MPPT Solar Charge Controllers Explained

For an MPPT charge controller to work correctly under all conditions, the solar panel operating voltage (Vmp), or string voltage (if the panels are connected in series) should be at least 5V to 8V higher than the battery charge (absorption) voltage. For example, most 12V batteries have an absorption voltage of 14 to 15V, so the Vmp should be a

6 FAQs about [Solar panel connected to controller voltage]

Can I connect a solar panel to a charge controller?

If you connect the solar panel to a charge controller first, it may not initialize correctly. After you've connected the charge controller to the battery, it is now safe to connect it to the panels. Out of the junction box of a panel come two cables, a positive and a negative.

How does a solar panel charge controller work?

If you have several solar panels, like on the diagram, the positive cable of one panel usually goes to the negative terminal of the adjacent one. Then, the negative cable of the first panel and the positive cable of the last panel go into the charge controller.

What is a solar controller & how does it work?

How many volts can a solar charge controller handle?

A solar charge controller is capable of handling a variety of battery voltages ranging from 12 volts to 72 volts. As per the basic solar charge controller settings, it is capable of accommodating a maximum input voltage of 12 volts or 24 volts. You need to set the voltage and current parameters before you start using the charge controller.

How do I choose a solar charge controller?

The solar array should be able to generate close to the charge rating (A) of the controller, which should be sized correctly to match the battery. Another example: a 200Ah 12V battery would require a 20A solar charge controller and a 250W solar panel to generate close to 20A. (Using the formula P/V = I, then we have 250W / 12V = 20A).

How do I connect a charge controller to a solar array?

Turn the charge controller on: it should be able to measure the charge of the battery. In the user manual of a charge controller, there should be a wiring diagram, which you can consult if in doubt. It’s advised to wire the controller to the battery first before connecting it to a solar array.
