Help please with a WFCO WF-8900

Hi Welcome to the forums.

How many watts of solar do you have? What controller? How many amp-hours of battery bank?

I agree solar is quite wonderful.

I have the WFCO type converter and added solar. I just brought the solar charge controller straight to the house batteries with fuses and an inline circuit breaker. That way the house batteries can be shut off and still maintained by the solor.

WFCO makes a transfer switch that just slides on the back of the WFCO converter and I use that for when I'm using the inverter. Normally goes to shore power input, but when it senses inverter power, it switches to that.

One important thing with my setup is that I put a sign next to the inverter remote switch to turn off the WFCO converter with the house-type circuit breaker, so it doesn't try to charge the batteries from the inverted battery power. Some people wire the 120v breaker of the WFCO converter directly to the shore power cable to avoid that loop of inefficient discharge when you forget and leave the converter on with the whole-coach inverter on also.

Multiple charging of batteries seems to work fine, just make sure they have max voltage cutoffs, which they do in every case I've looked at. You'll love the solar, and they are great for custom charging any battery configuration.

Yours may be different, but my Progressive Dynamics converter (charger) is located behind the rear wall of the basement and is plugged in to a regular 120V outlet with a short cord and plug.

UNplug it. OR, better yet expose the wire in the short cord and cut in a regular household light switch which can be mounted wherever convenient.

Hi
I had a 140v solar fitted to my KountryLite earlier this year. As far as I can understand the fitted charger can never fully charge the
2x125 a/h batteries, However the solar set-up has a voltage regulator that allows a charge greater than that achievable by the WFCO charger. I have never had any problems running both at the same time, but there again I don't use an inverter. My rig has a breaker dedicated to the charger alongside those for AC, TV etc.

Unplug. Open the panel and remove the front cover to expose the 120v wires. There is probably a breaker with two wires connected. The short wire with a wire nut is the connection to the WFCO converter. remove the wire nut, separate the wires and replace the wire nut on the short wire to the breaker to avoid any short circuit. This is a typical set up, yours could be different.

Post a pic of the wires if this does not seem easy.

Actually there is no need to disable the converter for the solar panels. However you do not want the inverter to power the converter as that will create a power loop that will discharge the batteries in a short time.

It would be a bit tedious but I think you could convert everything to your 230v 50 cycle if you are determined. Otherwise everything is designed for 120v 60 cycles. 12v battery and propane will usually run most systems without utility/inverter power.

Mine just plugged into the back of the power panel although I am sure it was on one of the circuit breakers. Every trailer puts it in a different location so I can't be sure about yours.
