Multiple people in forums around here are reporting constant problems with WF-8955-AD converter and recommendation was instead go with Progressive Dynamics PD4655V, however there are quite a few forums that also report PD4655V does not charge fast off shore power and/or generator. Various wire charts on the internet will help explain distance, insulation rating, and distance for multiple voltages and current ratings.My RV has WFCO-8955PEC converter, it's for lead acid batteries, therefore I need to replace converter as my LiFePO4 batteries coming this week. Wire size should handle the current rating of the converter and the distance from the converter. Also, match wire size to the output of the converter. Make sure you have the proper fuse size to match the wire size gauge and insulation type of wire. While the WF-8725-AD converter will charge a 400-amp hour battery bank, consider upgrading the wire size and a converter size to a bigger charge output to maintain optimumĮfficiency when charging from a generator.ħ. In that case, it means out of a 100-amp hour battery, 80 percent is usable capacity, so charging at 25-amp hours, you will have just over three hours of charge time per battery. (this will be different for each battery manufacturer). Suppose we were using the full 80 percent capacity of the battery Example: 400-amp hour capacity battery bank with a WF-8725-AD unit. A smaller converter charger may take longer to charge. A larger converter charger is available for bigger battery banks. Make sure your battery bank capacity is manageable for the converter charger. This is part of the Auto Detection process to determine the correct battery profile for charging by the correct battery type.Ħ. If your battery is a lithium battery, make sure you discharge enough battery capacity to allow your WFCO converter to go into charge mode. If your battery feels hot to the touch, have your battery connections checked or have your batteries checked by a trained technician.ĥ. Using an old battery with a new one can damage the new battery if left in storage unattended for a period of time.Ĥ. Don’t mix battery types or old batteries with new batteries. Use recommended distilled water after a full charge.ģ. Don’t use electrolyte (battery acid) to top off your battery levels. With lead acid batteries, be sure to check water levels.Ģ. Any battery reading below 12 VDC while disconnected is a possible indication of battery trouble.ġ. Are you reading 13.6 VDC between the Positive battery lead and the Negative battery terminal? If not, the Reverse Polarity fuses may be blown at the converter or there is an OPEN fuse or battery disconnect switch in the Positive battery lead.Ĥ. Disconnect the Positive lead at the battery terminals and set aside.ģ. What is your battery condition? Does it have enough water? What is the age? Have you tested for shorted cells?ġ. Are all of the fuses on the DC panel OK? Are any red LED’s on?ĥ. Check breakers at the pedestal and in the power center for proper voltage.Ĥ. Locate and record the WFCO converter model number.ģ. The converter will not work without AC input.īefore you call the Power Pros check the following:ġ. Even in normal "Absorption Mode" (13.6 VDC range), your batteries are being charged, just at a slower rate.
