What is the difference between 1000v and 1500V power generation system?

Compared with traditional 1000V DC voltage system, 1500V system has less connections between sting arrays and inverter. The PV arrays are constructed in the form of strings and then connect with the combiners in parallel, DC cabinet, inverter and power grid in sequence. Diagram 1: PV Power Generation System

What is a 1500 volt PV system?

III. 1500V System Solution The PV power system usually takes power from either AC grid power or high-voltage DC battery. The former needs to a long wire to connect the AC power because it is usually installed in a sunny position in remote areas, which greatly increases the costs. Therefore, taking power from high-voltage DC battery is more popular.

How can a 1500V system reduce design cost?

Another measure for design cost reduction comes from less components. 1500V system expands single-string components from 22 to 32, superior to 1000V system, reducing the quantities of strings and inverter, combiners and DC-side cables.

How does a 1500 volt inverter work?

Raising the system voltage to 1500 volts allows for 50 percent longer strings which eliminates 33 percent of the combiners and wiring in a system. This also enables inverter manufacturers to increase the rated output power of inverters by 10 to 40 percent.

Which equipment suppliers are making the move to 1500 volts?

Some equipment suppliers – PV module, inverter, electrical wiring, combiner box, fuse and other component manufactures – are now starting to make available 1500 volt products to support system designers who are making the move to 1500 volts.

What is the difference between 1000 Volt and 1500 volt?

Both approaches result in lower total CAPEX compared to basic 1000 volt system designs. Since moving to higher voltages reduces costs, there is a fast-growing interest in and early deployment of large scale systems that are 1500 volts rather than 1000 volts.
