The PRIMO inverter with a single-phase grid connection is intended solely as a replacement inverter for existing systems that require a replacement for inverters compliant with VDE 0126-1-1 (ENS standard). This inverter is not certified for the Low Voltage Directive (VDE-AR-N 4105) in Germany, and therefore, the use of the Primo in new installations in Germany is not permitted. It features an integrated DC disconnect switch, is suitable for indoor and outdoor installation, and has an ambient temperature range of -40 °C to +55 °C. The inverter offers Wi-Fi, Ethernet LAN, and a web server, 6 inputs as well as 4 digital input/output connections for connecting round control receivers, a USB Type A port, 2x RS422 (RJ45 socket), an S0 input, a reporting output, and an efficiency of 98%.
