True independence, engineered to last

A microgrid is a self-contained energy system that can run connected to the main grid or stand entirely on its own. NexusCore builds microgrids around solar generation and substantial BESS capacity, with intelligent controls that decide, second by second, how to keep every critical load powered. For properties at the end of a fragile feeder, remote operations far from any network, or facilities that simply cannot tolerate an outage, a microgrid delivers the holy grail of energy independence: reliable power regardless of what the wider grid does. When the network drops, the system islands automatically, often so fast that sensitive equipment never notices.

Going off-grid is an engineering discipline, not a leap of faith. We model your loads across seasons, size solar and storage for worst-case low-generation periods, and design redundancy so a single fault never goes dark. Where appropriate, we include a generator as a deep-backup layer, but the goal is for solar and BESS to carry the load the overwhelming majority of the time, minimising fuel, emissions and running costs.

Islanding and BESS Autonomy

Islanding is what separates a real microgrid from a simple solar array. Our controllers continuously manage frequency and voltage so the system can disconnect from the grid and run as its own stable network. The BESS is the anchor, absorbing solar surplus during the day and dispatching it through the night, while the control logic prioritises critical circuits if reserves run low. This autonomy means a multi-day grid outage or a remote site with no connection at all is simply business as usual.

• Seamless automatic islanding that protects sensitive equipment
• BESS sized for multi-day autonomy through low-generation periods
• Critical-load prioritisation when reserves are constrained
• Optional generator backup as a deep-redundancy layer
• Remote monitoring and predictive maintenance for unattended sites

Grid-Connected Microgrids and Revenue

Not every microgrid is fully off-grid. Many of our clients stay connected but gain the ability to island on demand, giving them resilience plus the option to trade. A grid-connected microgrid can shift load away from peak tariffs, export stored solar when prices are high and participate in virtual power plant and grid-services programs. This turns a resilience investment into a revenue-generating asset, improving return on investment while still guaranteeing power when the network fails.

Built for Remote and Critical Operations

Microgrids shine where reliability is non-negotiable, agribusiness, mine sites, telecommunications, emergency facilities and remote communities. NexusCore engineers for harsh conditions and minimal site visits, with robust hardware, redundant controls and remote diagnostics that catch issues before they become outages.
