Frequently Asked Questions
What’s the difference between the EFDPUPCS-BP and the standalone DELTA Pro Ultra?
The EFDPUPCS-BP includes the inverter plus one extra battery (6kWh total); the standalone inverter (EFDeltaProUltra-US) ships without a battery and requires at least one battery pack to operate.
What does 0ms UPS mean?
Unlike generators (which take seconds to start) or even other battery systems (20ms+), the DELTA Pro Ultra operates as an online UPS — it constantly conditions power, so there is literally no gap when switching from grid to battery during an outage.
Can this power a whole house?
With 3 inverters (21.6kW output) and the Smart Home Panel 2, it can power all standard household circuits including HVAC, water heaters, and EV chargers — effectively replacing a whole-home standby generator.
What battery chemistry does it use?
LFP (lithium iron phosphate) — more thermally stable and longer-lasting than NMC lithium, rated for thousands of charge cycles.
