The SOLAX SDJ8500ME diesel generator from Solax is a reliable solution for autonomous and backup power supply for single-phase consumers in private households and small commercial facilities. This unit is designed to operate at 230 V and combines power, efficiency, and ease of maintenance. Category: Energy Independence > Generators.

The SOLAX SDJ8500ME has a rated power of 5.2 kW and a maximum power of 5.7 kW, allowing it to stably power a wide range of household and professional equipment. The durable four-stroke engine ensures long-term operation under increased loads, and the 12.5 L fuel tank allows for extended use without frequent refueling. The average duration of continuous operation under normal load is typically about 8–10 hours, depending on the usage mode.

A synchronous alternator with copper winding is used for high-quality power generation, and an automatic voltage regulator (AVR) ensures a stable and uniform power supply. This combination allows for safe connection of devices sensitive to voltage fluctuations, including electronics and medical equipment, provided the power is correctly selected.

Key Features

• Phase: single-phase (230 V)
• Rated power: 5.2 kW
• Maximum power: 5.7 kW
• Engine: durable four-stroke
• Fuel tank capacity: 12.5 L
• Starting: manual start and electric starter
• Alternator: synchronous with copper winding
• Regulation: automatic voltage regulator (AVR)
• Outlets: 2 x 230 V outlets
• Protection: low oil level protection
• Control: hour meter
• Design: open design with rigid frame
• Mobility: wheels and handles for transport

The generator is equipped with both manual start and an electric starter, ensuring convenient starting in various operating conditions. Low oil level protection reduces the risk of breakdowns and extends engine life, while the hour meter helps to plan timely maintenance and monitor loads.

Advantages and Applications

The SOLAX SDJ8500ME is suitable for backup power for private homes, cottages, small offices, and retail outlets. Diesel generators are generally known for their fuel efficiency and durability compared to gasoline counterparts: diesel fuel is usually cheaper, and engines have a longer service life and high torque, which is especially important for starting loads. Diesel is also less volatile than gasoline, which increases storage and operating safety.

Frequently Asked Questions

What are the advantages of diesel generators compared to gasoline generators?

Diesel generators have several key advantages:

• Economy — diesel fuel is usually cheaper, and engines are more efficient, which reduces fuel costs for the same output power.
• Reliability and durability — diesel engines are robust and designed for long-term loads, providing a longer service life.
• Safety — diesel fuel is less volatile, thus reducing the risk of ignition.
• High torque — ensures stable operation under load, especially when starting heavy consumers.

What should be considered when choosing a diesel generator?

When choosing a generator, consider the following indicators:

• Power — calculate the total power of all appliances and add a 20–30% reserve for safe operation.
• Power quality — for sensitive electronics, choose a generator with AVR.
• Fuel consumption — affects operating costs and runtime between refuels.
• Noise level — important for residential areas; check the noise level in the device specifications.
• Protection systems — the presence of low oil level protection and other systems increases operational safety.

How many hours can a diesel generator run continuously?

The duration of continuous operation depends on the load mode and fuel consumption, but for generators of this class, the average runtime on a single tank is approximately 8–10 hours.

How to correctly determine the required power of a diesel generator?

To determine the required power, sum the consumption of all appliances planned to be switched on simultaneously, and add a 20–30% reserve to compensate for starting currents and unforeseen loads.

What is automatic transfer switch (ATS) and why is it needed?

An automatic transfer switch (ATS) is a system that automatically starts the generator when there is no voltage in the main grid and switches power to the backup source. After the grid is restored, the system automatically returns power to the main source and turns off the generator. ATS is especially useful for ensuring uninterrupted power supply to critical equipment.

If you are looking for a powerful, economical, and easy-to-operate diesel generator for home or small business, the SOLAX SDJ8500ME is an excellent choice due to its design, protections, and mobility.
