PROJECT DETAIL
Objective:
Wanted power on site before family home and shed build commences. Had strong sustainability motivations. The system was required to power a shed initially and a house later on.
Load Analysis:
22-24kWh average daily winter/summer demand; 10.2kW design surge
Site Considerations:
No infrastructure available. Solar ground frames + self contained EnergyBox required
System Design:
- OEA Complete 130-48 System – 13kW 1-phase output
- OEA EnergyBox System – install under solar ground frames
- 79kWh sealed gel battery storage
- 5kW Polycrystalline solar array on ground frames – yielding an estimated 168% of average demand, and 123% in winter
