The inverter is the "brain" of your system. It converts DC electricity from panels/batteries into AC electricity for home use.
Pure Sine Wave: Matches wall-outlet power. Smooth curve ensures motors run cool and quiet.
Modified Sine Wave: A "staircase" approximation. Those sharp jumps cause heat and humming.
| Type | Best Used For |
|---|---|
| String Inverter | Residential roofs with no shade. Simple and cost-effective. |
| Micro-inverters | Complex roofs with shade. One per panel = Maximum harvest. |
| Hybrid Inverter | Systems with Batteries. Manages both Grid and Backup power. |
Why the "Blocky" wave exists: Creating a smooth curve requires complex switching and expensive components. Budget inverters save costs by simply clicking the power ON/OFF in blocks (Modified Sine Wave).
Pro Tip: If an inverter box doesn't explicitly say "Pure Sine Wave" in large letters, it's almost certainly a "Modified" blocky model.
