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

The StromerPower 44kVA Three Phase Alternator (STRO-44K) is engineered for generator builds, mid sized commercial and industrial applications and pump systems. Put together under a strict ISO 9001 quality system, this 4 pole brushless unit handles starting loads without forcing voltage drops across your site.

  • Balanced output: It supplies a steady 40kVA prime power rating and scales up to 44kVA standby capacity for emergency outages at 50Hz.
  • Automatic voltage control: The built in AVR automatically balances line changes on the fly to shield components and equipment.
  • Low reactance windings: Uses high grade copper to lower internal impedance, keeping wave distortion to a minimum and improving fuel efficiency.
  • Chassis and insulation: Built with a steel frame, Class H thermal insulation and an IP23 weather enclosure to protect the internal components in dusty or humid workspaces.

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 44kVA Alternator

If you need reliable power for a commercial system or a diesel generator, the StromerPower STRO-44K is built for exactly that. It is a 44kVA three phase alternator designed to handle standby duties. Operating at a standard 1500rpm, this 4 pole brushless unit gives you a dependable baseline to keep production lines, cold storage systems and Air Conditioning running smoothly when the grid goes down.

StromerPower 44kVA (STRO-44K) Alternator Features

  • Power delivery: It supplies a continuous 40kVA prime power rating and pushes up to 44kVA standby output for emergency backup at a stable 50Hz frequency.
  • Automatic voltage control: The built in AVR automatically balances line changes on the fly, keeping output stable to protect equipment.
  • Copper windings: Uses high grade copper layouts to lower internal impedance losses.
  • Vibration management: The internal components are dynamically balanced to limit operational resonance, keeping the unit running quietly and reducing mechanical shaft stress.
  • Chassis and insulation: Features an IP23 outer shell and Class H thermal protection for tough environments.
  • Junction box access: The terminal hub gives technicians room for quick cable links, phase balancing and regular maintenance.
  • Sine wave quality: The low reactance design limits wave distortion to ensure a smooth, clean electrical supply.
