zixixvan WF-8955AN 55A RV Power Converter — Lead‑Acid & Lithium Auto‑Detect, Quiet Fan Replacement for WF-8955/Parallax 7155/7145

This upgraded WF-8955AN converter provides reliable DC charging for RV house batteries, combining battery-type recognition, quiet cooling, and built-in protections. Designed for easy replacement of common WF-8955 and Parallax 7155 and 7145 power centers, it delivers a steady 55 A output while minimizing fan noise and protecting your batteries from improper charging.

How does this converter handle different battery chemistries?

The unit includes selectable lead-acid and lithium modes and supports automatic detection to match charging behavior to battery chemistry. A red mode switch selects lithium when on, and lead-acid when flipped to the opposite position, giving you manual control plus compatibility flexibility.

• Red slide switch for lithium or lead-acid operation.
• Automatic detection supports proper charging profile alignment.
• Prevents overcharging by applying chemistry-appropriate voltage and regulation.

Will the cooling fan make my RV noisy?

The WF-8955AN uses an on-demand cooling fan that stays off until internal temperature or load demands extra cooling, so typical operation is quiet. Only when the converter is under significant load or running warmer will the fan activate, reducing unnecessary noise and wear.

• Fan remains off during light loads for silent operation.
• Activates automatically only when cooling is required.
• Thermal and current thresholds protect the electronics and battery.

Is this an easy replacement for WF-8955 or Parallax units?

The WF-8955AN was engineered as a direct-fit replacement for WF-8955 and Parallax 7155/7145 power centers, matching output and installation points. Installers will find familiar mounting and electrical characteristics, simplifying swaps in many RV power closets.

• 55 A DC output matches common replacement needs.
• Compatible electrical input: 105–130 VAC, 60 Hz.
• Designed to fit existing WF-8955 and Parallax 7155/7145 locations in many RVs.

What protections and performance can I expect?

This converter includes safeguards for over-current, over-temperature, incorrect voltage, and reverse polarity to protect both the unit and connected batteries. With regulated 55 A output, it charges efficiently while avoiding over- and under-charging scenarios when used in the correct battery mode.

• Over-current and over-temperature shutdown features.
• Voltage regulation to maintain stable charging under variable loads.
• Reverse polarity protection to prevent damage from miswiring.

Who is this for? RV owners, fleet technicians, and marine installers who need a quiet, reliable 55-amp converter that supports both lead-acid and lithium battery systems will benefit from the zixixvan WF-8955AN. It’s especially suited to those replacing WF-8955 or Parallax 7145/7155 power centers or anyone seeking a compact converter with automatic detection, on-demand cooling, and built-in safety features. Backed by after-sale support, it’s a practical choice for keeping house batteries charged efficiently during travel or stationary use.
