1. Basic information
1.1 Product overview and features
Our products have been strictly tested and inspected before leaving the factory. If
you find any abnormalities in the equipment, please contact the provider.
EBW-05-10 wall-mounted energy storage battery is a device used to store energy in
a photovoltaic solar system.
Product features: This product is composed of high-quality lithium iron phosphate
aluminum shell cells, high-efficiency BMS, and anti-static metal shell. The square
aluminum shell cell has high stability and fast heat dissipation. The BMS effectively
manages overcharge and over discharge, short circuit, and over temperature. The
thickened metal shell has better protection performance.
Features of the system: EBW-05 can provide 100A continuous discharge and 100A
charging capacity (recommended charging below 100A); EBW-10 can provide 200A
continuous discharge and 200A charging capacity (recommended 100A) .It supports
6000 cycles of 80% DOD. A larger capacity battery pack can be formed by parallel
connection to meet the long-term power supply needs of users. The closed line design
is adopted to effectively prevent dust and mosquitoes from blocking the interface and
increase the safety of use.

2.6 Electrical interface check
Devices that connected directly to the batteries can be user equipments, power
supplies,and other power supplies.
Please check if the user's PV power generation equipment, power supplier or other
power supply equipment has a DC output interface, and the voltage meet the
requirements of the inverter.
And check the maximum discharge current capability of the DC power interface of the
user's photovoltaic power generation equipment, power supply or other power
supply equipment should be greater than the maximum charging current of the
products.
2.7 Electrical installation
Before connecting the power cables, using multi meter to measure cable continuity，
short circuit, confirm positive and negative, and accurately mark the cable labels.
Measuring methods:
Cable availability: select the buzzer and use the probe to measure the ends of the
same color cable. If the buzzer calls, it means the cable is available.
Short circuit judgment: choose multi meter resistor file, probe the same end of
positive and negative pole, if the resistor shows infinity, means that the cable is
available.
After visual testing of power line is connected well, the positive and negative poles of
the batteries shall be connected respectively to the positive and negative poles of the
opposite terminal.
It is better to add a circuit breaker between the inverter and the batteries system. The
selection of the circuit breaker requires:
Voltage: U＞60V
Current: | =Inverter Power
43V

2.8 Use, maintenance and troubleshooting
Batteries system usage and operation instructions
After completing the electrical installation, follow these steps to start the batteries
system
1.Refer to 1.3, Press the self-locking switch to ON position, The display screen and
indicator will light up
2.After the indicator self-test, the RUN indicator will light and the SOC indicator will
be on.
Note:
1. After pressing the power button, if the batteries status indicator on the front panel
continues to be red, please refer to the "3.5 Alarm description and processing ".If the
failure cannot be eliminated, please contact the dealer timely.
2. Use a voltmeter to measure whether the voltage of the circuit breaker batteries access
terminal is greater than 43V, and check whether the voltage polarity is consistent with the
inverter input polarity. If the circuit breaker batteries input terminal has a voltage output
and is greater than 43V, then the batteries has started normal work.
3.After confirming that the batteries output voltage and polarity are correct, turn on the
inverter, close the circuit breaker.
4 Check if the indicator of the inverter and batteries connection (communication
indicator and batteries access status indicator)is normal. if it is normal, successfully
complete the connection between the batteries and the inverter. If the indicator light is
abnormal, please refer to the inverter manual for the cause or contact the dealer.
