Want to seriously upgrade your solar?

[NOT MINE!] This would be an interesting addition to any Sportsmobile for true off-grid camping!

12 KW mobile solar generator trailer with 2-48volt 510ah low maintenance batteries, 10- 250 watt solar panels, 2-SMA Sunny Island 6048-US-10 Inverters, 1- Midnight Classic controller, 2- 50amp 240volt twist-lock recepticals and 4-20amp 120volt outlets. This trailer can power a house with 48.9 kwh (40kwh usable) of battery power or can be towed out to power a remote location such as a work site or concert/event set up. Built in 2012 but never used, it is set up on a twin axel 10k pound capacity trailer. Everything’s professionally wired up and ready to go! $13k

sweet. i could see some off grid property making great use of that. Might be a bit low and long for any kind of rough terrain, however.

Kind of a cool concept if you planned on staying in one location for an extended period, or owned Property in a remote location.
8yr old batteries... even if they were well maintained, they're still closing in on end-of-life.

I agree it's a cool concept, but also a little too much $ for the tech onboard. You could make the same power with a rooftop array on an Eb Transit or Sprinter 170, if you put one array on a sliding rack. New panels can do 400 watts.

Battery tech has gotten better too. Although 48 volt batteries could be forklift batteries.... IMO swappable forklift battery assemblies are a good option for off-grid.

But I don't get why they installed two inline parallel arrays, instead of putting one of the arrays on a sliding rack. This trailer is giant, especially in the context of portable power. My guess is the extra drag towing this around would end up burning more fuel than it saves vs running a generator. Good for cutting sound pollution I guess.

Looks like a DC Solar Solutions trailer. I've seen them up front and personal at several events. The Mrs and I were looking at off-grid properties last year, leasing something like this could bridge the gap until you set up a larger, full time system. of course, so could a generator, for 1/3rd the cost. The juice isn't worth squeeze for most of us in terms of $$$/KWh
