PV Inverters with Sunny Home Manager
PV inverters can communicate in two different ways in SMA Smart Home with the Sunny Home Manager:
Wired via Ethernet
The inverter must be connected to the local network via a network cable (e.g. via a router).
Wireless via WLAN
Depending on the ambient conditions, wireless networks can have a limited range. In free-field conditions without any disruptive objects, a high radio range is possible. Inside buildings, obstacles such as walls, ceilings and doors or other sources of interference can reduce the range to a few meters. Range problems can be eliminated with standard WLAN repeaters.
Wireless via WLAN
Despite a good radio connection, there may be temporary interruptions in communication. SMA Solar Technology AG therefore generally recommends a wired connection via Ethernet.
The Sunny Home Manager supports all PV inverters with integrated or retrofitted Speedwire interface of SMA Solar Technology AG. The PV inverters must have the current firmware version in each case (see the inverter product page at www.SMA-Solar.com).
No support for the Sunny Boy 240 and the Sunny Multigate
The Sunny Boy 240 and the Sunny Multigate are not intended for use in Sunny Home Manager systems. Although the Sunny Home Manager can detect the Sunny Multigate, use of the Sunny Home Manager for the configuration of this inverter is not recommended. SMA Solar Technology AG does not accept liability for missing or incorrect data and any yield losses that may result.
Data on PV generation from the PV inverter
All compatible SMA PV inverters can transmit their PV generation data directly to the Sunny Home Manager. For this reason, a separate PV production meter is not necessary.
If inverters from other manufacturers are to be integrated into the systems, an SMA Energy Meter must be installed centrally as a PV production meter. The PV production meter is then configured appropriately via the Sunny Home Manager settings in Sunny Portal. The generation data from SMA PV inverters is no longer used. For this reason, dynamic active power control in such mixed systems is no longer possible. The inverters must be limited to a fixed active power limit.
Maximum number of supported PV inverters
The Sunny Home Manager supports a maximum of 24 SMA inverters within one system. This is also the maximum number of devices.
With 24 SMA inverters within one system, radio-controlled sockets or directly controllable loads can no longer be supported.
