This off-grid system was originally designed to work as a grid-connected energy storage system but the power supply was interrupted due to a mobile (NBN) tower installation on the same property. It was decided to run the system completely independent of the grid and it has been operating far better than expected and saving the owner close to $2500 in electricity costs per month.
