Technical FAQs 4

How does a DC power system work?

Most renewable energy sources, such as solar panels and wind turbines, generate electricity in DC. Similarly, energy storage systems like batteries operate in DC. Using DC systems to connect these sources directly to DC loads eliminates the need for multiple energy conversions, reducing losses and improving overall system efficiency.

What is DC-coupled solar power storage?

In traditional solar power storage systems, energy from solar panels is converted from DC (direct current) to AC (alternating current) for immediate use or to be sent back to the grid. DC-Coupled Storage, on the other hand, maintains the energy in its native DC form, storing it directly in batteries.

What is a DC-coupled Solar System?

DC-Coupled system ties the PV array and battery storage system together on the DC-side of the inverter, requiring all assets to be appropriately and similarly sized in order for optimized energy storage and power flow. Mid to large-scale solar is a non-reversible trend in the energy mix of the U.S. and world.

Is DC a good choice for a new energy landscape?

DC’s compatibility with renewables makes it the forward-looking choice for the new energy landscape. Most renewable energy sources, such as solar panels and wind turbines, generate electricity in DC. Similarly, energy storage systems like batteries operate in DC.
