PROJECT DETAIL

Objectives & Site Considerations:

Keith wanted a small off grid system for a shed, to run 4 hi bay LED lights, hand power tools, and a few trickle battery chargers. The shed was completely wired and was previously running solely off a diesel generator for one to two weeks a month. Keith was prepared to still use the generator when using his welder, car hoist, or air compressor to keep the system sizing and cost down.

The shed roof runs roughly north south and is 5m high but had a lean to on northern end facing north which is approximately 2.5 mts high.
