The PV Power Unit is a solar cell simulation power supply device used for evaluation tests of solar power inverters. This unit can output 2.4[kW] and generates a fixed DC output based on the simulated characteristics of solar cells (I-V curve simulation). The voltage and current output values can be changed during output, and by connecting to computer software, it is possible to monitor the operating point of the power inverter. By communicating with measuring instruments such as power meters, it becomes possible to observe the input and output of the power inverter, and data can be saved every second using the computer software, making it an optimal system for long-term tests and scheduling tests. 【Features】 ●Used for evaluation tests of solar power inverters ● A solar cell simulation power supply capable of 2.4[kW] output ● Generates a fixed DC output based on the simulated characteristics of solar cells ● Voltage and current output values can be changed during output ● Data can be saved every second using computer software *For more details, please contact us or download the catalog. *Demo units are also available for loan, so please get in touch.

The PVP01301 is a simulated power source used to confirm the operation of power conditioners at solar power installation sites and during inspections before delivery. It outputs fixed solar cell simulated characteristics (I-V curve/DC). With a lightweight and compact design that is portable, it offers simple operation. It allows for operation checks of the power conditioner even at night or in bad weather. 【Features】 - Portable compact design - Simple operability (easy operation with lever ON to start output) - Allows for operation checks of the power conditioner even at night or during rain when solar cells do not generate power (please confirm the DC input operating range of the power conditioner in advance due to fixed output) *For more details, please refer to the PDF document or feel free to contact us.

The "MEP12281/MEP12282" is a power supply device that simulates the output of solar cells (I-V curve). In addition to simulating solar cells, it can also operate as a fuel cell simulator and provide constant voltage output. The configuration consists of a 300W simulated module that can be connected in series or parallel using patch cords, allowing for I-V curve settings for each module. It faithfully reproduces the electrical equivalent circuit of solar cells, enabling a simulation that is closer to reality compared to traditional methods that simulate the entire array as a whole. Remote operation also allows for scheduled operations, making the simulation even more realistic. 【Features】 ■ Composed of 5 modules, it can be housed in a 3U 19-inch JIS rack. ■ The system can be expanded by adding units and connecting them in series or parallel. ■ Since output can be generated for each module, it is compatible with tests for microinverters and other devices. ■ Output voltage and current are displayed on the main unit's LED for each module. ■ It can be operated independently or remotely by connecting to a PC. *For more details, please refer to the PDF document or feel free to contact us. *Demo units are also available for loan, so please get in touch.
