Frequently Asked Questions
- What does PWM stand for?
PWM stands for Pulse Width Modulation and refers to a type of digital signals used to control electrical circuits. The signal has two states: ON and OFF. The amount of time used during each state can be varied. PWM is used in many applications such as motor drive circuits.
- What is a Class 1 Div 2 certified solar charge controller?
This refers to a solar charge controller that is safe to operate in certain hazardous locations. Hazardous locations are classified Class 1 if flammable gasses and vapors may be present in the area. Divisions define the likelihood of the hazardous material being present in a flammable concentration. Phocos provides several Class1 Division 2 solar charge controller options.
- What is the main objective of a solar charge controller?
The main goal of a solar charge controller is to extend and maximize the lifetime of batteries by controlling their charging and discharging mechanism.
- What are the main tasks of solar charge controllers?
A solar charge controller is a key component in a solar system solution to maximize the investment of all equipment. A high-quality solar charge controller optimizes performance, reducing periods of power disruptions and potential problems.
- Battery charging
- Battery Deep-discharge protection
- Battery Over-charging protection
- Battery State of charge monitoring
- What type of solar charge controllers exist?
- PWM or Pulse Width Modulation (Series and Shunt)
- MPPT or Maximum Point Power Tracking
- What is CV and CC for battery charging?
CC stands for Constant Current and CV stands for Constant Voltage. The charging profile of a battery consists first of a CC phase, where a constant current is applied to the battery to increase its voltage up to a certain level. In solar systems, this current is the maximum current that can be delivered from the PV panel (this depends on the charge controller technology used) and may not be literally constant because of external conditions that affect the panel current such as irradiance. The CC phase is then followed by a CV phase when a certain target voltage is reached. During this phase, the voltage is kept constant.
