I found a deal on 4000 watts of solar panels for $400 but they are high voltage like 200 volts per panel. Am I correct to assume these are not suitable for DIY off grid projects?

Why would you assume this?

Dam up a nearby valley and use the output of the panels to pump water into your new reservoir. Pumps are simple things and will happily use 200 volts. You can then use off the shelf hydro equipment to get electricity out of the reservoir's gravity potential.

High low amp can use smaller wire tho from the panels to the controller
Probably a good deal for the right set-up

You can easily just parallel them into a 3-5sXp at 800-1000V strings with a 1500V rated inverter, it's not rocket science. This really isn't much different than regular solar panels, maybe cabling will be slightly more messy. If there's nothing wrong with the panels then it's perfectly fine to buy these. Older inverters have issues with the high voltage, but all modern inverters are at the very least 400V-ish.

Then convert volts into amps :>

What do those boxes do anyways?
A step down transformer isnt hard to make and if its dc it can be converted to ac. Lastly if you need to store the energy theres car batteries. What am i missing?

Wide input range DC-DC converter might work.

Lotta 250-450 volt mppt chargers out there anon. Look at their amp limits and the panels wiring gauge.

I have an idea and yeah it's probably stupid, since I don't know WTF I'm talking about, but if you are in a mostly cold climate, for that kind of deal I'd grab these and use them STRICTLY for heating. Wire them straight into some giant, cheap electrical baseboard heaters and just let'em run continuously. They'd handle the voltage with no problem and it's a purely resistive load.

Just ordered some pecron shit, getting into solar for the first time. Whats the current meta on 400w ish portable panels? I ordered a few to test out and fuck around with but will probably get to like 3kw worth eventually, wait for black friday and order 4-5 good N type is kind of my current plan

I dont know shit about solar but how is it someone has 4 kilowatts worth of solar cells with no way to use them? Don't they make controllers or BMS type systems to use them? How do the manufacturers suggest you use them?

That's probably the VOC, under load it drops to 50v.

>solar general isn't up
You guys in this thread are probably knowledgeable on this. I have some relatives who want to install solar, this is in Europe. I'm more of a /g/fag than a /diy/fag so I don't think making our own system is feasible, and I also don't want to be on the hook for helping them support a diy-ed setup; are there any /diy/ approved brands for solar batteries/controllers/systems?
They're unironically considering a tesla powerwall, and I'm thinking surely there must be things that are cheaper and better and less pozzed, without going the route of buying our own inverters and batteries and all that shit and wiring them up all on our own.
