Combined Energy Device Installation Location
To convert direct current into alternating current, a CH-4000W inverter manufactured by
the Republic of China was used.
Lighting systems for the area where the family business is located, a refrigerator, an
electric stove for cooking, video surveillance devices and modem devices for connecting to
the Internet were connected, that is, a load with a total power of 3796 W.
The operating modes of the loads are shown in Table 1. Since there was no need for a
daylighting system, electric lamps were used in the evenings. Loads such as a video
surveillance system, a modem device, and a refrigerator worked constantly connected.
During the day, the main load was the electric stove for cooking, and it worked for more than
10 hours. When measuring the electricity supplied by the inverter with an electric meter in
the period from 08:00 to 19:00, it was found that 30 kWh of electricity was supplied.

From 19:00 in the evening until 08:00 in the morning, the combined energy device began
to operate with a maximum load of 1296 W. The electricity generated by the Archimedes
screw turbine was used to power consumers through an inverter and to charge the batteries,
delivering a total of 10 kWh of electricity.
Using measuring instruments, the daily values of the output voltage and current of the
solar power plant and micro-hydroelectric power station were determined. The graph of daily
capacity utilization of KUE is shown in Figure 7.
