Damage to the inverter due to moisture and dust intrusion
If the ESS is not plugged in or incorrectly plugged in during operation, moisture and dust can
penetrate the inverter. If the ESS is not correctly plugged in, this can cause contacts in the ESS to
wear or the ESS might fall out of the socket. This can result in yield loss and damage to the ESS.
Always plug in the ESS as follows:
• Firmly plug in the ESS until it is flush with the
enclosure.
• Ensure that the gap between the ESS and the
enclosure is no more than 1 mm.
