  1. Being "released" this summer 18k, 15k, 8k but roof mounted inverter compresser AC. They say the 18k btu will run off a 1000w inverter or a 2200w generator https://diysolarforum.com/threads/new-inverter-airconditioner-for-rv.80677/
  2. 50 amp to 30 amp adapter....https://www.ebay.com/itm/275119763163?itmmeta=01HRW3HARJ18E2T4B8TQG0PXFD&hash=item400e6a6edb:g:g3YAAOSw2ghh5YBc&itmprp=enc%3AAQAIAAAA8LCjTc19L78jYyjnWxPB44yi%2FbA4l9jsLTgRlx4SIEQ9wFaIp%2F8mXA0C%2FExfpC8sDVoRP8Xhn4eyzZHXM5D%2BQ2WO5o%2F4h9OhZXDy%2FgNgfVa%2FfMIcMROUWN3NCN1VYwwH6pIxUYkX1Qu3R1Mo%2B5yDwCRtXbe8OqtYKB6vHsawd3MZxBDgow09SFkI7pPAvmHq6%2FSEZH5u38qrZeeKIDQzqllJIRU7FKgKNAfaLRZ4VanmIYOWUzjj4kpUfbHmMVFHyIP%2F0ygzOclE%2FuMIkjhR9Fi6M7Vdo%2FjRH1BIt5mSQ4HfIyyHZSBstGJ9FoR2ROcu2g%3D%3D%7Ctkp%3ABk9SR8isxYPHYw
  3. Demms some bright lights. OK back to solar and some rambling thoughts 1. Install 3 AGMs 2 for house and 1 for engine, then your good to go 2. LFP is NOT a starter battery. You need a regular car battery or an AGM starter battery. 3. Your old 12v RV converter will charge a LFP to about an 80% SOC (state of charge). As an idea 2 of the 100 amp LFP batteries at 80% will have about 150% more energy than the battery you had. Depending when you park for the day, your solar may top off the battery before the end of the day Also remember as your driving down the road your roof mounted solar panels are working. 4. The problem with LFP and a stock alternator is that the LFP has a very low internal resistance. The LiTime battery will easily accept a 90 amp charge. 2 of them means a 180 amp charge rate. How long do you think a stock Toyota alternator of 60 amps will last at full power before it melts? The way the BMS inside of each battery (battery management System, with its controlling computer) works is if the battery is 90% DOD then it gets charged at 90 amps, if the battery is 50% DOD it gets charged at 90 amps, if its 25% DOD it gets 90 amps, if its 5% DOD then it gets 5 amps. 5. The DC2DC charger will let you set the MAX input amps from the alternator, then it talks to the BMS in the LFP batteries and divides the MAX input you selected, between the 2 batteries. So a 30 amp max input gets divided and each battery gets a 15 amp charge when your driving. So when your driving each battery would get 15 amps from the DC2DC and 5 amps from the solar panels. TMI... got room for a single 200 AH LFP battery, 21"x9"x8.5"?? There are a few with blu-tooth, low temp cut off,and self heating that run about $625 and would greatly simplify the wiring and the cost of the wires. You understand that your talking about 4/0 AWG sized wires for this much power. Without the bells and whistles a 12v 200 ah battery is under $500 You need to size the wire and fuses according to the batteries potential power, not how much you think your going to be using. You will always figure a way to use the extra power with some new widjet This is the boring part of designing a solar system. You should do a power audit, how much power each item uses and how many hours or minutes it runs in a day. Add it all up in watt hours or amp hours but not both mixed up, apple and oranges stuff. You may not need 200 AH of batteries. FWIW I been doing RV solar for 25 years, my first system was a used 60 w panel, a 15 amp controller and a Wal Mart Marine Deep Cycle GP 27 battery. It cost more than your 3 panel system. will. BUT it worked within its limits. Our winter boondocking time went from 2 days to 5 days before we ran out of power. Out of water after 5 days anyway so it was OK.
  4. Spring is springing, time to get your ducks in a row. Batteries... AGM 100ah Renogy is $190, weighs 65lbs, MAX safe Depth of discharge (DOD, going all techie) is 70%, they will work down to -4 deg, last 5-7 years, never needs water, can mount inside if you going out at -4 deg, works great with solar, Toyota alternator and your current 12v converter. LifePo4 (LFP) 100 ah , mid range $$ , a name brand-Litime, Redodo, is $230, weight 25lbs, MAX safe DOD is 100%, this maybe important to some the low temp cut off is 32 deg,...@ 80% DOD lifespan is 20 years, never needs water, can mount inside, works great with your solar, works so so with your factory 12v converter, Toyota factory alternators are not real happy. You need a DC to DC charger to protect the alternator. The LFP batteries are decreasing in price. Alternate LFP... the standard LFP100ah battery is between GP 24-27. There is now a mini 100ah LFP that is smaller than a GP 24 and weighs 19 lbs, cost is + $20. Also there LFP batteries that have low temp cut off built in, some even have heaters and blu tooth. There are +$60 depending which of the features you want
  5. If I read the Renogy web info right, you have a Renogy Adventure Li-30 PWM controller. With all the numbers running around the solar stuff, its easy to get things mixed up. The Adventure is a 30 AMP controller, that's the MAX amps OUTPUT it will send to your batteries. It's rated for a MAX of 50 volts, 400 watts INPUT from your solar panels. So using 3-100w panels in Parallel would be OK. NOTE a PWM controller is sensitive to miss matched panels, so make sure that your panels are the same, Voc and Isc. Those numbers should be on a label on the back of the panel. Amazon sells Renogy so you could get your extra panel there. P.S. easy up grade would be a 30 amp MPPT controller. They work differently and are in the range of 20% more efficient. P.P.S. A solar "day" is 5 hr, so under perfect conditions your setup w/ 3 panels will recharge about 65 AMP HOURS into your batteries a day.
  6. 100w Solar panels are cheap nowdays,like under $60. Hard mount your 2 over the sleeper and just buy another 1 of the same for your ground mount. Look up utube for pvc solar mounts. Use Anderson connectors for your extension.
  7. Super good for Chinook's' and good for all the other Toys needing A/C. https://velitcamping.com/products/velit-2000u-under-bench-air-conditioner-12v-24v?variant=45191899578605

    Oh, Yes

    Somebody on this forum, just absolutely needs this...https://bringatrailer.com/listing/1973-toyota-chinook/
  9. Well I guess we got Botted. We get some English as a second language people, just thought that it was book English. Well I guess it was.
  10. What she said. Easy solar, complete system, instillation instruction is available on the net. Starting here...https://www.mobile-solarpower.com/
  11. OK so your bored with "normal" camper vans... So how about an 1955 Alfa Romero Camper. To futher your "different drummer " lifestyle, its powered by a 2 cylinder, supercharged dieselšŸ¤© https://cars.bonhams.com/auction/29216/lot/110/1955-alfa-romeo-t10-autotutto-romeo-campervan-chassis-no-ar-t10-00314-engine-no-ar-1640-00252/#photos
  12. 1 vote for FRP, 15 colors.. 2nd choice would Formica, a lot more colors. Both are basically bullet proof.
  13. Take construction paper and tape it to the old window, mark it and cut to shape. The you can lay the pattern on the flat plexi and adjust the size to your plans.
  14. Welcome to the world of solar powered everything. Lots of folks want/need all the comforts of home all the time in their RV, think Glampers. If you "promise" no a/c, no microwave, no electric heater, there may be an alternative... https://www.licitti.com/product/acbatterybox/ Its a DIY solar generator, it comes with EVERYTHING you need for a LFP powered setup except the battery. Charger, pure sine inverter, 120v outlet, usb ports, 12v auto jack, MPPT solar controller. So with that and a 100ah battery, for a total of $500, you can have a "solar generator" that has 2x the total useable watt hours of the original Sunrader 12v system. Add $90 for a 100w solar panel and your all set to boondock. I have the 1000w unit with a 100ah LFP Redodo 100ah Mini battery, its the backup power for my wifes CPAP during power outages at home. Interesting LFP battery situation, there is a company named LiTime that used to be AmpereTime, they are selling all the NOS AmpereTime labled batteries at a deep discount. They also sell used inspected batteries, cheap. Mostly returns for physical size or capacity problems. Might be worth a look. I don't have one, but recently heard about them.https://www.litime.com/collections/12v-like-new-batteries
  15. Before WE can help you to build a system for your RV, WE need to know what you want to power. Its called an energy audit. Watts used x hours ran. FWIW I have a 1500w Panasonic inverter microwave and power it with a 2000w inverter, a friend has a TT with a 800w traditional microwave, it will NOT run using a 1500w inverter. A very useful cheap tool to use is a Kill a Watt meter. Its great for 120v ac loads.
