The SE9kUS and SE14.4kUS inverters have a fixed input voltage of 400 VDC, while the SE10kUS, SE20kUS, and SE33.3kUS inverters operate with fixed input voltage of 850 VDC. The fixed input voltage from the optimizers allows for longer module string lengths, resulting in less wire line losses and fewer system components. These wall-mountable inverters are lightweight, and have built in module-level monitoring. They include an integrated code-compliant DC disconnect, Ethernet interface, and RS-485 serial port. All SolarEdge inverters are listed to UL 1741 and UL 1699B for the U.S.A. and Canada and are NEMA 3R rated. The inverters are rated for use from -4 F to 140 deg F temperatures. The SE14.4kUS and the SE33.3kUS inverters also come with three fused DC+ and DC- inputs, eliminating the need for a third-party fused combiner box. The optimizers automatically shut down the DC current and voltage when detecting excessive heat, or when the SolarEdge inverter is turned off or disconnected from the grid, to ensure installer and firefighter safety. The high fixed voltage of a SolarEdge commercial system enables longer DC strings to be wired, lowering installation, connection, and wiring costs over typical commercial string inverter systems. Monitoring through the SolarEdge monitoring portal can be enabled by connecting the inverter directly to an Internet router or switch, or using the wireless SolarEdge Zigbee Gateway Kit and Slave Modules. Commercial systems also can be equipped with the SolarEdge Environmental Sensors (irradiance, module and ambient temperature, and wind), as well as the Firefighter Gateway to improve safety in an emergency if needed or required.
