Major feature of duo-battery controller

(Note: connect the components as the 1-6)

	Connect with the battery #1
	Connect with the battery #2
	Connect with the PV.

Remote temp. sensor
A connection point for RTS(option) to remotely monitor battery temperature
Local temp. sensor
Measures ambient temperature. Battery regulation is adjusted accordingly
For battery 1
Provides charging & battery status and errors
For battery 2
Provides charging & battery status and errors
Remote meter connection
A communication port for the remote meter
Note: where is no RTS, the controller calculate the data which got from the local temp. sensor. The controller will come to RTS automatically when the RTS was connected.

SETTING MODE

Three leds flashing, each LED express different specifications, choose the LED first according to the following information, and then press the switch for 5 seconds until the number flashing, choose one number as you need, and leave it and the number you set will be saved.

1. 1 st led is the battery type setting.
   

   Number shows	Battery type
   1	Sealed battery
   2	Gel battery
   3	Flooded battery

2. nd 2 led is for charging priority, only set the percentage you want for battery #1, the controller will automatically calculate the rest for battery #2.
   

   Number shows	Battery #1 charging	Battery # 2 charging
   0	0%	100%
   1	10%	90%
   2	20%	80%
   3	30%	70%
   4	40%	60%
   5	50%	50%
   6	60%	40%
   7	70%	30%
   8	80%	20%
   9	90%(pre-set)	10%

   Note: in the normal charging status, the controller will divide the charging as the setting. While battery #1 is fully charged, more charge current will be diverted to battery #2, and return to the setting charging automatically when the battery #1 is in low voltage.
   When the controller detects there is only battery #1, all the charging will go to the battery #1 automatically.

3. rd 3. 3 led is for charging frequency.
   

   Number  shows	PWM  Charging  frequency
   0	25Hz(pre-set)
   1	50Hz
   2	100Hz

TROUBLESHOOTING

1. LED blinking, short circuit, check the PV and battery, and make sure that they are in correct connection
2. LED slowly flashing, fully charged
3. LED ON, on charging
4. LED frequent flashing, with battery, no charging
5. LED OFF, no battery or over voltage
