    Cost of solar

    Boy Howdy... my first year of full-timing I relied on generators. I was noisy. I did not like it. Now, I run them to exercise them.

    Why the laser focus on Idle Power?

    The Nut If you have a small system with light loads, Idle power consumption is a concern. The amount it needs to stay on 24/7 in significant in percentage. If you have a large system that is on all of the time, it is not a huge concern. You are using power to run the system all the time anyway...

    Why the laser focus on Idle Power?

    Idle Power... why the obsession? How many hours a day is your system idle? On a very small system, sure, it makes a difference. In a whole house or a system that is powering stuff 24/7 idle power means nothing... what should be noted is power consumption under load if that is what the system is...

    Cost of solar

    Mine was designed by the Germans..... so that refutes that one.... My system sucks about 70watts at idle, but considering the size and consumption of my system, it is a drop in the bucket and inconsequential... Oh and my system is running 24/7 so there is no idle time..... next! ..and...

    See my previous comment of using 3500 watt hours a day.

    Cost of solar

    Because you don't live in an RV and do not understand consumption options therein? I suck up around 3500 watt hours a day, and that excludes A/C.

    Cost of solar

    Again.... there is a ton of trash talk about AIOs that are indeed all made in China. Now can we discuss where Victron is made? Oh , hey, China, Malaysia and India.... So AIO are cheap junk and Victron is perfect.?? My point is that there is a TON of trash talk that AIOs are junk, but I have...

    Cost of solar

    Ditch the blue stuff. Buy an AIO inverter controller, one affordable box to replace all the blue stuff. Build your own battery. You obviously have the skill to design a solar system, so, build a battery. Buy used panels from someone like Santan Solar. I built a 48v 280Ah battery and combined...

    RV 48V to power 12v Loads

    I have this in place. below is a diagram of the system (not final design). I used a Victron 48/12 converter. It prevents back flow of voltage. Note I have left a 12v battery in line so as to not hammer the converter and it give run time if/when I need to shut own the 48v.

    build my own for my RV or buy new lifepo4 batteries.

    I think you could fit 304ah cells. I lined bottom and sides with closed cell neoprene. I bought a scratch and dent model for $112. (edit - I built this in place as it weighed a crap ton... 250#++) https://www.amazon.com/gp/product/B001SF83F0/ref=ppx_yo_dt_b_asin_title_o09_s02?ie=UTF8&psc=1

    build my own for my RV or buy new lifepo4 batteries.

    The bigger you build the more advantageous it is to DYI. I built a 15kw 280ah 48v battery, all in with BMS and case for $3k about 2 years ago. I could could build it now for around $2400 because cell prices have dropped a lot. Two 300ah 12v? Buy them.

    12v Lithium to replace 12v LA-Deep in RV with constant feed from 48->12 Converter

    It is a Victron Orion-Tr IP43 48/12-Volt 30 amp https://www.victronenergy.com/dc-dc-converters/orion-tr-dc-dc-converters-isolated Yes it is adjustable, so the question remains, what is the ideal float level in this situation. I will fully charge the new 12v lion and then balance the cells...

    12v Lithium to replace 12v LA-Deep in RV with constant feed from 48->12 Converter

    (edit - the load on the 12v systems is very light 98% of the time just running lights, fans and the controllers for fridge/furnace/H2O heater )

    12v Lithium to replace 12v LA-Deep in RV with constant feed from 48->12 Converter

    The current set up is a 48v Lithium battery feeding a 48v -> 12v converter that is connected 24/7/365 to a 12v deep cycle battery that feeds the entire 12v system(s) in my RV. The 12v battery is inline to act as a load buffer for when I use the high draw 12v systems IE the Hyd motor for the...

    All in one 48V System 3000 Watts

    While there is much talk of AIOs not being up to he job, in searching for good case studies, I just do not come up with much in terms of failures. The ones I have read are worded such that I don't trust them. No argument that Victron makes solid stuff... none at all. *IF* I had unlimited...

    Need help choosing 48v all-in-one

    One year in on a 48/3000 AIO - 1001 KWH hours solar in ... 591KWH grid in .. connected a 48v battery I built. (not final form - missing fuses and switches) The AIO is a Sigineer M4830NC. $900 at the time of purchase. Flawless operation. installed in a lower bay of my Class A RV (bench mode pic)

    5th Wheel 50AMP Build Advice

    Make sure the DC/DC 48/12 converter has enough amps behind it... I went with the 30amp Victron. I have a 12v deep cycle battery in line to act as a load buffer. I have slide motors/hyd jacks motors that such up to 45 amps. YMMV IANAL.

    Adding Solar to a Class A RV

    Here is a look at how I incorporated a new system into my RV. You might want to look at a 24 or 48 volt battery, for several reasons, including ditching the 4/0 cable.

    Upgrading RV solar, mismatched panels?

    An expensive option is to build a rack to elevate all panels above the vents and AC. That is my long term goal. Right now I was able to squeeze 6 230w panels on my 32' In your case I think I would consider a different controller for the new panels and mount as many as you can. g'luck.

    Best system for RV

    I have an AIO, It runs a load 24/7, so it is never in standby mode, but when it does it idles at 50w and that bumps up to 70-90w .... with my starlink running the battery sees a load between 120-145w. The Starlink uses 35-70w Sigineer M4830NC 48v 3kw

    Upgrading to lithium/solar on a class c motorhome

    I converted my Class A to a lithium system... there is a fair amount to it, and you should dig into the systems in your coach. You can leave everything in the coach running as it is... IOW, the coach will not know anything is different, but there is "a lot to it", especially if you are not well...

    48v Lifepo4 pack charge 12v lead acid

    I have a setup in my RV where I use a Victron 4812/30 converter connected to a 12v deep cycle to power the 12v side of my RV. I have it currently set to 12.9v, but am considering upping that to 13.3v

    What is the most common RV battery solution? Self-built OR Vendor Assembled?

    I built a 48v 16 x 280 battery, using a jobsite toolbox, closed cell neoprene and a Overkill 16s BMS. All in was $3k. If the goal is a big battery, economics still favors a self built, but it is getting very close. My cells were $160 each in March of '22. I checked last month and they were down...

    Couple questions if I may for future full-timing

    With that much solar and 15kw of battery you should/could be looking at a 48 volt system.
