Best String Inverters
We like the German made SMA Sunny Boy line. There are a number of sizes available for residential projects:
- SMA Sunny Boy 3.0 kW
- Sunny Boy 3.8 kW
- SMA Sunny Boy 5.0 kW
- Sunny Boy 6.0 kW
- SMA Sunny Boy 7.0 kW
- Sunny Boy 7.7 kW
One nice feature unique to the Sunny Boy US model version is the Secure Power Supply (SPS), a plug which can output 2000W of emergency power in case of grid outages. The SPS functionality is limited to times when the sun is still shining (as it still draws power from your panels, merely bypassing the grid interconnection). But it’s still a nice backup plan in a pinch.
The SMA can also be retrofitted with optimizers to mitigate production drop (more on this in the next section). However, adding optimizers comes with the trade-off of losing the SPS functionality.
String inverters are generally the most common and affordable inverter option and function best if your roof has plenty of exposure to sunlight. Micro-inverters and power optimizers offer similar benefits but operate in different ways, best suited for roofs that have shading or are oriented in different directions.
To determine the top 5 most used solar inverter brands for PV hybrid systems (with solar batteries), we reviewed the data from all of our projects from the past years.

- Huawei
