RE: Xanrex Inverter/Charger Over Charging

That is not what your invoice lists. Also Prowatt remote on your invoice does not seem to be compatible with Freedom HFS which should use #808-9017 remote.

RE: Xanrex Inverter/Charger Over Charging

I think the first thing to do is to establish what do you have. Freedom Xi is an INVERTER with built-in transfer switch, Freedom HFS is INVERTER/CHARGER. They look very similar: Freedom HFS-inverter/charger Freedom Xi-inverter with built-in transfer switch

RE: Car Stereo Replacement in RV Problems

My guess is the original radio was low power two channel type and had built in fader control. Since your outside radio has only two speakers it does not need fader control. So in order to hear sound from both speakers in any position of fader control they connected output for front and rear speakers together on both left and right channels. This is commonly done and is OK. Most radios today are high power BTL type with four separate amplifier outputs and built in fader control. None of the speaker output wire connections are grounded and MUST NOT be grounded. Each speaker has to have separate twin line. There are just too many different scenarios and all depends on a particular model off the radio you have. The instructions that come with a radio tells you what you have and how to wire it. Your speakers might be shorted but also may not be-depends on the meter you used. Good luck

RE: 22.5 Wheel size ?????

As said before, there are two kinds of mounting: hub piloted that use big hole for centering and use nuts with flat washers and stud piloted that use conical nuts for centering. Chances are the wheel you are trying to match is made by Accuride and will have part number stamped on the inside of the wheel together with max load and max pressure data.

RE: It's So Easy To Make Primitive LED Diagnostics

The pictured item could be LED type but it could also be the old style neon indicator. I was recently testing some leds and got a surprise. The meter I use most of the time indicated bad led while I knew it was good. My Fluke 85 had no trouble determining the led was good. It turns out the meter that had trouble only puts out 2.5V in semiconductor test position while Fluke puts out 3.77V in the same position. 2.5V was not enough to turn white led on.

RE: RV Inverter Repair

I recently repaired my Xantrex PROwatt 600 SW. After about three years of flawless operation it just quit. No AC output. Customary eyeball inspection failed to detect anything unusual. No smoke, nothing burned. Further testing with instruments found both IRF 1404 mosfets shorted and 5.1 ohm resistors feeding gates open. Total cost: 2x $1.70 + 2x $0.13 $3.66. The unit is well built-good quality.

RE: SCR's Please Educate Me :)

SCR is a semiconductor device used to turn the current on and off. The SCR conduct in one direction when triggered, Triac in both directions. To turn it off the current has to be reversed or turned off by other means. They come in small sizes up to hockey puck size for controlling high power equipment. They were popular in equipment built in seventies and eighties.

RE: 8.1 Workhorse exhaust bolt broken

I removed several broken studs by drilling(carefully) 1/8" hole and spraying WD 40 thru the hole. Let sit overnight and use easy-out to remove broken stud.

RE: Canadian Snowbird needs TV Satelite Help!

Make sure everything works before you leave. Don't ever call your provider from outside the country If you have to call for any reason, do it from your home address. Use it regularly or otherwise your receiver may get "out of sync" requiring phone call to your provider. Good luck

RE: Solar panel shading

Good catch time2roll. I realized that as soon as I posted it.

RE: Solar panel shading

CA Traveler: The math in your example is incorrect: Theoretical output of panels in series hook-up with no shade 8A*(30V+30V+30V)=720W Theoretical output of panels in parallel hook-up with no shade: (8A+8A+8A)*30V=720W Output from panels in series with one panel in shade: 8A*30V+8A*30V-8A*1.8V=465.6W Output from panels in parallel with one panel in shade: 8A*30V+8A*30V+0A*0V=480W Your analysis would work if there were 9 resistors in series. Instead there are 9 CURRENT sources in series. Not the same thing. Assuming partial shade of one panel,the output would be: Panels in series-anyone's guess Panels in parallel-at least 480 watts

RE: Solar panel shading

That is exactly what I was doing when I did initial testing of my panels. How do you explain total loss of output when only one cell shaded on the panel that had 3 by-pass diodes. Seems that things are not that simple when it comes to solar panels.

RE: Solar panel shading

Solar panel is a CURRENT source. How much power(watts) does it produce when short circuit amps are say 8A and voltage is 0V?

RE: Solar panel shading

Typical 12V nominal solar panel has 36 cells connected in series. Before I installed my solar system in 2006 I did testing of effect of shadowing on the output from the panel. Complete shading of as little as one cell would completely kill the output from the whole panel. Connecting panels in series makes situation even worse when any of the cells in chain are in shadow. That is why I prefer parallel connection of panels.

RE: Another reason I hate my F150

Your guys don't know how good you have it. You could own 2014 VW TDI and change transmission fluid every 60000 km with expensive synthetic fluid and do it from the bottom with a car perfectly level until fluid start coming out thru overflow tube. No dipstick either.

RE: operating temperature

Your cooling system thermostat does not open until coolant reaches 192-196 Deg F. Its OK. Boiling temperature of WATER is 212 Deg F and pressurized cooling system increases this temperature even more.

RE: Nitrogen Tire Top Off Kit

There is no question nitrogen in tires is better than plain air but I would not bother with nitrogen unless you can get it for free like in Costco. Next best thing is to install coalescing filter on you compressor and manually drain water every once in a while. Coalescing filter

RE: How many amps does this stereo amp use per hour??

If your solar system can charge with 3A, you will be fine.

RE: How many amps does this stereo amp use per hour??

The reason car stereo speakers are 4 Ohm impedance is to increase power. Maximum power delivered to speakers is V*V/R(Z really). You either increase output voltage or lower the speaker impedance for highest power. All that is beside the point. There is only so much volume any human an tolerate. OP speakers would have to be unusually inefficient to require more power to achieve desired volume. That is why I suggest measuring actual DC current to get the picture. I have Bose home audio system in my motorhome powered by an inverter and its contribution to total current at 12V nominal is less than 2A at any volume. Measured continuously by Blue-Sky IPN-PRO with shunt.
