AGM to Lithium in 2022 Sanctuary

[The Rookie]

G

Wire the 12 V A/C to the HOUSE BATTERIES. The inverter isn't even a concern.
While the house batteries are being charged by the converter while on SP or genny, the converter is probably only rated at 55 amps. So the batteries' SOC will go down.

Got it thanks.

Yespecially.

How much? Those 300ah NewtiPower were selling for $327 on Amazon. Not an automotive battery if you have that requirement?

Yes I will cancel & order for coach.
Need to figure out combining wires to 1 battery

These 2

These 2 are there. Look the same?
Same price.

Great. The small volume 300 lit seems newer and ships from newtipower will get

I bought that battery last year, it has been awesome, it is a mini size 300ah, so check the dimensions to ensure you are ordering the smallest 300ah they have. I did have to do some rewiring because I did not have to wire in parallel anymore. It is actually simpler to wire with one battery, but it is possible you may need extension cables? Just get good pictures BEFORE identity your main positive cable and main negative and put the other connector cables in storage. Create you a thread on your journey so you can post pictures to get help. If I add a 2nd one, I will buy or make some cables to put back in parallel because the 2nd battery will be inside the RV. Unless I can run an AC 8 hours I will never need more than 300ah.

Well, DKoldman, you have piqued my interest on something. Please correct my thinking on this:
15k 120v A/C up front.
Add 12v A/C to the existing rear fan spot.
Wire 12V A/C through the existing inverter.
While connected to either SP or genny, I could turn the inverter on and run the 12V A/C from the batteries. These batteries are constantly being charged by the SP or genny.

Am I missing anything or are there any concerns?

The Ace has already explained the 12vdc AC does not need an Inverter.

It is a thought, and it is all about options. For $389 and $200 to my Mobile Tech; I could have 3 ACs and no worries

I could leave my roof tops intact with my 50 amp service and use the 12vc unit in a pinch. I got 3 ceiling air fans that I am sure someone could prove they technically do something, but they are pretty much useless. The one in the Kitchen would be a perfect candidate to replace with a 12vdc AC unit. Or by the time one of existing roof tops fail, they make a combo 120vac/ 12vdc that you flip a switch to use what you need.

Thanks for the info.

Perfect I created another thread.
Will put pictures there

Update: I decided to go with the Ecoflow Delta pro 3 with a second battery (total 8000wh or about 750ah). This unit can be charged with AC & DC, has pass through power, 12, 120, and 240 output. It is considered portable, however it does weigh 100 lbs. It has a 4000watt inverter but is capable of 5000watts and surging to 6000watts. I also purchased the car aux 800watt car/alternator charger and 500 watts of solar. I will be installing this in my B-van garage area but making it completely removable ... it will be plug and play. My plan is to install this after the transfer switch but before the fuse box making this an easy plug in system. This way it can be charged when plugged in to shore power as well as when my generator is on. I will continue to use the same converter even though I could use the 12V output. I will leave the AGM batteries in for now but will be adding a 12v charging option to the delta pro 3 as well as using the roof 200 watt solar and the 500watt portable solar when stationary.

I will then be making a similar plug and play station on my boat ... making this one system able to be used in either application. PLUS, I will use this for my home back-up power system as it can plug into my generator port ... giving me another use.

Still thinking about possible 12 volt conflicts in the van ... but I am getting close ...

I also went with a stand-alone portable solar generator and solar panel. Smaller than yours but upgradable. A 2400w system and 240w portable solar panel. Has a 30a plug so very easy to use for the RV. Will change from 0 to full in a little over an hour with 120v ac. Able to run the microwave now. Can do AC but not currently needed. Simpler upgrade. Can be used for RV, house or when working on the property. Cost was much less than a total RV system upgrade.

Wow, where there is a will there's a way. When done some pictures would be nice. I don't wish to pry, but it would be nice to know ballpark range of what this may cost? It reminds me of when I first join the forum and Lithium was all the rave, but it was no way I was going to spend $4k to get it. Then 5 years later, I got what I view as better Lithium conversion system for $500.

Hey I even have portable solar now. 1152wh Bluetti and 200 watt Solar Panel. It really wasn't for the RV, but I have Victron 75/15 Solar Controller that I rigged up with alligator clips so I can charge any type of battery I want anytime, anywhere, under the Sun, but it has been raining 80% of the time since I bought

This is what I have done, I caught a Memorial Day promo with Bluetti, I actually bought 4 of the AC180s, one for my mom, two kids, and for myself. I only bought one 200 watt solar panel. So far so good, but that panel is only get 120 -150 watts in optimum sun so I need more time to evaluate.

If you know me ... you know I will be creating a video of the entire install and post it on my YouTube channel. I should get the system in about a week and the cost .... are you sitting down ... around $5700.00 for everything ... $4700 for the delta pro + another battery ... $500 for the solar panel, $400 for the DC charging system, and figure another $100 in other stuff. I should have the video out in July

I got my on sale as well this weekend ... but as I stated above, my plans are to tap into the electrical wire post transfer switch and add the input/output connections to that wire (literally male/female connection) .... this will enable easy plug and play + completely reversible.

Yes, I know you now, I was kinda of slow. I was wondering why posts above were referring to you as she. Now it all make since, you are not the average bear... he or she. I look forward to seeing even though we have a 30 footer, both of my brothers have Class Bs, but when do things they use my stuff

For around $500 I got a new Bluetti AC180 1152 watt power station and a 200 watt solar panel. No real need for solar just playing around to make the solar fanatics happy. But here is what I am thinking if I may do for fun.

I have two 125ah AGM vMax Tanks just sitting around. I may wire them together on a bench. Make a special cable with MC-4 to connect the batteries to the Bluetti DC input barrel cable. This would give me 3,000wh + 1152wh = 4,152wh if my math is right. Now, I wouldn't normally carry those 75lb each batteries around with me in RV all the time, but I could. But I would have 4 times more capacity at home without spending an extra penny. I have separate Victron 75/15 Solar Controller to re-charge the vMax tanks when needed. So far, I am only getting 120 - 150 watts peak from the 200 watt solar panels to recharge, but Bluetti says they will improve over time. I don't know about that, but it is not a worry for me right now.

Good job on the videos. My son is starting to do a few videos like that with various products. I tend to play too much so it would be very hard for me to do. Maybe if I ever retire. I just learned I have to work 2 years longer than I planned to get full retirement. I work too hard during the day and try to stay private, so the forums are good stress relief, plus I learn a lot.

Good luck with the project and thanks for what you do.
