FAQ

Common Questions

Can I use this as a UPS for critical loads?

Yes — it switches in as fast as 10ms in UPS mode (20ms for general appliances), fast enough to keep sensitive electronics running through a power interruption.

What battery types does it support?

AGM, Gel, Flooded, and lithium batteries, with battery-specific bulk charging voltages (58.4Vdc for flooded, 56.4Vdc for AGM/Gel) and configurable charging current.

Can multiple units be combined for more power?

Yes — up to 6 units can be paralleled for expanded capacity, including split-phase configurations for larger loads.

Does it work with a generator?

Yes — it accepts both utility mains and generator input, and automatically restores normal operation once utility power returns.

Can I buy it bundled with a battery?

Yes — beyond the standalone unit, it's also available as a 2-unit pack, or bundled with 1, 2, or 3 ALPHA 5 PRO batteries.

How is this different from the NOVA 12K?

The NOVA 12K is a larger, higher-output hybrid inverter; the NOVA 6548 is sized for smaller off-grid systems or as a building block in a paralleled multi-unit setup.
