Objectives & Site Considerations:
This client had an existing grid-connected house on a farm property that he wanted to take ‘off-grid’ as much as possible. Energy independence was a big driver for him, as well as blackout protection because outages are common in the area. The client expressed a preference for lithium-ion batteries and premium-quality solar panels.
He was building a new shed 60m away from the house, which would house the battery system, and wanted the solar panels on ground-mounted frames to maximise solar output. The electricity distributor placed a limitation of 5kW/phase export to the grid, and because the system design was larger than this it needed to be export-limited.
Average summer demand: 22kWh/day
Average winter demand: 22kWh/day
Including the Grid Fail kit allows the client to switch from grid power to generator power as needed, allowing him to use a generator to charge the batteries if the grid goes down. By using self-managed batteries and smart system design, the client has been able to expand his system twice since the original installation.
