Automatic DC solar disconnect

[Stryker777]

This may be a silly question. I'm new to this. Getting ready to set up a Flexboss and GridBoss with 3 Power Pro batteries. I'll have 15kw of potential solar input from my ground mounted arrays starting 100ft away from my home. We have lightning issues in the area and I'm trying to find the best way to protect from lightning. I've got SPDs for the arrays and a disconnect. I'd like a little more safety in case I'm not around though. Are there automatic disconnect switches I can install at the array end to disconnect it when there isn't enough UV to produce energy anyway? I'd feel much better if it's all disconnected when it can't produce energy.
Thanks for reading my long question.

The top two are good to 900V/500A. You would simply need a control mechanism and supply/remove low voltage to energize/de-energize the coil.
