Maxmech RFS-15000ET Electric Start Generator “11.9 KVA 9.5 KW (380V)”

The Maxmech RFS-15000ET Electric Start Generator “11.9 KVA / 9.5 KW (380V)” is a robust and high-capacity generator that stands out due to its 380V (Three-Phase) output capability, in addition to the standard single-phase 230V. This makes it suitable for a broader range of heavy-duty applications.

Let’s break down its key aspects:

Key Specifications and Their Meaning:

• Maxmech RFS-15000ET: The model designation. “ET” implies Electric Start, and possibly “Three-phase” or “Tropicalized” depending on Maxmech’s specific naming convention.
• Electric Start Generator: Equipped with a battery and a starter motor for convenient key or button ignition. This is vital for a generator of this size, as manual starting would be physically demanding. It almost certainly includes a manual recoil start as a backup.
• 11.9 KVA / 9.5 KW: These are the power output ratings:
  • 11.9 KVA (KiloVolt-Amperes): The apparent power or maximum output. This is the total power the alternator can produce, and it’s particularly important for handling the starting (surge) current of motor-driven equipment.
  • 9.5 KW (Kilowatts): The rated power or continuous running power. This is the actual usable power the generator can reliably supply over extended periods.
  • Power Factor: Approximately 0.8 (9.5 KW / 11.9 KVA), which is standard for portable generators.
  • In Practice: You should size your continuous loads to the 9.5 KW rating. The 11.9 KVA is its capacity for momentary power spikes, allowing it to start larger machinery.
• 380V (Three-Phase): This is the most significant differentiator.
  • What is 380V Three-Phase? Unlike single-phase power (which uses two wires, typically 230V in Kenya, and has fluctuating power delivery), three-phase power uses three live wires (and often a neutral wire) with electrical phases shifted by 120 degrees relative to each other. This provides a constant, smooth, and more efficient power delivery.
