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.
