The device can supply the electricity to the grid even during a minimum flow of water, with high quality of current: (cos φ = -1, the current THD 5%). The device is equipped with an emergency electro-hydraulic. The generator is connected to the screw turbine via a gear. The level of the water is detected by an ultrasonic level sensor and locks level are automatically controlled by DC drives. DC dr…
In a separate, ventilated kiosk there is an enclosure for FVE1 and the battery.
FOTO CONTROL 1f 230/375 DC inverter is used as an electronic MPPT controller of AC coil power. This solution increases the energy yield by 30-40% comparing to the standard switch.
The need to reduce the cost of the house and feed the electricity surplus into the grid, the need for remote monitoring of the inverter + status messages over e-mail was addressed as follows: Inverter FOTO CONTROL 230 / 375 DC operates in on-grid mode. RM WEB module is used for the monitoring of the power plant.
The single-phase photovoltaic hybrid system with the household consumption covering feature was installed. In case of power failure and sufficient battery capacity, the plant is able to backup the appliances in the one phase – inverter instantaneously and smoothly enters off-grid mode.
Hybrid PV system is able to operate in three different modes:
