Low battery forced charge function
Prerequisite: When the battery voltage is too low, it will go into the shutdown state automatically. Meanwhile, the
voltage between the battery box B + and B- is zero and the panel lights are off. when push the power button, the
battery run(green) LED is on ,low battery(yellow) LED is on, fault(red) LED is flashing, if the fault(red) LED still
flashing after 3 minutes, means the battery into ultra-low battery, in ultra-low power to recharge battery can only
use forced charge function.
Preparation condition before forced charging: Connect the charger or the inverter with charging capability to the
B+ and B- of the battery box to ensure charging capacity.
Forced charging step:
Step 1: Make sure the battery is in ultra-low power, please refer to "Prerequisites".
Step 2: If the battery is off, please turn on the battery and observe whether the status of the battery indicator is
run(green) LED is on, the low power(yellow) LED is on, the fault(red) LED is flashing. if it is ,do next step operating.
(If no operation is performed for five minutes from the moment you push the power button, the battery will turn off
again.)
Step 3: Push the power button (1-2S) again, if the run(green) LED is flashing, the low power(yellow) LED is on,
the fault(red) LED is on, means the battery into forces charge state.
Step 4: After entering the forced charge state, you have 90S of time to prepare for charging. battery is detected
charging during this 90S, the fault (red) is off, run LED no longer flashing (just on) after 90S, means the battery into
the normal charging mode. the battery is not detected charging after 90S,the fault(red) LED will flashing, the battery
cannot be recharged in this time, you can only start the forced charging operation from the beginning (if no operation
within 5 minutes, the battery will enter the shutdown state).

The steps of the battery boxes work in parallel
6.3.1
Cautions before Parallel:
(1)
The battery boxes voltage difference must not be greater than 2V. Otherwise, the battery boxes are not
allowed for parallel connection.
(2)
The connection between the battery boxes and the parallel box is ready.
(3)
Before activity the system, operator should check the cable connection strictly till make sure of the LINK
cable connection is hard, and check the batteries DIP switch had been setup correctly.
6.3.2
Activate the parallel batteries system
Step 1, short press the master battery box power button(1S), the master battery box RUN light on, the master
battery box is activated.
Step 2, short press the slave battery box 1 power button (1S), the slave battery box 1 RUN light on, the slave
battery box 1 is activated.
Step 3, If parallel with three battery boxes, please short press slave battery box 2 power button(1S), the slave
battery box 2 RUN light on, the slave battery box 2 is activated. Switch on dc isolators between battery and
inverter, and between batteries.
Finally, all battery boxes are activated, and the parallel batteries system is properly powered on.
6.3.3
The parallel Batteries system shutdown
Switch off dc isolators between battery and inverter, and between batteries. Long press the master battery box
power button (5s), the master battery box RUN light immediately extinguished, slave battery boxes RUN lights
