The Sonnenschein@home Lithium 9.0 is a modular battery with a nominal voltage of 48 volts (actually 54V). The chest-like battery features excellent cycle life (5000 cycles at 80% Depth of Discharge) with zero maintenance.
Each module can store 8.5kWh of energy (usable energy 6.8kWh) and comes with its own battery management system (BMS). Up to 12 modules of the same type can be connected in parallel. In a parallel configuration one module assumes the role of Master BMS. The Master BMS communicates with the energy management system of approved inverters, e.g. from SMA (Sunny Island), Victron or Selectronic (SPMC480 - 482) using CAN bus communication protocol.
We install solar systems in Northern NSW and Southern QLD.
QLD: Gold Coast (from Coolangatta to Southport), Nerang and Hinterland (Beaudesert) and out West (Warwick, Stanthorpe, Killarney)
