š” Use Cases / Ideal Applications
-
Hybrid solar + storage setups requiring inverter-battery communication
-
Mixed-brand installations (e.g. solar array from one brand, battery from another) needing a universal communication bridge
-
Backup power systems, off-grid installations, or grid-tied hybrid systems
-
Commercial, residential, or industrial energy storage systems needing reliable BMS-inverter data exchange
-
Retrofit projects where existing battery/inverter systems need a universal communication interface
š ļø Installation & Integration Notes
-
Connect module between battery BMS port and inverter communication bus (RS-485 or CAN)
-
Use correct protocol settings (baud rate, parity, address) as required by inverter and battery BMS
-
Ensure proper wiring and isolation ā twisted pair for RS-485 / CAN lines, correct termination at ends
-
Enable monitoring & control via inverter software or external monitoring platform for real-time data (SoC, charge/discharge status, fault alerts)
