The OBI + OSE Off-Grid PV Workshop is a workshop where you will learn to design and install a complete, rooftop, 3kW, off-grid PV system for a home - for $3000 in materials. The workshop involves a complete install of a 3kW system from the roof mounting system - to a control panel with power measurement, a battery bank, wall outlets, and a super-efficient refrigerator. We will show you how to convert a chest freezer to a super-efficient refrigerator which draws only 8 watts of power on average. This 12x less than an average refrigerator - and is one of the critical elements that allow for building a low cost system with a small battery bank - as the main load at night is a refrigerator. We will measure all the loads in the system - so that a power management strategy emerges for running all loads in summer and winter. The intended audience is anyone who wants to learn about PV systems first hand - and especially anyone who wants to pay their last utility bill at a cost of $3k for a complete off-grid system like the one in the workshop. | |||

Overview
The OBI + OSE Off-Grid PV Workshop is a workshop where you will learn to design and install a complete, rooftop, 3kW, off-grid PV system for a home - for $3000 in materials. The workshop involves a complete install of a 3kW system from the roof mounting system - to a control panel with power measurement, a battery bank, wall outlets, and a super-efficient refrigerator. We will show you how to convert a chest freezer to a super-efficient refrigerator which draws only 8 watts of power on average. This 12x less than an average refrigerator - and is one of the critical elements that allow for building a low cost system with a small battery bank - as the main load at night is a refrigerator. We will measure all the loads in the system - so that a power management strategy emerges for running all loads in summer and winter. The intended audience is anyone who wants to learn about PV systems first hand - and especially anyone who wants to pay their last utility bill at a cost of $3k for a complete off-grid system like the one in the workshop.
