Make your own Photovoltaic Off-Grid System


ever since I got myself garage half a year ago there has been one problem even though it looks like electricity should be available in reality it is not hooked up to the power grids and thus I’m dependent on sunlight as the only light source so in this video let’s change this by reconstructing the wiring and adding a photovoltaic off-grid system to my brush so that I can see what I’m doing even when the Sun went down let’s get started as with every electrical room while ring we started off with a layout time in which we decided on a position for the LED strips junction boxes sockets of the light switch and so on afterwards we marked an approximate position for the switch and the judgment boxes onto the wall and measured the distances between all of them to come up with an estimated length of the different wire kinds and installation conduits so we went on a trip to the nearest home-improvement store to buy one switch three sockets pipe clips one big junction box for small junction boxes and 16 installation conduits and three kinds of wire why three kinds you may ask well we use so-called NIMH wire to connect all the sockets and parallel and hook them up to the output of an inverter that on its input side directly connects to load outputs of the solar charge controller we use the thinner Giusti wire to create a serious connection consisting of the light switch and an additional read switch in order to trigger relay when the switch is turned on and the garage doors opens because read switch will the magnet is mounted to its and it read switch closes is contact when a magnet comes near it when triggering the relay then connects d12 to power from load outputs through the LED strips which we all connected in parallel by utilizing the last wire kinds common four square millimeter speaker cable and while we had the subject of the wiring diagram the 100 watt solar panel connected directly to the PV input of the blue solar charge controller while the big and rather heavy led as a battery with a voltage of 12 volts a capacity of 100 amp hours and deep cycle capability connected to the value input of the charge controller and now with the diagram out of the way it was time to remove the old switch lights junction boxes wires wire clips sockets and so on basically everything else then we mounted the switch sockets and the junction box to the right wall of the garage with screws secure pipe clips with a distance of 10 centimeters from each electrical components and added more clips in between those components with a maximum distance of 60 centimeters to born a novel afterwards we measure the length between the first and last clip for one pipe length added 8 centimeters mark this length onto a pipe used a hand saw to cut it to size and clicked it into place and just in case you need a greater length than 3 meters which is the normal length of such a pipe you can always easily connect two of them together and if you ask yourself why we use two installation conduits parallel to each other and set up this one then you should know that AC and DC cables should always be laid separators not only through the pipes but also when it comes to the wiring inside the junction boxes but getting back to topic after finishing the installation on the right wall of the garage we added the junction box for the LEDs at the back of the garage and mounted most of insulation conduits there as well next we drilled the holes for the LED strip clips and secure them in place with screws but before attaching the LEDs though we marked a point in the center of the first LED clips row and will the hole they are all the way through up to the roof of the garage after enlarging the hole from the other sides I hammered a pipe through its and open up out of pitch which I applied all around the pipe to seal off the newly-created hole to mount the solar panel we created a fitting square shape of the panel out of the bitumen directed the extension solar wires through the pipe hooked them up to the panel through mc4 connectors and press the panel into the bitumen square to further protect the initially created hole from water though we added an additional layer of bitumen all around the edges of the solar panel inside the garage we then shortened the pipe and continued by creating fitting lengths of the warm white and cold white 5630 LED strip to mount it to the ceiling I utilized the piece of wire insulation between the LED strip and clip to apply enough pressure to the LED strip so that it stays in place but I only use this additional piece of insulation for the first and last clip not for the other clips in between them then I saw a lot thinner 1.5 square millimeter wire pieces to the four square millimeter wire in order to easily hook them up to the beginning of each LED strip without ripping off t cover pads of these strips next we mounted the remaining DC and AC junction box as well as the solar charge controller to the back of the garage and utilized instant glue to attach the reed switch to the garage door mounting interfering magnets to the garage door and by hooking up two wires of the Giusti cable to the reed switch and directing the cable into the junction box we started off with the actual wiring that means we pushed all the required cables through the pipes and partly into the junction boxes cut them to size and wired up the switch and both sockets afterwards we connected all the LEDs in parallel with voirbo terminals added a mounting for the inverter to the wall which was then attached with zip ties and continued by adding the load wires to the charge controller which we then connected to the inverter and the relay circuits inside the DC junction box and of course it is always a good idea to solve the relay along with PCB terminals to purport before hands to make the wiring easier later on now to perform the first test of the system we connected for scrambling inner wires to the battery terminals of the charge controller which directly connects to the battery terminals and attach the wires of the solar panel to the PB terminals and by flicking the light switch the LEDs turned on without a problem and by adding a Bluetooth module to the charge controller we can even use nap to see whether the battery gets charged through the solar panel or discharged through the LEDs and after finishing the AC wiring and closing all the junction boxes this solar off-grid system was completes and works like a charm I hope you liked this project and learned a thing or two about electrical wiring as always don’t forget to Like share and subscribe stay creative and I will see you next time
