Supervisory system controller for use with a renewable energy powered radio telecommunications site
First Claim
1. An apparatus for controlling and monitoring the generation of electrical energy from renewable sources, said apparatus being operable to manage storage of energy generated from renewable sources by controlling interconnection of energy generating elements, energy storage elements and energy load elements, said apparatus being operable to communicate with a remote device to obtain weather forecast data for the purpose of predicting future renewable energy generation capability;
- and manage storage of energy generated from said renewable sources based upon said prediction of future renewable energy generation capability, and said apparatus further comprising a plurality of disconnect devices to allow independent disconnection of individual loads from a DC bus according to an algorithm that uses voltage levels, battery state of charge, time and override command, to manage said storage of energy generated from said renewable sources.

Abstract
A supervisory system controller for controlling and monitoring the generation of electrical energy from renewable sources and management methods for the storage of energy so generated and interconnecting the energy-generating elements, storage and load. The supervisory system controller operates to maximum the power transfer from a wind turbine to a battery by automatically varying the threshold levels at which turbine dump loads are switched based on system inputs and measurements. The method conserves generator fuel by delaying a scheduled generator maintenance running period such that it occurs when renewable energy availability is predicted to be low and battery is in a reduced state of charge. Further modifications and management methods are also provided.
