This is a brand new unused battery that was installed, and then Ambia Solars installers said it was not functioning as expected and then uninstalled it to return to manufacturer- it has sat on my driveway since April because no on from Solar Edge ever showed up to pick it up. I’m sure that for someone familiar with the equipment is has some value rather than just going to the electronic dump yard. If anyone would like to come pick it up it’s yours.
