Review on WFCO WF9855 WF 9855 Mount Converter by Doug Hinrichsen

The WFCO converter exceeded my expectations. The output voltage under different load conditions has been carefully measured. Once the RV batteries were fully charged, the inverter automatically switched to trickle charging to keep the batteries static. The device was easy to install and very quiet. Every time the device is turned on, the fan is turned on for a moment regardless of the load to check the fan operation. My old converter tended to drain the batteries due to overcharging during unoccupied periods. With the new converter this is no longer a problem.
