Telecommunication - Using of Off-Grid inverters SUNNY ISLAND in Base Transceiver Stations

Contents As part of the global development of telecommunications networks, Base Transceiver Stations (BTS) are also frequently constructed in Off-Grid locations or Bad-Grid locations. The Sunny Island is very well suited to ensure the electricity supply to a BTS even in such locations due to its flexibility and robustness. Off-Grid systems with Sunny Island are distinguished by the following features: • Possibility for the supply of AC loads and DC loads in battery operation. • Optional use of 1-phase or 3-phase generators and the power distribution grid. • Selection between positive or negative grounding of the DC bus. • Flexible system design with the use of various renewable energy sources. This document explains in detail when the use of a Sunny Island for the supply of electricity to a BTS is expedient and what is to be taken into consideration for this.
