Product Q&A

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

Yes, easily scalable. Start with one 16kWh battery, add up to 9 more (or compatible 48V lithium). Two SPE 12000ES inverters support up to 250A/280A current per unit. Expand storage without replacing hardware.

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

Yes. SPE 12000ES supports singlephase and three phase configurations. Operate in split phase or single phase parallel mode (24kW total). For 3 phase 230/400V, add a third inverter. Configure for 3 phase AC power. Parallel operation is simple, supported by internal switch and ports.

Q:How does the system switch to battery backup when grid fails? Any downtime?

Provides near uninterrupted power. Single inverter switch time <20ms, parallel <30ms. Keeps sensitive electronics running smoothly. No flicker or reset. Built-in transfer switch, no external hardware needed.

Q:What is the maximum DC input voltage and MPPT voltage range?

The maximum recommended PV power is up to 15000W for the 12000W model. Max DC voltage is 550V, and the MPP voltage range is 60V-480V.

Q:What types of batteries are compatible with this inverter?

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