The 2U inverter family is one of the highest energy density inverter products on the market thanks to its unique controller algorithm, high-frequency technology and state-of-the-art semiconductors. The user can program in the inverter that the primary source must be the battery or the network. In this way, an inverter can be built online or offline. If the primary source is inadequate or defective in any respect, the electronic switch will automatically switch to the secondary input.
