Solar charger question

Hi Everyone,

I'm am relatively new to RVs and even newer to Class A's. We just purchased a 2007 Allegro 28DA after one summer in a Class C and I'm finding a few things I don't understand.

The coach has a solar charging system installed on the roof. Don't know what brand or type. The control panel shows 13 - 14 volts charging almost all the time, and says the battery (2 x 6 volt) is 100% charged.

With nothing turned on in the coach and not plugged into shore power, the batteries go down in a couple of days ? The other problem is the solar system says they are good and 100% charged, but the system inside the coach says they are low. Based on the lights, the inside monitor is correct... Not sure what to check ?

There is also a fuzz missing on the front of the solar control panel marked "Batt" ? Here is a picture of the control panel:

Hope someone can help...

Get a reading off the batts with a multimeter. That reading will be a base to indicate which meter in the coach is correct.

I suspect the solar charge controller may be hooked to a small rinky dinky solar panel that is doing nothing. If you take out the remaining fuse, I'd think the results would be.......Nothing.

Ed, the solar panel on the roof is approx. 4' x 4', maybe a little bigger. I have not checked the voltage with a meter, will have to do that.

Logic says that there needs to be a fuse in the fuse holder in order for it to work correctly. You should call Speciality Concepts Inc and talk to them.

X2 on the fuse. It will show 12 volts + , but the question is how many amps. It will vary depending on the capability of the panel and the amount of sun.

That 4X4 panel just MAY keep a full batt full, but would do very little in the charging department. It's probably in the 40 watt range so a couple of amps on a good day, once working properly.

4x4 is a lot of solar panel - much more than most rvs with solar. 16 sq. ft of panel space. If decent quality it ought to be in the 150 watt range (10 watts per sq ft is typical). That kind of wattage could provide a 10 amp charge rate, which is not trivial.

I suspect the 14.0v shown may be the power direct from the panel and not necessarily the current state of charge.

The panel can be delivering plenty of charge but that doesn't mean the batteries are accepting and storing it. In fact, the symptoms you describe suggest poor batteries or a lot of background (phantom) loads which can quickly drain even a good battery. For example, a steady 2 amp drain over 48 hours is 96 amp-hours or about 45% of what your 2 x 6v batteries could store when they were new. I would expect to see voltage in the 11.9 range at that charge level, and that is considerably dimmer than the 13.6v you are accustomed to on shore power.

Go here type_Document_Title_here and down load the manual and trouble shooting manual for your Mark 15 controller. It appears you are missing the battery fuse, without it the controller will not charge the batteries.
