Description
Converting excess solar generation into hot water thermal storage.
SAJ eManager is an intelligent residential Home Energy Management System (HEMS) gateway with SG Ready heat pump control and dynamic tariff optimization, engineered to coordinate rooftop solar, battery storage, and home heating into an automated self-consumption ecosystem.
SG Ready Heat Pump Integration
Automatically signals heat pumps to boost thermal storage buffers when rooftop solar exceeds household baselines.
Dynamic Spot-Market Tariff Arbitrage
Automates battery charging during negative or low-cost hourly electricity windows and discharges during peak hours.
Unified Whole-Home Energy Orchestration
Synchronizes SAJ solar inverters, battery stacks, and EV chargers into a single optimized self-consumption schedule.
Compact DIN-Rail Breaker Panel Mounting
Installs cleanly on standard 35 mm DIN rails inside domestic distribution boards with minimal standby draw.
More product details
Exporting surplus solar for low feed-in tariffs wastes valuable energy. The SAJ eManager features SG Ready dry-contact relay outputs that command heat pumps to raise buffer tank temperatures when solar generation exceeds household electricity demands.
- Direct dry-contact relay interface compatible with all standard European SG Ready heat pump controllers.
- Modulates thermal buffer setpoints dynamically based on real-time solar surplus and battery state-of-charge.
- Maximizes annual solar self-consumption by storing surplus energy in thermal hot water buffers.
Automated battery charging during negative and off-peak price hours.
European electricity markets increasingly adopt dynamic hourly spot pricing. The eManager downloads 24-hour day-ahead pricing automatically to schedule charging. Automatically charges the home battery during negative or low-cost night pricing windows. Discharges stored energy during expensive morning and evening utility peak demand windows. Real-time energy flow tracking, cost analytics, and custom appliance automation managed via eSolar portal.
Fits standard residential DIN rails
The compact modular housing clips into standard distribution boards. Removable connector blocks make cabinet wiring straightforward.
Talks to the elekeeper 5.0 platform
Operating metrics stream directly to the mobile app and web portal. Storage dispatch and controllable loads share one interface.
Runs intelligent energy scheduling for loads
Energy scheduling routes surplus electricity into flexible appliances. Dedicated automation rules align demand with generation.

What is "SG Ready" and how does the gateway connect to my heat pump?
Standardized 2-wire dry contact that tells the heat pump when solar surplus is available. "SG Ready" (Smart Grid Ready) is the European industrial standard for smart heat pumps. The eManager connects via a simple 2-wire low-voltage control cable to the heat pump’s SG Ready digital inputs, signaling the compressor to ramp up thermal storage whenever rooftop solar generation exceeds domestic demand.
