Product Q&A

Q:Can I add more batteries to this system in the future?

Yes, the system is designed for easy scalability. Start with one 16kWh battery (51.2V 314Ah), and add up to 9 more identical or compatible 48V lithium batteries in parallel. The two SPE 12000ES inverters support a charging/discharging current of 250A/280A per unit, enough for multiple battery modules. Expand storage capacity without replacing hardware.

Q:Can these two inverters work in parallel to provide 3 phase output?

Yes. The SPE 12000ES supports both singlephase and three phase configurations. Operate them in split phase or single phase parallel mode (24kW total). For a 3 phase 230/400V output, add a third SPE 12000ES inverter. Configure for standard 3 phase AC power. Parallel operation is straightforward with the internal transfer switch and communication ports.

Q:How does the system switch to battery backup when the grid fails? Is there any downtime?

The system provides uninterrupted backup power. In single inverter, switch time is <20ms. With two inverters, switch time is <30ms, keeping sensitive electronics running without interruption. No flicker or reset. The automatic transfer switch is built into each inverter; no external hardware needed.

Q:What is the maximum parallel capacity for this inverter?

The single 12kW unit can be paralleled up to 108kW, making it suitable for large homes or small commercial expansion.

Q:What battery types are compatible with this hybrid inverter?

The inverter supports Lithium, Lead-acid, and Gel batteries, providing flexibility for different energy storage needs.
