Product Introduction:
SL03 series controllers are kinds of intelligent multi-functional solar charge and discharge controller. This series adopts the new 32bit microprocessor to collect and compute various parameters, which is much more accurate and speedy than the former 8bit microprocessor. The customized LCD with wide temperature range is with vivid operation interface; the latest proprietary technology solves the problem of voltage display of solar panel. Nearly all parameters can be shown and set up flexibly. All of the multi-meter and other voltage and current instruments can be replaced by this controller, which can satisfy your various demands.
Product Features:
Newly Upgraded: Data collection by 32bit microprocessor with 4096 resolution ratio is much more accurate than the former 8bit microprocessor with 1024 resolution ratio.
Newly Upgraded: The voltage of solar panel can be shown and checked.
Newly Upgraded: The results and states of each monitoring parameters can be automatically showed by turns (automatic-scanning).
Newly Upgraded: Light-operated sensitivity is set flexibility which can recognize day and night reliably according to the voltage of solar panel.
Newly Upgraded: Floating charge voltage can also be set, which can be especially applied to charge and discharge at the same time, controlling the voltage of battery flexibly
Newly Upgraded: The charge-discharge parameters of wide range can be adjusted flexibly, which is suitable for various kinds of battery, such as lithium battery. The old and new battery can all be applied to.
Newly Upgraded: Automatic temperature compensation and adjustable compensating parameter, for example, the lithium battery can choose the closing temperature compensation.
Newly Upgraded: Flame-retardant plastic shell
Newly Upgraded: LCD display screen with wide temperature range is with visual graphic symbol display
Newly Upgraded: 5V 1A USB output for mobile device charging

 ** Precaution**:

  • Please read user manual after you receive the item. 
  • Double check polarity(+/-) after connect each cable to terminal. Use multimeter to double check polarity & voltage.
  • Do not reverse polarity & sort circuit. Damage caused by improper installation / Burning will void the warranty!
  • Make sure the solar panel output is within solar controller specification.
  • Make sure connect battery 1st before solar panel & load so that controller can determine solar system voltage. Battery should in normal voltage range.
  • Do not connect AC power Inverter to solar contoller load output, connect directly to Battery.
  • Although this controller has multiple protective measures, but this is not panacea!
