Don’t let the exposed wires touch!ģ DIY Solar Power Projects You Can Build Now The extension cables are optional based on how far apart your solar panel and charge controller are.)įor the panel’s positive cable, connect the MC4 inline fuse, positive extension cable (if using), and then the MC4 adapter cable.įor the panel’s negative cable, connect the negative extension cable (if using) and then the MC4 adapter cable. I also bought MC4 solar extension cables. For my setup, I made my own by assembling a male and female MC4 connector. (These are basically a length of solar PV wire that has an MC4 connector at one end and is stripped at the other. MC4 solar adapter cables are needed to connect a solar panel to a charge controller To connect a solar panel to a charge controller, you need MC4 solar adapter cables. Most solar panel cables come with pre-attached MC4 connectors. Step 4: Connect the Solar Panel to the Charge Controller So I just kept it at the setting it was on. It defaults to sealed lead acid, which happens to be the type I’m using. Mine has a button which I can press to indicate battery type.

(I made one a little shorter to account for the fuse I’m going to attach to it.)Īt this point, your manual may tell you how to program the charge controller for your battery type, voltage, etc. Here’s how I did it:Ĭut two pieces of wire to the length you want and strip both ends. So I decided to save some money and make my own. I didn’t have pre-made battery cables lying around. Place another between the positive solar panel wire and the charge controller. Safety best practices, y’all! Place one fuse between the positive battery terminal and the charge controller. It’s recommended you fuse your system.Instead, connect both battery and solar panel to a solar charge controller. Don’t connect a solar panel directly to a battery.It’s important to understand the following: Here’s the wiring diagram showing how to connect a solar panel to a battery: Inline fuse holder with 20 amp blade fuse.MC4 solar extension cables (if necessary).Renogy Wanderer 30A solar charge controller.Otherwise, adjust the sizes of your components for the amount of current that’ll be flowing through your system. Note: I’ve listed the sizes I used and linked to either the exact materials I bought for my setup or materials that are compatible with it. Let’s get to it! Materials & Tools Materials (If that doesn’t get your blood pumping… I don’t know what will.)Īlright.

The manufacturers expect the Sunlight Direct system to be available for purchase in 2007.These instructions will show you, with step-by-step videos, one of the foundational skills of building DIY solar power systems: how to connect a solar panel to a battery.īy the end, you’ll be charging your 12 volt battery - or higher - with free solar energy. The best part is that Sunlight Direct is currently allowing people to beta-test this new product – so get on it peeps! (I would love to hear from anyone who tries this). One unit delivers 50,000 lumens, or roughly the equivalent amount of light needed to illuminate 1000 square feet.
Currently the light can only be sent about 30 feet or so due to loss of light as it travels through the lines. The system then filters out the heat-causing UV light, and pipes the remaining natural light into interior spaces via fiber optic lines. Sunlight Direct uses a parabolic mirror to collect sunlight. Unlike Parans, Sunlight Direct also incorporates Hybrid Solar Lighting (HSL) – the storage of solar energy to power fluorescent tubes in cases of low sunlight, such as on cloudy days, or at night. Like Parans, the Swedish sunlight transport system we covered a couple months back, Sunlight Direct is a fiber-optic sunlight transportation system designed so you can collect sunlight on a roof, and then bring it into the interior of a building to illuminate a dark room. Since sunlight is our most infinitely renewable resource, I am amazed that it has taken us so long to start developing hi-tech lighting and energy systems around it. Nothing in the realm of new technology gets me more excited than sunlight transportation.
