Abstract: A customer's solar array is connected to a utility-owned battery and inverter system. The battery and inverter system may convert DC power from the solar array or a battery bank to provide AC power to the grid. The inverter system may also convert AC power from the grid to DC power to charge the battery bank, or the battery bank may be charged by DC power from the solar array. The utility's inverter system is connected to the customer's premise on the utility's side of the meter. A transfer switch provides either grid power to the premise or AC power from the inverter via the battery bank. A solar production meter on the utility side measures power flowing from the solar array to the grid, as well as power flowing between the battery bank and the grid.
