u-power

u-power 48000W Peak 12000W Power Inverter 12V 110V 220V 60Hz Split Phase Pure Sine Wave UPS Charger LCD

SKU CH-XQ9H-27KCB

Converts 12 V DC to 110 V and 220 V AC split-phase pure sine wave with 12000 W continuous and 48000 W peak power, plus built-in UPS, charger and LCD display

  • Delivers 12000 W continuous split-phase power for whole-home backup
  • Handles 48000 W peak surges to start heavy motor loads
  • Supplies both 110 V and 220 V simultaneously from one unit
  • Pure sine-wave output protects sensitive electronics and appliances
  • Built-in UPS charger and LCD display simplify battery management

12 V split-phase inverter for off-grid

This u-power unit converts 12 V DC into 110 V and 220 V AC at 60 Hz using a low-frequency pure sine wave design. It delivers 12000 W continuous output split as 6000 W on each voltage leg, with a 48000 W peak rating for motor starts. The integrated UPS charger and LCD display suit solar, mobile or standby installations.

UPS charger and LCD monitoring change daily

The built-in charger maintains the battery bank while grid or generator power is present, then switches to inverter mode without interruption when that source fails. The LCD reports voltage, current and wattage for the 110 V leg directly; 220 V readings show half the actual values unless both legs are loaded evenly.

12 V DC input fixes the battery bank voltage

Only 12 V battery strings can be connected, so systems built around 24 V or 48 V banks cannot use this inverter without re-wiring. Buyers who need a higher DC bus voltage must select a different model.

Questions about this item

What maintenance or replacement will the internal battery charger need over time?

The built-in battery charger is part of the control board; if it fails the board must be replaced, and the supplier notes a custom board is required for full 220V LCD readout.

Which limit appears first when running both 110V and 220V loads continuously?

The combined continuous rating is 6000W; drawing more than that on the split-phase output triggers the protection circuit before the 24000W peak rating is reached.

How much heat and fan noise should I expect when the inverter runs all day at 6000W?

The low-frequency transformer design generates noticeable heat at full load, so forced-air cooling runs continuously; expect warm exhaust and audible fan noise in a confined space.
