What’s a Solar Charge Controller

A solar cost controller manages the power going into the battery bank from the solar array. It ensures that the deep cycle batteries aren’t overcharged in the course of the day, and that the power doesn’t run backwards to the solar panels overnight and drain the batteries. Some cost controllers are available with additional capabilities, like lighting and load control, but managing the power is its major job.

A solar cost controller is available in two completely different applied sciences, PWM and MPPT. How they perform in a system may be very completely different from each other. An MPPT cost controller is more expensive than a PWM cost controller, and it is usually value it to pay the additional money.

PWM SOLAR CHARGE CONTROLLER

A PWM solar cost controller stands for “Pulse Width Modulation”. These operate by making a connection directly from the solar array to the battery bank. Throughout bulk charging, when there is a continuous connection from the array to the battery bank, the array output voltage is ‘pulled down’ to the battery voltage. Because the battery expenses, the voltage of the battery rises, so the voltage output of the solar panel rises as well, using more of the solar energy as it charges. In consequence, it’s essential to make positive you match the nominal voltage of the solar array with the voltage of the battery bank. *Note that once we consult with a 12V solar panel, that means a panel that’s designed to work with a 12V battery. The precise voltage of a 12V solar panel, when related to a load, is near 18 Vmp (Volts at most energy). This is because a higher voltage supply is required to cost a battery. If the battery and solar panel both started on the similar voltage, the battery wouldn’t charge.

A 12V solar panel can cost a 12V battery. A 24V solar panel or solar array (two 12V panels wired in series) is required for a 24V battery bank, and 48V array is needed for 48V bank. In case you try to cost a 12V battery with a 24V solar panel, you will be throwing over half of the panel’s power away. In case you attempt to cost a 24V battery bank with a 12V solar panel, you will be throwing away a hundred% of the panel’s potential, and may actually drain the battery as well.

An MPPT solar charge controller stands for “Most Power Point Tracking”. It will measure the Vmp voltage of the panel, and down-converts the PV voltage to the battery voltage. Because energy into the charge controller equals power out of the charge controller, when the voltage is dropped to match the battery bank, the present is raised, so you might be using more of the available power from the panel. You should use a higher voltage solar array than battery, like the 60 cell nominal 20V grid-tie solar panels which can be more readily available. With a 20V solar panel, you possibly can charge a 12V battery bank, or in series can charge up to a 24V battery bank, and three in series can cost up to a 48V battery bank. This opens up a complete wide range of solar panels that now can be used in your off-grid solar system.

THE KEY FEATURES OF A SOLAR CHARGE CONTROLLER ARE:

Multistage charging of battery bank – adjustments the amount of power set to the batteries based mostly on its charge level, for healthier batteries.

Reverse present protection – stops the solar panels from draining the batteries at evening when there is no energy coming from the solar panels.

Low voltage disconnect – turns off attached load when battery is low and turns it back on when the battery is charged back up.

Lighting management – turns connected light on and off based on dusk and dawn. Many controllers are configurable, allowing settings for a number of hours or all evening, or somewhere in between.

Display- might show voltage of battery bank, state of charge, amps coming in from solar panel.
