4.5 Communication Interface
The inverter can be fitted with a communication interface (e.g. RS485 or Speedwire with Webconnect
function). This communication interface enables the inverter to communicate with SMA communication
products or other inverters (for information on supported products, see www.SMA-Solar.com).
You can only set the inverter parameters via SMA communication products.
Depending on the type of communication, RS485 or Speedwire, the parameters and messages are
displayed differently on the communication products.
You can adjust the country data set of the inverter before commissioning or within the first ten
operating hours via the two rotary switches in the inverter. All other operating parameters can only
be set via communication products.
4.6 Secure Power Supply (SPS)
The inverter has an SPS module that can supply the PV array energy to an additional outlet connected
to the inverter in the event of grid failures of longer durations. The SPS module also has a connection
for the fan retrofit kit, enabling an external fan to be controlled.
4.7 Fan Retrofit Kit
The fan retrofit kit is used for additional inverter cooling at high ambient temperatures (for information
on installation and configuration, see the fan retrofit kit installation manual). The fan retrofit kit can be
retrofitted, installed at the factory if specified in the order, or included in the regular scope of delivery.
The Sunny Boy 6000TL-US, 7000TL-US and 7700TL-US are equipped with a fan as standard.
