RE: Automatic Transfer Switch

Gdetrailer, Nice choice of inverter/fridge. My Magnum has a standby mode--but ever few seconds it checks for a load. That causes the microwave to beep, as I run in a "whole house" mode.

RE: House Battery

I believe the person saying carrying the batteries ment for him even exchanging them. Some of us can not, nor should leave them in an RV during times of non use. Ie a storage lot, no 110 to trickle charge the batteries during say 6 months of non use. That's an 18-20+% discharge. So best to keep at home where it's warmer, and you can setup a trickle charger. Marty Warmer is the exact opposite of what is good for lead acid cells. Fully charge and disconnect. Or add a modest solar panel system. 5 watts per 100 amp-hours without a controller and a nominal 12 volt panel.

RE: Automatic Transfer Switch

Otherwise, if it is you simply do not like propane at all, swap the RV fridge for a home fridge conversion.. My current TT, we did a home fridge conversion, just one pair of 6V GC2 batteries powers everything we use including the fridge for 24hrs without the need for solar or a generator.. Gdetrailer, Do you know the make and model of the fridge?

RE: Automatic Transfer Switch

A combination Converter/Inverter with built in ATS would be nice but they are very expensive. I Strictly speaking hybrid inverter/chargers don't have an ATS--but rather a type of autoformer. They do have "pass through" capability, if used with the inverter off. Another possible route is to use double conversion. I often connect4ed just the converter on shore power. I ran the RV from a 2500 watt inverter (Cobra rated to run motors) $230.00 bucks. The convertor would recharge the batteries when demand was low. I still prefer a simple plug over an automatic transfer switch. After all--one has to turn all items off with an ATS before activating it. The difference is after unplugging from shore power, I plug into a female outlet in the "mouse hole". I'm certain what ever method works out for you that you will enjoy it. Prices on the inverter/chargers have dropped a fair bit. I think there are a couple that are under $1000.00.

RE: Automatic Transfer Switch

BFL13, I went the other route.I installed an outlet hard wired to the inverter which ends at a 30 amp female plug in the "mouse hole". There are bypass plugs for those occasions when GFi plugs cause the power to disconnect, too. That still leaves me with "extra" power from the inverter which has another inverter powered outlet in the kitchen.

RE: House Battery

I prefer the two 31 option. BUT as noted by one poster, carrying a 31 is too much. But they can carry a 24, so the three 24's if they fit in or on the battery tray, would be the better option for that person. Marty Why do the batteries need to be carried? Just leave them in place year round.

RE: physical size of solar panels

Perry, You are rarity. The wfco converters rarely get to a boost voltage. 21 volts may indicate an electrical failure inside the "box". To size my system, I used a 15 amp outlet and a kill-a-watt meter. I used the RV as I would for boondocking for six days and then averaged the daily consumption. That number multiplied by two told me battery bank size--and by extrapolation the watts of solar. I did do a "survey" of the devices, too, but I relied more on the six day average consumption.

another Bev RV

Hi all, Top range over 200 miles https://youtu.be/rlu7_dVxYh4

RE: Automatic Transfer Switch

My RV since 2009 has behaved as if it were always on shore power. I first used double conversion, but changed to a hybrid inverter/charger of 3000 watts. I'm told there is a type of autoformer in the inverter/charger. This eliminates the need of a transfer switch.

RE: physical size of solar panels

CA Traveler, 5 hours a day is the best one can do.

RE: Automatic Transfer Switch

Hi, I chose to move to an inverter/charger with load support. It does have pass through and if shore power fails when I have the inverter on there is no time delay at all. ATS devices that switch under load tend to not last too long as the contacts burn.

physical size of solar panels

Hi All, Maybe useful? https://dakotalithium.com/2020/07/10/solar-panel-size-chart-for-rvs-vans-campers/

RE: Not solar again ?

Hi, If you disconnect the panels from the charge controller no damage occurs. If you disconnect the battery bank from the controller there is a good chance of letting the magic blue smoke out of the controller.

RE: Small dryer in Minnie Winnie 25b basement.

I would have a brace welded in place. I'd line the bottom with 5/8" plywood. What is there is unsafe.

RE: Surge Protector

I always check the voltage under load before I plug in. How do you check under load before you plug in Unless you have load cell? Ken Since I am in a 30 amp RV, I made a 30 amp to 20 amp box, with 4 outlets. That allows me to plug in two high draw items. For example a hair drier, or the like. I plug in a kill-o-watt meter set for voltage. in another of the 4 outlets.

RE: Rivian towing efficiency

Grover, I think it may be the square of the voltage--not "power". Example 120 x 120 = 14,400 100 x 100 = 10,000 10,000 / 14,400 = 69% So a 31% drop in wattage. . The voltage of a lithium ion battery is essentially fixed for any given vehicle. Since power is volts times amps and voltage is fixed the amps vary with power. So the I squared R losses do apply. Afraid not. There may be less voltage drop--but there is still some.

RE: Generators: Cummins 4500 vs Westinghouse vs. ?????

I would do twin Champion 3400 watt with remote electric start. I'd add a hybrid inverter/charger with load support. Or twin Predator 3500 watt units--but there is no remote electric start.
