Tips What Is the Difference Between DC Power and AC Power?

AC stands for alternating current. AC voltage alternates direction, changing from a positive voltage to a negative voltage and back. The number of times it changes per second is measured in hertz (Hz). In the United States, AC power is 60 Hz, so it alternates 60 times every second. DC stands for “direct current”, which does not alternate. DC voltage always moves in one direction. A solar panel produces DC power, but your home needs AC power. This is why you need an inverter or microinverter to convert DC to AC.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
