9.3.3 5K3XP WECO BATTERY START-UP
In order to carry out the correct start-up procedure:
1. The HV-BOX must be switched off;
2. The batteries must all be switched off (side switch to 0);
3. Inverter DC rotary switch set to OFF;
4. Set all batteries via side switch to 1 without switching them on (
do not
press round metal
button);
5. Switch on the HV BOX via its switch;
6. The batteries will automatically switch on in succession (each module will turn on independently
and the side switch will flash for 3 seconds; after which, a steady GREEN light will confirm that each
module is powered on);
7.
The HV BOX will end the start-up procedure within 90 seconds by closing the input circuit (the
RED and GREEN lights will turn on to confirm its operation);
NOTE:
If communication between the inverter and the HV BOX is lost for more than 60 seconds
during or after the start-up phase, the HV BOX will enable the safety procedure by opening the
POWER CONTACTOR. During the commissioning phase, the installer must ensure that the
communication between the HV BOX and the inverter is connected properly. Do not leave the
system powered when there is no communication between the HV BOX and the inverter, as
prolonged standby of the system could cause an imbalance due to natural self-discharge.
