Solar, Battery and Inverter Compatibility
Know what to verify before pairing solar panels, a lithium battery and an inverter: electrical limits, BMS communication and real load requirements.
Start with exact models and the intended use
A solar system should be assessed as a complete system. Battery capacity, panel wattage and inverter power each describe only part of it. Before buying or replacing equipment in Lebanon, collect the exact model numbers and describe which appliances must operate together and the backup time you want.
Check electrical limits and load requirements
Compare the inverter’s battery-voltage range and charging capabilities with the battery’s documented limits. Check continuous output and the duration of peak power against the intended loads. Specifications can vary with conditions such as temperature. A shared nominal voltage or a large power figure alone does not establish a suitable match.

Confirm the BMS communication requirements
Some lithium battery systems communicate with the inverter or a system controller through a supported BMS protocol. Check the current manufacturer compatibility guidance for the exact combination, including any required controller, cable and software version. A connector labelled CAN does not by itself confirm protocol compatibility. Electrical compatibility and working communication should both be established where the system requires them.

For Deye systems, check the specific battery combination
Deye publishes approved battery lists for specified inverter families, with battery models and communication requirements. Check the current list relevant to the proposed inverter and confirm the combination with the battery supplier. This is model-specific guidance, not evidence that any battery bearing the same voltage or a CAN socket is approved.

Solar input has its own limits
The solar array must suit the inverter’s or charge controller’s PV input. Check allowable voltage and current, the MPPT operating range and array open-circuit voltage. Panel wattage alone does not establish compatibility. Use the actual panel and controller documents and the proposed system design.
