30A pwm solar charge controller, model Steca PR3030. It is equipped with LCD display and is able to automatically recognize the battery voltage 12V or 24V. Windows 7 ethernet driver download. It withstands currents up to 30A and works with different types of batteries.
Will help you understand the difference between PWM or pulse width modulation, and MPPT or multi-point power tracking charge controllers and when to use each. Before go further, we want to go over a quick reminder of power calculations.
Solar panels are rated by their actual output when connected to a load. For instance, a generic 300 watt 24 volt nominal panel has an actual output of 36.1 volts VNP, and 8.3 amps JYMP. When you multiply them together, you get the rated Watts, 299.63 watts or round it up to the 300 Watts. You can see the specs on the solar modules back or in its datasheet.
A charge controller is an important component in a battery based system. They’re not used in straight grid type systems as they don’t have batteries to charge.
Their primary role is to manage charging the battery bank. It prevents it from overcharging and many of them control the current and voltage at which it charges. More on that in a moment, at night, the voltage of the battery bank is higher than that of the array that it’s connected to. Without a charge controller, the tendency would be for the voltage to flow out of the battery bank. A charge controller prevents that from happening, allowing the flow to only go one way into the batteries. Charge controllers are available with two different technologies PWM and MPPT.
You can’t often tell the difference between a PWM and MPPT charge controller just by looking at them. So how can you tell the difference between these two controllers. Generally, this information will be printed on the regulator’s label, or you’ll find it by checking the product manual. Win7 activator 50.
Beware, there are many unscrupulous sellers particularly on who simply print MPPT on a standard PWM controller. To prevent being fooled, it’s worth noting that MPPT is substantially more expensive to manufacture than PWM. So if the price seems too good to be true, it certainly is. Both PWM and MPPT ensure the batteries have been charged at the right voltage based on their state of charge. However, how they perform in a system are very different from each other. An MPPT charge controller is more expensive than PWM. Let’s go over why it’s often worth it to pay the extra money.
PWM charge controllers operate by making a connection directly from the solar array to the battery bank. During bulk charging when there is a continuous connection from the array to the battery bank, the array output voltage is pulled down to match the battery voltage. As the battery charges, the voltage of the battery rises.
So that the voltage output of the solar panel rises as well, using more of the solar power as it charges. MPPT charge controllers measure the VMP voltage of the panel and down convert the PVV voltage to the battery voltage. Because power in equals power out, when the voltage is dropped to match the battery bank, the current is raised. So you’re using more of the available power from the panel. Let’s see how this affects our system with a 100 watt 12 volt nominal panel with a 12 volt nominal battery bank. We’ll do the math assuming 100% efficiency which isn’t what you’ll see in real world, but it will really help illustrate the difference between PWM and MPPT quite clearly.
