Direct Replacement Board

The VEVOR RV Power Converter is a 55 Amp DC main board assembly built to replace WF-8955, WF-8955-AD and Parallax 7145 and 7155 series units. It accepts 120 V 60 Hz input and provides multi-stage smart charging for both lead-acid and LiFePO4 batteries.

Suits Matching Chassis

This board fits owners of the listed converter models who need a new main board. It does not suit installations that require a different input voltage or frequency, nor systems that demand an output current above 55 A.

55 Amp Output Rating

The unit delivers up to 55 A at selectable fixed voltages of 13.0 V, 14.6 V or 16.5 V, with a maximum power of 797.5 W. This single rating decides whether the board can support the intended battery bank and RV loads.

Questions about this item

Which model should I pick for a WF-8955 or Parallax 7145/7155 replacement?

The board is a direct replacement for WF-8955, WF-8955-AD and Parallax 7145/7155 series converters, supporting both lead-acid and LiFePO4 batteries.

What does the 55 Amp rating mean for my RV loads?

It supplies up to 55A at 14.5V for a peak of about 797.5W, enough to run lights, speakers and similar 12V loads while charging a 55–70Ah battery bank.

How does the 120V 60Hz input affect installation?

The converter requires a 120V 60Hz AC supply such as shore power or a generator; it does not operate from a 12V DC source.
