Combining AC coupled storage
solutions with standard APsystems
Microinverter series
LEADING THE INDUSTRY
IN MLPE TECHNOLOGY
Storage systems are more and more popular worldwide. This paper provides generic
guidance on how standard APsystems microinverters can interface with most of AC
coupled storage systems.
• Standard APsystems microinverter in single or thre phase grid �ed systems.
• Storage system AC coupled only.
• Storage system has received all required cer�fica�ons for the country of installa�on.

Storage system without back-up :
If the storage system has total back-up func�on, microinverters must be turned off during grid shortage or installed separately
from other back up circuits that include an�-islanding relays. Without AC from grid, it will be a closed loop and can damage
equipment on rood and/or in home.
