Alternator with 100% copper winding

K&S Basic inverter generators are equipped with a high-quality brushless alternator with 100% copper winding. The reliable and compact alternator, installed on permanent magnets in a plastic housing, can withstand maximum loads without damage and ensures long-lasting and stable operation of the generator.

universal control panel

The panel provides monitoring of all key operating parameters, an ECONOMY MODE switch that reduces fuel consumption by up to 50%, a Reset button for system reboot and voltage restoration.

Low noise level

The soundproof housing ensures a minimal noise level (62 dB Lpa 7m), comfortable operation, and easy transportation.

Accessory kit

Included: 16 А Schuko plug, candle key, PH2 screwdriver 6.0 mm, battery charging clamps.

Parallel connection

You can double the output power by connecting two inverter generators together using special KSВ PC-1 parallel connection cables from K&S Basic (not included in the kit). When connected in parallel, power loss is 0.2 kW of the total rated output.

ATTENTION! The product is sold without engine oil or gasoline. Before the first start, engine oil for four-stroke gasoline engines must be added. We recommend 10W-30 or 10W-40 oil. Always check the oil level before each use. Use only unleaded gasoline with an octane rating of 90–95 containing no more than 10% ethanol.
