Compatibility notes

It is listed as compatible with lithium and lead-acid batteries, including AGM and gel, and several sellers note a battery-mode switch or lithium charging mode. The replacement/cross-reference list shown includes WFCO WF-8945ANP, WFCO WF-8740P, Parallax 7345, Parallax 8345, Parallax 7145, Powermax PPC-32, and Powermax PPC-45, but not all are direct replacements and modifications may be required.

Replacement use

This unit is commonly described as a compact all-in-one replacement for older RV power centers, especially where you want both the breaker/fuse panel and converter in one box. If you are checking fitment, the rear cutout listed is 10-3/4" long by 7-1/4" tall, which is the most important physical measurement to verify before ordering
