Growatt SPF5000-ES – 5kW Off-Grid Solar Inverter with Wi-Fi & Parallel Support

High-Performance Inverter | 5kW PV Input | Battery Optional | Wi-Fi Monitoring

The Growatt SPF5000-ES is a feature-rich off-grid inverter that supports solar-only systems or hybrid setups with optional battery storage. Designed for efficient, reliable energy management, it offers a wide MPPT voltage range (120V–450V), making it ideal for high-voltage solar arrays.

The inverter works with or without battery - Make sure that you have over 8 panels in series to run reliably the inverter without battery

It includes a Wi-Fi USB stick for real-time monitoring and is parallel-ready for systems up to 30kW. With its advanced hybrid mode, this inverter can combine power from the grid and solar simultaneously — even when battery reserves are low — without switching instantly to bypass mode.

Key Benefits

• ✅ 5kW rated power output (5000VA)
• ✅ Works with or without a battery
• ✅ Wi-Fi dongle included for monitoring
• ✅ Parallel operation – up to 6 inverters (30kW)
• ✅ Advanced 100A MPPT solar charge controller
• ✅ PV and grid can power loads together
• ✅ Scheduled charging and priority input settings
• ✅ Equalisation function to extend battery lifespan

Recommended Setup

To achieve stable battery-less operation, use a solar array between 300V and 350V. We recommend a minimum of six 300W–500W solar panels.
