Translation first post:
Maybe my information will help someone:
- Today, 05/24/2025, Deye support updated the firmware for me via the Internet
- SUN-12K-SG04LP3-EU
to the firmware version
- MAIN: 2005-1172-1807
- HMI: 1001-C050.
It works stably.
- Non-critical remark: Auto Dim works. The value of Sleep Time = 10 min is fixed, but without the ability to change the timer
- Positives:
-- before that: according to the previously provided information from Deye support (DeyeApprovedBatterylist(DY-LV48-0093).pdf), GOOTU batteries based on BMS - DAREN - are not in the Approved Battery list. and I was forced to work with batteries in Mode- Battery Volt - there was no possibility to connect the BMS normally.
-- after update: successfully connected "two GOOTU batteries based on BMS - DAREN" to my Deye inverter.
Connection parameters:
- On the inverter: BMS/CAN pinout standard for JS485 (1-8), Batt Mode: Lethium; Lithium Mode: 00
- On the master side - "GOOTU battery based on BMS - DAREN" model: "JSL-WB48300": CAN pinout standard for JS485 (1-8)
The batteries are connected in parallel, communicate well with each other: Master - Slave
Translation second post:
I solved this problem, now the next one: how to connect GBL2.45.K3 batteries to another GOOTU inverter via CAN BMS
How to configure the GOOTU inverter to connect a GBL2.45.K3 battery via the AoBo CAN protocol?
For this
- I am looking for technical documentation on the AoBo CAN protocol: ID frame, decoding of packages, especially examples
I would be very grateful if someone could help with this

My guess is you use translation with this site. Please make sure you paste the English version back instead of the Ukrainian one, it's easier to follow the conversation this way without having to translate individual posts.
