Maior 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
| battery type | mode |
|---|
charging priority
charging ferquence
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. 1st led is the battery type setting.
| Number shows | Battery type |
|---|---|
| 1 | Sealed battery |
| 2 | Gel battery |
| 3 | Flooded battery |
2. 2nd 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. 3rd led is for charging frequency.
| Number shows | PWM Charging frequency |
|---|---|
| 0 | 25Hz(pre-set) |
| 1 | 50Hz |
| 2 | 100Hz |
TROUBLESHOOTING
- LED blinking, short circuit, check the PV and battery, and make sure that they are in correct connection
- LED slowly flashing, fully charged
- LED ON, on charging
- LED frequent flashing, with battery, no charging
- LED OFF, no battery or over voltage
