battery switches on (the big ones) - no problem with that, everything is fine. If I want to charge my mobile when I've stopped the engine, I also turn a big white switch which sits under the Multiplus to 'on' and it works - my phone charges. I then turn the big white switch off unless I want to use 240v (?) for something else (unlikely).
I don't know if this is right or wrong but it works.
I also have a Multicontrol which is 'on' 'off' or 'charger only' which is turned off most of the time. This I'm fairly sure I turn to 'on' to charge phone as above.
I don't know if this is right or wrong.
So my first question is am I doing anything right or everything wrong?!?
I'm presently moored in a marina en-route to Berkshire and when I was hooked up to the shoreline I was helped by someone and he turned my inverter battery switch to off and moved the Mulitcontrol to 'on'.
As far as I can remember, the big white switch was turned to 'on' also.
So I dried my hair last night with a hairdryer (a sin I know and I will go to hell) and red lights went on the Multicontrol to say 'low power' and 'overload' so I moved the switch to 'charger only' and it worked again (my hairdryer).
I'm worried that I'm doing things wrong and not doing my batteries any good at all and would really appreciate some help.
I have, as I said, read lots, have manuals etc. but I really struggle with them, as if they're written in a different language.
I understand the principles of electricity but guess as I am more creative than anything, this could explain my frustrations and lack of understanding.
Any help would be greatly appreciated as I'm more than a little lost.
I have searched loads but nothing seems specific to my questions.
Thank you all for your patience!
