    Anyone purchase from Gobel Power, experience?

    why is it sketchy sending through paypal? Don't they offer buyer protection? I noticed Gobel has direct bank transfer to avoid the 4.4% fee, that sounds scary.

    Building entirely new roof, how to find best angle(s) for solar?

    we don't have that much space on the lot; entire lot is like 250 sq. meters, much of that is occupied by the house. Probably will build a carport using bifacials though.

    Building entirely new roof, how to find best angle(s) for solar?

    The roof of the house we bought is totally shot, it all must be totally rebuilt (rafters and all). So I'm thinking to just make a flat roof tilted at a certain angle or angles to optimize our solar production. We'll make it generally South facing and the builder said he can do about a 20 deg...

    Ah I only needed one (3.3kw array). I went a bit crazy with the PowMR because we were able to get them so cheaply. I was thinking to redo my setup so 4 panels per charge controller. I was able to get a "used" epever which was just a return for $160 including the MTS50. I did not buy three of...

    Why do powmr sell their units so cheap now?

    So in the past I've had a couple of their older mppt models (metal housing) they worked ok when they worked. Very touchy if you accidentally loose battery power while connection with panels plugged in they would die. I recently bought 3 x new powmr pro 60 amp 12/24/36/48 mppt chargers...

    Diy DC USB pd for laptop and highspeed charging for tablet

    I have a few related issues ... 1-I would like to make a DC USB PD charger for a laptop which needs 100w. House voltage is 48v. Most of our things run on DC, fans, lights, USB charging etc. Is there any special circuitry required or is this as simple as sending 5v over a 20v USB line? I...

    Did I just got scammed by a forum member??

    There are convenience shipping places like Mail boxes eetc everywhere in california, the state is literally the 6th largest economy in the world lots of shipping conveniences. If this guy is real i sure hope he will at least upgrade your shipping at this point; it's the human thing to do

    yes Frank, something smells funny to this situation. so it starts as "pal has back surgery" then the guy falls off the face of the planet and is irritated you are concerned to get your stuff? He knows your family is totally off grid so without the stuff you are down in battery power ... so...
