u-power 32000W Peak 8000W Power Inverter 12V DC to 110V 220V AC 60Hz Split Phase Pure Sine Wave

SKU CH-4CV8-S5KNG

Converts 12 V DC into split-phase 110 V and 220 V AC at 60 Hz, delivering 4000 W continuous and 16000 W peak on each leg with pure sine wave output

  • 32000W peak power handles heavy motor starts
  • 8000W continuous output runs RV appliances and tools
  • Split-phase design delivers 110V and 220V simultaneously
  • Pure sine wave protects sensitive electronics
  • Power-save mode drops idle draw to near zero

12V Split-Phase Pure Sine Inverter

This new u-power inverter converts 12V DC battery power into 110V and 220V AC at 60Hz using low-frequency split-phase topology. It delivers 4000W continuous power on each voltage leg with a combined peak capacity of 16000W. The unit is built with stainless-steel construction that avoids spray paint for reduced environmental impact. It suits off-grid, RV and mobile tool applications needing clean waveform output.

For dual-voltage off-grid loads.

Buyers running simultaneous 110V and 220V circuits from a single battery bank gain flexible split-phase distribution without stacking inverters. The pure sine output safely powers sensitive electronics and variable-speed drives. Installers needing an integrated battery charger or UPS transfer relay must source those functions separately. The 1000W peak limit on the 220V-only leg rules out large inductive motor starts on that output alone.

1000W peak on 220V-only leg

When the 220V output (L1+L2) is used without drawing from the 110V legs, its peak surge rating is 1000W rather than the 16000W available in combined or 110V-only operation. This single constraint determines whether a specific 220V load can start reliably. Verify the locked-rotor amp draw of every 220V device against this 1000W peak figure before purchase.

Questions about this item

What AC output standard does the split-phase 12 V inverter provide and what continuous power does it cap at?

The inverter delivers split-phase 110 V and 220 V AC at 60 Hz, with 4000 W continuous power on each voltage and 4000 W combined when both are used together.

What battery voltage and cable gauge does the low-frequency pure sine wave unit require for safe operation?

It runs from a 12 V DC source; use heavy-gauge cables rated for the 8000 W peak draw and keep runs as short as possible to limit voltage drop.

How do I wire the L1, L2 and N terminals for 110 V and 220 V loads, and which step is most often missed?

Connect L1–N or L2–N for 110 V circuits and L1–L2 for 220 V circuits; the step most often missed is bonding neutral to ground at the distribution panel.
