As per the issue you referenced, this is nothing to do with the Huawei intergration or the 'Grid-Connected, Grid connection with derating due to power rationing' status. That message is due to issues with your Utility Network Provider (voltages etc) and/or the 'Grid Code' that you have set. There should be a grid code specific to your country and/or Utility Provider network, that MUST be used (don't try and fiddle the settings in the inverter or use the incorrect codes, this is illegal and could break your setup). First thing though, connect your second inverter to the first (that I assume has the DDSU-666H meter and LUNA battery attached to it?) that will be your primary inverter that controls the secondary / overall site. This is a simple 2 wire connection between the RS485A / B ports on the inverters, a run of Cat5A cable wire is fine to use, if you don't have any official RS485 wire. One simple thing to do is go to Settings --> Actions --> and select "Huawei Solar: Set Active Power Control to Maximum Feed Grid Power" then choose the primary inverter and select 'Perform Action'. That shouold tell the inverter to export the max to the grid, your battery should have its settings that also determine what energy goes to it first. If your utility provider has a limit on how may kW you can export, then use 'Huawei Solar: Limit the power fed to the grid' and enter the Watts instead. |

Thank you for your help. I didn't install the system, so don't have an installer account on FusionSolar. The second inverter is connected to the first one and everything appeared to be working correctly when the installers left. I setup the plugin for HomeAssistant a couple of days after they left, but only had 1 WiFi card so could only connect to one of the inverters from HA. I'm assuming that I need to connect to the other inverter as well to get all the electricity generation figures as what I'm seeing in HA doesn't match FusionSolar. It was at this point I noticed that energy wasn't going back to the grid, so is probably coincidental. I will check to see what settings I can change in FusionSolar and respond with more details. |

If your connecting via the sDongle, plugged into the primary inverter, then the RS485 cable to the other inverter will provide the communications for ALL the inverters/battery/meter. You need the installer account to get this running correctly. It's your property ask/tell the person who installed that you require it. edit: the L1 has a built in wifi ap from memory, don't use it, use the aDongle. If you try to plug a dongle into each inverter it will also stuff up. 1 only. |

When I tried to connect to the system from HA, I only saw the WiFi for the 2 inverters, so connected to the primary inverter. The system has a dongle, but I didn't see the WiFi ssid for that. Should the dongle have its own WiFi, and should I connect directly to that, or should I be getting all the info from the primary inverter? Sorry if It's a stupid question but the whole Solar stuff is new to me. I'm currently away for the weekend, and trying to set this up remotely, I may have to wait until I get back next week to set it up properly. |

Your connecting to the inbuilt WiFi of the inverter, if you have the sDongle you don't connect to it. You use the SolarFusion app (the one on a mobile device, not the website portal) to configure the inverter/devices, including setting up the dongle and telling IT to connect to your home WiFi network. |

Thanks so much for your help. I'm back home early next week and will see what I can sort out. I did ask the installer to open O&M access to the system, but they didn't know what I meant. If they haven't changed the password, do you know if I can connect to the system with my own installer account without blocking the company from their access? It looks like this definitely isn't a bug, would you like me to close this ticket and comment afterwards with any information that may be useful for other users? I |

Describe the issue
This issue is similar to https://githubissues.com/wlcrs/huawei_solar/714, however my connection is via a WiFi card in the raspberry pi where HA runs, to the inverter.
Since installing this plugin, I am no longer able to export any electricity to the grid. My battery is working as expected, but the inverter seems to stop generating excess electricity and sending it to the grid.
Is there any way of fixing this, either in the FusionSolar app,or within Home Assistant, as this is now a major problem.
I haven't changed the configuration of the system from Home Assistant, my main goal was to control equipment depending on the output of the panels.
I have 2 inverters, a dongle a battery and a backup system. I'm currently only connected to one of the inverters, but was planning on creating a bridge to the other once the system is working correctly.
