The Zamp Solar 30 Amp 5 Stage Digital Deluxe Solar Charge Controller # ZS-30A has PWM or Pulse Width Modulation, which is a digital signal that is used to control power applications and has 5 stages of charging for best battery health and longevity. This controller can support the typical types of deep cycle batteries – Lithium (LiFePO4 & LTO), WET, GEL, AGM and Calcium. We pre-set the controller at the factory according to what batteries are installed and the charge controller will automatically regulate and charge the batteries according to its pre-programmed state. This makes life much easier for you so you can concentrate on camping instead of programming and maintaining a charge controller.
-
LCD screen displays battery voltage, charging current, charging capacity, battery types and fault codes.
-
LED light indicators show charging status and battery condition.
5 stages of charging:
-
Level 1
– Soft Charge – When batteries suffer an over-discharge, the controller will softly ramp the battery voltage up to 10V.
-
Level 2
– Bulk Charge – Maximum current until batteries rise to Absorption Level.
-
Level 3
– Absorption Charge – Constant voltage charging (battery is over 85%).
-
This stage takes longer than any other stage to complete. You will typically see your battery status remain in this stage unless you are not using the camper. The full battery indicator is about the last 2% and while running lights and other components it will remain in the absorption stage. *Battery volts displayed during this stage are charging volts not actual battery volts.
-
Level 4
– Equalization Charge – Only for WET battery or Calcium battery type. When the battery is deeply drained below 10V, it will automatically run this stage to bring the internal cells to equal states and fully complement the loss of capacity. (Gel and AGM batteries do not run Equalization Charge).
-
Level 5
– Float Charge – Battery is fully charged and maintained at a safe level. Fully charge is more than 13.6V.
Zamp Charge Controller & SeeLevel II (Battery Volts)
-
Both systems will display charging volts rather than actual battery volts when power is being supplied to the batteries.
Customer interaction
-
The charge controller has 2 buttons. One button labeled Amp/Volts can be used to scroll through relevant information
Amp/Volt Button
-
Current battery volts or charging volts
-
Current Amps being supplied to the battery (Initial startup will be lower amps and slowly increase to maximum output depending on sunlight available.
-
Current total of Amp Hours supplied within the 24 hour timeframe. This setting will reset with every 24 hour period.
-
Current Battery Temperature. (Displayed in Celsius). This is used by the charge controller to monitor the battery.
Battery Type Button
-
This is pre-set at the factory based on the type of batteries installed and should only be changed if you replace your batteries with a different battery type.
