The “SOLAR PANEL ROUTER” forum section, hosted by basriacar ular, offers an excellent platform for sharing valuable insights and showcasing sample projects related to solar energy. Within the “Switched Power Supplies” category, you’ll find a dedicated space for inquiries and the opportunity to provide your suggestions. It’s a valuable resource for anyone keen on the solar energy topic.
Greetings, my friends. Allow me to clarify that I wouldn’t categorize myself as a complete novice in this field, but I also acknowledge that I’m not yet at an advanced level. Thus, I hesitate to label myself as a full-fledged programmer. However, I find myself deeply immersed in my solar energy project, and I’ve made significant strides. I’ve successfully achieved a 360-degree solar tracking capability, and I’ve completed the solar regulation circuit, which effectively boosts the voltage from a 6-volt panel to a level suitable for charging 12-volt batteries.
This is the Solar tracker’s scheme.
I’ve rearranged the schema. If you say, LM324 has 2 additional comparator opamps on the integrator. Click on.
Now, let’s delve into the second circuit, which centers around the use of solar panels in a cost-effective manner.
This circuit comprises three main components. The initial segment involves a voltage-boosting (dc-dc) switched power supply. I discovered a diagram online and modified it to align with my project’s objectives. It commences with the transformer. Subsequently, we eliminate the transformer and proceed to wind 28 turns of 0.40 mm diameter copper wire on both sides, equating the primary and secondary sides of the windings. You can employ 11 or ICE 90 for this purpose, and remember to incorporate a cooling mechanism.
The second component regulates the current generated in the first section by integrating the LM317 to attain the desired charging current at the output, while simultaneously ceasing the charging process when the battery reaches full capacity. By introducing a switch, you can even facilitate multiple charging outputs for diverse applications. Ensure that a cooling system is integrated with the LM317.
The third part encompasses a converter circuit that reveals the charging status through integration with the LM358. The second and third components constitute the original circuit for charging both 6 and 12-volt batteries, capable of handling a maximum of 1 Amp via the LM317. If you require a higher current capacity, you can opt for the LM338, which can accommodate over 3 Amps.
This circuit enables you to charge a variety of batteries, including 12-volt batteries, mobile phone batteries, 6-volt batteries, and even lithium batteries for remote-controlled devices. Moreover, it can be employed during camping, at sea, or in a caravan to provide illumination when needed. I am currently in the process of enhancing the circuit I designed by incorporating numerous additional features.
