Issue integrating Deye RW-F16 battery with Victron MultiPlus-II GX

Hi everyone,

I’ve recently installed a Deye RW-F16 (16 kWh, LiFePO4) battery connected via CAN to a Victron Energy system with a MultiPlus-II GX inverter.

Although everything seems wired correctly, I’m facing two issues:

  1. The inverter displays energy flow in reverse — when the battery is charging, it shows as discharging, and vice versa.
  2. The battery won’t charge beyond 80% SOC, even though it should go up to 100%.

Has anyone experienced these issues with Deye batteries in a Victron setup?

I’d appreciate any advice or solution to ensure the CAN communication is properly interpreted by the Victron system.

Thanks in advance!

It is an unsupported battery, and if you do a search you will find another topic like it.
Deye need to make sure their comms meet the Victron spec, but as it is unsupported, you will have to rely on other users who have had the learning curve aleady. It isn’t something Victron are likely to assist with.
