The modular energy storage system
With our state-of-the-art energy storage solutions, Sunstream users will be more independent of electricity prices and will use their own photovoltaic electricity when they need it. With the new modular lithium-ion energy storage, the self-generated photovoltaic energy can be stored in battery modules for later use.Excess energy can be selectively fed into the grid or into the energy storage device by the inverter when the need is there - in the evening, at night and during periods of low sunshine.

cluster solutions
With a higher energy requirement up to 12 batteries can be connected in parallel to a cluster. To increase the performance, several inverters can be connected in parallel. Both single- or three-phase system configurations are possible.
