1) PV Power
：
This interface show the solar panels current output power.
2) Accumulated Charging Power(AH): Accumulate the charging power of this system. Long
press“→”button to reset.
3) Accumulated Discharging Power(AH): Accumulate the discharging power of this system.
Long press“→”button could reset.
4) Float Voltage: When the battery voltage reach this set point, the controller will start constant
voltage charging mode, limit the rising of battery voltage, decrease the charging current, and
keep the battery in full condition. Press “←”button enter into menu interface of float voltage.
Long press “←”button≥5S, the parameter in the main interface will flash, and here is setting
up state. Loose the button, and short press “←”or“→”could modify the data. After set the
needed data, long press“←”≥5S to save the data and exit. If no operation in 20s, it will
automatically back to the main interface.
5) Boost Voltage: When the battery voltage is less than 12.6V, the constant voltage will auto
reach up to 14.4V and back to float voltage after 2 hours’ charging.
6) Low Voltage Reconnect Voltage(LVR): After the controller detect the low voltage of load and
stop the output, battery voltage must be higher than LVR voltage if it reconnect the output.
Or press “→” in the main interface to release. The procedure is the same as (4).
7) Low Voltage Disconnection Voltage(LVD): When the controller detect the battery voltage is
less than LVD point, the output will be immediately shut down. At the same time, the status
of controller is in lock. Users have to charge the battery, and the load will reconnect when
the battery voltage is higher than LVD voltage or press “→” in the main interface to release.
The procedure is the same as (4)
8) Load Working Mode Selection: The system default load working time is 24h. When the Load
Working Time is set to 24hours, the load will keep working 24hours if there is no fault. When
the load working time is set to ≤23H, it means starting the load timer or sensor function. The
procedure is the same as (4). If the battery capacity is enough, the load will start-up at
sunset and work in set hours or stop working till sunrise.
When the load come into timer or sensor mode, if the set working time is more
than actual night time, the load output will be closed at sunrise, although the
working time is not reach the set hours. For example, the local actual night
time is 10hours, and the working time user set at night is 12hours. But when
the sunrise 10hours later, the output will be closed automatically.
No matter how many hours after the sunrise will be zeroing and the load will
work with next sunset.
9)
Controller inside Temperature detection:
When the inside temperature of controller is
more than 75
℃
, the charging current will be reduced. It will stop charging when the
temperature exceed 85
℃
.
10) Battery Type Selection: 3 types battery data
in the internal system
. Different battery refer to
different parameter. (Default SEL battery parameter)
Attention: About the control parameter of battery, we have taken every working condition
into consideration. Hence, if customers want to adjust the parameter, please refer to
battery suppliers’ suggestion, or unreasonable adjust will destroy battery.

Solar Panel Short Circuit and Reverse Connected Protection
When the solar panels have input short circuit or reverse connection, the controller will be
stopped charging immediately until correcting the faults.
Solar Panel Over Voltage Protection
When solar panel input voltage is more than 100V, the controller will be stopped charging
immediately until the input voltage is less than 100V.
Battery Reverse Connection Protection
If the battery reverse connect, the controller won’t be damaged and will normally work after
corrected the connection.
Battery Over Voltage Protection
When the voltage of battery is more than 16.5V, the controller will be automatically stopped
charging and discharging to avoid the damage of the battery and loads.
