I am in need of an outside power source for my pig hut. I do not have an outside power source. I will need to be able to plug a small heater or fan (depending on weather) into the unit. Can I use this for this purpose? If not can you please help me find w

Asked by: MMKA
This kit is not recommended for a heater. Solar production is lowest in the winter, and heaters (even small ones) require very large amounts of power. To find a good system size based on your kWh requirements, you can use the National Renewable Energy Laboratory's PV Watts Calculator found at pvwatts.nrel.gov. For the calculator, the 50 watt kit is 0.05 kW DC.

will this be enough to power a laptop, a stereo turntable and one lamp?

Asked by: chrbc7
It is difficult to estimate without knowing the wattage of each device and the number of hours per day you want to run them. You can expect to produce around 150 watt-hours per day with a single 50W solar panel. Feel free to get in touch with Grape Solar for help with calculating your watt-hour load, and optimum battery or system sizing.

I have a 12 volt 50 AH battery powering a security camera. Will this kit keep the battery charged?

Asked by: Bryanste
We would need to know your location and the wattage draw of the camera to answer this definitively. A 50 watt panel produces approx. 12.5 amp-hours per day (150 watt-hours), assuming ideal panel placement (more in summer, less in winter).

Is the controller weather proof?  Wires too ?  I will us this on my trailer and it will be out in the weather

Asked by: Dan Watkins
The cables and connectors are waterproof, the controller is not. It must be protected from the weather by a structure or weatherized container (NEMA 3R or better).

how do I connect an outlet just to plug in a 56volt battery charger to charge the battery I use for my garden tools??

Asked by: tommy V
You can't do that with this kit, you would need a kit with an inverter such as the 300, or 400 watt kits. You could also use this kit, and purchase a small pure sine wave inverter separately. You must also have a separate deep cycle battery - you charge the battery with the solar kit, and use the inverter to run the battery charger. This is not an efficient use of solar, and is not generally recommended, since you are going from DC to AC to DC again.

Is this kit strong enough to charge a 12v marine battery that is hooked up to an electric fence energizer. It would be covered out of the weather. I am looking to hook both solar panel and fence energizer to the 12v marine battery.

Asked by: mtgal
Yes, this kit is designed to charge 12 volt deep cycle batteries. Just make sure the controller is covered and protected from the weather, preferably in a NEMA-4 or better rated container.

I have a travel trailer that is pre wired for ZAMP solar panel a plug on the outside from what I can tell the wires are there but previous owner took the panel and controller will this work wit what I have?

Asked by: Jt Fudd
Great question. ZAMP uses a proprietary port/ connector system. Our solar panels use the industry-standard MC4 port/connector system. In order to connect the Grape Solar panel to the pre-wired Zamp port, you would need to modify an adapter.

50w cant possably put out 40 amps.. is it a misprit..or more like 4 amps ..nothing states any amps on any of the panals..i only need the panal. My controller is good up to 10 amps on a ney artic fox camper.my current panal is 20w an mabe 1.1amps ..

Asked by: 1bakercustom
This was a typo and has been corrected, thank you. The estimated output amperage ranges from 3.75 amps (one 50-W panel) to 11.25 amps (three 50W panels).
