Eaton PXG900 Pure Sine Wave Inverter/Charger

The Eaton PXG900 is a versatile power conversion solution that combines a 900 W pure sine wave inverter, a sophisticated battery charger, and an automatic transfer switch in a single enclosure. It converts DC power from batteries into clean, utility‑grade AC power to run sensitive electronics, appliances, and tools. When AC shore power is available, it automatically switches to charger mode to replenish the battery bank. This makes the PXG900 an essential component for mobile, marine, and off‑grid applications.

Key Features

• 900 W continuous output (1800 W surge for motor starts)

• Pure sine wave AC output (< 3% THD) – safe for all loads

• Integrated 3‑stage smart charger (bulk, absorption, float)

• Automatic 30 A transfer relay – seamless switch between inverter and grid

• Wide DC input range: 10–16 V (12 V nominal) or 20–32 V (24 V nominal)

• High efficiency: up to 88% in inverter mode, >85% in charge mode

Technical Specifications

Operation Modes

Inverter Mode: When no AC input is present, the PXG900 draws DC from the battery and produces clean AC power. Its pure sine wave output ensures that even sensitive medical equipment, laser printers, and variable‑speed motors operate without interference or overheating.

Charger Mode: When AC input is connected (grid or generator), the internal transfer switch routes AC to the loads and simultaneously activates the multi‑stage charger. The charger replenishes batteries quickly and safely, preventing overcharging.

Bypass Mode: The transfer switch can also pass AC directly through, allowing the unit to function as a simple battery charger while the inverter is offline.

Applications

• Recreational vehicles (RVs) and camper vans

• Boats and yachts

• Trucks and service vehicles

• Off‑grid cabins and remote monitoring stations

• Emergency backup power for small loads

Safety and Compliance

The PXG900 is designed to meet international safety standards including UL 458 (for marine/RV) and CSA C22.2. It is equipped with a ground fault circuit interrupter (GFCI) compatible output and isolated DC and AC sides for operator safety. The rugged aluminum housing dissipates heat efficiently and protects internal electronics from vibration and dust.

With its robust feature set and reliable performance, the Eaton PXG900 delivers peace of mind for anyone requiring dependable AC power on the move or off the grid.
