That switch is the piece of hardware you need. The transfer switch you posted only covers 15A though. I am ordering a 30A like this:
Go Power! TS-30 30 Amp Automatic Transfer Switch https://www.amazon.com/dp/B00153EYTO/ref=cm_sw_r_cp_api_glt_fabc_TH2ME23F6FHJ228TSAM4?_encoding=UTF8&psc=1
You will need to run a lead from your batteries to the transfer switch, through the charger, and from the shore power connection to the transfer switch. You also connect the inverter from the batteries to the switch. Then you run a lead from the switch to the distribution panel’s ac input. There is a wire diagram in the pictures on that Amazon link.
To get power from the inverter just cut the end off a sufficiently sized cord and wire that to the panel.
Hi,
I have not bought anything yet so this looks like a good potential option. I drew up a diagram of what I was thinking but don't know how to attach it here as a file (first time posting on Reddit).
This is the concept I am going for minus the alternator charging part:
These are the components I am considering:
Panels: x3 Renogy 100w 12v https://www.amazon.com/dp/B07GF5JY35?tag=skooliesupply-20&linkCode=ogi&th=1
Combiner Box: Eco-worthly 4 string https://www.amazon.com/dp/B07F5HDP2W?tag=skooliesupply-20&linkCode=ogi&th=1&psc=1
Solar Charge Controller: Renogy 40 amp 12v mppt https://www.amazon.com/dp/B01MSYGZGI?tag=skooliesupply-20&linkCode=ogi&th=1&psc=1
Battery: Chins 300ah Lithium https://www.amazon.com/CHINS-LiFePO4-Battery-2000-5000-Off-Grid/dp/B08N53GF81/ref=cm_cr_arp_d_product_top?ie=UTF8
Inverter: 2000w TBD
Shore Power Plug: 30amp
Auto Transfer Switch: 30amp in 30amp out https://www.amazon.com/dp/B00153EYTO?tag=skooliesupply-20&linkCode=ogi&th=1&psc=1
Converter/smart charger: Powermax PM4 60a 110v to 12v DC with smart battery charger https://www.amazon.com/PowerMax-PM4-100A-Converter-Battery/dp/B01ER3LGYY/ref=as_li_ss_tl?th=1&linkCode=ll1&tag=vc-electrical-20&linkId=d8548aa852a41b8ce022d573b5e907c1&language=en_US
Would this system all work together? Would that item you recommended be a better fit. I'm also considering getting a renogy inverter/charger/converter combo to do my inverting to AC from DC battery and also my converting from AC shore power to DC to charge battery but those are a bit pricey.
Open to all thoughts and recommendations of course.
which doesn't really work b/c my batteries are on the front of the trailer, so my inverter needs to be installed in the front basement of the RV, but the panel is in the aft portion of the RV - about 10 feet behind the basement.
Look at this as well: https://www.amazon.com/Go-Power-TS-30-Automatic-Transfer/dp/B00153EYTO/ref=sr_1_2?dchild=1&keywords=RV+transfer+switches&qid=1619885036&s=automotive&sr=1-2
if you are DIY inclined this is a very easy install:
You can get a 1000w inverter for less than $150, and a changeover shore power switch for less than $100. All of this wires in to the same cubby where your converter is, assuming you have space for them. Other than that you need about 10' of extension cord.
Shore power switch goes in between the outside plug and the power converter. Solar charge controller hooks to it too. Cut the male end and 2' of the extension cord off. It plugs into the inverter and to the last spot on the shore power switch. The battery connection runs to the inverter. This setup allows the camper to auto switch depending on if it is sensing power from outside at 120v. If it does it switches over to protect the inverter and wiring. if it doesn't, it will power the power distribution center from the inverter and batteries.
I did that from memory so don't use it as install instructions. I just wanted to highlight that it is not a very in-depth process. and as long as you don't try to install it with the shore power or batteries connected it is very safe. This setup would charge phones and run a TV. If you have a microwave it will depend on the power level. You might go to a 2000w inverter to be safe.
I would consider upgrading your batteries if you are still running on the stock marine battery it probably came with. I would go with a pair or two of GC2 golf cart batteries if you have the weight allowance and space. They are very effective for their price. If you cannot afford that in weight you can spend money and go lithium. I would shoot for 200-400Ah to go for a full weekend depending on your use.
edit: some links
1500w inverter: https://www.amazon.com/dp/B01COA0UTE?ref_=cm_sw_r_cp_ud_dp_36TZVH3CCSXQ372S48GK
shore power switch: https://www.amazon.com/dp/B00153EYTO?ref_=cm_sw_r_cp_ud_dp_XK6DJZBNK9ZTV3AG800K
Those together are about $375 shipped. You can find better deals if you want. I would ask what the dealer is actually installing. This setup would power all the outlets in the camper though, so I would say $3000 is very high.
