Micro vs String Inverter Installation: Mounting Differences Explained
Micro-inverters and string inverters mount very differently. Here's how installation and mounting hardware compare — and what it means for your bracket choice.

A string inverter is a single box mounted on a wall or frame, with all panels wired to it. Micro-inverters are small units mounted under or beside each panel, on the rail or balcony bracket. That changes where and how you mount the hardware.
| Aspect | String inverter | Micro-inverter |
|---|---|---|
| Mounting location | Wall / frame, one unit | Under/beside each panel, on rail or bracket |
| Bracket type | Wall or outdoor inverter bracket | Micro-inverter rail/balcony bracket |
| Quantity of mounts | One | One per micro-inverter |
| Best for | Larger, simple roofs/ground | Complex roofs, shading, balcony PV |
What It Means for Mounting Hardware
String systems need one robust wall or outdoor inverter bracket. Micro-inverter systems need a compatible-fit micro bracket at each unit — for Hoymiles, Deye, APsystems or universal — fixed to the rail or balcony rail. For balcony PV (popular in Germany), the micro-inverter usually clamps to the balcony bracket with no drilling.
Which Should You Choose?
Micro-inverters suit shaded or complex roofs and balcony/plug-in PV; string inverters suit larger, unshaded arrays at lower cost per watt. Your choice sets the mounting hardware — use our selector to match it.
Common Questions
Do micro-inverters need a different bracket than string inverters?
Yes — string inverters use a single wall/outdoor inverter bracket, while micro-inverters use a small compatible bracket at each unit, fixed to the rail or balcony bracket.
Which is better for balcony solar?
Micro-inverters — balcony (plug-in) PV systems almost always use a micro-inverter clamped to the balcony bracket, often with no drilling.
How many mounts do I need for micro-inverters?
One per micro-inverter, plus the panel mounting. We supply compatible micro brackets and balcony mounts to match your inverter and rail.
