The GEMS Smart Energy Controller
Engineered by New Energy Grid to turn your electrical installation into an automatic money-saving machine. One compact DIN-rail controller in your cabinet paired with a crystal-clear live portal at ems.newenergygrid.com — plug-and-play, ultra-fast, and effortless to use.
"While ordinary energy apps lag in the cloud and stop working if Wi-Fi drops, the GEMS Controller reacts right inside your cabinet in under one second — slashing peaks, trading cheap hourly power, and keeping employer EV billing intact."
Why the GEMS Controller Beats Ordinary EMS Systems
Not all energy management systems are created equal. Compare the dedicated GEMS Controller against typical P1 Wi-Fi dongles, single-brand inverter apps, and cloud-only load balancers.
| What Matters Most | The GEMS Controller | Typical EMS Dongles & Cloud Apps |
|---|---|---|
| Reaction Speed & Main Fuse Safety | Reacts on-site in under 1 second — main fuses never overload | Slow 5–15 min cloud polling that reacts too late when loads spike |
| When Internet or Wi-Fi Goes Down | 100% autonomous — keeps protecting & saving offline 24/7 | Loses control or drops EV chargers to trickle speed |
| Company EV Charge Card & Split-Billing | Keeps automatic employer reimbursement 100% intact | Takes over the charger connection and breaks split-billing |
| Belgian & Dutch Tariff Intelligence | Fluvius 15-min peak shaving, GSC shield, zero-export & hourly EPEX trading | Basic solar timers that ignore capacity peaks or green certificates |
| Hardware Quality & Reliability | Dedicated industrial DIN-rail controller with durable solid-state memory | Consumer plastic Wi-Fi dongles or fragile memory cards that wear out |
| Solar, Battery & Charger Harmony | Built for our Solis + LiFePO4 + RAEDIAN stack + 80+ major brands | Locked into one manufacturer's closed ecosystem |
Rock-Solid On-Site Power + Effortless Anywhere Access
GEMS combines a dedicated smart controller inside your electrical board with a sleek live portal on your phone and computer — giving you instant local protection and complete visibility wherever you are.
The GEMS Controller — Instant On-Site Intelligence
Neatly mounted on your DIN rail with industrial solid-state components, the physical GEMS Controller (GRID-EMS) is the tireless brain of your building. It reads your smart meter and directs your solar inverter, battery, heat pump, and EV chargers every single second — even during multi-day internet outages.
- Adjusts battery power and EV charging in under 1 second to protect your main fuse
- Connects directly to your digital P1 smart meter, solar inverter, battery, and chargers
- Guided 3-click browser setup with automatic equipment detection — zero programming
- Industrial solid-state memory stores years of energy history safely on-site
The GEMS Cloud Portal — Live Insights From Anywhere
Your GEMS Controller connects automatically and securely to our live cloud portal (GRID-EMS-SERVER at ems.newenergygrid.com) — with zero router adjustments, no IT headaches, and instant access for homeowners, businesses, and installers.
- Automatic daily download of tomorrow's hourly EPEX Spot electricity prices
- Single-screen overview of one home or dozens of business and fleet locations
- Switch savings modes, boost EV charging, or adjust battery reserves remotely in one tap
- Never loses a data point: offline history syncs automatically once internet returns
Four Smart Ways GEMS Lowers Your Energy Bill
Purpose-built for Belgian and Dutch energy bills — handling capacity peaks, green certificates, negative feed-in tariffs, and dynamic hourly contracts automatically.
1. Eco Mode — Use Every Drop of Your Own Solar Power
Before a single kilowatt of free sunshine leaves for the street at low feed-in rates, GEMS stores it straight into your LiFePO4 battery, modulates your EV charger to follow the sun, and warms your heat pump.
- Real-time solar surplus routing to your battery & electric car
- Smart heat pump & boiler boost using free daytime sunshine
2. Capacity Peak Shaving & Green Certificate Protection
Watches your rolling 15-minute Fluvius demand clock every second. When cooking, heat pumps, and EVs run together, GEMS discharges your battery and trims EV power to stay below your peak ceiling — while never curtailing solar panels that earn valuable Green Certificates.
- Smart Adaptive Ceiling prevents expensive monthly Fluvius peak penalties
- Protects Groenestroomcertificaten (GSC €90–€450/MWh) automatically
3. Zero-Export & Negative Feed-In Price Shield
Say goodbye to paying penalties for exporting solar power on sunny afternoons. When grid export prices turn negative or feed-in limits apply, GEMS fills your battery and EV first and smoothly throttles solar output to match building use.
- Automatic zero-export & grid feed-in limit control
- Instant shield against negative solar export charges
4. Automatic Hourly Tariff Trading (EPEX Spot)
Fetches official day-ahead hourly electricity prices every afternoon and calculates your true all-in price including taxes, grid fees, and supplier formulas (presets built in for Engie, Luminus, TotalEnergies, Eneco, Mega, Bolt, Frank Energie, Ecopower, Dats 24, Octa+ and more).
- Charges your battery & EV automatically during the cheapest night or afternoon hours
- Powers your building from stored battery energy during expensive evening peaks

Balance 1 to 64 EV Chargers — Without Losing Employer Split-Billing
Here is the frustrating secret of most load balancers: they take over your EV charger's cloud slot and break automatic company charge-card reimbursement. The GEMS Controller solves this completely — giving you instant 1-second fuse protection while your employer or CPO billing works without a hitch.
Built-In Smart Billing Pass-Through
Connect your chargers through GEMS to The Charge Grid, E-Flux, LastMileSolutions, or any corporate CPO platform. RFID charge cards and automatic reimbursement flow straight through while GEMS keeps your building fuses safe — even offline.
Direct High-Speed Charger Control
On our flagship RAEDIAN NEO, NEX, NORA & Gemini chargers (plus Alfen, KEBA, Peblar, and more), GEMS adjusts charging speed every single second over your local network while the charger stays directly connected to your billing provider.
Three Smart Charging Modes for Home & Business
Manage a single home charger or up to 64 parking bays with Equal Share (fair split across all cars), Priority Queue (executives or departing fleet vans first), or Solar First (100% free green surplus charging).
