Product Q&A

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

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

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

Yes. The SPE 12000ES supports both singlephase and three phase configurations. With two inverters, you can operate in split phase or single phase parallel mode (24kW total). Add a third SPE 12000ES for 3 phase 230/400V output for commercial or large homes. The system configures to standard 3 phase AC power, supported by the transfer switch and ports.

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

The system ensures uninterrupted power. In single inverter mode, switch time is under 20ms. With two inverters, it's under 30ms, keeping sensitive electronics running without interruption. No flicker or reset occurs. Built-in transfer switch; no external hardware needed.

Q:What is the warranty period for this inverter?

We provide a 5-year warranty for this bidirectional inverter.

Q:What certifications does this product have?

This product is certified with CE and ROHS standards.
