There are only a two serious options to protect your system.
1. Insurance
2. Dedicated Solar Power with battery storage or floated batteries on mains power using an inverter.
Although I live in a high lighting strike area, almost everything in my house was blown up by the Electric Company when they put 220v on my neutral and fed the whole road with 440v.
Almost $10k of damage to A/C units, TVs, fridges only things that survived were electric oven and hob and LED lighting.
Still fighting for a settlement even though they admitted fault.
Lucky most of my Hi-End gear was at another house.
