UK Grid Export Limiting Device for Powerwall with Gateway and Solars

[NikoV6]

Hi, we have a Powerwall and backup Gateway 2. This is set to not export to the grid. If we were to add solar panels (10Kw) to the gateway would they also be effectively prevented from exporting to the grid?

I'm not in the UK but would expect this to be a gateway-wide setting as panels are generally "dumb". IOW, adding more panels should not affect the setting.

Once the battery is full. It would then start exporting to the grid. As the energy from the solar panels would need somewhere to go.

Sound like you are prevented from sending power from the Powerwall to the grid because of lack of solar. If it is like most setups here in the US if add solar panels this changes. The solar first powers your home, then refills you Powerwalls, and once the powerwalls are full sends power to the grid.

This is just a general pattern. There are settings that let you alter this behavior.

Thanks Can this export be limited to say max 5kw? My DNO will not allow any more. Appreciate Powerwall Gateway 2 is G99 certified limiting device, do I need my installer to set this or is it something I can do?

I suspect your installer would deal with this. It is definitely something you should discuss with them.

Also, sorry to hear there is a limit.
