Solar Assistant Monitoring Kit | Sunsynk Deye Raspberry Pi 4

Monitor your hybrid inverter setup in real time with this ready-to-use Solar Assistant kit, built around a Raspberry Pi 4. It works with Sunsynk, Deye, Sol-Ark and Fusion Hybrid inverters, showing PV generation, battery state of charge, grid import/export and load consumption in a browser or app based dashboard. No subscription fees, no manual setup.

Key features

• Pre-loaded hardware, Raspberry Pi 4 Model B (2GB RAM, 1.8GHz quad-core CPU) with Solar Assistant software already installed
• Storage, 32GB Lexar Micro SD card included
• Power supply, official Raspberry Pi USB-C 5V power supply included
• Inverter connection, RJ45 to USB RS485 communication cable
• Enclosure, pre-configured plastic case with cooling fan and full port access
• Access, remote monitoring via web browser, Android or iPhone app

Product overview

The kit arrives fully assembled and pre-configured, so there is no software installation or system setup to do. Connect it, power it on, and the dashboard starts showing your inverter data with dynamic charts.

Communication runs through the inverter's RS485 port using the included RJ45 to USB cable. That port needs to be free before you install the kit. If RS232 or Wi-Fi is already in use on your inverter, RS485 is the alternative route in. Parallel or three phase systems need one cable per inverter.

An optional RJ45 splitter is sold separately for Deye, Sunsynk and Sol-Ark owners who need to share the BMS port between battery communication and the Solar Assistant cable. It separates the CAN and RS485 lines so the two signals do not conflict.

Compatible inverters

• Sunsynk
• Deye
• Sol-Ark
• Fusion Hybrid

What's in the box

• Raspberry Pi 4 Model B (2GB RAM) in a pre-configured enclosure with cooling fan

Installation notes

Check that your inverter's RS485 port is free before ordering. The communication connection itself carries no mains voltage, but the inverter must still be installed and serviced only by a qualified electrician or solar installer. Do not open or modify the Raspberry Pi enclosure while it is running.
