15 ft. Extension Cable

A:  Wire two 12v batteries In series to get 24v.  However, the charge controller for the solar panels I got was only 12v, not 24…

A:  The 600W MPPT kit is designed with the ability to charge either 12V or 24V batteries. No change to the solar configuration should be necessary.

A:  As far as we know, any connector labeled "MC4-comparable" or with similar verbiage should be compatible, although it is best to keep brands consistent if possible due to slight differences in the metal alloy composition that can degrade connections over a period of years.

A:  I have used cables from different manufacturers and have had no problem

A:  The Grape 15 foot Extension Cable MC4 connectors are universal and common to industry-wide solar products produced after about 2011. They are usually not used at the charge controller or conventional disconnect switches which have their own enclosure weather standards. A 6 inch MC4 to Bare Conversion Cable Pair is available to make the transition once out of the solar panel environment or cut a 15 ft Extension cable in half to make a longer conversion to bare pair. The other manufacturer should specify compatibility but they may not meet this standard if older.

A:  As far as I know these fit all types and brands of solar panels. I have not seen any that were different.

A:  You have "grape solar" panels ? ( I presume. ) I have and am using these extension cables and they are excellent.

A:  Yes you can have it shipped to the store nearest to you.

A:  Yes you will need 2 extensions, a controller, and a battery to store the power generated. it is bare wire hookup at the controller

A:  Two extension cables may not be necessary I have bought two of them didn't really have to.I have a 50 watt grape solar panel.It is mounted on a metal pole with a 35 amp 12volt battery and a 12-24 volt led Blazer spot light which is 18 watts connected to the controller box at the load output.So u will need a deep cycle battery for the solar panel.The size of battery depends on the watt output of your lights. I have harbour freight battery cost around $65 .Which is a deep cycle

A:  As noted below, for a cable run of less than ten feet you can simply cut one cable in half - you do need two cable runs, one positive and one negative. To run lights in your shed, assuming they run on AC power, you would need a panel, charge controller, deep cycle battery, and inverter. See our website for more details on basic solar.

A:  It depends on if you’re using it as just an extension or your final connection. The extension comes as only one cord with a male and female end. If you need a 15’ extension you’ll need 2 cords(+ and -) from the solar panel. If the one cord is long enough to be cut into 2 pieces and reach your controller then you’ll only need one. Coming from the panel the wires are + and - with male and female ends. Just be sure of your polarity when connecting to the controller and don’t install the single extension to the panel without it being cut first or it will short the panel. I hope this helped. I had the same problem finding information when I was building my system and can understand the frustration.

A:  You will need the extension cord you can cut it in half and use half for positive and the other half for negative into a charge controller witch than goes into a deep cycle battery 12 volt or a battery bank than you connect that to a power inverter than you can run whatever your inverter is powerful enough to run! Just one thing to remember or things get really expensive.... never run your deep cycle battery below 50% or you will kill your battery in a short amount of time....the great thing about solar is you can start small and add as you go
