Growatt SPF ES5000 inverter + Dyness BX51100 lithium battery + 10 x 380 Watt perc mono solar panels

I have just installed the above setup. It all works fine in the day with solar but stops working at about 1:00 AM every morning. It seems that the grid does not kick in when the battery runs low.

Has anyone connected the BMS communication for this configuration? When I set the code 05 on the inverter to 'LI' and the code 36 to protocol to L01 I get an 04 error code. The battery is charged to above 75%. I have setup the correct DIP switch for the inverter. (for RS485)

I am currently using the 'USE' setting on code 05 and I have set the appropriate dyness settings on the inverter (From the dyness manual). Inverter codes 12, 13, 19 and 20.)

 

Any help will be greatly appreciated.

Thanks very much @Buyeye.

The DIP switch setting specifically states RS485

It states: 'If the battery communicates with the Growatt SPF ES by RS485 communication turn the master switch "#2" and "#3" to "On"'

With this in mind should I still use the CAN port and protocol 52 with that DIP switch setting?

Please would you send me the link to the Video you mentioned

Thank you Dyness. Should the DIP settings on the battery all be off and the cable connect to the Growatt inverter via the 'BMS port' . The code on the inverter will be set to 05 - LI and code 36 - L52. This is for CAN and not RS485, is this correct?

I get the 04 error when the DIP has pin 2 and pin 3 "ON" (according to the manual) and I connect to the Growatt inverter on the "485 port". The code on the inverter is set to 05 - LI and code 36 - L01 (RS485)

 

I am so sorry for the basic questions. My installer is just not getting it right, and is not responding to my requests for assistance.

Many Thanks

GarthW

Sorry for the late response.

I am not sure if the settings are the same.

Are you setting code 05 on the Inverter to 'USE' or 'LI'?

If 'USE" then the battery manual will give you the parameter settings for the inverter.

If 'LI' then I can send the settings for the BMS connection I am using.

I am going back to the 'USE' setting as the battery is not charging correctly with 'LI'

Hi

Would you be able to share your BMS settings as I can't get my growatt ES inverter to communicate with my dyness 5.1kw battery for some reason?

Got it connected and working. For some reason the newer firmware version Growatt SPF5000ES does not show CAN or 485 under the battery setting options.

Just set to battery "LI" then change to L52 and done, using the CAN port. Dip switch 3 to ON.

Good day, my growatt spf5000es does not show a L52 when setting it to LI. Goes back to AGM .

Probably because no Li BMS comms exist.
Are we to assume you have the same battery as the original poster from 2 years ago?
How did you do your Inverter to Battery comms connection?

I have the dynes bx51100 batteries connected in parralel, the comms is correctly configured... i have managed to get it working by changing the master dipswitch to 3 and not like the booklet states as 3&4. Slave battery should all be 0.

Every night now from midnight it charges by importing from the grid untill 04h00, should this be neccesary? What percentage can i let the batteries go down to without damaging them as I would actually like to charge by solar only as set on the inverter on menu 14, but it still imports from grid

Hi I used to have the 5000es paired with the 10kwh powerbox. The issue was not the depth of discharge, you can set that to whatever is recommended. The issue was top balancing. The bms is forcing grid charging to protect the cells that go below the threshold. To prevent that battery needs enough charging source when it is almost full to ensure all the cells are as close as possible.
