FAQ:
Q: Why MPPT PV solar charge controllers are important?
A: The MPPT solar charge controller will always run with the maximum power point, which reduce the waste of energy compared with the traditional controller. The voltage Vmp of the solar PV array will decrease as the temperature of the array increases.
Q: How does the MPPT charge controller work?
A: A MPPT solar charge controller is the charge controller embedded with MPPT algorithm to maximize the amount of current going into the battery from PV module. MPPT is DC to DC converter which operates by taking DC input from PV module, changing it to AC and converting it back to a different DC voltage and current to exactly match the PV module to the battery.
Q: How does MPPT charge controllers work?
A: An MPPT charge controller converts the solar-generated voltage into the optimal voltage so as to provide the maximum charging current to the battery. The main purpose of the MPPT solar charge controller is not only to prevent your solar power system from losing from the solar-generated power but also to get the maximum power from the solar array.
Q: What is the difference between MPPT and PWM solar controllers?
A: MPPT vs PWM Solar Charge Controller: Application. PWM Solar Charge Controller is the most common, cost-efficient and easy deployed charge controller solution for small off-grid power systems. MPPT Regulators have much more electronics components inside and are much more complex than PWM type charge controllers. PWM solar controller usually applied in a small 12V or 24V PV system.
