High-capacity 100-amp deck mount RV converter/charger with patented Auto Detect technology. Separate 3-stage lead-acid and 2-stage lithium-ion charging profiles. 1,710W input capacity. 84% efficiency at full load. Clean DC output without battery filtering. Quiet fan-only operation. UL & cUL / FCC Class B. 2-year warranty.
A deck mount converter/charger is a standalone unit that mounts directly to a surface (wall, floor, or cabinet) rather than integrating into a power center panel with built-in breakers and DC fuse blocks. It is the converter/charger component only — no breaker panel or DC distribution is included. At 100 amps, the WF-68100-AD is suited to Class A and Class C motorhomes, large fifth wheels, and high-demand RV electrical systems where maximum converter capacity is required.
The WF-68100-AD Converter/Charger includes the exclusive, patented Auto Detect technology. This microprocessor-driven technology will recognize lithium-ion and lead-acid battery chemistries and automatically adjust the charging profile to match the battery type.
No more buttons. No more switches. An accurately charged battery gives RV owners peace of mind. Eliminating the risk of over- and under-charging, the WF-68100-AD will maximize your battery life with multi-stage charging and current monitoring in both lead-acid and lithium-ion profiles.
The WF-68100-AD has optimized charging for battery chemistry built in:
The WFCO WF-68100-AD is the highest-capacity deck mount converter/charger in this lineup — 100 amps of steady DC output with 1,710W of input capacity, engineered for Class A motorhomes, large diesel pushers, and high-demand fifth wheels where lower-amp converters can't keep pace with the electrical load. At 84% efficiency under full load with a unity power factor of 0.99, it delivers exceptional performance without wasting power as heat.
Unlike the smaller units in the series, the WF-68100-AD provides distinct charging profiles for each battery type — three-stage for lead-acid (13.2–14.4VDC) and two-stage for lithium-ion (13.6–14.6VDC) — with separate bulk voltages (14.4VDC for LA, 14.6VDC for Li) to precisely match each chemistry's requirements. Fan-only-when-needed quiet operation, full protection suite, UL & cUL listed, FCC Class B.
