Recommendations for Safe Use

The controller is a 12V controller. When installing it for the first time, make sure the battery has enough voltage so that the controller can recognize it as the correct type of battery.
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.
The controller is suitable for DC12V lead-acid batteries, ternary lithium batteries and lithium iron phosphate batteries. Select the appropriate battery type in the menu.
The controller can only use PV panel as a charge source. Do not use DC power supply as a charge source.
The controller will generate heat when running. Install the controller on a flat, wellventilated surface.

**| Boost charge voltage
regulation interface (only valid for b04, b07)When the battery voltage rises to this set voltage, PWM charging is enabled.During normal charging, the arrow indicator is always on, and after entering float charging, the arrow indicator is slowly flashing.
Setting recommendation: It is recommended to keep the default value.
Setting method: same as above.
**| Over discharge recovery voltage
regulation interface (LVR)When the controller turns off the load due to low voltage, the load will not be turned on until the battery voltage rises to the set voltage again.
Setting recommendation: It is recommended to keep the default value.
Setting method: same as above.
**| Over discharge voltage
regulation interface (LVD)The controller will automatically cut off the load output when the battery voltage drops below this voltage.
Setting recommendation: It is recommended to keep the default value.
Setting method: same as above.
| Light control ON/OFF threshold (PV panel voltage)
In light control or time control mode, when the controller detects that the voltage of the PV panel is less than this set value, it will turn on the load after a delay and otherwise turn off the load. At night, if the ambient light around the solar panel is too bright, the solar panel output voltage will become higher, which will cause the controller to automatically turn off the load. At this point, it can be adjusted somewhat by this value.
Setting recommendation: It is recommended to keep the default value.
Setting method: same as above.
**| Light control ON/OFF delay threshold (in seconds)
When the controller detects that the PV panel voltage is lower than the set threshold, it will delay to turn on the load. Such time value can be used to prevent turning off the lamp due to erroneous judgment caused by the interference of car lights or lightning at night.
Setting recommendation: It is recommended to keep the default value.
Setting method: same as above.
**| Short-circuit protection setting
Some inductive or capacitive loads may draw a large current at the moment of start-up, which may trigger the short circuit protection of the controller and cause the output to shut down. In this case, the user can turn off the short- circuit protection. SC.F is Off, SC.n is On, and the default is On.
Setting method: same as above.
**| PWM charge settings (only valid for b04, b07)
PWM is likely to cause the system to produce noise and interference. Especially when a lithium battery with BMS is used, PWM charging may trigger BMS protection and cause system failure. Therefore, the customer has the option to turn PWM off. In this mode, once the battery is charged to the preset voltage (interface 7), the controller will stop charging immediately, and restart charging after the battery voltage returns. PoF is Off, Pon is On, and the default is On.
Setting recommendation: It is recommended to keep the default value.
Setting method: same as above.
**| Load light control mode settings
Lc1 indicates that the load is working at night, Lc2 indicates that the load is working during the day, and the light control has priority over the time control to turn off the load. Lc3 indicates that the load is working at night, Lc4 indicates that the load is working during the day, and the time control has priority over the light control to turn off the load. Example: If it is set to 16H, since the night/day length is only 12 hours, Lc1/2 will run for 12 hours only, and Lc3/4 will run for 16 hours.The default is Lc1.
Setting method: same as above.

When the solar panel voltage exceeds 50V, the controller will stop charging to protect the internal circuitry. When the voltage is below 45V, charging resumes.

FAQ

Q1: Why isn’t charging displayed after my PV panel is connected?

A1: 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

Q2: Why is the charge current so small?

A2: 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.

Q3: Why won't my load light up?

A3: 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.

Q4: What if I don’t need to use electricity for an appropriately long

period of time?

A4: 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 addition, you can increase the battery capacity, as well as reduce the wattage of the load or working hours to balance the whole system.

Q5: Why does a fully charged battery run out of power after a short use?

A5: 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.
