Technical FAQs 4

Do solar panels use AC or DC?

Solar panels generate DC (Direct Current) electricity when sunlight hits them. However, homes and the electrical grid use AC (Alternating Current). This difference means that, in most solar systems, the DC power produced by your solar panels must be converted into AC for use in your home or to send back to the grid. That’s where inverters come in.

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 battery?

A DC-connected energy storage system connects to the grid mains at the same place as the solar panels; this usually means that they share a ‘hybrid’ inverter. You can think of this as a ‘one box’ solution, because there is only one inverter instead of two.

What type of electricity does a solar panel use?

Alternating current (AC) is the type of electricity used to power your home. The large majority of household appliances use AC electricity. Solar panels, however, generate power in direct current (DC) form. This is also how batteries store electricity. Not just solar batteries, either - even your iPhone needs to convert AC to DC when charging.
