Growatt Hybrid Solar Inverter for Optimal Home Energy Performance

Yes, the system is scalable. Start with one 16kWh battery (51.2V 314Ah) and add up to 9 more or compatible 48V lithium batteries. Two SPE 12000ES inverters support up to 250A/280A charging/discharging per unit, sufficient for multiple modules. Expand storage without replacing hardware.

Yes. The SPE 12000ES supports both singlephase and three phase configurations. With two inverters, you can operate them in split phase or single phase parallel mode (24kW total). For 3 phase 230/400V output (e.g., for commercial equipment or large homes), add a third SPE 12000ES inverter. The system can output standard 3 phase AC power. Parallel operation is straightforward with built-in transfer switch and communication ports.

The system ensures uninterrupted or near-uninterrupted backup power. In single inverter use, switch time is <20ms. With two in parallel, switch time is <30ms. This keeps sensitive electronics (computers, routers, fridges, LEDs) running smoothly. Built-in transfer switch means no extra hardware is needed.

A single 12kW unit can be paralleled up to 9 units, achieving a maximum total capacity of 108kW. This makes it suitable for large homes or small commercial sites with high energy demands.

The inverter supports Lithium, Lead-acid, and Gel batteries. It features a nominal DC voltage of 48V and high charging/discharging currents (up to 250A/280A depending on the model) to handle various battery types effectively.
