The System Planner

Plan the whole system—one decision at a time.

Our sizing guide starts with the energy you actually use, then takes you through panels, batteries, voltage, inverter capacity, and protection.

Practical answers, in the order they matter.

Alternative generation, honestly calculated

Before you build a DIY generator, calculate what it can actually produce.

Micro-hydro, wind, pedal power, and storage experiments can teach you a lot. The Project Lab puts feasibility, safety, and real output before the build list.
