Diesel Generators — all types, all capacities. Our AC gensets are designed to meet the demands of telecom operators: low-noise levels, easy maintenance, low fuel consumption, durability/reliability, remote monitoring & control, and enhanced alarm reporting. We offer water cooled, oil cooled & integrated air cooled engines — Kohler, Perkins, Deutz, Kubota and more, coupled to alternators such as Leroy Somer, Stamford, Marelli, Mecc Alte, Linz and others.
Batteries — all technologies, from 1.2 Ah to 2000 Ah. We provide a wide variety of indoor and outdoor batteries mostly used for backup power for telecommunications equipment, supplying 2V, 12V, 24V and 48V battery systems across multiple technologies: VRLA (Valve Regulated Lead Acid), AGM (Absorbent Glass Mat), GEL, and Lithium-ion (LiB).
Renewable Energy & Hybrid Solutions — ideal solutions to optimize the overall TCO. To optimize CAPEX and OPEX, we offer customized hybrid solutions that maintain an excellent balance between system design and cost. We offer a wide range of both sizes and technologies, designed to power various loads with various geographic requirements. Solar systems include solar PV, rectifier modules, MPPT modules, batteries, cabinets, RMS, steel structures, civil works and engineering services.
DC Cabinets — GTC can provide a wide range of outdoor cabinets, enclosures, racks and sub-racks, in addition to offering integration services for the telecommunication and electronics industry.
GTC also supplies Telecom-in-Box (TiB) solutions, Solar on Wheel systems, and electrical accessories including ATS (Automatic Transfer Switches), AVR (Automatic Voltage Regulators), Smart Electrical Meters and Transformers. Contact us for the full product catalogue and datasheets.
