Good news for those who are planning an off-grid solar PV system. Growatt has combined unique technology and design concept into Growatt SPF3000/5000 series as a new solution to provide power independently and cost-effectively where there is no grid, especially in rural villages and isolated islands. Growatt SPF3000/5000 series is perfect for off-grid, backup power and self-consumption applications. Also stacking two charge controller units will double the system’s charging power to be compatible with larger capacity battery.
To get a good experience for the users, SPF3000/5000 appearance is stylish, not only local graphical LCD and four buttons, but also compact design (12.5KG@482*450*140 mm), even source priority to charge battery and power load are programmable. Thanks to its design, SPF3000/5000 is scalable. The maximum number of units in parallel is up to 6, and suitable for single phase and three phase system. Charging power is increasable by adding expansion charge controller unit. To ensure off-grid PV system work in a higher efficient way, SPF3000/5000 is built-in two MPPT for more yields, and compatible with lead-acid and lithium-ion battery, also supports utility grid and generator voltage input.
