Operation

1. Use MEH to turn on/off the system

The rocker switch on the MEH can be used to turn the system on and off.
Press I to turn on, and press O to turn off.
Note: After the switch is turned on, the Run, ALM, and SOC lights will flash in turn. After about 8s, the system will have DC output and MEH will start to work.

D+ function

When the vehicle is fitted with a smart alternator, please connect the D+ to the alternator control signal or ignition signal, otherwise, the charger works in the traditional alternator mode.

D+ signal control logic

Generator Type| D+ signal status| Starting battery voltage conditions| Working Status
---|---|---|---
Smart
Generators| With D+ signal| Start battery voltage ?- 12V (default)
(12-14.5V can be set)
Working range: 12-16V(default)| Running
Start battery voltage C (default)
(11.6-13.5V can be set)| Stop operation
No D+ signal| Irrelevant| Stop operation
Traditional
Generators| No D+ signal| Start battery voltage ?- 13.2V (default)
(12-14.5V can be set)
Working range: 13.2-16V(default)| Running
Start battery voltage C 12.8V (default)
(11.6-13.5V can be set)| Stop operation

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 C interface 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 connects to the remote of the 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 the inverter is turned on≥the SOC of the inverter is turned off +5%), the inverter will be turned off via Dry Contact2.
  

Dry contact 3
When the dry contact 3 connects 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.

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.

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 the 30s of the power-up self-test.

• When the Grid meets the CM operating conditions, the CM will turn on the charge output after the 30s of the power-up self-test, charge activation wakes up the system, and charges the Hub.

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 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 ambient temperature, the more the discharging capacity decays.

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.
