Growatt SPE 8000 – 12000 ES

Growatt SPE 8000-12000 ES are state-of-the-art off-grid storage inverters for backup power and self-consumption. This inverter charges storage batteries from both solar photovoltaic (PV) and two AC sources with integrated transfer switches. It powers loads directly from a solar PV array without charging and discharging the battery. As such, there is no micro-cycling of the battery system.

This inverter is ideal for homeowners with large energy needs, residential solar-plus-storage installations, and users seeking smart, scalable backup power solutions.

In particular, the Growatt SPE 12000 ES is the most powerful model in Growatt’s SPE single-phase hybrid inverter series, offering 12 kW of AC output power.

Key Features

• High Output Power: With 12,000W AC power, the SPE 12000 ES is ideal for larger households or prosumers with high energy usage or EV charging needs.
• The SPE 8000 ES outputs 8kW AC power while the SPE 10000 ES outputs 10kW of AC power which are also ideal choices for residential and small commercial buildings.
• Dual MPPT Inputs: Supports two independent solar strings with a wide MPPT voltage range (60V–480V).
• Maximum PV inputs of 10kW (SPE 8000 ES), 12.5kW (SPE 10000 ES), & 15.6kW (SPE 12000 ES), maximizing solar harvest from different roof orientations.
• Battery Integration: Compatible with 48V lithium-ion and lead-acid batteries for energy storage, time-of-use optimization, and backup power.
• Backup Power Ready: Seamless switch to backup mode within <20 ms, ensuring critical loads remain powered during grid outages.
• Parallel System Support: Up to 9 inverters can be installed in parallel, enabling system expansion up to 108 kW for advanced setups.
• Smart Monitoring & Control: Built-in WiFi, 4G (optional), and integration with Growatt Shine Server for real-time system monitoring and remote diagnostics.

This user-friendly interface allows for convenient management of the user’s solar energy system, ensuring efficient energy usage and enhanced savings. An LCD screen and buttons are built into the inverter allowing users to directly configure their off-grid sustainable energy systems. Users also have the option to remotely monitor their off-grid PV systems.

Its ability to operate in off-grid mode with battery backup ensures uninterrupted power supply, making it an ideal choice for areas with unstable grid connections or remote locations.
