Diy solar power design

[Gulam Solar]

Hello All,

I think I’ve designed my solar system for residential power.
I based my calves on 16kwh per day peak power of say 5000w
What I’m having issues with is battery back up solution with 3 days autonomy for a grid tied solution my calls compute at around 67kwh
The inverter or charge controller are above my expertise can someone help
