SUNBEAM Mini MPPT Charger / portable

This compact mini MPPT charger is ideal for mobile use, whether on board or when camping. The MPPT technology ensures that the maximum module output can be utilised in the vehicle electrical system or stored in the battery. The standardised 2-pin SAE plug connections of the charge controller and the adapter cables included in the delivery contents make connecting the solar module, Mini-MPPT and on-board power supply or battery child's play.
The Mini-MPPT works with an advanced 4-stage charging characteristic. Settings can be made via a multifunction button. The controller can be set to charge standard lead-acid/AGM**, GEL or LiFePO4 batteries with just a few presses of a button. The function button also activates a small, innovative LC display and shows you all relevant information about the charging process, such as battery voltage, charging current, device temperature (°C & °F) and error codes. The display switches off automatically approx. 20 seconds after the last button is pressed. Other small LEDs continue to operate and indicate the charging progress and the selected battery type. The regulator is protected against overcharging, overheating and reverse polarity. The following accessories are included:

• 1x solar module connection adapter (2x 18AWG***) with SAE and MC4 connectors, length approx. 20 cm
• 1x extension cable (2x 18AWG) with 2 SAE plugs, length approx. 100 cm
• 1x battery connection cable (2x 18AWG) with crocodile clips, length approx. 100 cm
• 1x vessel electrical system connection cable with cigarette lighter plug, length approx. 100 cm,
  A red indicator LED and an F15A miniature fuse (6.3x32 mm) are integrated in the cigarette lighter plug
• 1x elastic protective cover

** With a permanent connection to the battery, the charging voltage is increased to 14.6 V every week with the STD characteristic curve in order to bring the battery cells to the same state of charge or to desulphate them. Check whether 14.6 V is suitable for your AGM battery. This weekly voltage increase does not occur with the GEL characteristic curve.
*** 18 AWG = 0.823 mm², you should select a larger cable cross-section for possible extensions.


Operation
Briefly pressing the multifunction button activates the LC display. Additional short button presses enable you to choose between displaying the battery voltage/charging current, the temperature of the Mini-MPPT or the error codes.
Pressing and holding the multifunction button activates the mode for setting the battery characteristic curve. Further long button presses are used to select between STD (standard lead acid) GEL or LFP (LiFePO4). Small LEDs signal the set battery type.

Battery type	GEL	STD	LFP (LiFePO4)
Boost Charge Voltage	14.2 V	14.4 V	14.4 V
Float Charge Voltage	13.8 V	13.8 V	No float charge
Equalizing Charge Voltage	No EQ	14.6 V	No EQ
Boost Charge Recovery Voltage	13.2 V	13.2 V	-
Over-Discharge Recovery Voltage	12.6 V	12.6 V	12.6 V
Over-Discharge Voltage	11.1 V	11.1 V	11.1 V
Temperature Compensation (12 V Battery) -3 mV per 2 V cell at 1 Kelvin temperature difference	-18mV/K	-18mV/K	No temperature compensation

Error codes

Error code	Error
E00	No error
E01	Deep discharge
E02	Battery overvoltage
E06	Charge controller is overheated
E10	Solar overvoltage
E13	Solar input connected with reversed polarity
E16	Battery connected with reverse polarity

If an error code is displayed, you should disconnect the charge controller from the PV module and the battery, rectify the error and then re-establish the connections.
