Product Description Growatt Growatt SPF 3500 ES Off-Grid
InverterThe Growatt SPF 3000 ES is an inverter that can operate
both with and without a battery. The maximum input voltage is
450VDC.Integration of an MPPT charge controller optimizes charging
and discharging of the battery, making it last as long as possible.
Priority can be given to charging via the grid or the connected PV
system.MonitoringThe system can also be remotely monitored using a
WiFi or GPRS dongle. Parallel scaling is supported.Charge
controllerThe 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.Capacity expansionThe system's capacity can be expanded
up to 30kW by combining a total of six of these units in parallel
operation. Product Parameters Datasheet SPF 3500 ES SPF
