Mackies Electrical recently had the opportunity to upgrade an off-grid solar battery system for an award-winning residential property in Hannam Vale, NSW, on the Mid-North Coast. The property was purchased in 2020, and the existing ten-year-old off-grid solar battery system required an upgrade to suit the power requirements of the new owner.
The original system comprised a 24 Volt Selectronic SA32 inverter, and 1000Ah flooded lead-acid batteries. However, the system needed to be upgraded with a swimming pool, air conditioning, and a shed. Mackies Electrical was approached to design and install a new system to meet the new owner’s energy requirements.
The new system is specifically designed to cater to the planned expansion, with a total system size of 8.9kW PV and 40kWh battery storage. The battery storage consists of ten PowerPlus ECO4840P modules, while almost 9kW of solar panels are used to charge the batteries. The system also includes a 7.5kW Selectronic SP Pro battery inverter and a Fronius 8.2kW solar inverter.
