1. The above voltage corresponds to 12V system only. If a 24V system is used, please*2.
2. b01-b03 will go into equalizing charge when and only when LVD occurs. After equalizing charge, it goes directly into floating charge.
3. The corresponding parameters with "bracket identification" in the parameter table can be modified by pressing the button, but the other parameters cannot be modified.
Recommendations for Safe Use:
1.The controller is a 12V/24V controller. When installing it for the first time, please make sure the battery has enough voltage so that the controller can recognize it as the correct type of battery.
2. Install the controller as close to the battery as possible to avoid voltage drop caused by too long wire, which may affect the normal determination of voltage.
3.The controller is suitable for 12/24V lead-acid batteries, ternary lithium batteries and lithium iron phosphate batteries. Please select the appropriate battery type in the menu.
4. The controller can only use PV panel as a charge source. Do not use DC power supply as a charge source.
5. The controller will generate heat when running.
Please install the controller on a flat, well-ventilated surface.
FAQ:
Q: Why isn't charging displayed after my PV panel is connected?
A: Check if the PV panel wiring is correct, and if the connection is reversed or false; check if the PV panel voltage is too high; check if the PV panel is blocked and the voltage drops consequently.
Q: Why is the charge current so small?
A: The higher the PV panel power, and the stronger the sunlight, the larger the charge current, and conversely, incorrect PV panel voltage, and blocking by foreign object, shadow, etc. will cause the current to decrease. In addition, when the battery voltage is high, it will enter a floating charge state, at which point the charge current will also become smaller and smaller.
Q: Why won't my load light up?
A: The causes that the load is not turned on may include, the load operating mode is not set correctly. For example, the light control is set up but the load is not turned on during the day. In this case, battery is low, resulting in the controller to cut off the load, or the load is not properly connected, disconnected, burned out or the like.
Q: What if I don't need to use electricity for an appropriately long period of time?
A: If the daily power generation of the PV panels is less than the amount of electricity used by the load, it will result in a situation where the generation does not cover the consumption. In this case, it is recommended to increase the number of PV panels in order to cope with extreme rainy weather. In addition, you can increase the battery capacity, as well as reduce the wattage of the load or working hours to balance the whole system.
Q: Why does a fully charged battery run out of power after a short use?
A: The battery is close to the end of life. You can do a simple test. For example, after discharge, charge the battery by PV panel or mains. The voltage will rise very soon. Then, stop charging and turn on the load. The voltage drops very soon. This indicates that the battery performance has degraded. You should replace a battery.
