Pylontech M1C-UL9540 User Manual page 79

Press and hold the Start Button for more than 5 seconds until the buzzer rings, the LED indicator on front
panel will light on if the start-up is successful.
NOTE: Do not keep pressing the start button more than
30 seconds, or it will go into "BLACK- START" mode.
System start process:
The battery string's system will check itself. If power on successfully the battery string system will enter self-
check mode automatically.
If the BMS and all battery modules are working normally, every status LED will be lighting green, that's mean
self-check are passed. Self-check will be finished within 10 seconds.
Black-start function:
If long press (>10 seconds) the start button 30 seconds AFTER power on. The "STATUS" lamp will become
green if the black start function is enabled. If "STATUS" lamp remains red, the black start function is failed to
active, it needs long press start button again. System will close relay and output for 10 minutes.
Warning: if the black-start function is enabled, the terminal of D+ and D- will be electricity
dangerous with high DC voltage output.
Les bornes D+ et D- présentent une tension de sortie en courant continu élevée et présentent un
risque de mise sous tension si la fonction de démarrage en noir d'activation est activée.
Caution: If the BMS can't receive communication from upper equipment because of the
communication is off, the "STATUS" lamp will light red after 30sec. That doesn't mean failure
existed, it means this battery string is OK while the external communication is off.
Attention: Si le BMS ne peut pas recevoir de communication de haut niveau parce que la
communication est hors service, La lampe «d'état» sera rouge après 30sec. Ça veut dire que la batterie est OK
pendant que la communication externe est coupée.
Warning: If there is failure during the self-check, must debug the failure then can start next step.
En cas d'échec lors de l'auto-contrôle, vous devez déboguer l'échec pour pouvoir commencer à
l'étape suivante.
If the "STATUS" lamp on BMS/battery shows red from beginning, it means there is some failure in
the battery string, the Power Relays in BMS will open, and it must be debugged at first.
Si le voyant "STATUS" est rouge depuis le début, cela signifie qu'il y a une défaillance de la chaîne de batterie,
les relais de puissance dans le BMS s'activent et il faut déboguer en premier.
NOTE: The LED lamp will be off in 20sec without any operation.
La lampe à LED sera éteinte dans 20 secondes sans aucune opération.
4. Turn on the external switches or breakers all after all the BMS turn on successful:
When the voltage distance is smaller than the parameter, the battery string will do the parallel operation.
Caution: The whole Battery Energy Storage System (BESS), after installation or restart the system
when long time not in using, should be charged to full at first.
Attention: Pour l'ensemble du système de stockage d'énergie de batterie (BESS) après
l'installation ou le redémarrage du système après une longue période d'inactivité, il faut le charger
complètement au début.
