3.5kVA Growatt SPF-3500 ES Lite Single-Phase Inverter – 48V

The 3.5kVA Growatt SPF-3500 ES Lite Single-Phase Inverter is a compact 48V inverter solution designed for residential solar, battery-storage and backup-power applications.

Its 3.5kVA capacity makes it particularly suitable for smaller home and office installations where essential electrical loads need to be powered without installing an unnecessarily large inverter system.

Operating on a 48V battery platform, the SPF-3500 ES Lite can be integrated with a correctly matched battery bank to store energy for use at night, during periods of reduced solar production or during grid interruptions.

The combination of Growatt technology, 3.5kVA capacity and a 48V architecture makes the SPF-3500 ES Lite a practical choice for customers building compact solar and backup systems around appropriately assessed loads.

Why the 3.5kVA Capacity Stands Out

The 3.5kVA capacity positions the Growatt SPF-3500 ES Lite as a practical inverter for customers who need more than basic low-power backup without immediately moving to a larger 5kVA or 6kVA-class system.

It is particularly useful for essential household and small-office loads, provided their combined operating and starting requirements remain within the inverter’s capabilities.

Equipment with high starting currents, including pumps, refrigerators, compressors and other motor-driven appliances, should be assessed separately during system sizing.

48V Battery System Advantage

The 48V battery architecture is an important feature of the SPF-3500 ES Lite.

A correctly matched 48V battery system provides the energy-storage platform needed for solar self-consumption and backup-power applications.

For lithium battery installations, compatibility between the inverter and battery—including voltage, charging parameters and any required communication—should be confirmed before installation.

Single-Phase Advantage

The single-phase configuration makes this inverter particularly relevant to residential properties and smaller commercial premises operating on single-phase electrical systems.

Correct integration with the property’s electrical installation, protection equipment and backup circuits should be completed by a qualified solar technician.

Solar & Backup Power Advantage

When incorporated into a properly designed solar system, the Growatt SPF-3500 ES Lite can form the central power-conversion component connecting compatible solar generation, battery storage and selected electrical loads.

Available energy can be used to support loads and charge compatible batteries according to the final system configuration.

Stored battery energy can then be available for night-time consumption or backup operation when required.

Usage & Installation Notes

• Conduct a load assessment before installation
• Use a correctly matched 48V battery system
• Confirm lithium battery compatibility where applicable
• Correctly size any connected solar PV array
• Verify the manufacturer’s PV input specifications
• Use appropriately rated DC cables
• Install suitable battery and PV isolation
• Provide correct AC input and output protection
• Ensure proper system earthing
• Configure battery charging parameters correctly
• Assess high-starting-current appliances separately
• Professional installation is recommended

Mini FAQ

What is the inverter capacity?
