The Zipper ZI-STE11000 generator from the manufacturer Zipper (ID 45040) is a reliable and versatile solution in the Power Independence > Generators category for domestic and professional use. This gasoline generator is designed to provide backup and autonomous power, combining the ability to operate with two types of output voltage: single-phase 220 V and three-phase 380 V, making it a flexible tool for various tasks.

Brief Overview

The Zipper ZI-STE11000 has a rated power of 11 kW at 380 V and 3.67 kW at 220 V. The heart of the device is a 4-stroke Loncin gasoline engine with a power of 13.4 kW, which, combined with a 30-liter fuel tank, provides up to 12 hours of continuous operation. Thanks to the overhead valve arrangement, the engine features reduced fuel consumption, which increases operational autonomy.

Technical Features and Advantages

A synchronous alternator with copper winding guarantees stable power quality, and the AVR module minimizes voltage fluctuations, which is especially important when powering sensitive equipment. The presence of fuel and oil level sensors and an hour meter facilitates service maintenance and monitoring of the device's condition. A rigid steel frame provides mechanical protection and durability, and transport wheels make moving around the site more convenient.

Operating Tips

Before switching between 220/380 V modes, always disconnect all loads and follow the instructions for the mode switch, as switching under load is prohibited. When connecting single-phase appliances, use phase and neutral; three-phase appliances are connected to three phases. Note that the power of a three-phase generator is distributed among the phases.

Frequently Asked Questions

How are 220/380 V modes switched?

Switching is done by a mechanical or electronic switch. Disconnect the load before the switching procedure.

What types of alternators are used?

Similar generators may use synchronous multiphase alternators with multiphase winding, alternators with two independent windings, or with the ability to switch winding configurations.

Why might the voltage drop on other phases when one phase is loaded?

The reason is phase imbalance. Uneven load distribution causes voltage and frequency fluctuations, so it is recommended to distribute consumers evenly across the phases.

The Zipper ZI-STE11000 model is suitable for backup power for homes, construction sites, small businesses, and for use in field operations. The combination of high power, a large fuel tank, a well-designed control system, and robust construction makes this generator a practical choice for those who need stable autonomous power.
