In its basic forms, solar PV is a very straightforward proposition. Hook a solar panel up to a DC load and it will run until the sun goes down. Connect solar panels to a grid-tied inverter and, as long as the sun is shining, power will be sent to the utility. It''s all fairly easy — until the sun stops shining.
This can be achieved if the nominal voltage of the panel is lower than 17-18V, and if the solar panel is a lot smaller than the charging battery e.g.. a 10W panel charging a 100Ah battery. There are many different types of controllers on the market. Choosing the right controller depends on the solar power system you would like to generate.
The first step is to choose the type of solar charge controller. PWM and MPPT are the two technologies available on the market. As previously mentioned, PWM is less efficient than MPPT (around 16% for small systems and more for larger PV arrays). Therefore, we can only recommend purchasing an MPPT solar charge controller.
The main role of a controller is to protect and automate the charging of the battery. It does this in several ways: 1. REDUCING THE VOLTAGE OF YOUR SOLAR PANEL Without a controller between a solar panel and a battery, the panel would overcharge the battery by generating too much voltage for the battery to process, seriously damaging the battery.
For 12V battery systems, the maximum input power for solar panels should not exceed 360W. It's essential to avoid surpassing this limit to prevent any damage to the controller. Key Point 4. It's crucial to ensure that the output current of the controller does not exceed the battery's maximum charging current allowed.
Regulate the power output of your solar panel. Properly charge the battery. There are currently 2 types of solar charge controllers: PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking). The coming sections will describe how they work and what the main differences between the 2 technologies are.
Having two controllers can optimize the total power output. In many cases, individuals who install solar power systems will later go on to expand these systems. It isn’t uncommon for the capacity of the expansion to go well over what the existing charge controller can handle.
