I have a trickle 7 amp that doesn't maintain my deep cell when in use running a gas camp fridge. Will this, and does it need a controller AND diodes?

It does need a controller. Will it charge/maintain your deep cell; mine is hooked in series with another 100 watt panel and it seems to work fine with my 4 group 31 batteries. It takes about two days for full charge after I run them down (which has only happened twice in two years).

It may help your system,you do need a controller also 2pannels are the better way to go.

Based on my experience with this, you will need two of them. Also note that they must have very direct sunlight, they don't work well on cloudy days either. All the controllers I am familiar with have the diodes built into them, or at least I thought they did. Mine is working just with the controller.

You can as long as the controller is rated at 45 watts. You will boil your battery dry if it isn't rated correctly. The three amp power supply is fine, it will not boil your battery dry. Battery tender has a help line and they are great to talk to.

http://www.susanminor.org/Rayeimages/pid/diagram.jpgas mark said.the crux here is that in addition to the PID controller, you also need a thermocouple of the correct type, and for most applications, a solid state relay such as the one shown. the PID output relay is only rated at 3Amps. chances are you are going to want more than that.

Yes you will need a charge controller, without it you will fry your battery. During hours of darkness it will not discharge you battery.

Hi -- I am an electrical engineer and I use this panel to keep the three full size 12V deep cycle batteries wired in parallel on my camper charged. It does a really good job and I do not use a charge controller. I mount the solar panel vertically facing south so that in the summer when the sun is high in the sky and the temps are warm it receives less solar input, but in the winter the sun angle is low and I get relatively more charge and any excess battery heating will be less of a concern. The panel seems to be very good quality and has held up fine outside in Park City UT for over 9 months. The current from the panel in full sun should nominally be 5w/12v = .42 amps, which may be a little high for trickle charging a small motorcycle battery. Check for your battery specs on line. By mounting the solar panel vertically it will generate less current in the summer and avoid overheating. You can also probably mask the panel with tape to reduce output if needed. Also, I don't think charge controllers are too expensive for this size panel so that is an option. Hope this helps. ---Dan in Park City UT

I just saw your question. I have done this. You can't run the controller and the pump off the same panel - When the controller turns on the pump, power drops and the controller shuts off, then on, off - etc. I used a seperate panel for the Elitech power. Make sure you have good thermal coupling to the fairly large sensor and it may not be waterproof. the relay will handle the pump on/off. You can set the gap in temp between turning on and off which means the pump doesn't cycle on and off alot.

If you use the reese towpower you'll need to run a number ten wire from the battery to the controller. Then back to your seven pin connector. You need the heavy wire to supply enough amps to activate the brakes.

depend on what you are hooking it up to. If using as a battery charger than yes you need a controller. If hooking up to grid tie inverter or D C heat element than no do not need a controller.

Check propane levels, keep purging line of air, several attempts may be needed. Check exhaust for debris (mud dauber nest clogging). The quick connect will not help you. My refrigerator works fine on propane but not on electric! (new camper!)

I just purchased one to power an air pump for a 1 acre ranch tank. In addition to the panel you will need a DC-ac inverter, charge controller, and a 12 volt marine (deep cycle) battery. The instructions that come with the controller (Renogy PWC30) are straight forward. I found you will also need to purchase the power cables that plug into the panel and go to the controller, as well as the cables that connect the controller to the battery. I had planned to run the pump 24/7, but the pump draws too much power for the panel to keep the batteries charged. Have decided to put a timer on the pump so that it will run only 5 hrs/ day. If not, may need to add another battery parallel. Hope this helps I just purchased one to power an air pump for a 1 acre ranch tank.

No, it needs the stripped wires. You can get pair of wires that have MC4 on one side to connect to panel and bare wire on the other to connect to the charge controller. Better to do this than cutting off the MC4 connectors.

Sorry but unless you have a serious Battery and Inverter setup. No. Dont get me wrong it is a good kit. I have two of them. but most Refrig and freezers need alot more amps than the kit provides. But it cold be used to keep a Battery charged and a bigger inverter could work. Check out the web folks are using these kits to make solar generators with good results.

no controller needed, can (like mine) be plugged directly into wall for tank circulation

I have successfully used it to keep my rv house batteries charged up during downtime. You should have no problems for your use. You will not need a controller as there will be no chance of overcharge with the small wattage.

No. No and No. No solar panel is designed for direct load to a cooler. Designed to trickle charge a battery for maintance only. 1.25 amp at 12 volts max output under perfect conditions.

i use it with two deepcycle batteries, i have a solar cell 68w connected to the batteries, it runs all the time with this setup in my camper

In a portion of my design (trailer wiring system), I have a 400 Watt DC to AC converter which connects to a AC wall outlet in my trailer. I have a trickle charger hooked up, so not many watts drawn. This has worked for me so far. The main wires going through relay end up having AC power through them. The actuator in the relay is controlled by magnet (and I still use 12 volt to control relay), so the magnet portion of relay doesn't make direct contact with AC power. Can't say for sure on 24 volt if it will work, since I still use 12 volts to actuate magnet in relay. I actually disected a relay to see how it worked before building my system. I hope this helps.
