How to Choose the Right Solar Charge Controller?
The trend between builders and buyers is to build a building that is both architectural and environmentally friendly. People are now understanding and adjusting the way they use renewable resources. One of the newest methods is to install solar systems; in this way, they can store solar energy and use it as an alternative to standard power connections.
There are several benefits to installing a solar system at home. In this way, you can pay less for utilities and continue to donate to Mother Earth. However, just installing a solar system is not enough, you need to make sure that the energy is properly consumed and stored safely. Solar cells are an integral part of solar systems. You can't rely entirely on sunlight or generators; you need a solar cell to store solar energy, even on cloudy days.
Of course, Solar cells can be considered as energy tanks or storage rooms for solar systems. It clearly defines the chemical composition, making it an ideal choice for solar systems. But solar cells also require proper maintenance, otherwise, they may fail prematurely or shut down the entire system. Continued overcharging of the battery can adversely affect them. There is a charge controller here to prevent the battery from overcharging.
Is the charge controller really necessary?
The charge controller is an important part of almost any power system that charges the battery, whether it is solar, hydro, wind, fuel, etc. Its purpose is to keep the battery charged and safe.
The solar charge controller regulates the voltage and current flowing from the solar panel to the solar cell. If the non-self-regulating solar series is installed on a lead-acid battery without over-charge protection, the battery life will definitely be affected.
A simple charge controller consists of a transistor that shunts the PV charging circuit. The charge is turned off at a preset high voltage. After touching the preset reconnect position, the shunt will open to resuming charging. The composite controller uses PWM (Pulse Width Modulation) or MPPT (Maximum Power Point Tracking) to ensure that the battery is fully charged. First, 70%-80% of the battery capacity is just a switch, but the last 20%-30% is more complicated, so more attention is needed.
How does the solar charge controller work?
The solar charge controller maintains the solar system battery by preventing overcharging or undercharging of the solar system battery, thereby ensuring maximum battery life.
The solar charge controller controls the 16-20 volt output of the 12 volt solar panel to reduce it to the minimum possible voltage required to maintain the battery at its highest operating level. This voltage is typically 10.5 to 14.6 volts, depending on the battery type, battery temperature and battery state of charge at any particular point.
Various types of charge controllers come in a variety of shapes and sizes; from 4.5 amp units to 60 amp programmable units with a computer interface. Most charge controllers support simple LED or digital displays. However, some of the latest charge controllers offer a built-in computer interface for display and control.
