Description

Growatt SPF 3500ES 3.5kW 48V Hybrid Inverter – Versatile Off-Grid Power

Unlock energy independence with the Growatt SPF 3500ES, a 3.5kW 48V hybrid inverter tailored for off-grid and backup power in homes and small businesses. Combining a high-frequency pure sine wave inverter, 80A MPPT solar charge controller, and UPS functionality, this multifunctional system supports battery-free operation and parallel scalability up to 30kW (6 units). With configurable input priority and optional WiFi monitoring, it’s a reliable, cost-effective choice for solar self-consumption—backed by Growatt’s global leadership in smart energy solutions.

Why Choose the Growatt SPF 3500ES Inverter?

• Flexible Hybrid Operation: Supports solar (4500W max PV), grid (230VAC), or generator inputs, with configurable priority (solar/battery/grid) and joint PV-grid load powering when PV is insufficient.
• Efficient Power Delivery: Provides 3.5kW (3500VA) continuous output with 7kVA surge capacity, 93% peak efficiency, and pure sine wave for sensitive electronics.
• Advanced MPPT Controller: Optimizes solar harvest with a 120-430VDC MPPT range, 450VDC max open-circuit voltage, and 80A max solar charge current.
• Smart Monitoring: Optional WiFi/GPRS module enables real-time tracking via the ShinePhone app (iOS/Android), with LCD display and buttons for easy configuration.
• Robust Features: Supports 48V lithium/lead-acid batteries, battery-free mode, equalization charging, and parallel operation (up to 6 units), with protections for overload, short-circuit, and overvoltage.

Easy Installation, Durable Design

The Growatt SPF 3500ES measures 330 x 485 x 135 mm, weighs 11.5 kg, and operates from 0°C to +50°C. It supports 48VDC battery systems (LiFePO4, lead-acid, AGM, gel) with a 60A battery charge current and CAN/RS485 for BMS communication. Install by certified electricians using MC4 connectors for PV input (4500W max) and AC terminals. Ensuring proper grounding and ventilation (2AWG cable, 2Nm torque). The inverter offers a <10ms transfer time for UPS functionality and outputs 230VAC (not 120VAC).
