Does this have function to discharge to grid from battery?

[alengcm]

I currently use a 'selenium' automation to achieve this.

I can controll a Growatt SPA3000 with various commants. To discharge to the grid i use the following command from a raspberry Pi. Written down in a .py file

import growattServer import sys import json ''' Sample script to set AC battery discharging Takes commandline arguments for terminal SOC, start time, end time, and whether to run, with default arguments if none are given Tested on an SPA3000 '''

check for SOC percent and whether to run

if len(sys.argv) != 7: SOC = '40' startH = '0' startM = '40' endH = '04' endM = '30' run = '1' else:else: SOC = str(sys.argv[1]) startH = '{:02.0f}'.format(int(sys.argv[2])) startM = '{:02.0f}'.format(int(sys.argv[3])) endH = '{:02.0f}'.format(int(sys.argv[4])) endM = '{:02.0f}'.format(int(sys.argv[5])) run = str(sys.argv[6])

This part needs to be adapted by the user

api = growattServer.GrowattApi(False,"Login") api.server_url = 'https://server.growatt.com/'

This part needs to be adapted by the user

login_response = api.login('Login', 'Pasword')

if login_response['success']:

Get a list of growatt plants.

plant_list = api.plant_list(login_response['user']['id'])
plant = plant_list['data'][0]plant = plant_list['data'][0]
plant_id = plant['plantId']
plant_info = api.plant_info(plant_id)
device = plant_info['deviceList'][0]
device_sn = device['deviceSn']

# All parameters need to be given, including zeros
# All parameters must be strings
schedule_settings = ['20',          # Discharging power %
                     SOC,            # Stop Discharging at SoC %
                     startH, startM, # Schedule 1 - Start time
                     endH, endM,     # Schedule 1 - End time
                     run,            # Schedule 1 - Enabled/Disabled (1 = Enabled)
                     '00','00',      # Schedule 2 - Start time
                     '00','00',      # Schedule 2 - End time
                     '0',            # Schedule 2 - Enabled/Disabled (1 = Enabled)
                     '00','00',      # Schedule 3 - Start time
                     '0']            # Schedule 3 - Enabled/Disabled (1 = Enabled)

response = api.update_ac_inverter_setting(device_sn,
                                          'spa_ac_discharge_time_period',
                                          schedule_settings)

else: response = login_response print(json.dumps(response))

I found this scipt on a other side and made it work for my system.

Nice. I will try that.
