1x ECM-2900 (Master) + (2-6)x ECS-2900 (Slave) (Connector Type A)
1x ECM-2900 (Master) + (2-6)x ECS-2900 (Slave) (Connector Type B)
1x ECM-4100 (Master) + (2-6)x ECS-4100 (Slave)
1x ECM-4300 (Master) + (2-6)x ECS-4300 (Slave)
1x ECM-4800 (Master) + (2-6)x ECS-4800 (Slave)
This Inverter can have a MAXIMUM of 2 stacks with 7 modules per stack (1x Master + 6x Slaves), for a TOTAL of 2x Master + 12x Slaves.


IMPORTANT: installers shouldn’t use CT to achieve anti reflux function for MIC750-3300TL-X inverters. Instead they should use the single phase meter Growatt SPM.

Growatt has confirmed that although the use of CT is mentioned in the user manual, because issues have been found with this type of option, they decided to stop promoting CT for limitation to the grid altogether. Therefore, now they recommend the use of the Growatt SPM ONLY for that purpose.
