NEC-Compliant Load Management
Add a high-demand load, without upgrading your electrical panel.
Nature's Generator's Energy Management System monitors your total electrical demand and intelligently manages high-demand 240V loads, so you can add an EV charger, air conditioner, electric water heater, pool heater or fast-charge a solar generator or energy storage system on your existing electrical service without a $6,000+ electrical panel upgrade.
- 40A/60A Load Capacities
- 120V/240V Service Compatible
- NEC Compliant

Load automatically shed at threshold – managed circuit disconnects before your service is exceeded, then restores itself.
The Problem
Want to Add an EV Charger or High-Demand Appliance? Your Existing Electrical Service May Not Have the Capacity.
Adding an EV charger, air conditioner, electric water heater, pool heater, or fast-charging a solar generator or energy storage system can significantly increase your home's electrical demand. A load calculation may show that your existing 100A or 125A service doesn't have enough available capacity.
The traditional solution may be an upgrade to 200A service, adding significant cost, permits, utility coordination, and installation time.

There is a code-compliant way to avoid the upgrade, that's what an Energy Management System does.

Upgrading can cost more than you think.
It's not just the equipment. It's everything that comes with it.

The Solution
An NEC-approved way to add power without adding capacity.
An Energy Management System is an NEC-approved device that monitors, controls, and — when needed — temporarily limits electrical loads so they don't all run at once.
Key Principle
Approved EMS systems reduce calculated demand by automatically preventing high-demand loads from running at the same time, keeping your home within its existing service capacity.
- NEC Compliant — code-approved solution
- Cost Effective — a fraction of an upgrade
- Fully Automatic — no user intervention
Process
How Nature's Generator EMS works
Four steps, running continuously, with no action required from you.
-
01
Continuous Monitoring
Dual current monitors track total service demand in real time across both 120V legs, amperage, voltage, and calculated wattage.
-
02
Intelligent Control
As demand approaches your configured threshold (typically 80% of service capacity), the EMS prepares to act.
-
03
Load Shedding
The managed load, EV charger, heat pump, etc., is temporarily disconnected, keeping total demand in range.
-
04
Automatic Restoration
Once demand drops, power to the managed load is restored automatically. No resets, no app, no user action.
The Math
Skip the upgrade. Keep the capability.
The financial case, side by side.

Certification
Independently tested. Certified to national safety standards.
The EMS carries the cETLus mark, confirming independent, third-party testing against the exact standards written for this category of equipment, for both the U.S. and Canada.
Certified by Intertek
Intertek is an independent, OSHA-recognized Nationally Recognized Testing Laboratory (NRTL), the same class of authority as UL. The cETLus mark means the EMS was independently tested and listed for use in both the United States and Canada.
- Independent third-party testing
- OSHA-recognized NRTL
UL 916 / CAN / CSA-C22.2 No. 916
The specific safety standard written for Energy Management Equipment – devices built to monitor and control electrical loads. This confirms the EMS is built to the requirements set for its exact product category, not a general-purpose standard.
- Energy Management Equipment
- U.S. & Canada
UL 60730-1 / CSA E60730-1
Covers the general safety requirements for automatic electrical controls – the part of the EMS that disconnects and restores a managed load without anyone touching it. This is the standard that governs the "automatic" in automatic load shedding.

FAQ
Frequently Asked Questions
Everything you need to know
Which model should I choose: 40A or 60A?
Choose the 40A model for plug-in loads on receptacle circuits, such as EV mobile chargers and NEMA 14-50R outlets. Choose the 60A model for hard-wired loads such as EV stations, heat pumps, and well pumps.
Is this NEC compliant?
Yes. The Energy Management System is an NEC-approved device. It carries the cETLus mark and is tested to UL 916 / CSA-C22.2 No. 916 for energy management equipment and UL 60730-1 / CSA E60730-1 for automatic electrical controls.
Does this require professional installation?
Yes. Installation should be performed by a qualified electrician in accordance with local code. It mounts alongside your existing panel, uses standard electrical connections, and is typically completed in a single visit.
How does load shedding work?
The EMS monitors total demand across both 120V legs. When demand approaches your configured threshold, it temporarily disconnects the managed load so the service stays within capacity, then restores power automatically once demand drops.
Will I notice when loads are disconnected?
The managed circuit is disconnected only while total demand is near your service limit, then restored automatically. No reset, app, or user action is required.
What maintenance is required?
Once installed, the system works automatically. No ongoing maintenance is required.
Is this compatible with solar systems?
Yes. It works with existing solar installations and monitors total household consumption regardless of power source. It is built for standard 120V/240V split-phase service, including split-phase plus solar. It is not compatible with 120V-only systems.
