We offer industry leading 24 month / 1,000 hour warranties on our engines and diesel generators.

The StromerPower 1100kVA Three Phase Alternator (STRO-1100K) is a heavy industrial three phase alternator manufactured under ISO 9001 quality assurance. Designed to provide high capacity power for large diesel generator sets, localised micro grids and major plant infrastructure, this 4 pole brushless unit is engineered to manage large electrical starting loads without dropping line voltage.

  • High Capacity Output: Delivers a continuous 1000kVA prime power rating and up to 1100kVA standby output at a stable 50Hz frequency (0.8 power factor).
  • MX341B AVR Control: Features a premium automatic voltage regulator that keeps output stable within 1% to protect equipment from spikes and sags.
  • Single Bearing Engine Alignment: Built with a rugged single bearing design optimised for alignment with standard SAE housing flanges and clutch flex plates, all within a protective IP23 steel enclosure with Class H insulation.

We offer delivery across Sub-Saharan Africa at the best prices.

SUPERIOR QUALITY AND PERFORMANCE

StromerPower sets new global standards in all aspects, from design, manufacturing, material selection, production and testing equipment, tooling, and quality control.

GENERAL SPECIFICATIONS

StomerPower 1100kVA Alternator

The StromerPower STRO-1100K is a high capacity 1100kVA three phase alternator manufactured under a strict ISO 9001 quality assurance system. Operating at a standard 1500rpm, this 4 pole brushless unit is engineered specifically for heavy industrial operations like large fabrication plants, retail centres and other heavy power application. It powers large generator sets, keeping critical infrastructure and high output distribution lines operational during extended grid failures.

StromerPower 1100kVA (STRO-1100K) Alternator Key Features

  • 1100kVA Three Phase Output: Supplies up to 1100kVA standby power and a continuous 1000kVA prime rating at a stable 50Hz frequency.
  • ISO 9001 Certified Quality: Built under strict manufacturing standards to ensure consistent performance.
  • Integrated AVR Module: Factory fitted with an Automatic Voltage Regulator to lock line voltage within precise limits and shield automated machinery from destructive voltage spikes.
  • High Grade Copper Stator: Engineered with premium copper windings that lower internal impedance to maximise efficiency and help reduce engine fuel consumption under full factory loads.
  • Balanced Internal Tolerances: Machined with precise rotational balance to minimise mechanical wear and lower structural vibration.
  • Industrial Grade Protection: Features Class H thermal insulation and an IP23 weather resistant housing to protect internal components in hot, dusty or humid environments.
  • Accessible Terminal Enclosure: Features an oversized, top mounted junction box that gives technicians clear access for large cable connections, diagnostic testing and AVR adjustments.
  • Low Reactance Electrical Design: Controls transient voltage fluctuations and suppresses wave distortion to maintain a clean sine wave.
