DIY Home Power Guide

Start with loads, goals, constraints and safety before choosing equipment or following a DIY power plan.

Start with requirements

Start with the job the system must do. List loads, peak power, daily energy and desired runtime before selecting generation or storage.

Think in systems

A complete system is more than a headline component. Source, conversion, storage, protection, wiring, controls and loads must work together within equipment ratings and local requirements.

Questions worth answering

• What exact loads need power, and for how long?
• What peak or startup demand must equipment handle?
• What installation, ventilation, protection or code constraints apply?
• What happens when expected generation, charging or fuel is unavailable?
• Which assumptions can you measure before spending money?
