Hello, I hope someone can help / point me into the correct direction. This is a ESS system which is running in the UK. Grid code is set to G99 ESS Assistant installed on both units This morning I noticed that the multiplus’s were discharging at around 4400w, even though the load exceeded this and it was pulling a considerable amount from the grid on top, around 2000w. The two multipluses should be able to provide the power no problem and have till this point. I have tried restarting everything, however this didnt change anything. Multiplus’s are running version V552 - Master Unit HQ23156EGX3, Parallel Unit HQ2207HVRTM. I have 2x Seplos mason batteries proving 28.8kW of storage. I have provided a screenshot as an example. ![Screenshot 2024-09-27 at 09.54.33](https://europe1.discourse-cdn.com/victron/original/2X/4/4ec873ae61f4ae21c4e136d9532b508d6499f4ab.png) ---

Long Shot have you got DESS enabbled? ---

No, I don’t. I have some node red running which makes sure I export at maximum. But that doesn’t kick in till the battery SOC is at 95% ---

You gone through your Nodes? and have you got a switch on the node so that you can return the multiplus to normal and then disable them and go from there? ---

Hi! It sounds like there may be a configuration issue or a fault with the multiplus units. Check the settings for load sharing and ensure that both units are properly communicating; consider reaching out to the manufacturer for further diagnostics if the problem persists. ---

I’ve disabled the node red stuff at the moment just to remove that element from fault finding. ---

How are you metering the grid side and PV inverter? ---

Are you using grid meter (ET112 or VM-3P75CT)? Or are you using CT clip to measure the grid? ---

So the grid is being monitored by a ET112 and the solar is being monitored by Modbus. The DC solar is just charge controllers directly connected with ve direct cables. ---

Where would I find load sharing settings? ---

Small update - I shortened the USB for the ET112 to 20cm just to make sure this wasn’t the issue. No difference. I tried downgrading the code on the cerbo to v3.32 The other thing that I have noticed it seems to behave like this when exporting too. So when there is plenty of sun it’s charging the battery but also dumping about 10% to the grid. ![IMG_9588](https://europe1.discourse-cdn.com/victron/original/2X/a/a702c1992e1ab5a9ef98425fe671e5a2f6d5a519.png) ---

Morning, I have narrowed the issue down. This excessive grid use is only apparent when I have ACOut1 connected. Removing this connection on both inverters sorts the issue out completely. Now I am stumped, any ideas? ![IMG_9624](https://europe1.discourse-cdn.com/victron/original/2X/a/a782590c7f97a4bbfffad8f9f16e8ec88080ec6c.png) ---

Now I have narrowed the issue down, I will open a new thread.
