Small high-voltage panels for portable 48vdc based rig?

[copec]

I have a bunch of individual batteries I've made that I can attach or detach from my main house battery and are 48v (~51.8v nominal 14s). I've been using an individual "pure sine wave inverter" and boost mppt charger when I use it on the road, but am going to replace those with an AIO inverter. I wonder if anyone makes larger panels with a bunch of cut up cells in series to get up into the 150vdc range or so? It looks like I might just have to series a bunch of small 12v rated panels, but I figured I would ask if anybody knows of something first?

As long as the voltage of your PV's configuration is 5 volts over the voltage of the battery, the voltage of individual panels doesn't matter. A 12 volt panel typically doesn't produce only 12 volts, it's higher than that.

While I haven't gone out looking for it, I've never seen a commonly available panel that comes close to 100 volts.

Yeah, Their peak output is usually at ~18V or so, the reason I cited 12 volt panel is that they are the most common battery voltage charging target for small panels. I think I'm to get 10x50W panels and mount them together in series on something small I could wheel around. Then I could use a converted extension chord for which I could place them a ways off if I needed to, and the higher string voltage is most efficient for HF AIO inverters to convert to AC, in attempting to maximize direct energy usage when the sun is out.

 

[Any name you wish]

Here are some near 100V/150W ones from Santan: https://store.santansolar.com/product/used-solar-frontier-150w-thin-film-solar-panel/

They appear to be about 3ft by 4ft.

I thought I saw them have some higher voltage panels as well at there AZ location, I just don't see them on the site. You could call them and see what they have.

Nice, thanks!

There are currently a couple 400+ Watt panels with Voc above 80V for sale on Craigslist in northern Ohio.

But, they are 72 cell sized.
