What is Cloud Based Load Balancing?

EVSEs can coordinate to keep the total current within site limits while still serving drivers.

What Is Load Balancing?

Load balancing lets multiple chargers share limited electrical capacity safely and efficiently. It prevents overloads, reduces or avoids costly service upgrades, and improves charger availability across MURBs, commercial sites, and fleets.

This can be done:

• Offline (local): Chargers coordinate among themselves—no network required.

• Online (cloud): The platform manages power across many chargers/panels/sites with remote policies.

Cloud-Based Load Balancing (Enterprise Plus & Core)

Best for: Larger or multi-panel sites that need remote control, user rules, and scalability.

• What you get: Remote configuration, real-time monitoring, user prioritization, and dynamic power allocation across panels/sites. Installers bring units online—Electric Avenue programs the policies based on your circuit info.

Four Online Strategies (with examples & diagrams)

Circuit-Level

• A group of chargers shares one branch circuit (e.g., 60A with a 48A cap).

• Example: First EV gets up to 48A; when a second plugs in, each may receive ~24A/24A to stay under the breaker limit.

  

Panel-Level

• Each charger has its own breaker, but the platform caps the total panel draw (e.g., 200A).

• Example: With 8 chargers on a 200A, simultaneous use might limit each to ~25A to protect the main breaker.

 

Multi-Level

• Applies caps at multiple points (per-panel “child” and upstream “parent” service/transformer).

• Example: 4 circuits × 3 chargers (48A) feeding a 200A panel; as utilization rises, individual outputs may drop to ~16A while honoring both circuit and panel limits.

 

Dynamic (Whole-Building) Load Balancing

• CTs at the main switchboard/transformer measure total building load; EVSE output ramps up/down to fit available headroom—in real time.

• With Electric Avenue’s Wattch CT kit + Enterprise Plus, EV loads can be zero-rated in service calculations per CEC, enabling large deployments without service upgrades.

Which Strategy Should I Choose?

Site Profile	Recommended Approach
Several chargers, single panel limit	Panel-Level
Many chargers across multiple subpanels	Multi-Level
Building with variable non-EV loads; want to avoid upgrades	Dynamic (CT-based)
Small shared circuit and you want “set-and-forget”	Circuit-Level

Enterprise Basic (Circuit-Level Load Management)

Available for circuit-level load management only. Multiple chargers will be able to load balance on a single breaker or circuit.

• Supports up to 60 amp circuits for Watti Pro Series 48A chargers
• Supports up to 100 amp circuits for Watti Pro Series 80A chargers

Installation Notes & Best Practices

• Document breaker/panel limits before commissioning; match rotary switch to real capacity.

• Prefer Ethernet for cloud sites; Wi-Fi/LTE as needed.

• Start with conservative caps; adjust after observing usage.

• For fleets/MURBs, pair load balancing with idle time policies to improve turnover.

 

FAQ

Q: Do installers have to configure the cloud software?
A: No. Once online, Electric Avenue programs the setup from your circuit info

Q: Can we expand later without a service upgrade?
A: Yes—panel-level, multi-level, and dynamic strategies help scale within existing capacity
