20A RV MPPT Solar Charge Controller Auto 12V 24V BLE Module Solar Panel Regulator for Liquid Gel and Lithium Battery Motor Homes
Overview:
Win series solar controller is based on an advanced maximum power point tracking (MPPT) technology developed, dedicated to the solar system, the controller conversion efficiency up to 98%.
The controller can rapidly track the maximum power point(MPP) of PV array to obtain the maximum energy of the panel, especially in case of a clouded sky, when light intensity is changing continuously, an ultra fast MPPT controller will improve energy harvest by up to 30% compared to PWM charge controllers.
Outstanding features:
1.Innovative Max Power Point Tracking(MPPT) technology, tracking efficiency >99.9%
2.Full digital technology, high charge conversion efficiency up to 98%
3.LED indicator for easy to read charging state and battery information
4.12/24V automatic recognition
5.Liquid, Gel, AGM and Lithium battery for selection
6.The separate ports for remote temperature sensor, make battery temperature compensation more accurate
7. Four stages charge way: MPPT, boost, equalization, float
8. Automatic over-temperature power reduction function
9. Dual automatic restriction function when exceeding rated charging power and charging current
10. Android APP version for Bluetooth communication
11. Common negative design
12. Perfect EMC & thermal design
13. Full automatic electronic protect function
Strature and Coonection:
Charging Mode:
MPPT Charge:the battery voltage has not yet reached boost voltage and 100% of available solar power is used to recharge the battery.
Boost Charge:When the battery has recharged to the Boost voltage setpoint, constant-voltage regulation is used to prevent heating and excessive battery gassing.
Float Charge:In Float stage, loads can continue to draw power from the battery,It will reduce the temperature of battery and prevent the gassing, also charging the battery slightly.
Equalization Charge:Equalizing charge increases the battery voltage, higher than the standard complement voltage, which gasifies the battery electrolyte.
Protection:
| Protection |
Description |
| PV Over Current |
The controller will limit charging power in rated charge power. An over-sized PV array will not operate at maximum power point. |
| PV Short Circuit |
When PV short circuit occurs, the controller will stop charging. Remove it to start normal operation. |
| PV Reverse Polarity |
Fully protection against PV reverse polarity, no damage to the controller. Correct the connection to start normal operation. |
| Battery Reverse Polarity |
Fully protection against battery reverse polarity, no damage to the controller. Correct the connection to start normal operation. |
| Battery Over voltage |
If there are other energy sources to charge the battery, when the battery voltage exceeds 15.8/ 31.3V, the controller will stop charging to protect the battery from overcharging damage. |
| Battery Over discharge |
When battery voltage drops to the setting voltage point of low voltage disconnect ,the low voltage protection indicator of the controller will flash. |
| Over Temperature Protection |
The controller detects the internal temperature through internal sensor, when the temperature exceeds the setting value, the charging current will lower d own followed by the decrease of temperature, so as to control the controller's temperature rise, when the internal temperature exceeds the setting over temperature protection threshold, the controller stops working and restores after the temperature is lowered. |
| Damaged Remote Temperature Sensor |
If the temperature sensor is short- circuited or damaged, the controller will use the internal temperature for charging temperature compensation. |
