MPPT solar charge controllers are rated in amps (Output Current). To select a charge controller, you''ll need to calculate the maximum amount of current (in Amps) that the MPPT should be able to output. This max output current value is calculated by dividing the maximum system wattage (in Watts) by the minimum charging voltage of the battery bank (in …
Depending on the number and power of the solar panels to be paired with the number and voltage of the battery bank, a selection of the best size charge controller can be made. Charge controllers are rated according to amperage.
Now that we have all the information we need, let’s take a look at the results from the MPPT calculator. The MPPT calculator tells us that our solar charge controller needs to have a maximum voltage input of more than 53V, and needs to be able to put out 22.5 amps.
What a solar charge controller does Think of a solar charge controller as a regulator. It delivers power from the PV array to system loads and the battery bank. When the battery bank is nearly full, the controller will taper off the charging current to maintain the required voltage to fully charge the battery and keep it topped off.
With a 200W panel on a 12V system, the amperage calculations would be: 200W / 12V = 16.7A 16.7A X 1.25 = 20.9A So select a charge controller rated for greater than 21A array current. An MPPT controller in the 30-40 amp range would suit this 200W solar panel well. What size charge controller for a 100w solar panel? For a 100W, 12V panel:
A 10A PWM charge controller can support a 120 W solar array to charge a 12 V battery bank (120W/12V = 10A) or it can support a 240 W solar array to charge a 24 V battery bank (240W/24V = 10A). For a 240W 12 V solar array to charge a 12V battery bank (240W/12V = 20A) a 20 amp PWM Charge controller is required.
• Certain low-voltage appliances must be connected directly to the battery. • The charge controller should always be mounted close to the battery since precise measurement of the battery voltage is an important part of the functions of a solar charge controller.

PWM charge controllers are available in 10 A, 20 A, and 30 A capacities and are ideally suited for simple systems to charge 12 V and 24 V battery banks. A 10A PWM charge controller can support a 120 W solar array to charge a 12 V battery bank (120W/12V = 10A) or it can support a 240 W solar array to charge a 24 V battery bank (240W/24V = 10A).
Learn how to wire two solar charge controllers effectively in this step-by-step guide. Increase your solar power system''s capacity, efficiency, and reliability with parallel or series configurations. Ensure safety and follow best practices.
