SP2000 Storage Unit

[tonyemon]

Hello

I have enjoyed getting the Grott project installed on a raspberry pi and am getting some results from the SP2000 and shine datalogger. The correct Seriel numbers are being recognized and data is being forwarded to the growatt server but the default settings are not pulling out any battery information.

Is it possible to get this working, so that the battery records are pulled in as well. The SP2000 is installed between the PV Array and my Inverter to manage the DC electricity flows between Inverter and battery.

I have tried changing the Inverter Type to SPA but it then fails to recognise the sereil number and list no data on the Journalctl output, but the records are still being forwarded to the Growatt servers.

Please could someone advise if anything can be done.

Thanks

Hi

I have been looking through the threads and managed to guess a record layout that works for the SP2000 storage unit as per listing below. I have coded this into my local grottconf.py file and it pulls out the data I need.

self.recorddict3 = {"T06NNNN": {
"decrypt" : {"value" :"True"},
"datalogserial" : {"value" :16, "length" : 10, "type" : "text","incl" : "yes"},
"pvserial" : {"value" :76, "length" : 10, "type" : "text"},
"date" : {"value" :136, "divide" : 10},
"recortype1" : {"value" :150, "length" : 2, "type" : "num","incl" : "no"},
"recortype2" : {"value" :154, "length" : 2, "type" : "num","incl" : "no"},
"Generation_status" : {"value" :158, "length" : 2, "type" : "num"},
"pvpowerin" : {"value" :162, "length" : 4, "type" : "num", "divide" : 10,"incl" : "yes"},

"Solar Generation" : {"value" :178, "length" : 4, "type" : "num", "divide" : 10,"incl" : "yes"},
"bat_Volt" : {"value" :206, "length" : 2, "type" : "num", "divide" : 10,"incl" : "yes"},
"Battery_Charge" : {"value" :218, "length" : 2, "type" : "num", "divide" : 10,"incl" : "yes"},
"Grid_AC_Voltage" : {"value" :226, "length" : 2, "type" : "num", "divide" : 10,"incl" : "yes"},
"Import_From_Grid" : {"value" :238, "length" : 2, "type" : "num", "divide" : 10,"incl" : "yes"},
"Temperature" : {"value" :242, "length" : 2, "type" : "num", "divide" : 10,"incl" : "yes"},
"export_to_Grid" : {"value" :250, "length" : 2, "type" : "num", "divide" : 10,"incl" : "yes"},
"test_Bat_dischg" : {"value" :346, "length" : 2, "type" : "num", "divide" : 10,"incl" : "yes"},
"Solar_today" : {"value" :358, "length" : 4, "type" : "num", "divide" : 10,"incl" : "yes"},
"Solar_total" : {"value" :366, "length" : 4, "type" : "num", "divide" : 10,"incl" : "yes"}

Many thanks for this great program and my call/question can now be closed.

Regards

Tony

@johanmeijer is it possible to add this configuration to the master version? It could be useful for everyone having an SP2000 storage converter model
thanks a lot

Hello Johan....please feel free to update your master version. Regards

[johanmeijer]

Thanks. I will add this. Do you have a original data record for me so I can test it?

I tried also adding custom JSON in the config folder but without success
