PHOTON, respected by international organizations, tested Growatt inverters and expressed its great respect. It has a leading position among the one-phase inverters with the 97,1% efficiency achieved. The three phase inverters reach the efficiency of 98%.
The speciality of Growatt inverters is that they are able to keep their high efficiency within a wide range of voltage. Compared to inverters of other producers Growatt inverters can start earlier in the morning hours and last the energy production longer in the evening. This characteristic makes it capable of building in a so called “Future Proof” system. The system is fully operational with PV solar panels less than its maximum capacity so it can be extended with more panels in the future.
