When and why do I need a charge controller?
To determine whether you require a charge controller, multiply the battery amp hour capacity by the maximum power amp rating of the solar panel. A controller is not required if the quotient is more than 200. If the number is less than 200, a controller is required. For example, if you have a 100 amp hour battery and a 10 watt panel, divide 100 by.6 (600mA) to get 166.6. Because this is less than 200, a charge controller is required. In the preceding example, if you had a five-watt panel, you divide 100 by.3 (300mA) to get 333.3.Because this is greater than 200, no charge controller is required. However, a blocking diode is still required to prevent the battery from draining to the panel at night. As a general rule, unless you have more than five watts of solar for every 100 amp hours of battery capacity, you don't need a charge controller.
What Exactly Is An MPPT Charger?
The most basic function of a solar power system is solar panels gathering energy from the sun and storing it in batteries for later use. You cannot, however, simply connect your solar panels to your batteries and expect them to charge. To get the most out of your solar panels, you'll need a charge controller to efficiently charge your batteries. The maximum power point tracking (MPPT) charge controller is the most efficient sort of charge controller.
Maximum Power Point Tracking Is It?
Before we get into how MPPT charge controllers work, it's important to understand how they got their name. The maximum power point voltage is the voltage at which a solar panel produces the greatest power. The maximum power point voltage changes depending on the surroundings and time of day. MPPT charge controllers derive their name from the fact that they monitor the solar panel and calculate the maximum power point voltage under current conditions. This is known as maximum power point tracking, or MPPT for short.
