Description

Growatt SPF 3500 ES is a powerful off-grid inverter for anyone running an off-grid solar system or looking to flexibly manage their self-consumption. With a continuous power output of 3500 W, an integrated MPPT charge controller, and a PV input of up to 450 VDC, the device is ideal for single-phase operation of self-sufficient power supplies.

Key Benefits for Your System

Flexible operation: The Growatt SPF 3500 ES works either with or without a battery, adapting to your solar system.
Integrated MPPT charge controller: The built-in charge controller technology gets the maximum output from your photovoltaic modules.
Expandable via parallel connection: Up to 6 units can be operated in parallel to expand the capacity of your system.
Pure sine wave: The clean output power reliably and safely supplies even sensitive appliances.

Intelligent Use of Your Solar Power

A modern off-grid inverter ensures you can optimally use your solar power even independently of the public grid. The Growatt SPF 3500 ES can be configured to prioritize solar or grid power, and automatically draws from the grid if PV energy is insufficient. You can flexibly schedule charging and discharging times, allowing you to specifically control the self-consumption of your photovoltaic system. Optionally, the device can be monitored remotely via WIFI or GPRS, so you always have an eye on all important values. This way, you gain a significant degree of independence and reduce your electricity costs – whether at home, in a vacation home, or in off-grid applications.
