The ACPCS models range from 100 kW to 500 kW in rated power, with the available models being ACPCS-100kt, ACPCS-150kt, ACPCS-200kt, ACPCS-250kt, ACPCS-300kt, and ACPCS-500kt. Each model has a rated voltage of at least 240 volts AC.

The optimal rated voltage for the generator is 450 volts AC, with a start voltage requirement of at least 180 volts AC. The device supports an AC voltage working range between 150 volts and 550 volts. Maximum AC current varies per model, from 241 amps for the smallest unit up to 1203 amps for the largest.

All models utilize lithium-ion batteries, with customizable voltage ranges to suit different applications. The nominal battery voltage can range from 400 to 900 volts DC, based on customer specifications.

The maximum charging and discharging currents also differ among models, with current values spanning from 250 amperes up to 750 amperes depending on the unit. For example, the ACPCS-100kt has a max charging/discharging current of 250A, while the ACPCS-300kt supports up to 750A.

Regarding grid-connected operation, the rated charging and discharging power corresponds to the rated power for each model, ranging from 100 kW to 500 kW. The maximum charge and discharge power exceeds the rated value, ranging from 120 kW to 600 kW depending on the model.

The rated current for charge and discharge spans from 144 amps for the 100 kW model to 433 amps for the 300 kW option, with maximum currents reaching as high as 866 amps on the highest capacity model.

The rated grid voltage is fixed at 400 volts, and the permissible grid voltage varies between 300 and 460 volts. These models operate at a frequency of either 50 or 60 Hz, ensuring compatibility with international standards.

They maintain a low current total harmonic distortion rate of less than 3% at rated power, and support a power factor greater than 0.99, with an adjustable range from -1 to 1. Additionally, the units have an overload capacity of 1.2 times the nominal power, sustained continuously for up to one minute.

Applications:

Wind turbine systems harness the power of the wind to generate electricity. By converting kinetic energy from wind into mechanical power, these turbines provide a renewable and clean source of energy. They are commonly used in wind farms, both onshore and offshore, contributing significantly to sustainable power generation worldwide.

Solar energy systems utilize sunlight to produce electrical power through photovoltaic panels or solar thermal collectors. This technology is widely adopted for residential, commercial, and industrial applications, offering an eco-friendly alternative to fossil fuels. Solar power is abundant and helps reduce greenhouse gas emissions.

Hydro systems generate electricity by harnessing the energy of flowing or falling water. This method, known as hydropower, is one of the oldest and most reliable sources of renewable energy. It involves the use of dams or run-of-the-river setups to convert water energy into electrical power, providing a consistent and large-scale energy supply.
