The E-Series is the next generation of low power, three phase residential inverters from SolarEdge. Featuring multiple design improvements, the E-Series is smaller, lighter and easier to install than previous models.  Suitable for both outdoor and indoor installations, these inverters operate even quieter than before following removal of the external fan combined with an upgraded internal fan.  The E-Series is offered in the following sizes, with the standard SolarEdge 12-year warranty: 4kW, 5kW, 7kW and 8kW. E-Series inverters are also available with a built-in GSM cellular modem.
