Solar Controllers

MODELs and types of Solar Controllers :

The STECA PR Solar Charge Controllers have been specially designed for operation in difficult environments with high salt, moisture and dust contents.

The PR 2020 IP is equipped with a large LCD display that shows the current state of charge (SOC) as a percentage and graphically in the form of a tank. This visual representation also provides operating parameters, failure messages and self-test.

The “auto-adaptive” state of charge algorithm results in optimal battery maintenance and control over the module output of up to 480 Wp, which can be connected to it.

Manufactured according to ISO 9001 and 14001, RoHS, European Standards and DIN IEC 68 part 2-30 (use in tropical areas).

PRODUCT CHARACTERISTICS

  • Charge controller:
  • This controller is responsible for controlling the battery charging by using the solar power system.
  • The drive has an up to 60 Amp capacity of current of the photovoltaic array (FV) to 12, 24 or 48V
  • Discharge controller:
  • This controller has the function of controlling the discharge of the battery, cutting the consumption current if the battery voltage is too low.
  • It prevents damages of the battery by over-discharges.
  • Battery display:
  • LCD display allows to show the state of battery:
  • Battery voltage (V).
  • Charge and discharge current (A).
  • Amp-hour counter (Ah).
  • Battery state of charge (%).
  • PC connection to download historic data.
  • Overvoltage protection:
  • Located at solar module inputs to protect installation against transient overvoltage caused by storms.
