The answer to your question is no,your are not overestimating, and the experience you will get out of this is that this equipment is expensive no matter which way you go. If you have electrical power in your house dig a small ditch and bring the power to your shed. It will cost you more money and aggravation to use the alternative energy (solar panels, charge controller, inverter, battery bank,) not to mention the equipment and time to maintain the batteries than use the grid electricity to power your shed for 100 years. The only time you want to use alternative energy is when you are so far away from grid power that you have no choice.
