A solar charge controller is a critical component in a solar power system, responsible for regulating the voltage and current coming from the solar panels to the batteries.
This small module will be a good choice for some portable solar power applications. Another solar charger module to consider is the “HW-845” solar charger module. This is based on the Consonance CN3767 chip specialized to charge Lead-Acid batteries. I've seen countless forum discussions about its major design flaws that many do not expect.
A solar charger is a charger that employs solar energy to supply electricity to devices or batteries. They are generally portable. Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere hours (up to 4000 Ah) capacity. Such type of solar charger setups generally use an intelligent charge controller.
A solar charge controller is essentially a solar battery charger wired between the solar panel and battery. There're two main types of solar charge controllers – PWM (pulse width modulation) and MPPT (maximum power point tracking) with the latter being the primary focus of this post. MPPT Solar Charge Controllers?
What types of solar panels are used in solar chargers?
The two dominant types of solar panels used in solar chargers are Monocrystalline and Polycrystalline. Monocrystalline solar panels are more efficient but pricier; Polycrystalline panels are less efficient but relatively cheaper. What is a Solar Battery Charger? This brings us to another interesting question: what is a solar battery charger?
The solar battery charger works just like the solar charger but directs the generated electricity to recharge batteries. It is designed to charge different sizes and types of batteries, from the small AA batteries for your flashlight to the large 12V batteries for your vehicle or boat.
What are the features of a solar power module?
The module comes with integrated MPPT (Maximum Power Point Tracking) to maximize solar energy conversion efficiency under various sunlight. Onboard integrated circuit based battery and power protection features which provide reliable power management for different types of solar projects.
