Growatt SPF 3500 ES

(1 customer review)


An off-grid inverter with an integrated charge controller is the Growatt SPF 3500ES. Therefore, using batteries in addition to it is an option but not required. Even without a battery, it functions properly.

The inbuilt charge controller’s benefit is regulating the battery’s charging and discharging. On this Growatt SPF inverter, priorities may be specified. Additionally, the charge controller ensures the battery’s life is prolonged.

 This is due to the charge controller monitoring the battery’s charging current. As a result, it offers constant current adjustment. The battery is never entirely depleted or overcharged. You can connect a maximum of 4500wp to it, which is suitable for a 48Volt battery: Growatt ARK low voltage.

Key features

  • MPPT charge controller built-in.
  • Charge function for equalization.
