Renogy 3000 watt inverter/charger

@satek60 posted:

Initially our inverter was in pass thru, batteries were o tounge. Now upsized 2kw inverter and LFP batteries are under bed. The ATS is behind the breaker panel in the galley. The inverter is switched on via the remote by the door The Inverter feeds the ATS through a 12-3 SO cord running under the trailer alongside the frame. I like the painless auto transfer feeding all the 120 volt appliances. Of course the converter breaker must be off when on inverter.

1500 watt inverter under bed (ipgraded 2000watt in same location) remote mounted below fold down table in background.

Almost finished  install

This is pretty close to what I was thinking my install would look like.  My two BB batteries are already under the bed, and I was going to add two additional BB batteries, Renogy Inverter (with Bluetooth), and Lynx Distributor.

My AC cable from the Renogy Inverter will exit out the under-bed storage area through the pass through, then down under following the chassis, and then upwards through the floor opening to the ATS switch and breaker panel. 

Like you I was thinking of adding the ATS behind my breaker panel.  I have to look at the space there, as everything is so tight.  What is a 12-0 SO cord?  I know this cord supplies the AC power, but did not know what type of cord you were referring too. 

Thanks for the pictures and description.

You should consider individually fusing those batteries.

I have bought two, but they are pretty cheap, and is something I should do for "just in case".  I have 300Amp fuses, unless I should consider 150 AMP.

Thanks

Size you nain semi conductor DC fuses for your largest single use. If not the AC, then microwave, toaster, coffee maker, hair dryer etc.Using a semi conductor DC fuse means it clears based on current rise time, not current alone. That's why they are so expensive. Think of them as safety devices. I have 150 amp Eaton Amptrap fuses (2 because I doubled up my cables and havev2 main disconnects as well) which can handle the AC, my single largest load.

Stay safe!

I was sizing my DC fuses in case I want to use the AC, which does have soft-start attached.  What I see  us using most often are the Microwave and our toaster.  Our Norcold gas frig was working well at the end of last year, so hopefully we will not be needing to switch to an electric compressor right now.

I also have to admit I think  part of the reason I want to install the Inverter is partly to say I have accomplished the installation and it does work.

SO is 12AWG wire 3 conductor cable . The black jacketed extension cord.

These are the common cords you'll find.

S cord = Service cord

SJ =  + Junior (thinner jacketing)

SJO=  + oil resistant jacket

SJOO = + oil resistant inner and outer jacket

SJOOW = + water resistant

SJOOWT = + thermoset plastic

--Or any combinations of this alphabet soup.

To add to the confusion--

A 12-3 S-cord  (a cord) has 2 conductors + an equipment grounding conductor. (white, black, green)

A 12-3 Romex (a cable) has 3 conductors + an equipment grounding conductor.(white, black, red, bare or green)

I had no idea of these abbreviations for electrical wire. I have some existing AC wire I had used to wire electrical sockets in my basement but I am not at home to see the type it is. For AC wire which will run under the trailer chassis which would mean it could get wet, is there a specific type of AC wire to use in this situation?

thanks

Yes, one. Of the SO types. They have stranded wire, unlike Romex which is solid.

Home Depot and Lowe's have it on both large spools which are cut to length, as well as pre cut packages of various lengths.

When I get back home I will check the type of wire I have on a spool. I believe it is solid copper wire but will need to verify. Thanks for the insight here. By the time I learn most of the important aspects of RV electrical system I may too old to camp anymore.

This is the 10/3 SOOW that I used last time.

WindyNation 25 Feet 10/3 10 AWG SOOW SO Cable Cord Wire - 10 Gauge 3 Conductor 600V Portable Power Extension Cord Cable for EV Chargers, Motor Leads, Portable Lights, and Battery Chargers: Amazon.com: Tools & Home Improvement

I don't remember now why, but the SOOW that I have used in the past, from Home Depot, was preferable to the wire that I ordered from Amazon/Windy Nation. Something about the jacket being a pain to strip from the Amazon wire maybe.

Lowes sells it by the foot, 10% off with Veterans discount (I also bought the AIMS inverter there a couple years back). Chose it because it is stranded copper, durable jacket and cheaper than Marine wire which is what I normally use. When relocating to the under bed location I simply rerouted it and cut it back. Here's a cut sheet on SOOW.
