Failure to upgrade Alphaess storage.
I had a battery backup installed 2 or 3 years ago. My main motive was that I would have power if there was a power fail. It worked in the first power fail. but not again. the installer tells me it could never have worked as I need more storage, When I installed I was assured if I need more storage, I could extend. Now that I want to extend I am told Alphaess is no longer in business and I have to install a brand new system.
