GROWATT SPF 3500 ES Off Grid 3.5KW 48V Big PV Input

This is a multifunctional off grid solar inverter, integrated with a MPPT solar charge controller, a high frequency pure sine wave inverter and a UPS function module in one machine, which is perfect for off grid backup power and self-consumption apps This inverter can work with or without batteries. The whole system also need other devices to achieve complete running such as PV modules, generator, or utility grid The WiFi / GPRS module is a plug-and-play monitoring device to be installed on the inverter. With this device, users can monitor the status of the PV system from the mobile phone or from the website anytime anywhere. Parallel operation up to 6 unit (only with battery connected) The MPPT charge controller lowers the voltage of panels to the required level to charge the battery. The current is raised with the same ratio the voltage is lowered. This continuously happens during the day to optimize the use of energy. This is dependent on the power of the sun, the angle and the temperature and health of the panels. The charge controller also makes sure the battery will not be overcharged, but also not fully discharged.
