Product Overview
This kit comes fully assembled and pre-configured, removing the need for manual software installation or system setup. The Solar Assistant platform displays all key metrics including PV generation, battery state of charge, grid import/export, and load consumption in an intuitive dashboard with dynamic charts.
Communication with the inverter is via the RS485 port using the included RJ45 to USB cable. The RS485 port on the inverter must be free before installation. If the RS232 or Wi-Fi ports are already in use, RS485 is the correct alternative. For parallel or three phase systems, one cable per inverter is required.
An optional RJ45 splitter is available separately for Deye, Sunsynk, and Sol-Ark users who need to share the BMS port between battery communication and the Solar Assistant cable. This splitter correctly separates the CAN and RS485 lines to prevent communication conflicts.

Installation and Safety Notes
