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

The StromerPower 22kVA Single Phase Alternator (STRO-22K) is a single phase alternator manufactured under a strict ISO 9001 quality system. Designed for diesel generators, mobile power units and pump setups, this 4 pole brushless unit handles heavy motor starting loads without letting the voltage drop.

  • Power Capacity: Supplies 22kVA power output at a steady 50Hz frequency.
  • Automatic Voltage Regulation: Employs an industry standard SX460 AVR to keep voltage stable within 1% and protect sensitive electronics from sudden spikes.
  • Clean Power Windings: Utilises a 2/3 pitch stator winding layout to suppress harmonic noise, keeping total harmonic distortion under 5%.
  • Standard Mechanical Interface: Built with a rugged single bearing design for precise alignment with standard SAE housings and an IP23 weather resistant frame.

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 22kVA Alternator

The StromerPower STRO-22K is a 22kVA single phase alternator manufactured under a strict ISO 9001 quality assurance system. Operating at a standard 1500rpm, this 4-pole brushless unit is built for installations like pump systems and systems that run on single phase power. It provides a stable baseline of electricity to keep your operations powered when the grid fails.

StromerPower 22kVA (STRO-22K) Alternator Key Features

  • 22kVA Single Phase Output: Supplies up to 22kVA standby power rating at a stable 50Hz frequency.
  • ISO 9001 Certified Build: Manufactured under strict quality control standards to guarantee consistent performance.
  • Factory Fitted AVR: Equipped with an Automatic Voltage Regulator module to lock line output within a tight margin and shield sensitive electronic gear from voltage spikes.
  • High Purity Copper Windings: Enhances mechanical to electrical conversion efficiency to improve performance.
  • Smooth Balance Profile: Engineered with tight internal tolerances to minimise vibration, wear and noise.
  • Industrial Frame Protection: Utilises an IP23 weather-resistant housing and Class H thermal insulation layers to ensure steady output in hot, dusty or humid workspaces.
  • Expanded Top Terminal Box: Features a spacious junction box that gives technicians immediate access for quick wiring links and easy AVR adjustments.
  • Low Reactance Design: Controls transient thermal spikes and suppresses wave distortion across complex commercial or rural power distribution networks.
