Since there is two 10' lines (1+ &amp; 1-) going from the solar panels to the 12v controller, does that mean the controller is mounted on the roof too?

The charge controller is not waterproof so it should be interior. If you need longer cable between panel and charge controller, please place an order and call our office for the option of upgrade. Make sure mention your order ID so we can easily pull out your information.

I don't know, as mine crapped-out (just like a sick dog with Diarrhea in the dog park ) after the first day of use. But yes, the solar panel is on the top.

The solar controller and generated can be connected to the same battery in parallel and not have any problems.I would only see an isolator or disconnect switch necessary if you wanted to remove your batteries and switch them with a different set or configuration.That way you can disconnect your panels while managing your batteries. This is good for preventing your charge controller from getting damaged.Let us know if you need further assistance.Regards,AW

The positive and negative wires from the solar connect to the appropriate connection in, in the contrôlée. The positive out goes to the battery + and the negative out goes to the battery negative post. The controller is not grounded, no ground terminal.

Yes I have it in line with the 12 volt solar controller also purchased from amazon that's all I used it for works excellent

That is only part of the reason to use a solar power controller. It also controls the charging voltage corresponding to the state of charge in the battery, just like a smart battery charger.

No. This is panel only. I bought a 20amp regulator/controller from ramsond fairly cheap. Both work very well.

Yes. Volts are like "pushing power". Your 18 volts can push into your 12-volt battery. The question is, how does your battery stop the pushing once it's full? That's what the charge controller is for -- once your battery is full, the controller steps off or cuts off the voltage. Just make sure that you pick a controller that can handle the amps -- a controller rated at 10 amps would be a poor choice for a solar panel or panels over 110-120 watts. (To figure out how many amps you need, divide the watts by roughly 11 and give yourself a safety margin.) These smaller controllers are great for a single 50-watt panel. Yes.

No I would use both solar panels Parallel to each other and use only one controller. Make no sense to use two separate controllers. Un less the panels produce more then 30A each.

There is just a solar panel. And you would have to mount it to some post and may need some additional wire to connect it to solar charge controller.

Yes, it's for the 12v system. I used it with the Bluesky 25amp controller. Grape Solar tech support is excellent, they helped me to pick everything for the local RV shop to install

I've not had to hook it up in any particular order. My issue was that the connecting plus from the solar panel didn't fit the controller and had to be cut off and shoved in then tightened down. Also the flashing red lights are confusing. Can fee hard to differentiate between when it's hired up incorrectly and when it's notchanging the batteries due to insufficient sunlight. Would have been better to have had more colors for the warning lights than just red.

I used no.10 (9 ft) from panels to controller then no. 6 (8 ft) to the batteries.

No, it's a all in one device. Just needs to be mounted on the roof. No wiring required.

If installed correctly, yes... You would need to install quick disconnect couplings some where in the PVC lines running to the solar panels in order to unhook the solar panels from the PVC lines... If properly installed the roof brackets would have to remain on the roof, removing them might cause leaks in the roof... The screws holding them need to be sealed with a roofing silicone which may cause a leak if removed... If properly installed and drained for the summer months I do not see any reason to remove it from the roof... Hope this helps...

I have one installed in a metal box on the roof. It has already been down to -10 F and probably to 100 F. That said, you may want to look at a MPPT charger. It seems you never get enough power out of a solar panel and the MPPT charger can get up to 30% more power to the battery / load. Its because a solar panel is a constant current device. The current is a function of how much light is hitting the solar panel and with a PWM charger you are pulling the voltage down to the battery voltage instead of allowing it to work at about 19 volts, which is the maximum power point for most 12 volt panes.

Yes, for our project it included all [Solar panel, Fan Unit, screws and cable] the parts, but that said, our high peak wall vent was just under the roof peak facing, correctly, to the south and we snaked the 10'+ Solar panel, mounted high up on the roof almost to the peak vents, and wired/plugged it in thru the roof top vent down to the attic and over to the Fan/vent. [If your fan and panel are NOT that close you may need to buy/extend the two wire/cable. Plus with full sun we can hear the fan running in the bedroom below, but is NOT very loud and only in the day time. Also we had to use cut down, scrap 2" X 4" boards to "pad" down the 3" bigger square vent grill to make it fit the fan unit and be air tight, which of course did NOT show from the outside and we made the vent removable with 4 screws and caulking for outside access to avoid the attic insulation and long crawl space to get to that end.] During a new roof install the roofer noted this fan would have worked better if we had the correct eave vents vs. the side wall vents on each end wall for roof longevity AND for removing excess heat. [The small solar panel was easily removed/unplugged to put on the new roof.] The 70 deg. Temp. cut off Sensor stops the unit from working in the colder months which was an extra $16... http://www.amazon.com/gp/product/B0002YVUOO/ref=oh_details_o03_s00_i01?ie=UTF8&psc=1 AS ALL WAYS - SAFETY FIRST WITH LADDERS AND ROOF WALKING !!! [We used a contractor which added about another $250 due to the vent carpentry work and our inability to run the roof/ladders.] Bigger question: NOT sure how long the payback will be, but did reduce the temp. some on the upper floor bedrooms where all the house heat goes with our poor/undersized central HVAC system. This was purchased to be an HVAC power saving device.
