Product details

The Growatt inverters of the MID series are particularly well-suited for larger PV systems without storage. They can be used for self-supply or as full feed-in systems. The maximum output power of the inverter is 20,000 W, and the device is compatible with a photovoltaic system with a maximum size of 30 kWp. The maximum efficiency of the inverter is 98.3%. The European efficiency of 97.5% takes into account typical weather conditions in Europe. The Growatt MID 20KTL3-X1 is transformerless, which makes it particularly efficient. The inverter includes 3 MPP trackers, allowing for 3 independent strings to be connected. This is important when the PV system consists of differently arranged areas, such as in an east-west orientation. A 3-phase smart meter is required for the operation of the Growatt MID 20KTL3-X1 and is not included in the delivery. High safety is a key aspect and is achieved through several features such as a built-in DC switch, surge protection, reverse polarity protection, and many other protective mechanisms.
