Growatt announces new PV inverter for off-grid applications

By Growatt

Growatt has announced the launch of its latest SPF 6000 ES Plus inverter for residential off-grid PV storage applications. Targeting markets with  frequent power outages or limited grid access, the product provides significant upgrades on the company’s previous off-grid solution, the SPF 3000-5000 ES.

With a maximum PV input power of 8000W and an input voltage of up to 500V, the device enables connections to more PV modules on each string and reduces the cost of parallel connections. The inverter’s string input current reaches up to 16A, making it compatible with 500W+ large power PV modules, and dual MPP trackers for houses with multiple rooftop areas support installation at different orientations and higher energy generation.

In terms of performance and reliability, the new product has a power factor of 1.0, enabling the system to draw a power output of 6kW for the loads and 2kW for charging the battery when there is sufficient solar energy. Its dust-proof design also prevents faults caused by excessive dust and improves product reliability, making maintenance easier while extending its operational lifespan.

Enhancements have been added for easier and lower-cost installation, featuring an integrated ATS (automatic transfer switch) device and two AC terminals for power input from the utility and generator. Additionally, plug-and-play PV terminals make installations more efficient and time-saving for installers.
