SPECIFICATIONS
SOLAR CONTROLLER
3 Stage Charging – Built in regulator to prevent your battery from being overcharged.
Overcharging occurs when the charge voltage is unregulated. This can result in premature
battery failure.
The regulator also prevents your battery from being under charged, in the solar energy field,
battery undercharge always occurs, especially on some Conventional lead – acid or Calcium
batteries; The unit provides an automatic Equalization feature for deeply drained Conventional
lead acid batteries or Calcium batteries.
It keeps the battery fully charged by using a process called “floating”. This means the controller
will stop charging when the battery is full and will automatically start charging the battery as
required. This process will also reduce water loss and help prevent the battery from ‘drying out’.
Discharge Protection – Protects your battery from discharge at night. Under low light or no
light conditions the solar panel voltage could be less than the battery voltage. The unit contains
a special circuit which prevents current flowing back from the battery and into the solar panel.
LED Indicators – Coloured LED’s to easily indicate the operational status and battery conditions.
Unit Protection – Multi charging protects against reverse polarity, short circuit, over temperature,
over voltage, etc.
