I guess that i can qualify as an "off grid battery wrench" I also do large motive power batteries.The difference being mostly that they are on wheels. I have recieved 1 on grid call in 2 years and they were looking to connect an off grid system to the grid. So much for qualifying for NABCEP ! The immediate area that I am in gets lake effect off Lake Ontario and averages 1 hour a day of sun in the winter That's an estimate, were worse than Syracuse, NY. They even took Syracuse off the isolation charts for a few years, too depressing I guess.
