Inverter upgrade question
Posted: Wed Mar 13, 2019 1:57 pm
Hey folks,
We have a 2003 24RB. Factory installed is a simple Cobra inverter 300W. What I can tell there is a single power line coming off it.... that goes to the outlet by the TV (next to the fridge)... I also know this feeds a second outlet in the over cab bed area under the bed.
I am going to upgrade my inverter to a 2000W Pure Sine. Why? Just to have a little more flexibility - I wish to add 2 more outlets off this inverter - TV, New outlet and another new outlet. For 90% of the time we won't need this kind of capacity... but I wanted to be able to run a toaster or coffee machine, maybe a hair dryer.
As an FYI - this is part of a larger set of upgrades I am working on:

I have done a lot of reading and research but electrical is not an area I have a lot of experience. For folks out there with more experience, please let me know if I am missing a key step or concept. Here is what I know and plan to do:
As for the current inverter wires... they are 10 gauge with 30 AMP fuse - I plan to re-use this wiring. Last year we upgraded our refrigerator to a newer Norcold 3 way - but I had a 2 way before, so my current 5 AMP fuse and current DC wiring to the refrigerator is not thick enough. I have a length of 10 gauge wire to run up and over to the refrigerator. I figure I would save myself some time and splice this wire run to my existing 10 gauge on the old inverter... fuse is all set I just need to get the run to the back of the refrigerator. Since I installed the refrigerator last year, I think I will just pull it out again.. and drill a hole in the wall into the cabinet (above TV) near where the existing wire comes in and then travels over the roll bar to the power center by the sink.
Ok, poke holes... what am I missing or what do I clearly not understand about how things are wired. Thanks! I love all the knowledge here in the forum... and I am still sad BF closed, at least I had a chance to visit the factory in 2016, meet Kim and tour the place.

As an FYI - this is part of a larger set of upgrades I am working on:
- A) I am replacing my single stage Parallax 7344 Converter/Controller to a Progressive Dynamics 4655VL
- B) I am also upgrading my house batteries to 2 x Trojan T-105 6 Volt Batteries

I have done a lot of reading and research but electrical is not an area I have a lot of experience. For folks out there with more experience, please let me know if I am missing a key step or concept. Here is what I know and plan to do:
- 1) I have removed the current inverter. This is fed by 10 Gauge Wire. I assume this wire goes back to the battery? And I know there is a fuse for this as well. My inverter fuse is located on a small block outside the main electrical unit - right by our water tank.
- 2) I plan to install the inverter in the same general place... under sink area - on the opposite side of the wall that houses the water pump. There appears to be room here and the current TV outlet is wired to right here.
- 3) The new inverter needs BIG wire. My plan is to run 2 gauge wire with a 225 amp fuse directly back to the batteries (recommended by inverter manufacture). I was going to drill a new hole in the floor near where the current power feed comes in the floor and run the 2 gauge wire (red positive and black negative) back to the batteries.
