Advanced Hybrid Power Management System

The Growatt SPF3500/5000ES series represents cutting-edge off-grid solar technology, combining a high-efficiency pure sine wave inverter, MPPT solar charge controller, and UPS functionality in a single compact unit. The SPF3500ES delivers 3500W continuous power with 7000VA surge capacity, while the SPF5000ES provides 5000W continuous output with impressive 10000VA surge power capability.

Both models feature advanced MPPT technology with voltage ranges from 120-430VDC and maximum PV input voltage up to 450VDC, ensuring optimal solar energy harvesting across varying weather conditions. The integrated charge controller eliminates the need for separate charging equipment, with the SPF3500ES offering 80A solar charging current and the SPF5000ES providing 100A charging capacity.

Intelligent Energy Optimization Features

Experience exceptional power factor performance up to 1.0, delivering the full rated power output unlike conventional inverters with 0.8 power factors. The innovative DC/AC ratio up to 1.2 allows oversized PV arrays, with the SPF3500ES supporting up to 4.5kW solar input and the SPF5000ES handling up to 6kW PV array power.

The inverters feature multi-customized operating modes for diverse energy scenarios, including configurable grid or solar input priority settings. Advanced scheduling capabilities allow flexible timing control for charging and discharging cycles, optimizing energy usage patterns based on your specific requirements.

Professional Connectivity and Monitoring

Stay connected to your energy system with optional WiFi and GPRS remote monitoring capabilities through the ShinePhone app and PVkeeper platform. The built-in LCD display with intuitive button controls provides direct system configuration without requiring additional remote controllers.

Both models support CAN/RS485 communication protocols for seamless battery management system integration, ensuring optimal battery performance and longevity. The ultra-fast 10ms transfer time in PC mode (20ms maximum) guarantees uninterrupted power supply during grid transitions.

Robust Construction and Reliability

Engineered for demanding off-grid applications, these inverters operate efficiently in temperatures from 0°C to 55°C with 93% peak conversion efficiency. The compact design measuring 330×485×135mm and weighing only 11.5-12kg facilitates easy installation in space-constrained environments.

Enhanced protection features include overload safeguards, short circuit protection, over-temperature monitoring, PV overvoltage protection, and battery reverse polarity prevention. The IP20 protection rating ensures reliable operation in residential and light commercial environments.

Parallel scalability enables system expansion up to 30kW total capacity by connecting up to 6 units, making these inverters perfect for growing energy needs. Compatible with various battery technologies and supported by comprehensive warranty coverage, the SPF3500/5000ES series delivers professional-grade off-grid power solutions for residential, commercial, and remote applications.
