This energy controller seems to be pretty good for controlling a stand alone solar battery system and wind generator system together located in a remote site. A brief interpretation and summary of the product catalogue written in Japanese are attempted by me as follows.
This device controls charging and discharging electric power generated both by a wind generator and photovoltaic power generator. This hybrid controller has features all-in-one required for an ecological power generation system of 12-250W or 24V-500W. Applications areas of this controller will be stand alone systems, such as emergency lighting, street lighting, eliminating, water-pumping and so on. With data communication interface, this controller can communicate with a central control office where all the data is monitored and controlled. Dimensions are Ｗ１２０×Ｈ３００×Ｄ８０ｍｍ.
