How to Choose the Right Size Solar Inverter: Step-by-Step with
Wondering what size solar inverter do I need for your solar system? This guide walks you through calculating inverter size based on panel capacity, power usage, and safety
Your inverter size should match your solar array's capacity, not your electricity bill. This means your inverter doesn't need to power your entire home—it just converts whatever your panels generate. Let's say you have a 6kW solar array (twenty 300-watt panels).
The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.
Think of inverter sizing like choosing the right-sized engine for your car. Too small, and you'll struggle on hills. Too large, and you're paying for power you'll never use. The sweet spot maximizes both performance and value. It's a common misconception that inverter size should match your home's energy usage.
1. Introduction: Why Inverter Size Matters An inverter converts DC power (from batteries or solar panels) into AC power (for household appliances). Picking the wrong size can lead to:
