What Kind of Inverter Do You Need?
The right inverter technology depends on your roof’s layout, shading, and your future energy goals. Follow this guide to see what fits best.
String Inverters
Best for simple, unshaded roofs. Multiple panels are connected in a ‘string’ to a single inverter.
Ideal For: Uniform Sun Exposure
Most cost-effective solution.
Microinverters
A small inverter for every single panel. Maximizes output by letting each panel perform independently.
Ideal For: Complex or Shaded Roofs
Panel-level monitoring and top safety.
Power Optimizers
A hybrid approach. Small optimizers on each panel improve performance, sending power to one main string inverter.
Ideal For: Shading & Mixed Orientations
A balance of cost and performance.
Hybrid Inverters
The future-proof choice. Manages power from solar panels and a battery, enabling energy storage.
Ideal For: Energy Independence
Store excess solar power for night use.
