Battery-free operation function makes solar system less costly to build. Use solar panel to supply power directly to the load in good light conditions to complement utility power. Use RS232/RS485 to manage with BMS of lithium battery through Modbus or CAN communication protocol to make the system run more stable and to protect the lithium battery safely to make its life longer. Support WIFI or 4G to realize cell phone APP to monitor the system.
