Why Your DIY Solar System Needs Insulation Monitoring (Before Something Goes Wrong)

Check your solar system’s ground fault protection monthly by verifying the insulation resistance between your DC circuits and ground stays above 500 ohms per volt of system voltage. Install an insulation monitoring device (IMD) on any off-grid system over 48 volts or grid-tied system operating without galvanic isolation to catch deteriorating wire insulation, damaged solar…

Why Your Concrete Steps Need Solar Lights (And How to Install Them Right)

That moment sparked my journey into…

Why Solar Alone Isn’t Enough: Five Energy Sources That Complete Your Off-Grid System

Combine multiple power sources to create a resilient energy system that keeps your home running when solar panels can’t produce electricity. Start by identifying which backup sources match your property’s natural resources—flowing water, consistent wind, or reliable grid access—then layer them strategically so you’re never dependent on a single energy supply. This approach transforms solar…
