This document translated from the original German version using Google Translate. Under the brand name "SolarMax" sells the Swiss company Sputnik Engineering AG photovoltaic inverter. The SolarMax inverters can be customized with normal Ethernet connection query, taking advantage of a (sort of) text-based protocol over a TCP connection. The protocol used was reverse engineered by me (using Network-capturing using the MaxTalk software). Only after implementation of the basic functionality I received yet still a documentation of the protocol used by the manufacturer. The license of this interface description, however, does not allow to make them publicly: | The user shall refrain from the data log Third | To be disclosed to.
