Thanks for your help with this install. It sounds as though I can plug my shore power cord from my rv, into the 2000 watt inverter that I want to install. So 2000 watt inverter 250 amp inline fuse from battery bank positive term to inverter without charger. and turn off my installed converter and all other not needed power draws at the breaker.
The fuse size will be in the inverter's manual. Manuals vary by brand on how big a fuse you need. It might depend on whether they cover the surge watts or not. My Vector 2000w(4000w surge) inverter specifies:
-ANL fuse rating for direct hardware- 500
-Proper cable gauge(AWG) at 6 ft- 1/0
-proper cable gauge(AWG) at 10ft- 3/0
In real life, if you are certain you will never run the inverter to more than whatever watts, so it draws (divide by 10) so many DC amps from battery, then you can have a smaller fuse and wire. Supposing nobody else uses it! :( EG your microwave wants 1500w so that's 150a from battery.
Some brands specify a smaller fuse than that. Go with your own manual for your own inverter (manuals are often on-line if you want to read before buying to be sure it does what you want))
In actual fact my inverter like some others have (Cobra)has two pos and two neg terminals and you can get a wiring kit for it with four wires each three feet of #4 AWG fitted with 200a lugs. In that case you can put a half size ANL on each pos wire, or put one big ANL to the pos battery post and attach both pos wires to that.
The other type of inverter fuse besides ANL ( a T something?) costs more and needs a fuse holder which also costs some. You can also use a holder for an ANL if required.
You can get big amp ANLs at those car audio shops where they turn their cars into boom-boxes.
