Voltwerk electronics is a leading manufacturer of power components for photovoltaic systems. Due to their maximum efficiency factors the highly efficient inverters by Voltwerk are among the most powerful inverters in the world – in the field of small scale applications as well as in the field of solar parks in the multi megawatts category

VS Hybrid
Integrated energy management system
VS 5 hybrid is a combination of a transformerless 5 kW inverter, a lithium-ion battery with a capacity of 8,8 kWh as well as a management system with a colour touch display. The battery capacity can be expanded if needed - the casing is designed to fit 13,2 kWh. Storing solar power enables the owner of a PV system to cover his own-consumption with PV power in times of low irradiation, e.g. in the morning, in the evening and even at night as well.
The energy is either fed in directly from the PV system into the public grid, taken from the battery or provided simultaneously from both sources. Only if those sources do not provide energy, electricity is taken from the grid. In case of a grid failure the system will switch to stand-alone operation.
