Solar & Inverters

Battery Storage (BESS)

EV Charging Depots

Heat Pumps (SG Ready)

Six Intelligent Modules Working in Harmony

1. Solar & Inverters Smart zero-export feed-in regulation, automatic curtailment during negative electricity prices, and maximum self-consumption.	2. Battery Storage (BESS) Automated state-of-charge scheduling for commercial and residential batteries: price arbitrage, backup reserve, and peak shaving.	3. EV Charging Depots Dynamic power distribution across dozens of AC and DC chargers based on real-time building load and vehicle departure times.
4. Heat Pumps & HVAC SG Ready integration converts excess solar generation or low-priced grid electricity into thermal storage automatically.	5. Real-Time Monitoring Live power-flow telemetry, 15-minute peak analytics, CO₂ savings reports, and financial ROI tracking via web and mobile.	6. Meteodata & AI Forecasting Hyper-local weather irradiance modeling and historical load profiling proactively optimize daily battery and EV schedules.

Multi-Site Cloud Dashboard

LAYER 1 • ON-SITE DIN-RAIL HARDWARE

GRID-EMS — Real-Time On-Site Intelligence

Installed directly on your electrical DIN rail, our industrial edge controller protects your main grid connection 24/7 with zero cloud dependency.

✓	Sub-second Dynamic Load Balancing (DLB) across AC charging hubs and high-power DC chargers.
✓	Multi-protocol hardware I/O: Modbus RTU (RS485), Modbus TCP, SunSpec, P1/DSMR, MQTT & SG Ready.
✓	Autonomous offline fail-safe: uninterrupted main breaker protection during internet outages.
✓	Direct BESS & PV dispatch: battery charge/discharge control and automatic negative-price curtailment.

LAYER 2 • CENTRAL CLOUD PLATFORM

GRID-EMS-SERVER — Fleet Orchestration & Arbitrage

Our cloud platform connects directly to wholesale energy markets, coordinates multi-site depots, and forecasts solar yield and load with AI.

✓	EPEX Spot Day-Ahead & Intraday: automated daily charge/discharge schedules calculated at 13:00.
✓	Multi-site fleet aggregation: unified enterprise dashboard across all offices, depots, and BESS assets.

✓	Enterprise connectivity: secure Over-The-Air (OTA) firmware updates, REST APIs, and live WebSockets.

Why Clients Choose GEMS — Immediate Operational & Financial ROI

1. Dynamic Tariffs Trading

Automatically charge batteries and EVs when EPEX wholesale prices are low or negative, and discharge stored power during expensive peak hours.

● Day-ahead & intraday optimization
● Negative feed-in price protection

2. Peak Shaving & Grid Capacity

Avoid high capacity tariffs and expensive grid connection upgrades. GEMS injects battery power within milliseconds when demand spikes.

● Cut peak capacity charges by up to 40%
● Run more chargers on existing grid capacity

3. Smart EV & Depot Charging

Switch between 100% Solar-Only charging and departure-time fleet scheduling with priority boost for VIP and commercial fleet vehicles.

● Priority VIP & fleet departure queues
● Active 3-phase load balancing
