Questions about this item

Should I pick the 55-amp board or a lower-amp version for my WF-8955 converter?

The board is rated at 55 amps and 798 watts, matching the original WF-8955 and Parallax 7145 series specifications exactly; choose it when your converter requires that full current capacity.

What does the 55-amp rating actually deliver when the board is installed in my RV?

It supplies up to 55 amps of clean 12-volt DC power, enough to run lighting, sound systems and other appliances simultaneously while charging lead-acid or LiFePO4 batteries at 14.6 volts.

How does the 120-volt AC input limit what the board can output in practice?

The 120-volt AC input feeds the converter, which then caps DC output at 55 amps and 798 watts; the fixed-voltage mode can be adjusted between 13.0 and 16.5 volts within that power envelope.
