    Peer check on truck camper solar install

    Not exactly. Take an Odyssey AGM, for example: There is no limit to inrush amperage during the bulk charge phase (up to +/- 80% SoC)... that can be massive power. It's the *absorption* phase of charging lead acid AGM batteries that is the time sink. In some cases (per brand), four to six...

    Peer check on truck camper solar install

    If you don't have the panels yet, you might look at Newpowa's 210W panels. Dimensions are roughly 26.5" X 64.5" I was going to do four Renogy 100W monocrystalline panels (I already have two), but saw the Newpowa and thought that mounting two panels would be easier than mounting four... Having...

    Cargo Trailer 5x8 Overland Conversion - Cherokee XJ Content

    I just read two pages back in your thread here, to refresh my memory of your 12V setup. As long as you can stay on top of the battery voltage, you're going to be fine. That 1100 watt inverter is the most I would go with one battery. Do you have a transfer switch for your shore power (120V)? so...

    Building a fully enclosed Overland trailer to be towed by a Jeep

    Don't forget about white gas/camp fuel stoves. I have a selection of vintage Coleman pieces that I use to cook on.

    Thoughts on this trailer power system.

    Do you understand MPPT and how it works? It is of little to no benefit at 13 amps. Correction: I did see as I noted earlier (either here or in another thread) that when I was using a Morningstar MPPT Sunsaver and when I connected two 100 W Renogy monocrystalline panels in series I saw an...

    Thanks again, Rando. I appreciate the links. Tell me, though, why, in your opinion, is the Trimetric TM2030 "ancient" tech?

    Thanks Rando. I wouldn't know what those better options are, and the Trimetric has already been acquired, but not yet installed. It will be fine for what I'm doing, and no deeper than 50% is always the goal, even less DoD whenever possible. That said, I would be interested in reading anything...

    Thoughts on this trailer power system.

    Thank you Verskstad, Rando, Grassland. V, yes, Puekert's Law. Thank you for reminding me. d'oh! Certainly something to factor. Rando, they are Odysseys, and I'm glad you found that chart. I had been looking elsewhere on their site. If you go to the 30- [Edit: minute] amp load line, the wattage...

    Thoughts on this trailer power system.

    Let me start over... and thanks, Alloy, for getting me to think. :p Average of the appliance amperage is 11.5 amps @ 120V which translates, roughly, to 127 amps @ 12VDC totalling 30 mins run time. 30 mins = .5 hour | 127 amps X .5 = 63.5 Is that 63.5 amp hours' consumption of the a 100 Ah...

    Thoughts on this trailer power system.

    For the sake of easy math, let's say these 12VDC amp dumps are 150 amps each totalling 30 mins per *day*. What does that do to the 100 amp hours capacity (50% of 200 Ah)? I can't get into a position mentally to figure that example. Hah! wtf.

    Thanks for your reply. Can't find that exact specification, but there are other specs listed.

    Keep It Simple Solar

    Lead/acid battery charging tech has not changed. AGM likes a little different voltage setpoints. If you're living daily with solar, turn the voltage down, etc... He has written many updates, and for what we do here which is portable 12V energy, his stuff remains spot on. Go lithium if you...

    Thoughts on this trailer power system.

    Sincere question, no disrespect intended: What if the user of a 200 Ah battery bank used a 1500W inverter simply for the deliberately-planned luxury of a quick, convenient cup of coffee? I plan to install a system like this is in a very small camp trailer. In my case, this setup uses the small...
