WFCO WF-8725-AD WF-8700-AD Series Power Center - 25 Amp, 105-130 VAC, 60 Hz, 430W , Black

Répond aux attentes.

I got this unit as a step up from Original so far so good

My primary product selection criteria was size of the cutout hole. I wanted an easy replacement. My popup camper is from 2002 and has a Centurion 3000 (20 amp version) that lithium batteries don't like (i.e. lead acid charging). The WF8725AD was an exact fit replacement, 25 amps and could auto detect lithium for a correct battery charge profile. I'm intending to charge a pair of Renogy 100 Ah LiFePO4 batteries that I've had for about a year.The WF8725AD install was easy. All the AC connections and chassis ground were inside the enclosure. Put the breakers in last because there is not a lot of room to work around them. The ground bus bar and neutral bus bar require short wires while the hot (black) wire has to be much longer to make it all the way down and around to the bottom of the breaker. It is easier to wire up the breakers while holding in your hand and then snap into position. Incoming shore power connects up to a similar large black wire using a wirenut.DC wiring is all outside the enclosure. It's color coded and connected to the camper load with wirenuts. I swiped the ground bus bar off the old Centurion to tie together all of the white DC ground wires along with chassis ground. AC breakers, DC fuses and a 3/4 inch romex connector were also reused from the Centurion. I had to buy a 1/2 inch romex connector and the wirenuts. The WF8725AD comes with a 30 amp DC fuse installed for self protection from a battery connected backwards. As long as you don't mix up AC and DC you can't go wrong.The WF8725AD uses indirect light from a color LED hidden deep inside to communicate charging status. It comes shipped from the factory in lead acid mode by default and the LED shines green. The LED slowly alternates between green and red to indicate bulk charging in the lead acid profile. When the auto detect function switches to lithium, the LED shines blue.After 24 hours of charging, the LED was still green and the batteries had a long way to go. I could tell my Renogy battery management system didn't like lead acid charging and was protecting itself by restricting current. That is when I called WFCO tech support and learned auto detect required a full charge cycle that included a 30 amp draw. I was instructed to put a 40 amp fuse in the battery (red wire) slot and another 40 amp fuse in the inline fuseholder by the battery box. With fully drained batteries it should detect lithium by the end of a charge cycle.Fortunately, my RV fridge has a DC setting that drains batteries overnight. Long story short - I tried 3 times to pull 30 amps during a charge and was unable to get more than 28 amps. My battery management system doesn't like lead acid charging and protects itself by restricting current. With a bluetooth app on my phone I can see exactly what each battery is drawing. I tried my hardest to make it work.Plan B is a jumper the WFCO tech support guy is sending by US mail. He also sent a 3 page .pdf with pictures that I've been reviewing while I wait for the jumper. The jumper defeats the auto detect feature and forces the WF8725AD into a lithium charging profile. The jumper install process involves removing the WF8725AD from cutout hole so you can loosen a connector that secures DC wires coming out of the back. Those wires need some slack to accommodate a circuit board that has to be moved out of the way. The jumper fits on a row of 6 header pins on another circuit board now accessible. It took some wiggle, pin straightening and circuit board flex to get the jumper in place, but the blue LED light was so satisfying.Sorry if I got carried away with this product review. I wrote it mostly for myself so I could keep track of what I did on the installation. My local RV shop wanted $1,100 for the WF8725AD and install labor, so I took my time removing and documenting every wire. Hopefully, it will help someone make an informed decision. I gave 4 stars because auto detect didn't work for me, but I was impressed with WFCO tech support and ended up with a custom lithium setup. Hint: it would have been much easier to put the jumper on before the install, but I'm smarter now and hopefully you are too.

J'ai remplacé mon convertisseur d'origine de même marque car le mien était défectueux et celui-ci est amélioré car il s'ajuste en fonction du type de batterie utilisée 👍
