Load management to scale your charging network without upgrading electrical infrastructure
Monta Load Management distributes available current across your chargers in real time, adapting to building consumption as it changes. Install chargers behind shared fuses without panel upgrades, transformer replacements, or lengthy permitting delays.

Electrical infrastructure limits network growth
Expanding charging networks often requires expensive electrical upgrades: new transformers, panel replacements, and months of permitting delays. Existing installations may experience breaker trips during peak hours when building and charging consumption overlap.
Without real-time visibility into available capacity, charging networks face a trade-off between overprovisioning electrical infrastructure or accepting reduced reliability during peak demand.
Automated power distribution addresses these challenges by intelligently balancing building load fluctuations while maintaining service quality at scale.
Modular load management
Static load management for predictable sites
Best for predictable sites where building consumption is stable or minimal. You set a fixed fuse limit for a group of chargers, and Monta distributes the available current evenly or by priority.
- Use case: Dedicated EV parking lots, overnight fleet depots, sites with separate EV-only panels
- Configuration: Set max current per site/group, configure buffers, choose power distribution method (even split or priority-based)
- Rebalancing trigger: Charge start/stop events
- No external meters required
Dynamic load management with real-time rebalancing
Best for multi-use sites where building consumption fluctuates throughout the day. External meters monitor total building load in real time, and Monta adjusts EV charging to stay within panel limits.
- Use case: Workplace campuses, residential complexes, retail sites, mixed-use buildings
- Meter integrations: Perific, ABB Modbus, MQTT, Viocon
- Configuration: Multi-level groups (main fuse → sub-panels → circuits), scheduled power limits by time of day, phase-level monitoring
- Rebalancing trigger: Meter reading updates (every 5 minutes) + charge events
- Real-time visibility: See building consumption vs. available capacity per phase
Locally managed load balancing with cloud oversight
Best for sites with chargers that have built-in local load balancing capabilities. The hardware handles distribution locally, and Monta monitors compliance and performance.
- Use case: Single-brand hardware deployments with native balancing support
- Configuration: Enable local management mode in Monta Hub, set site-level limits
- Rebalancing: Handled by charger firmware
- Monta’s role: Oversight, audit logging, API-level reporting

Load management built for complex electrical topologies
Multi-level groups
Model complex panel hierarchies: main fuse, sub-panels, individual circuits; matching the actual electrical topology rather than forcing a flat structure. Nest groups to any depth.
Scheduled power limits
Shift available capacity by time of day. Reserve headroom during peak hours, open it up overnight. Set weekday vs. weekend schedules per site or group.
Compensation detection
Detects when a charger draws more than allocated (e.g., due to firmware bugs or meter drift). Triggers immediate rebalancing to prevent fuse trips.
Audit-grade reporting
API-level current logs for electrical compliance verification. Prove you never exceeded the fuse rating. Electricians and facility managers can verify via dashboard or export.
External meter integrations
Perific, ABB Modbus, MQTT, Viocon. Read building consumption in real time, subtract from panel capacity, distribute remainder to chargers.
The new operating reality
Avoid infrastructure upgrades
Install chargers without expensive panel upgrades
Eliminate manual throttling
Stop manually throttling chargers during peak hours

Load Management: An engineers view into controlling of EV charging infrastructure
As EV adoption surges, so does the strain on local electrical infrastructure. Monta’s Load Management system ensures that even the most constrained sites, such as fleet depots, public hubs, and workplace chargers, can scale safely and intelligently, without costly grid upgrades.
FAQs
What's the difference between Static and Dynamic Load Management?
Static Load Management uses a fixed fuse limit that you configure once. Best for sites where building consumption is predictable or minimal (e.g., dedicated EV parking lots). Dynamic Load Management uses external meters to monitor building consumption in real time, adjusting EV charging limits to stay within panel capacity. Best for multi-use sites where building load fluctuates (e.g., workplace campuses, residential buildings).
Which external meters does Monta support?
Perific, ABB ModBus, MQTT, and Viocon. Meters must provide real-time current readings per phase. Contact sales to verify compatibility with your existing meter infrastructure.
Can I use Load Management with hardware from different manufacturers?
Yes. Monta Load Management works with any OCPP 1.6 or 2.0.1 charger. You can mix hardware brands within the same site or group, and Monta will distribute load across all connectors regardless of manufacturer.
What happens if a meter fails or loses connection?
Monta detects meter communication failures and can revert to a safe fallback mode (static limits) to prevent fuse overload. You’ll receive alerts when meter connectivity is lost. Configure buffer limits to ensure safety during meter outages.
How often does Monta rebalance chargers?
Static Load Management rebalances on charge start/stop events. Dynamic Load Management (with meters) rebalances every 5 minutes when meter readings update, plus on-demand when a charge starts or stops. Locally Managed rebalancing frequency is determined by the charger firmware (e.g., Easee handles this natively).
Can I schedule different power limits for peak vs. off-peak hours?
Yes. Scheduled power limits let you define different fuse limits by time of day (e.g., reserve headroom from 8am-6pm weekdays, open full capacity overnight and weekends). Available on Business and Enterprise plans.
How do I prove compliance to electricians or facility managers?
Monta provides API-level current logs showing timestamped consumption per phase and per group. Export reports to prove you never exceeded fuse ratings. Electricians can verify compliance via the dashboard or request log exports.
