## Summary description

Growatt SPF3500ES is a 3.5 kW single-phase inverter with a 48 V DC input designed for residential and small commercial solar systems and backup power. It converts DC from batteries or PV arrays to AC for household loads, provides reliable power supply, supports battery-based installations, and enables integration with off-grid or hybrid setups to ensure continuous electricity.

## Long description

Growatt SPF3500ES is a multifunctional 3.5 kW single-phase inverter designed for residential and small commercial solar systems and backup power. It integrates an 80A MPPT solar charge controller, inverter and AC battery charger in a compact housing and supports 48V battery banks. The unit accepts PV array input up to 4.5 kW with a maximum open-circuit PV voltage of 450 V and an MPPT operating range of 120–430 V. The inverter provides pure sine wave output, supports parallel operation up to 6 units (expandable to 30 kW) and includes an LCD for parameter settings and charger priority configuration.
Advantages
The Growatt SPF3500ES combines inverter, MPPT solar charger and AC charger functions in a single device, enabling uninterrupted power supply from solar, battery or grid. Its 80A MPPT controller maximises PV yield within the 120–430 V MPPT window while supporting up to 4.5 kW of PV power. Compact dimensions and parallel capability allow easy capacity expansion. Built-in monitoring options (USB, Wi‑Fi/GPRS, RS485) and compatibility with the Growatt Shine WiFi-F interface provide remote status and configuration. The inverter offers pure sine wave output, selectable charging priorities and generator compatibility for flexible installations.
Suitable for (tasks / use cases)
Residential solar systems with 48V battery banks
Small commercial premises requiring backup power
Hybrid on-grid/off-grid installations with PV and battery integration
Scenarios needing scalable capacity via parallel operation (up to 6 units)

How to use
Install the Growatt SPF3500ES according to local electrical codes and the manufacturer’s installation guide. Connect the PV array to the PV input observing polarity and MPPT voltage limits (120–430 V operating, max 450 V open-circuit). Connect a 48 V battery bank of appropriate type (lithium or lead‑acid) and the AC input for grid or generator supply. Use the LCD to set operating parameters, charge priorities and selectable AC voltage ranges. For expanded capacity, configure parallel operation and ensure identical settings across all units.
Usage recommendations
Provide dedicated grounding for the PV array separate from the building grounding and install lightning protection and overvoltage limiters on input circuits as required. Register the serial number, purchase invoice and certified electrician documentation to validate the 24‑month warranty. Note that lightning strikes are excluded from warranty coverage and should be handled via insurance.
