I know this adds considerably to the cost & won't work in every situation, but if you use the solar panel to charge a camping battery (one, or more + rotate) it can then be used to run small appliances & electronic devices w/o worrying about whether the circuit or grid is compatible.
uncleporkdaddyVery curious about these. Permitting my panels was the most time consuming part by far. However, it is unclear if these are safe and legal where I live
