GCX EnergyGuard
Solar, Battery and Power Distribution Monitoring
Power Is the First Failure.
GCX EnergyGuard is the power-infrastructure layer of GCX One: solar output, battery state of charge and health, DC distribution and load, and fuel-cell status, monitored continuously and alarmed when they leave their safe range. It is built on hardware GCX One already integrates — Victron inverters, chargers and battery monitors, and EFOY fuel cells — and it exists because on a remote site the power system fails long before the camera does.
Key capabilities
- Continuous telemetry from solar charge controllers, battery monitors and inverters
- Battery state of charge, DC system voltage and load reported per site, not per estate
- Fuel-cell level, output voltage, internal battery charge and operating temperature
- Threshold alarms routed through the same alarm workflow as any security event
- Early warning on the conditions that take a site offline: depletion, underperformance, thermal and distribution faults
Primary use cases
- Off-grid towers and remote cameras running on solar with battery and fuel-cell backup
- Sites where a technician visit is expensive enough that it must be scheduled on evidence
- Winter and storm periods, where solar yield falls and battery reserve becomes the whole margin
- Estates that need to prove a site was powered, not merely that it was connected

Power event types
What is measured, and what it warns about
| Source | Measured | Warns about |
|---|---|---|
| Victron MPPT | Solar charging current and input power | An array underperforming against its own history |
| Victron battery monitor | Voltage and state of charge | Depletion before it reaches cut-off |
| Victron inverter | Operational status and load | Inverter fault and high load |
| EFOY fuel cell | Cartridge level, output voltage, temperature | A refill due, and thermal or output faults |
Architecture
Technical specifications
- Integration
- Victron VRM Cloud API
- Supported Hardware
- MPPT solar charge controllers, battery monitors, inverters
- Requirements
- An active VRM portal account with administrative privileges, a Cerbo GX or Color Control gateway, the device serial number, and a site already created in GCX One
- Telemetry
- Battery voltage across the DC system, solar charging current and input power from the PV controllers, battery state of charge as a percentage, charger and inverter operational status, overall system health and alarm state
- Events
- Battery Low, Grid Failure, Inverter Fault, High Load Alert
- Integration
- EFOY Cloud API
- Requirements
- An EFOY Cloud account, an EFOY Pro controller connected, a network gateway configured, the fuel-cell serial number, and an EFOY API key set once per tenant as a custom property named EFOYAPIKey
- Telemetry
- Fuel cartridge level as a percentage of remaining capacity, output voltage, internal battery state of charge, operating temperature, health and runtime status
- Events
- Low Fuel, Fuel Cell Fault, Battery Critical, Power Loss
- Device Dashboard
- Victron and EFOY devices show a device-specific dashboard rather than the standard alarm widgets
- Tower Context
- On a tower site the energy telemetry appears alongside the device list, so power and payload are read together
- Alarm Workflow
- Power events enter the same lifecycle as any other alarm: routed, escalated or acknowledged, then cleared automatically when the condition resolves
- Yield Forecasting
- Predicting solar generation against demand rather than reporting it after the fact
- Battery Lifecycle
- Replacement scheduling from measured health rather than from age
- Load Shedding
- Remote control of load priority on a constrained site
- Credential Requirement
- Victron VRM credentials must be administrative. A read-only account cannot retrieve the full telemetry set, and the result is a device that connects and reports almost nothing
- Tenant Key
- The EFOY API key is configured once per tenant. A missing or wrong key means no telemetry at all from every EFOY device under it
- Scope
- EnergyGuard monitors and alarms. It does not control the power system, and it does not replace the manufacturer own portal for commissioning that system
- Coverage
- Only what the integrated hardware reports. A generator or distribution board with no telemetry of its own is invisible to it

Governance & Limitations
Getting started
Each device is onboarded against an existing site and begins reporting immediately once its credentials are accepted.
- 01Set the tenant keyAdd EFOYAPIKey as a custom property at tenant level before adding any fuel cell
- 02Add the Victron deviceUnder the site, with VRM administrative credentials and the device serial number
- 03Add the EFOY deviceUnder the same site, with its serial number from the EFOY Cloud portal
- 04Set the thresholdsEnable the battery, voltage, fuel and temperature rules and confirm they route and clear correctly
