Thanks again everyone and happy holidays

You're welcome and happy holidays to you. Please report back when you get everything installed with pictures!!

Thanks to everyone on this forum, Your insight into my project makes me feel alot better, with this install. This will be the first time I will not have to start the gen, to make a cup of coffee in the early AM when my dog wakes me up to go out, and not wake up light sleepers. Thanks again everyone and happy holidays

I run my Prowatt just like you suggest. It works fine. Just be sure to turn off the big 120v loads, as you have said you will. Enjoy.

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.

Hi,

Yes, you can, but do try to keep the inverter as close as humanly possible to the battery bank without it being in the same compartment.

X2 And use the recommended wire size from the manufacturer too. Don't skimp. It's usually at least 2/0 or greater.

Hi,

If 2k is all you need prowatt gets my vote, too. $355.00 from bestconverters.com

Good bang for the $...

Prowatt

X2, gets great reviews too. People even use this in 24/7 use in off grid cabins.

I would suggest getting a smaller inverter for the VCR/TV?DVD player. Some where around 300 watts.
For the coffee pot we switched to a stove top unit for use while dry camping.
We do not use the micro wave much. In fact very seldom.
We use the genset for powering the microwave, electric coffee pot and toaster.
A different install would be to run separate circuit for you large inverter if you want to go that way. Install the inverter close to the batteries and run wire to your locations. Remember that the large inverter will have greater losses. Running entertainment system alone will have more losses then the system uses.
