Non-nominal systems:

– Generator :
The generator worked properly during the night. It had a low battery failure at about 5am, which is normal since we charged the battery for only two hours yesterday. We keep going with the idea of charging the battery during the day to run the generator during the night. We started charging the battery at 8:40am. At 4:50pm, the charge of the battery was 75% while the SOC was 89%. We thus decided to connect the battery to the generator and it is working properly since then. At 7:20pm, the charge of the battery is still 12V.
