45 amp charge controllers
Operating a solar panel system with a battery bank without a charge controller is outright dangerous. A quality model can significantly increase the battery's lifespan while also enhancing the system's overall security. We recommend using 45 amp solar charge controllers for smaller PV systems, such as those utilized in portable, RV, boat and similar applications.
As its name suggests, this important piece of equipment controls how the charging process works. A 45 amp solar charge controller usually has the following features:
A 45 amp charge controller won't be able to handle a large set of solar panels. You should use it if your project is medium-sized or small, like a few 200 W solar panels. There is a more accurate way to figure out if you need a 45 amp charge controller. To do this, you will need to divide the wattage of your panels by the voltage of your battery bank.
For example, if you have five 100 W solar panels and want to charge a 12 V battery, you'll need a charge controller that can handle 41.66 A (500 / 12 = 41.66). A 45 amp charge controller would be more than enough in this case.
When choosing a charge controller, one of the most important things to think about is whether to go with pulse-width modulation (PWM) or maximum power point tracking (MPPT).
It would be cheaper to use a 45 amp PWM solar charge controller. Also, because these controllers are not as complicated, they last longer. Between ten and twenty years is how long a PWM charge controller should last. The long life and low cost, however, come at the cost of efficiency. Using a 45 amp PWM solar charge controller would make it hard to customize the charging process and give you only 75–80% efficiency. Also, when the voltages of the panels and batteries don't match, this type of controller loses too much energy.
A 45 amp solar charge controller costs more if it uses MPPT technology. In exchange, you gain up to 99% charging efficiency and more control over the charging process. Depending on the manufacturer, the average lifespan of these controllers is between 10 and 15 years.
