Load management ensures your charging infrastructure never exceeds the capacity of your electrical supply — protecting fuses, avoiding grid penalties, and keeping all vehicles charging safely.

Node-level limits

Power and current limits are set on nodes in your topology. A limit on a node applies to the total load across all its children (sub-nodes and EVSEs).

• Current limit (A) — maximum current through this node
• Power limit (kW) — maximum power draw through this node

Set limits to match your actual fuse or supply capacity. The optimiser treats these as hard constraints — they are never violated.

Per-EVSE limits

In addition to node limits, you can set limits directly on individual EVSEs. This is useful when a charger has a lower rated capacity than the node it belongs to.

Amp buffer

The amp buffer is a configurable headroom below the node limit. When set, the optimiser will leave this amount of capacity unused — useful when other non-charging loads share the same circuit.

For example: node limit 100 A, amp buffer 10 A → optimiser treats 90 A as the effective limit.

Time-based limit schedules

Node limits and EVSE availability can vary by time of day using schedules. Examples:

• Reduce node limit during peak tariff hours (e.g. 07:00–22:00: 80 A, 22:00–07:00: 100 A)
• Make certain EVSEs unavailable for charging during certain windows

Schedules are set per node or per EVSE in the portal.

Fuse threshold lines on charts

When a node has a limit configured, that limit is shown as a threshold line on the monitoring chart for that node. This makes it immediately visible when you are approaching capacity.

External meters for dynamic load management

Static limits protect against predictable loads, but real-world sites also have variable non-charging consumption (lighting, HVAC, equipment).

Connecting an external meter feeds real-time consumption data into the optimiser — allowing it to dynamically adjust charge rates to keep total site load within safe limits, even as other loads fluctuate.
