Types of Solar Charge Controllers

There are many different types of solar charge controllers available on the market. These devices are used to regulate the voltage between the solar panels and the batteries. Many of the newer models allow you to control the load and even measure the temperature outside the panel. Some of these devices can also be used for monitoring the health of the battery.

Depending on the type of system you're building, you'll want to select the right controller for your needs. The most basic ones will cost less than $500. More expensive systems can cost more than $1500. You'll want to find a model that can handle the current that you need.

A good solar charge controller is a vital component of any photovoltaic (PV) system. They help you to control the flow of power from the solar panels to the batteries, protecting your investment. Often, they have a corresponding low voltage disconnect point, which will prevent loads from being connected when the battery becomes low.

PWM Solar Charge Controllers are the standard type of charge controller. This is a low cost option for small 12V systems. When you have more than one solar panel, you'll want to consider a series controller. With a series controller, you can connect multiple panels in series. This will reduce the amount of power that the panels have to produce, and make them work at the same power level as the batteries.

MPPT Solar Charge Controllers, on the other hand, are more complex and more expensive. While they do a similar trick as a PWM controller, the name of the game here is the technology used to adjust the output of the PV array to maximize energy production.

The most important function of a solar charge controller is the regulation of the voltage between the panels and the batteries. This is especially true in larger solar panel systems, where the voltages aren't typically aligned. In order to keep your battery in top shape, you'll need to monitor your battery's status and adjust the charging voltage accordingly.

PWM solar charge controllers are a good choice if you're on a budget, or simply don't have the room to install a complicated charger. However, if you're planning on installing a large solar panel array, you may want to consider the more expensive MPPT type.

PWM is also the best choice if you're looking to save on costs. While PWM isn't as sophisticated as MPPT, the technology is still quite impressive. To get the most out of your PWM solar charge controller, make sure to match the output voltage of the array to the nominal system voltage. Getting this right will help ensure that the best charging technology is employed, resulting in faster and more efficient charging.
