SMA Sunny Boy 1.5 / 2.0 / 2.5 with SMA SMART CONNECTED


The new standard for small PV systems
The Sunny Boy 1.5 / 2.0 / 2.5 is the perfect inverter for customers with small PV systems. Thanks to its broad input voltage range of 80 V to 600 V, its versatility, flexibility in module compatibility and low weight for easy installation are impressive. After smooth commissioning via the integrated web interface, the Sunny Boy 1.5 / 2.0 / 2.5 is ideal for local monitoring via the device’s own wireless home network or for online monitoring with Sunny Portal or Sunny Places. Thanks to its integrated SMA Smart Connected service, this inverter offers ease and comfort for PV system operators and installers. The automatic inverter monitoring by SMA analyzes operation, reports irregularities and thus minimizes downtime.

Integrated service for ease and comfort
SMA Smart Connected* is free monitoring of an inverter via the SMA Sunny Portal. If an inverter fails, SMA proactively informs the PV system owner and the installer. This saves valuable working time and costs. With SMA Smart Connected, the installer benefits from rapid diagnoses by SMA. They can thus quickly rectify the fault and score points with the customer thanks to the additional, attractive services.

Activate on of Smart Connect
During registration of the system in the Sunny Portal, the installer activates SMA Smart Connected and benefits from automatic inverter monitoring by SMA.

Automatic inverter monitoring
SMA takes on the job of inverter monitoring with SMA Smart Connected. SMA automatically checks the individual inverters for anomalies around the clock during operation. Every customer thus benefits from SMA’s many years of experience.

Proactive communication in the event of faults
After a fault has been diagnosed and analyzed, SMA informs the installer and end customer immediately by email. Everyone is thus optimally prepared for the troubleshooting process. This minimizes downtime and saves time and money. Regular power reports also provide valuable information about the overall system.

Replacement service
If a replacement device is necessary, SMA automatically supplies a new inverter within one to three days of the fault diagnosis. The installer can contact the PV system operator of their own accord and replace the inverter.

Performance Service
The PV system operator can claim compensation from SMA if the replacement inverter is not delivered within three days.
