- Diesel powered β efficient, high-torque output with long engine life.
- Recoil / key / electric start β dependable starts in tough conditions.
- ATS connection ready β auto-start on mains failure (ATS box included).
- 35Β L fuel tank β extended runtime for longer shifts.
- Low-oil shut-off β built-in engine protection.
Run multiple heavy loads together β manage start surges and socket amperage limits.
π Sockets & Inputs β Front Panel at a Glance
High-draw appliances / distribution boards.
Low-voltage tool circuits (site use).
Interface for auto-start & monitoring.
β‘ Running vs. Starting Watts β Know the Difference
Typical values β always check device labels. Respect socket limits (e.g., 32A at 230/240V β 7.4Β kW per outlet) and balance loads across outputs.

Guide only β add up running watts for items used together, then ensure the single highest starting surge and per-socket amps stay within limits.
π§© Can I Run More at Once with 12 kW Running?
Yes. Higher capacity means more simultaneous loads. With 12Β 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 (180β200A) + lights + chargers; start compressor separately.
Use a proper transfer switch/ATS for premises. Consult a qualified electrician for connection and load balancing.
