Uninterrupted transmitter power without the grid, even in the middle of the ocean:Broadcasting PV station in the Indian Ocean
Customer challenge
VONSCH solution - turnkey
The broadcasting station consists of an air-conditioned container with a +RH switchboard and electrical equipment for an autonomous PV system with battery charging that powers the switchboard with the customer equipment BASE STATION / REPEATER & SATELLITE RECEIVER. The batteries are charged during the day by 2× MPPT solar chargers FOTO CHARGER DC 48. The 28 VDC needed to power the customer equipment is produced by two 500 W controlled power supplies. The control system provides complete battery management. The whole system meets safety functions – central stop circuit, battery protection (at low capacity and at a high level of flammable gas), overvoltage protection on the photovoltaic DC input, fire protection, and temperature measurement in the individual parts of the container and on the battery strings. Visualization of the whole system is available on a touch display. Via the eWON module and a built-in PC, the parameters can be visualized and set remotely.

Project in numbers
What the customer gained
- Uninterrupted power for the transmitter (BASE STATION / REPEATER) with no grid connection
- Solar charging during the day → lower generator fuel consumption
- Complete battery management and protection → longer life and safety
- Remote supervision and setup via eWON → service without travelling to the island
