I have recently acquired a pair of mastervolt inverters and a charger, second hand from someone who used them for an off grid workshop. They have nice fat wires with them.
I'd like to install one but even if I get someone qualified to install it, it would be nice to have a rudimentary understanding of how they work and what they do. Oh and what kit is really needed for them to work properly.
So please bear with and have some grace for the electrically illiterate.
batteries seem to be complicated, the holy grail being lithium, a level of holiness I one day aspire to. I have 2x mastervolt 100 ah batteries which seem to be nackered (they were a freebie with the kit above). numerous recovery cycles on the Noco genius haven't managed to get one above 10v under load and the other above flatline.
I also have an old car battery, 85 AH which is stop start compatible. Would this have the punch to run the inverter, which is a 1200w, powering an 800w microwave?
the blurb on the inverter suggests it could handle it, but reading several hundred threads about inverters and batteries suggests that the batt would not be able to keep up with the draw for any amount of time. (likely to be a couple of minutes reheating food). In my mind (remember it's dyslectric) I have the idea that I can have a separate system with the charger to the battery from the existing solar, and then a separate 3 pin socket to power the M/wave or toaster. this doesn't then have to be plumbed into the rest of the EHU system on the moho and I can just switch the inverter on and off when I want to use it.
What is a busbar?
What is bonded?
Do I need an inline fuse or not?
Is it worth getting the inverter wired into the EHU system?
MPPTs and RCDs are a mystery to me.
I've taken pics of what is currently there, to aid understanding but if you are kind enough to explain anything, please don't use any technical terms or jargon without explaining it. The last time I learned anything about electricity I was at high school and was certainly more interested in anything else than what the teacher was talking about!
