Xemex and Cast4All launch the SUNGATE at Intersolar: direct readout of an inverter via GPRS/4G cellular communication

During the Intersolar fair in Munich, the SUNGATE will be launched.

Communicating energy data independently of the internet connections of residents and at low cost: the Sungate communication module by Xemex maximizes the yield of solar panels on the roofs of ground-level and high-rise homes.

The cloud software by Cast4All analyses the data and makes it possible to communicate this via an Application Programming Interface (API) with external software applications.

The Sungate is a handy and stylish communication module – fitted with a sim card – that is easy to install beside the inverter already present in the dwelling. The device is connected via a cable to the inverter’s RS485 communication port, enabling it to read data directly from the inverter.

The Sungate is brand-independent and works on every SunSpec compatible inverter.

Secure GPRS-communication

Communication runs via standard GPRS, but the module is suitable for future communication technologies, such as 4G, NB-IoT, LTE-M and LTE Cat 1. To keep the monthly data volume low, the log files are read twice a day. A higher frequency is of course also possible.

Transparent mode

Programming extra security, implement changes to the firmware or alter parameters remotely?
This is all possible using the transparent mode (optional).
Transparent mode is an extra configuration tool for modifying the inverter yourself remotely.


De Sungate cloud software contains optimization algorithms and an integrated problem detection.
External applications and portals can be coupled via the API.
