Starting in April, Centrosolar, a German based manufacturer of Solar PV systems manufacturer said that it will start to offer solar energy storage systems that provides round-the-clock access to electricity produced by Solar PV Plants.
The new Cenpac Storage system comprises a storage battery, a battery inverter and an intelligent energy manager. Centro Solar worked with SMA Solar and Hoppecke for developing the product.
The batteries used in the system are lead-gel technology based and are available in three sizes: 3.7 kWh, 6.0 kWh and 7.4 kWh. The battery sizes have been specifically designed for single-family households where PV plants with operating capacities of up to 6 kWp, 9 kWp and 10.5 kWp are installed.
The batteries have a service life of approximately 2,500 cycles at a depth of discharge of 50% and are therefore particularly well suited for solar applications with high charge and discharge loads. Using a 7.4 kWh Cenpac Storage system, a four-person family with annual electricity consumption of 4,000 kWh is able to meet up to 85 per cent of their daily electricity needs with solar power. “The storage system allows plant operators to draw power whenever they need it – whether the sun is shining or not. Not only does storage improve the energy-related benefits of a solar plant, it also guarantees that the operator’s personal power needs are met,” explains Dr Axel Müller-Groeling, member of the Centrosolar Management Board.
The storage battery is complemented by the Sunny Island battery inverter, which has been specifically developed for own consumption by SMA. This is installed in the same way as a PV inverter and is more than flexible enough to work with different battery sizes. The Sunny Home Manager looks after the overall operation of the system. This energy management system regulates the flow of energy between the solar plant, the storage system, the household and the power grid. It monitors each and every component to ensure energy is managed intelligently.
Cenpac Storage will be available from April onwards.
