I’m from Lahaina Maui and I lost my home. I purchased the Cherokee Timberwolf 16 ML trailer ,I’m gonna live in it. It’s gonna have to be off the grid because it’s no power so I haven’t received it and I was trying to plan ahead and also try to understand the best possible approach for battery, power solar, so I’m gonna get a 48 V hundred amp battery. I’m trying to figure out the all in one inverter charger and how many 200 W panels I need now it comes with a TV which I’d like to use a refrigerator everchill model SRM – 4186B – C it says it uses 480 KWH yearly which needs to be on 24 seven to be able to use the microwave from time to time , and maybe the air conditioner too it’s a Furrion model FACR15HESA – BL – a.m. 15,000 BTU. I think it’s 1730 W 15.8 amp cooling It comes with a fireplace which I will not use and it comes with a washer and dryer which I will not use a dishwasher which I will not use an icemaker. Maybe I don’t know how many LED lights and all the other power consumption needed , it’s a propane stove I believe and also propane hot water on demand so I’m trying to figure out the power consumption and the company is not being too helpful in giving me that information and it’s a 50 amp plug it says 120/240 and I wanna make sure I get the right power inverter and I guess I’m one of the few people that have purchased a Timberwolf 16 ML I don’t have too much friends communicate to communicate with so my puzzle is what’s a nice power solar inverter all in one, thank you everyone for your help so if you could share with me, what’s the best all in one inverter and how many 200 W panels I need I live in Hawaii. It’s sunny all the time again thank you for your time🙏🏻🤙🏼

Sorry to hear you were part of the Lahaina tragedy. Best wishes moving forward.

get a 48 V hundred amp battery.
Lets get started using the correct units:
48V and 100 ah hours.
48V batteries are 51.2V nominal (the median voltage of the battery)
51.2V x 100Ah = 5120Wh

Lets say you get 5h of usable sun each day:


Screen Shot 2024-04-20 at 7.34.07 PM.png

5120Wh battery / 5h solar = 1024W of solar to recharge from empty
This is assuming lithium, lead acid 50% dischargeable so capacity is 2560Wh

refrigerator everchill model SRM – 4186B – C it says it uses 480 KWH yearly
480,000Wh yearly / 365 days = 1315Wh each day

Add up all your daily usage in terms of watt hours (Wh) and we can size your system.
 
Thank you so much now do you know an all-in-one power inverter that I can then make an outlet power box connected to it? and then I can run the plug from from the box that’s connected to the inverter to the side of my RV, again thank you so much for your help. If it’s on Amazon it’s even better shipping out here sucks
 
Yeah, that’s my problem. I’m trying to figure it out, but the company does not really have a consumption information as I wrote above. Those are the model numbers for the air conditioner refrigerator, microwave is a 900 W power 9.5 A made by contour it does come with one of those fireplaces that are electric and a dishwasher with small portable ones and they all in one washer and dryer. I’m not gonna use the dishwasher or the washer and dryer. I’m not gonna use the fireplace. It does have a inverter in there somewhere that takes, the power and charges the 12 V battery that I’m assuming runs the 12 V water pump the LED lights.. and lastly, it has a TV it says 110 W/0.5 standby I would like to have TV. And on the other side of the coin, I don’t understand the power outlet it says.120/240 I put a picture on the beginning of the thread, but the power inverter that I get confused. Is it 120 or 240? I’m trying to get everything off of Amazon because shipping out to Hawaii is impossible but if you have other suggestions maybe the top three I’ll share with you the ones that I’m looking at and you can tell me if I am, OK with that? And if it’s a little overkill that’s fine. That means if I get more batteries, I could then use those other appliances if I wanted to maybe
First of all, thank you so much for getting back to me. I understand it’s difficult to do things online. I’ve tried to go to Solar companies on my island, but they’re not interested in RVs. Because of the fires RVs are now starting to show up here but they were frowned upon And not really accepted,but now because there’s no housing they’re starting to come in but solar companies don’t want to get involved so your kind of on your own…so any insight I’d be much appreciated. Let me know your thoughts of the two that I showed you

I put a picture on the beginning of the thread, but the power inverter that I get confused. Is it 120 or 240?
It can be setup as either. Single is 120V output. Split is 120V x 2 with each leg in a different phase (common household 240V). It sounds like your trailer is setup to provide 240V and possibly setup to plug into a 240V "50A" shore power supply.

Sounds like you have a lot of energy users. You need to figure out the watts each uses and the number of hours per day you want to power them. You system is sized based on this,

If you provide list of what you expect to power with info, we might be able to figure out the watts but you need to specify how many hours per day.
 
You could go at this by sizing a system to max out the 50amp RV plug. 50a at 240vAC is 12,000w (6000w per leg). That is the max your RV is able to handle for things that are inside it. This approach gives you a upward bound on what you can do. It also lets you decide that you can live with less if the costs of achieving it is too high.

Most folks will try to add up the things they wish to power and than selectively turn them on and off so as to live with a smaller setup. To add up what something needs to operate you need to know its running watts (or amps at voltage) and length of time it runs. Say you run a 1200W toaster for 10 minutes. 1200W X 10min X 1hr/60min=200Wh of energy used. Without loss that would take a 200w solar panel 1 hour in full sun to accomplish.

Solar panels rarely deliver their watt rating. However it is a useful number to use with a sunny days average for location. Say your location has an average sun production number for April of 5.5 hours. This means over the entire day of sun up til sun down your panel will average out like it was producing its rating for those hours (Ex: 200w panel would give you 5.5h X 200W=1100Wh.

All of this is why just buying things and hoping it will work can be a problem. Knowing what you want to power and for how long is essential to any design. I am sure it seems overwhelming but there are tools both on this Forum and on the 'net for sizing a setup that allows you to enter things you intend to power. A short run down of this is here: https://unboundsolar.com/blog/sizing-off-grid-solar-system

Ok this is all I know it has. I will try to send a YouTube video and might give more insight and once again I can’t thank you enough. It has been a struggle over here. We’re all trying to figure out how to live in a town that is completely gone. I’ll be 60 in May, and this is a pretty good challenging life lesson so I’ve been on YouTube university trying to learn as much as possible. I am mechanically inclined. I know how to hook things up what I’m not smart as how to order the parts. I ordered the one battery because Hawaii does not get lithium batteries shipped to us I found one person that would sell batteries that weren’t three or four times what you could get on the mainline
#1 rooftop air conditioner furrion model face15hesa-bl-am 15000 btu,,,eer 7.1btu/w …volts 115/60hz/1ph. Power cooling 1730 watts amps cooling 15.8
#2 ever-chill refrigerator 15.0 cubic feet, model SRM – 4186B – C. 480kwh yearly
#3 contour microwave for RV I don’t have a model number. I’ll put a picture which I know doesn’t help. below.
#4 tv sansui model S55VAUG it’s a 55 inch TV. I’ll put the energy guide below.
#5 I know there will be power outlets. I just need to charge my phone also maybe a small rice cooker I know I can maybe not use the air conditioner and run something that requires more power and play that game also to help off set anything I can’t think of
#6 it comes with a bunch of LED lights which I’m sure are 12 V which if is plugged into power is being powered from the 12 V battery that comes with the trailer and I’m sure there is a power inverter there that converts 110 to 12 V to charge the battery don’t know how much that uses
#7 fireplace model FF305C155A – BL again. I will not use it to stay warm. It has some setting. I think maybe it just gives that picture of a fireplace that might be cool to see but if it’s getting crazy, I won’t use it. or again turn off air conditioner just to see it work for a minute or two.
#8 dishwasher by contour model number DW – 2295BK I’ll put the energy guide down below I will not use the dishwasher. I will wash dishes by hand. It has a 12 V pump for the water and propane on-demand water heater. Maybe it uses a power from 12 V. I don’t know.
#9 washer dryer combo from contour model number RV – WD900W again I will not use this at all because water is going to be difficult for me as they’ll be no water where I’m living. I’ll have to bring my known in so I’ll wash clothes somewhere else.
#10 it comes with a propane, gas stove oven. I don’t know if it uses electricity for lights on the panel and I have no information except what’s in the video that I’ll put below.
#11 it comes with a contour portable icemaker. I don’t know anything about it, and I probably won’t use it to save electricity.
I think that’s pretty much about it on appliances. Now it has Bluetooth capability for speakers and a bunch of power gauges to tell you your water tank is empty. I think that’s all 12 V which is on the video in the wall in the bathroom. There’s like a circuit panel power inverter I think and that’s about it.
This is a link to the video. I hope it works.

Again, I can’t thank you enough. So my next step is getting the all one power inverter I’ve been getting most of my infofrom Amazon as shipping is a bich but if it’s not on there and you think the one you recommend is better, I’ll pay for the shipping. I’m not particular on any brand so I’ll lean on your expertise. I can go a little bigger for future power add-ons like coffee maker or whatever little appliances I can also get a second 48 V hundred amp battery, i’m not planning on hooking it up to the grid but maybe in the future or using a generator to charge if I did it. I was thinking about getting 4 or 5 those flexible 200 W solar panels by bougerv maybe if I need to add more I am able to do that
So my next puzzle is the all in one power inverter that could accept that much Solar and put out enough power to run the refrigerator 24 seven and the TV I’ll just say five hours when it comes to the air condition let’s just say five hours on the microwave Let’s just say 15 minutes daily?
I hope I wasn’t a pain in the ass and again thank you so much. There’s no one really over here that I know of and I’m trying to reach out to help solve this puzzle.🙏🏻🙏🏻🤙🏼

Thank you for your help I don’t know how this forum works. When I reply. Do you only read the reply I gave to you or can other people read the reply anyway I’ve been replying to somebody on the form that’s been helping me you’re able to read it …that’s great thank you for sharing your knowledge. I have written that down.

With the exception if a person is placed on "Ignore" by an individual and that is blocked from view of the person who wants to ignore that poster. Mister Sandals is not my ignore list so I did see his posts to you. I was not trying to horn in on his help but just giving some basics to help you in coming to grips with how to setup an off grid solar power supply.

One piece of advice after you do all your calculations is to allow for how much power is used by the system to make the power your appliances eventually sees. For instance an AIO may have an idle power usage of 60-70w. This is all the time and can eat a surprising amount of energy. 60w 24h/day= 1440Wh.

That’s cool so I don’t have to repeat all the things I said to someone else I take all advice into account and again I can’t thank everyone enough for the support. It’s pretty amazing so now I’m trying to figure out the all-in-one power converter.
