What is SMA Smart Connected?

However infrequent they occur, service calls can be lengthy, unnecessary and will most certainly impact a PV installer’s bottom line. SMA’s new Smart Connected feature offers a proactive solution that saves installers time and money while maximizing system owners’ power production. This fully-automated functionality requires only a simple activation in Sunny Portal and a residential PV system will immediately benefit from SMA’s intelligent monitoring technology. No other solar solutions provider can offer this level of investment security, making SMA the ideal partner for residential PV.

How does SMA Smart Connected work?

Activation of SMA Smart Connected

Activation of SMA Smart Connected
During registration of the system in Sunny Portal, the installer simply checks a box to activate SMA Smart Connected which commences automatic inverter monitoring by SMA.

Automatic inverter monitoring

Automatic inverter monitoring
SMA automatically monitors the inverter to identify events around-the-clock. Both installers and their customers benefit from SMA's many years of experience diagnosing sophisticated inverter technology.

Proactive communication

Proactive communication
After a fault has been diagnosed and analyzed, SMA informs the installer and PV system operator immediately by email. So all parties are proactively prepared for the troubleshooting process ensuring minimum downtime and reducing truck roll costs.

Replacement Service

Replacement Service
In the rare event that a replacement component is necessary, SMA automatically supplies a replacement component within one to three days of the fault diagnosis. The installer can then contact the PV system operator of his/her own accord and repair the inverter immediately.

Power+ Solution:
Power with a Purpose

The SMA Power+ Solution combines legendary SMA inverter performance and intelligent DC module-level electronics in one cost-effective, comprehensive package. This means that you can achieve maximum solar power production for your customers while also realizing significant installation savings.
