We offer a range of  prime and standby power solutions that include new "custom-built" diesel generators, pre-owned generators as well as "UPS's" and "hybrid-Solar" inverters. 


Custom built diesel generators that range from 9KVA up to 2500KVA+ "Prime" and "Standby" rated power-plants that are fitted with OEM diesel engines and various options to meet almost any requirement. From base mounted (Open-Frame) or Sound attenuated (Silent/weatherproof) and containerized generators with the option of the "Base load panel" for manual operation or the upgraded "Anti-Mains Failure panel" and AMF controller that will provide full automatic control and power transfer for an effortless changeover solution in the event of any fluctuations, spikes in supply or complete power loss.


Our range of powerful and true rated, custom built generators are fitted with OEM diesel series engines/(electra-packs), that include brands, such as Cummins, FAW, Lovol, Perkins, Scania, Volvo-Penta and more. The preferred choice of OEM diesel engine will be closely coupled to one of the leading brands in high-quality brush-less alternators - choices include Stamford, Marelli, Mec-alte, Leroy Somer as well as Evotech and Voltazz.


Custom built diesel generators are fitted with "Deep Sea Electronics controllers" others brands are also available on request

All our electronic controllers offer full protection, monitoring of set parameters as well as emergency cut-offs in the event of oil pressure loss, low fuel and over-heating scenarios, this prevents any fault from causing major damage to the internal parts of the diesel engine.

Generator control panels offer manual starting and power transfer operation as well as the "Anti-Mains Failure" panel for automatic starting, power transfer and mains power monitoring with automatic switching capabilities.
