About The Spectra Regulators

£28.96£99.95

Spectra is Marlec’s range of solar charge controllers for PV systems. These intelligent 10A, 20A and 30A regulators use Pulse Width Modulation to deliver bulk, absorption, float and equalised charging regimes ensuring batteries get fully charged and are maintained in good condition. Two MPPT options available in 10A and 20A for achieving even higher energy yield of your solar panel.

Spectra PWM Solar Regulators

All models include an easy to view LCD display with simple to operate push buttons for scrolling and settings where needed. The 10A and 20A models include 2 USB charge points, 5V 1A rated, making these Spectra models excellent value for the user. Standard features include:

  • User adjustable voltage setting
  • Automatic system voltage setting
  • Low voltage disconnect feature
  • Temperature compensation
  • Over current and reverse discharge protection
  • Push button operation
  • Dusk to dawn switching feature

Simple to Connect Spectra Regulators

The large terminals accept cables up to 10mm2 (16mm² for the 30A model).

Auto Detection Voltage Setting

Connect the battery first for the regulator to auto-detect your intended operating voltage to 12V or 24V.

USB Connection Points: 10A & 20A PWM Models Only

Display Screens

The built in display keeps the system user informed about the current operating mode and condition of the battery. It is also used to programme voltage settings and set up of the lighting function. A few examples are:

Indicates the battery voltage levels and the night light function is on

Indicates that solar energy is charging in the Absorption phase. No load is connected.

Indicates that the battery is fully charged and receiving solar energy to float charge to maintain it. No load is connected.

Indicates that the battery is in a critically low state of charge and the Low Voltage Disconnect has shut down the load. No solar energy is being generated at this time.

Spectra MPPT Solar Regulators

The new MPPT solar controllers use full digital technology to efficiently track the Max Power Point at 99.9% to boost the energy yield of your solar panels. Multi-stage charging ensures good battery conditioning to improve the lifetime of batteries too.
