1. Safety Precautions
During product installation, operation, and maintenance, electrical safety regulations and related
operating procedures must be observed, otherwise it may cause personal injury or product damage.
The safety precautions mentioned in the manual are only a supplement to the safety regulations.
The manufacturer does not assume any responsibility caused by violation of general safety
operation requirements or violation of safety standards for design, production and use of
equipment.
Please ensure the following before use:
➢Lithium batteries should be kept away from water, dust and pollution sources. Please install the
lithium battery in a well-ventilated environment.
➢Ensure that the positive (+) and negative (-) polarities of the lithium battery and the charging
and discharging equipment are correctly connected.
➢Ensure that all cables have good electrical characteristics and suitable wire diameter.
➢Avoid direct sunlight.
➢Do not connect the DC output with lithium batteries in parallel.
➢Do not short-circuit the lithium battery output interface.
Especially keep these rules:
➢Do not expose the Energy Hub to water or fire for risk of electrocution or explosion.
➢Do not push any objects into the hub or crush the unit in any way.
➢Do not open the Hub without prior permission.
➢During use, when the system needs to be moved or rewired, the power must be completely cut
off and the system must be completely shut down, otherwise there will be a risk of electric
shock.
➢In order to avoid fire and electric shock, it is forbidden to use damaged or too small cables.
General actions to be taken by the user if these dangers occur:
➢When the electrolyte of the lithium battery leaks, it is necessary to prevent the electrolyte from
contacting the skin or eyes; if it has been in contact, please wash it with water in time and seek
medical attention as soon as possible.
➢When encountering a fire, please use a dry powder fire extinguisher to extinguish the fire. The
use of a liquid fire extinguisher may cause secondary hazards.
Disposal or recycle
Disposal and recycling of lithium batteries should comply with local, state, and
federal laws and regulations. Mixed treatment with other (industrial) waste is
prohibited.

3) Dry contact output function
➢Dry contact 1
The default setting of SOC ≤5% (5%~50% can be set) will activate the output relay dry contact for
starting the engine.
＝100% (10%~100% can be set) will break the relay output dry contact.
Wiring instructions：
1. The output dry contact Cinterface is connected to the negative terminal of the DC load or the
negative terminal of the inverter
2. Output dry contact NO interface is connected to Engine Start controller
➢Dry contact 2
When the dry contact 2 connect to the remote of inverter, it will control the inverter power on or off. If
the system is turned off，the inverter will be closed via Dry contact2. If the system is turned on
and SOC ≥5%(5%~50% can be set)，the inverter will be turned on via Dry Contact2, SOC≤0%
(0%~45% can be set, the SOC of inverter is turned on≥the SOC of inverter is turned off +5%) , the
inverter will be turned off via Dry Contact2.

Energy Hub User Manual

OR
➢Dry contact 3
When the dry contact 3 connect to the DRY CONTACT of C12, it will control the output of C12. If the
system is turned off，the output of C12 will be closed via Dry contact3. If the system is turned on
and SOC ≥5% (5%~50% can be set), the output of C12 will be turned on via Dry Contact3, SOC≤
0% (0%~45% can be set, SOC of the C12 output is turned on≥SOC of the C12 output is turned off
+5%) , the output of C12 will be turned off via Dry Contact3.
4) Regular inspections
In order for the BMS to calculate the SOC of lithium battery more accurately and eliminate the
cumulative error of SOC, it is recommended to complete a full discharge (discharge to 0% SOC)
and a full charge (charge to 100% SOC) every 3 months.

Energy Hub User Manual

5) Charge Only function
Switch on MEH to O, when the system is turned off, the lithium battery can be charged by the
Alternator /Solar / Grid. The system only allows charging and prohibits discharging. The system
switches off the inverter and DC load via Dry Contact2 and Dry Contact3. Features as below:
➢When the Alternator input voltage meets the operating conditions of the internal booster
charger, the internal booster charger turns on the charging output, charging activates the
wake-up system and charges the Hub. When charging to SOC 100%, the system will stop
charging and turn off the lithium battery, and the system will all automatically power down.
➢When the Solar input voltage meets the Solar Mate operating conditions, the Solar Mate is
powered up to detect the status of the battery side：
a) When the system is switched off and other charging sources are not working, the Solar
Mate has to wait 5min before the output starts, the charging activation wakes up the system
and charges the Hub; if the Solar is underpowered, the first time causes the Solar Mate
output to be pulled down, the second and subsequent times the Solar Mate has to wait
another 20min before the output can be switched on again to start the system.
b) When other charging sources are charging the Hub, the SP starts outputting to charge the
Hub after 30s of power-up self-test.
➢When the Grid meets the CM operating conditions, the CM will turn on the charge output after
30s of power-up self-test, charge activation wakes up the system and charges the Hub.
6) Use the Hub in a low temperature environment
➢When the cell temperature is ≤2℃, the user cannot directly charge the Hub. In the low
temperature environment, when the internal charger is turned on, the Hub will automatically
turn on the heating function. After the built-in lithium battery is heated to 5℃, the Hub can be
charged normally.
➢When the ambient temperature is lower than -20°C, the Hub cannot be discharged and a low
temperature fault alarm will be reported. The user can via the internal charger to heat the
built-in battery before starting to discharge it.
➢At low temperatures, the battery discharge capacity decays by 10% to 30%. The lower the am
bient temperature, the more the discharging capacity decays.

6. Storage and Transportation
Storage
Please follow the storage instructions in this manual to increase the service life of the lithium battery
during storage. If you do not follow the storage instructions in this chapter for storage, the lithium
battery may be over-discharged and damaged. If the inspection reveals that the lithium battery is
damaged, please do not try to charge or use it.
Environmental conditions for storage: Keep away from water, dust and pollution sources, with good
ventilation The self-discharge rate of lithium battery during storage is less than 3% per month.
Be sure to store it in the power OFF state!
Note:
➢Before storing the lithium battery, please charge the battery to 100% SOC.
➢Please disconnect all loads and chargers connected to the Energy Hub.
➢Please turn the rocker switch to the OFF position to turn off the system.
➢Every 3 months, please charge the battery to 100% SOC; after charging is completed, please
turn off the lithium battery.
Transportation
The product has a built-in lithium battery. Before transporting lithium batteries, please check all local,
national and international applicable laws and regulations.
