A battery storage system 10 for use with an on-grid micro-generation plant (e.g. photovoltaic panels) to reduce power import and export from the distribution network or grid, and connected to the input of a solar panel emulator that presents one or more selectable voltage-current curves on its output to a Maximum Power point tracking (MPPT) circuit within a PV inverter. The battery storage and emulator arrangement allows for variable battery discharge rate selection and connection to a standard MPPT solar inverter 18a, 18b. The battery storage system further comprises a controller 14 to activate charging when the energy export is above a set threshold, and to adjust the maximum power point presented for discharge rate control when energy import is above a set threshold. A battery control module 26a, 26bmay be provided for each battery or battery bank, the control module having at least one of an over-charge, over-discharge, over-current or temperature protection function or a balancing function. |
