It would have been very helpful if one could have access to the complete installation layout instead of addressing it piecemeal.

I would recommend changing a couple of settings:

Tick ' Zero export to CT'. This allows the hybrid function of the inverter to power the 'Non-essentials' as well.

compared to your current setting of 'Zero export to load'

On one of the screens above the power inflow and out from from the inverter doesn't match. Around 2.05kW PV, but almost nothing from battery, but then 0.98kW going to loads and 2.68kW exported to grid. Was this transient? Any chance there's a problem with the CT coil fitment?

Are you intentionally selling to the grid?

I would reconsider the percentages in the different time slots and activate grid charge options. If the battery DOD reaches 80% by 17:00, the Inverter will automatically switch to Grid power untill 05:00. But you'll know best what your requirements are.

The inverter will always prioritize using PV to charge the batteries.

The 'low battery' and 'restart' values will trigger a continuous alarm signal. Change the value of the restart upwards.

Thanks,will do.

No. Ever since the parallel installation, the inverter sells to the grid and also draws from the grid when it should be drawing from the batteries. Batteries are never being used no matter what settings I change in Time of Use. The batteries are only used when there is no municipal power.

Also, the system will not produce any PV if I don't tick "Solar Sell".

Check the wiring of the CT. It may have been swapped. You can rearrange it and see if the feedback to the grid stops.

That is correct. See this description.

Could it be possible that your loads are all connected to the grid-port(s) of the inverter? That could be one explanation why you are not ever diverting battery power to the loads, but if you use Solar-Sell it could be that your exports are being channelled to the grid-side loads.

As above, try changing your setting to "Zero Export to CT" and then un-ticking the Solar Sell box, and then see what's happening. Sorry for the repetition.

Thanks for the suggestion. This is what I’m getting after unticking solar sell and selecting”Zero Export to CT”.

Keep the 'Solar sell' option selected

I can just share my settings that work for no export to grid. On the system mode page tick only Zero export to CT. All other blocks blank. Make the solar sell value zero. Keep the always draw from grid at 50W.

My thanks to @GreenFields for helping me out when my Deye exported to grid when I installed it.

Respectfully, I disagree. Don't tick Solar Sell if you are not normally exporting power to the grid. Especially if you don't have a registered system.

I don't see anything obviously wrong in the settings that explains why the battery is not supplying the loads when it should. Try to eliminate everything else first. Turn of the Main Switch on the DB board, and if it's daytime, turn off the PV knobs on the underside of the inverter. It will then be operating like a UPS, disregarding any time-of-use settings, and also disregarding your CT coil. Does the battery then begin taking over carrying the loads on the backup load port, like it would in the event of an emergency or power outage? Or do you find yourself sitting in darkness?

Hi, thanks, I see your point. I've found that the description of foreign-developed UI's can sometimes be somewhat misleading.

However, if one interprets the description in the manual, it explains that the 'Solar sell' option is not only relevant to the grid export function, but also necessary for the 'Zero export to load' and 'Zero export to CT'. It influences the flow logic (in combination with other settings). It should be active in both options.

See the dependencies between the different workflow options in the clip below:

Hi Greenfields, you are correct. The activations of the Solar Sell buttons add the selling option to the workflow.

Thanks

Hi All

Thank you very much for all the suggestions and advice. After having 3 different installers look at the system, we decided to split the inverters and run them individually. Everything now works perfectly with the caveat being that my batteries and panels are now split.

Nonetheless, I truly appreciate everyone's input and time.
