Solar power booster circuit6/6/2023 Like conventional solar controllers, the charge regulation function of the boost controller also serves to regulate the charge from the solar panel to the battery and to protect the battery. and it is only for speeding up the charge process. Thinking that solar panels per watt are a bit costly, using a boost controller is much more economical instead of buying a lot of panels and a conventional solar controller.Ĭonventional solar controllers also have a Boost charge expression, but that refers to a voltage boost within a certain voltage range, not exceeding the PV voltage. When you have trouble charging large battery bank in marine and electric vehicles or even in a smaller solar system, you can use a boost mppt charge controller to boost the charge voltage and address this problemĪnother advantage of a boost controller is it can reduce investment. This process is automatic during the charging period. This process is commonly integrated with MPPT technology.īoost realised by lifting the current and voltage through specially designed circuit boards and capacitors. The job of the boost controller is to raise the voltage produced by the panel to charge a battery that is at a higher pressure than the panel. The solar controllers play a regulating role in this process. The solar charge controller works by distributing the high voltage current from the Panels to the lower voltage battery bank, for example, a 24V solar panel supplies 18V of electricity, which is moved to the 12V battery like a stream of water flowing down from a high place. This is especially designed for charging golf carts,electric vehicles, ebikes, RVs and marines, which usually don’t have much space for a large number of panels installed in these places. Here we can also use Solar Tracker Circuit so that sun light can fall on the panels all the day.Boost solar charge controller is a kind of charge controller that allows lower voltage panels to charge higher voltage battery banks with entire voltage and current boost function.īoost controllers allow you to use 12V, 24V,36V or 48V lower voltage solar panels to charge 36V, 48V,60V and 72V Battery banks. The details of the Booster Module is given in DC-DC Booster Details table This is where we will be suing the 5V Boost converter from which we directly power our phone. So we need something that could boost and regulate the voltage to 5V all the times irrespective of the radiation. This makes it clear that our panel will not provide 5.5V and 735mA all the time. The rating of a single panel is given in the solar panel details tableĪs we all know the output voltage and the current supplied from the panel directly depends on the solar radiation that falls on the panel. Hence, the final voltage and current rating of all the three modules will be 5.5V and 735mA (245+245+245). We will be using three of these panels which will be connected in parallel, as we all know connecting it in parallel will keep its voltage constant and sum up the current rating. Thus, we have selected the 5.5V 245mA solar panels. ![]() Since providing 1A and 5V using solar panel would make the project bulkier and expensive, we decided to design the system for more than 70% efficiency. In our case the load is the mobile and it requires about 5V and 1A to get charged in its maximum efficiency. ![]() In order to decide the voltage and the current rating of our panels we have to consider the voltage and current that would be consumed by the load. ![]() Monocrystalline, Polycrystalline and Amorphous are the three types of solar panels in which we will be using the Monocrystalline one, since it is commonly available and cheaper than the other two. To accomplish this we just need a solar panel, but there are lots of types and ratings in solar panel to select from. The Primary principle of this project is to convert solar energy into electrical energy.
