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

The StromerPower 165kVA Three Phase Alternator (STRO-165K) is designed for mid scale generator builds, commercial and industrial applications and pump systems. Assembled under a strict ISO 9001 quality assurance scheme, this 4 pole brushless unit gives engine builders a dependable baseline to manage large starting loads without forcing sags across distribution lines.

  • Dependable output: Supplies a reliable 150kVA prime rating for continuous application and up to 165kVA standby power at a stable 50Hz frequency.
  • Responsive AVR control: An integrated automatic voltage regulator that counters line changes to protect equipment.
  • Low reactance windings: High purity copper windings to minimise impedance losses and maintain clean power while improving fuel efficiency.
  • Rugged core housing: A thick steel mounting base, Class H insulation and an IP23 weather protective shell withstand humid and dusty environments.

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