US-based Tigo Energy has signed a certificate confirming the compatibility of its TS4 Flex MLPE (Module Level Power Electronics)device family with hybrid inverters from Haier Energy. The certification covers selected single-phase and three-phase inverter models and allows for integration when designed and installed correctly. According to Haier Energy, this collaboration expands its technical portfolio and enhances installation flexibility across varied plant conditions. Tigo Energy stated that such interoperability improves system efficiency and offers residential users smarter energy control. These countries represent over half of the EU’s top ten in solar capacity per capita, supported by long-term policies under the EU National Energy and Climate Plan Framework and Social Climate Fund. Installers in Austria, Belgium, Germany, Italy, Luxembourg, the Netherlands, and Switzerland have been invited to participate in a joint multilingual webinar. Recently, Tigo Energyhas launched its 725 W TS4-A MLPE devices with rapid shutdown, energy harvesting, and backward compatibility features.
