Can I use this for a 24v 1200watt dump load?

Yes you can use 24v but it will only use 460 watts. Power equal volts^2 / resistance. These are 2.5 ohm elements, 1.25 ohm when in parallel.

Too many products these days have no instructions or product info... Does this product come with either?? Thanks

As far as instructions I'm not sure what you are looking for. It's a 36vdc heating element, you connect the 2 power wires and it does the rest. The box has the wattage, voltage, and dimensions on it. If you are looking for amperage its 1200W / 36vdc = 33.3 amps. This isn't perfect but it is very close. For the pipe connection you apply a form of thread sealant and screw it in, then check for leaks. Hope this helps

When you connect direct to solar panels. Is higher volage from panels a problem. The panels I am looking are 40 volt.

You should be fine using 40v panels. Wire in parallel and watch your amps more than the volts. 36v 1200w element has a 33amp limit, so add up the amps produced on your panels and don't exceed that......and don't forget to protect the whole thing with a 40amp fuse or breaker in there.
