Since 2002, we have followed thousands of micro-scale renewable and efficient energy systems working hand-in-hand with microfinance partners around the world. With off-grid project implementation in Latin America, Africa, Central Asia, South Asia and South East Asia, MicroEnergy International understands the importance of an end-user focused approach.
Guided by our experience and findings in the field, we have developed the MicroEnergy Supply System (MESUS), an intelligent electrification solution to address the challenges of rural energy services. Designed to supply off-grid households and micro-businesses with electricity independence, MESUS is also able to interlink the energy systems of multiple end-users, providing an expandable bottom-up approach to building mini-grids. We call this approach Swarm Electrification.
The controller at the core of the energy system, the MicroEnergy Usage Controller, optimizes the supply of energy based on the demand of the end-user. MESUS allows for customization according to the end-user’s needs, including the ability to connect various sources of distributed energy generation, such as solar panels, wind turbines or even diesel generators, as well as energy storage technologies, such as lead acid batteries. Through the use of this special charge controller, the unit protects the user’s battery from damage, while also allowing them the ability to define their priority loads should the battery run low.

MicroEnergy for MicroGrids:
Bottom-up Swarm Electrification
In a modular and phased approach, multiple MESUS systems are interlinked to build a flexible micro-grid, a swarm of household and businesses, each with their own energy supply system. The individual nodes are not only consumers of the electricity supply, but rather they also play an active role in the production of electricity, thereby moving away from the role of passive consumers towards that of prosumers in an active distribution network. The addition of new prosumers to the microgrid provides a balancing effect, optimizing supply and demand, and enabling wider electrification of the community. This approach aims to simplify the addition of new generation and storage capacity through compatibility with a variety of different sources, and even an interconnection point for central grid infrastructure. With swarm-based generation, consumption, and storage, sustainable energy independence is initiated by MESUS and managed by users themselves.
