The aim of VONSCH developers was to produce highly reliable, true sine wave inverter with high efficiency and long durability.
FOTO CONTROL 1f 230/375 DC is an inverter for small systems designed to cover own household consumption.
FOTO CONTROL 1f 230/375 DC is a device for transformation of DC voltage generated on the terminals of the solar panel after impact of photons to single-phase sine wave voltage in single-phase AC power grid.
Inverter is designed to produce single-phase voltage with an amplitude of 230 V AC and frequency of 50 Hz in on-grid operation.
FOTO CONTROL 1f 230/375 DC is able to work in a wide range of input voltage - voltage of photovoltaic cells within the range from 200 V DC to 700 V DC.
The advantages of FOTO CONTROL 1f 230/375 DC are low noise, high efficiency, the possibility of extending to three-phase system (operation of multiple inverters) and the possibility of integrating new perspective features. Software required for seamless connectivity to computer is freely available for download in the "support" section at www.vonsch.sk.

Continuos pure-sine power regulator SRVS 10/230AC
For using the excess energy from ypur PV system, we have developed a continuous power regulator SRVS 10/230, which can be used to distribute unused power - the excess of the panels,
and use it to supply the heating units like a boiler coil or an electric radiator. The main advantage of our power regulator is the sine shape of the output voltage, which reduces any undesired disturbance of the grid or surrounding devices. Continuous power regulator allows optimal use of your photovoltaic system.

Continuos power regulator SRV 10/230AC
Electronic continuous power regulator SRV 10/230AC is used to power an electrical resistive load, for example domestic hot water heater (boiler) or floor,
wall or ceiling heating resistance wire. SRV 10/230AC allows control of AC voltage while maintaining high efficiency and low interference to the network.
Supply voltage for the SRV 10 / 230AC is provided from the output of the inverter. This makes the exploitation of maximum power from PV panels possible at
concurrent requirement for zero grid injection.
