Communication between inverter and battery
The communication between meter and inverter is an RJ45 interface cable. A 3M length battery communication cable is already
attached to the inverter when you received it, and you just need to insert it to the BMS interface of the inverter and Sub-Master
BMS.
1) The EMS communication between inverter and battery should be connected through the RJ45 cable that is attached to the
inverter when you need to control the work of the hybrid inverter.
2) M-TEC 10kW hybrid inverter integrated a set of relay output dry contacts with the contact capacity 230Vac/1A or 30Vdc/1A
that are very useful in some special circumstances, such as in the purely off-grid system, it can be used to trigger the backup
generator. Please contact your installer or M-TEC service team to learn more detailed operation steps.
Multiple inverters parallel connection/EMS/Relay output dry contact
Multiple inverters parallel connection, EMS and relay output dry contact interfaces use the 6pin terminal on the right side, and you
can use the matching 6pin terminal in the accessory box to make the connection.
