    I would qualify that to say that there is no way to get ahead when grid is available. For off-grid and for isolated small loads like gates (or garage doors) the cost stays the same but the alternatives become less attractive in comparison.

      OK I will give you that one. Point is Battery systems should only be used when there is no other economical choice. Let's not try to fool anyone. Off-grid battery systems are expensive and NOT environmentally friendly as they can never offset emissions. It really Jacks me up when someone puts in a off-grid battery system because they think it is earth friendly. Nothing could be further from the truth.

        You deleted my post? I'm actualy not suprised. All I was saying was that a safe code compliant install is the most important thing when designing a system. My post that was deleted had a link to video that showcased this point. Forums are usually places of OPEN discussions.

          Green - I sent you, the other moderators and the forum boss a private message about this - but you seem intent on trying to make some silly point.

          Your post was trying to justify your point 1) that the plug and play (plug into a wall socket) types can be done legally if done in a different manner - hardwired and 2) Non UL compliant equipment can be accepted by the utility providing the equipment is tested at your cost (about same thing as UL approval) or if the POCO just accepts the equipment which is not at all likely as they would then assume the liability involved.

          Wise up and stop tilting windmills - forums are not for somewhat strange concepts to be promoted as you keep trying.

            Tilting against windmills can actually be very entertaining, especially where a bureaucracy is involved, but I can't recommend it to everyone.
            Tilting windmills is best done when trying to draw power from vertical winds up the sides of large buildings.

              Allow me to explain

              I'm not actualy tilting at windmills, but anyways... Like I said to Russ in private, I'm definetly not endorsing these cheap inverters, what I was trying to convey was safe, code compliant installs whatever equiptment is being used. That's all.
