⚡ Running vs. Starting Watts — Know the Difference

Running watts = power to keep equipment operating.
Starting watts = brief surge to start motors/compressors.

Typical values — always check device labels. Respect socket limits (e.g., 32A at 230/240V ≈ 7.4 kW per outlet) and balance loads across outputs.

📐 What Size Generator Do I Need?

Item Typical Running Typical Starting GP12800D?
LED TV + Router + Lights 150–250W ≈ Same ✅ Many circuits
Fridge-Freezer 120–200W 800–1200W ✅ Multiple units
Work Lights (LED/Halogen) 300–1000W ≈ Same ✅ Banks of lights
Microwave 800–1200W ≈ Same ✅ With other loads
Circular Saw (7¼") 1200–1800W 1800–2400W ✅ Yes
Space Heater / Kettle 1500–2000W ≈ Same ✅ Several at once
Cement Mixer 800–1500W 2000–3000W ✅ Yes
Air Compressor (≈3 HP) 2200–2600W 5000–6500W ✅ Yes (solo start)
Welder (≈200–250A) 5.5–6.5kW 6.5–7.0kW ✅ Yes
Water Heater (electric) 3–4kW ≈ Same ✅ Solo circuit
Site Cabin (lights + heaters) 4–8kW Varies ✅ Yes (balance)
Small Tower A/C 1.5–1.8kW 2.4–3.0kW ✅ Multiple units

Guide only — add up running watts for items used together, then ensure the single highest starting surge and per-socket amps stay within limits.

🧩 Can I Run More at Once with 12 kW Running?

Yes. Higher capacity means more simultaneous loads. With 12 kW running you can power, for example:

  • Home backup: fridge + freezer + broadband + lighting + TV + microwave + kettle (stagger heat loads).
  • Site cabin: heaters + lights + sockets + kettle; split across the two 240V 32A outlets.
  • Workshop: welder (180–200A) + lights + chargers; start compressor separately.

Use a proper transfer switch/ATS for premises. Consult a qualified electrician for connection and load balancing.

🧭 Why Choose a Diesel Generator?

  • Fuel efficiency — lower consumption per kWh vs petrol.
  • Durability — engines built for heavy duty cycles.
  • Lower running cost — typically reduced cost per kWh.
  • High torque — excels with motor/compressor loads.

🧠 Tips for Choosing the Right Generator

  • Total your running watts for everything you’ll use together.
  • Identify the largest starting surge (motors/AC/compressors) and keep headroom.
  • Match outlets & amps — 32A sockets ≈ 7.4 kW each at 230/240V.
  • Plan installation — use ATS/transfer switch and a qualified electrician.
