This is common fault in GB-L, a consequence of poor balancing strategy in BMS. You can charge the battery to 100%, disassemble the modules, measure ...
You count from the top down. First pack is always just below the BMS unit. Charge your battery to 100%, disassemble it and measure voltage of indi...
To my knowledge only XL02-B supports monitoring.
I guess this does not exist... fine then 🙂 Ask Deye support why are they unwilling to install this FW as a "standard issue".It is available for wee...
Update the firmware with the version that supports "smart devices". Then you will be able to select "SmartTX" under Meter Type. Then you will have...
Yes, there is a specific version of FW that enables module balancing.But it works in a peculiar way. It does not balance while the battery is sitting ...
Your modules are most likely unbalanced. That means the SOC of one module is higher or lower than SOC of other ones. Did you ever expand the batte...
1183 and C072 were "pulled back" by Deye, due to bugs reported by users. Especially C072 caused lithium protocol to change from 0 to 65535 by itself...
Time for a new control board... no other solution from my experience.
C072 HMI is the latest with LoRa support, and should be used with 1183 MAIN FW.
Yes you can use GB-L Pro BMS with "old" GB-L modules. No problem with that, no firmware update needed, fully compatible out of the box.
This is a well know problem for several months now. Deye has two different types of GB-L PRO battery blocks, with two different suppliers of LFP cel...
Ask Deye support staff to upload 4004 firmware to your BMU. That should fix the problem.
Your CTs are almost 100% positioned wrong. You can see that by the fact the inverter measures very high reactive power over 1000VAr on all three pha...
You cannot expand GB-L "non-pro" with GB-L pro modules. They are not compatible, GB-L pro uses different cell chemistry. Combining non-pro with pro ...
