DIY Home Solar System for under $5000

Living in Puerto Rico, I witnessed firsthand how fragile our power grid is, especially after Hurricane Maria. With no electrical engineering background, I researched and built a reliable solar backup system for under $5,000. This guide shares the essential components, cost-saving tips, and design steps to help you achieve energy independence and protect your home from outages.
For them, a reliable power supply isn't a luxury-it's a necessity.

This is freqently, dangerously, wrong- and is missing critical information.
I saw no discussion of:
* C rate
* fuse selection
* inverter precharge (capacitive loads)
* cell level monitoring
not all batteries are series compatible.
* fail modes
But, in a sentence: No more than 100Ah and 12v for your first build.
Theres a million more things- like terminal preperation, torque specs, fire precations.
