Introduction<\/h2>\n\n
Deye, Sunsynk and Sol-Ark inverters can be connected to the Qilowatt system using a Modbus module. This guide explains the necessary settings, wiring connections, and how to start the module. <\/div>\n\n

Prerequisites<\/h2>\n\n
\u2022 A technician has verified that the inverter is operating correctly\u2022 The inverter is able to charge batteries from the grid and, if permitted, sell energy back to the grid\u2022 Battery maximum power limits are taken into account\u2022 A Modbus R1 or R2 module is available\u2022 Required tools and a communication cable (CAT5 or CAT6)<\/div>\n\n

Step-by-step Guide<\/h2>\n\n

Inverter settings<\/h3>\n\n
1. <\/strong>Open Deye inverter menu.2.<\/strong> Configure the following settings:\u2022 Modbus SN (address):<\/strong> 01\u2022 Master\/Slave:<\/strong> Slave\u2022 Modbus baudrate:<\/strong> 9600\u2022 Time of Use:<\/strong> activated<\/div>\n\n

Installing the module<\/h3>\n\n
1.<\/strong> Install the MODBUS module<\/strong> according to the installation manual.2.<\/strong> Connect the communication cable (CAT5 or CAT6) from the module\u2019s RS485 A and B terminals to the corresponding inverter port.\u26a0\ufe0f Important!<\/strong>\u2022 <\/strong>If the inverter mainboard has a DRM port<\/strong>:Connect the MODBUS R2 module terminals A and B to the inverter BMS port<\/strong> pins:\u2022 <\/strong>Pin 1 \u2192 B+\u2022 <\/strong>Pin 2 \u2192 A-If the BMS port is already in use by the battery, use the Y-splitter <\/strong>included in the installation kit.\u2022 <\/strong>If the inverter does not have a DRM<\/strong> port:Connect the MODBUS R2 module terminals A and B to the inverter Modbus port<\/strong> pins:\u2022 <\/strong>Pin 7 \u2192 A-\u2022 <\/strong>Pin 8 \u2192 B+<\/div>\n\n
\"\"<\/div>\n\n

Starting the module<\/h3>\n\n
1. <\/strong>Switch on the circuit breaker of the MODBUS R1 \/ R2 module (or insert the fuse).2.<\/strong> Check if the module\u2019s white LED indicator<\/strong> starts flashing rapidly.3.<\/strong> Connect the module to your home WiFi network \u2192 Connecting the device to WiFi.<\/a>4.<\/strong> Place the module in a location with a strong WiFi signal.5. <\/strong>If needed, use a WiFi range extender.<\/div>\n\n

Result<\/h2>\n\n
The inverter is successfully connected to the Qilowatt system. The Modbus module transmits data and enables device control and optimization. <\/div>\n\n

If it Doesn’t Work<\/h2>\n\n
\u2022 If the LED indicator does not light up, check the connections and circuit protection.\u2022 If communication does not work, verify that the Modbus address and baudrate are set correctly.\u2022 If the module does not connect to WiFi, follow the guide \u2192 Resetting WiFi settings<\/a>\u2022 If the issue persists, contact our team: support@qilowatt.eu<\/a>. <\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":288,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_gspb_post_css":"#gspb_heading-id-gsbp-54d638e,#gspb_heading-id-gsbp-b1f36d1{font-size:var(--wp--preset--font-size--medium)!important}.gspb_text-id-gsbp-26d610d,.gspb_text-id-gsbp-9e5501d{margin-top:0!important}#gspb_heading-id-gsbp-b1f36d1{margin-top:20px}#gspb_heading-id-gsbp-43464ca{font-size:var(--wp--preset--font-size--medium)!important;margin-top:20px;margin-bottom:0}.gspb_text-id-gsbp-0606274,.gspb_text-id-gsbp-832a9ec,.gspb_text-id-gsbp-9a54607{margin-bottom:0!important}#gspb_heading-id-gsbp-19e1e31,#gspb_heading-id-gsbp-9106fc8{font-size:18px;margin-top:20px;margin-bottom:10px}#gspb_image-id-gsbp-06837e0 img{vertical-align:top;display:inline-block;box-sizing:border-box;max-width:100%;height:auto}#gspb_image-id-gsbp-06837e0{margin-top:20px}#gspb_heading-id-gsbp-ead0a41{font-size:18px;margin-top:20px;margin-bottom:10px}#gspb_heading-id-gsbp-a223463,#gspb_heading-id-gsbp-fed8eac{font-size:var(--wp--preset--font-size--medium)!important;margin-top:20px;margin-bottom:0}","footnotes":""},"doc_category":[190,145],"doc_tag":[147,139,146,126,149,148],"class_list":["post-338","docs","type-docs","status-publish","has-post-thumbnail","hentry","doc_category-3-inverter-installation-pick-the-right-one","doc_category-inverter-installation","doc_tag-deye","doc_tag-installation","doc_tag-inverter","doc_tag-modbus-r2","doc_tag-sol-ark","doc_tag-sunsynk"],"blocksy_meta":[],"year_month":"2026-04","word_count":355,"total_views":0,"reactions":{"happy":0,"normal":0,"sad":0},"author_info":{"name":"marko","author_nicename":"marko","author_url":"https:\/\/docs.qilowatt.eu\/en\/author\/marko\/"},"doc_category_info":[{"term_name":"3.
