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
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.
