Model your project savings and peak-demand reduction
Calculate ROISmart Energy Management Malaysia
Optimise your solar, battery, and grid usage in real time. Smart energy management coordinates every energy flow in your home or business — so you use more of what you generate and pay less for what you import.
What Is Smart Energy Management?
A standard solar system generates electricity and either powers your home or exports to the grid. Smart energy management goes further — it coordinates every energy flow intelligently, in real time.
A Home Energy Management System (HEMS) acts as the brain of your energy setup. It monitors solar generation, battery charge levels, grid pricing, EV charging status, and appliance consumption simultaneously — then makes automated decisions to maximise your self-consumption and minimise what you pay TNB.
For businesses, an Energy Management System (EMS) adds demand management and peak shaving — critical for reducing maximum demand charges on commercial TNB tariffs.
Solar Generation
Monitor real-time output from your PV system. Know exactly how much you're generating at every moment.
Battery Charge / Discharge
Automate when your battery stores solar and when it releases energy — aligned to tariff windows and forecast generation.
EV Charging
Charge your EV when solar surplus is available — avoiding expensive peak grid imports while keeping your vehicle ready.
Grid Import / Export
Track Solar ATAP exports and grid imports. Minimise exports and maximise direct self-consumption for better financial returns.
Key Features
Every feature is designed to increase the value you extract from your solar and battery investment.
Real-Time Monitoring Dashboard
Track solar generation, battery state-of-charge, grid import/export, and total consumption in a unified dashboard — updated every few seconds.
Automatic Battery Scheduling
Charge batteries during off-peak tariff windows or when solar is generating. Discharge automatically during peak demand hours to minimise grid costs.
EV Smart Charging
Schedule EV charging to coincide with peak solar generation — charge your vehicle with solar surplus rather than expensive peak-rate grid electricity.
TOU Tariff Optimisation
Automated scheduling aligned to TNB Time-of-Use tariff windows — shift loads and battery dispatch to minimise your peak-rate electricity spend.
Weather-Based Forecasting
Some inverter apps and hybrid inverter/battery systems can schedule battery charging around forecast solar output and off-peak rates; available features depend on the inverter and battery model.
Mobile App Alerts
Receive real-time alerts for inverter faults, grid outages, battery low-state warnings, or unusual consumption spikes — on iOS and Android.
For Homes and Businesses
Smart energy management scales from residential HEMS to full commercial EMS with demand management.
Home HEMS
Ideal for homes with 5–15kWp solar and battery storage. Coordinates solar, battery, EV charger, and high-load appliances to minimise grid imports and electricity bills.
- Monitor solar generation in real time
- Automatic battery charge/discharge scheduling
- EV smart charging from solar surplus
- Mobile app with alerts and daily reports
- Solar ATAP export tracking and self-consumption ratio
- Weather forecast integration for pre-charging
Business EMS
For facilities with 50kWp+ solar. Adds demand management, peak shaving, and BMS integration to reduce maximum demand charges on commercial TNB tariffs.
- Maximum demand monitoring and peak shaving
- TOU tariff-aligned battery dispatch
- Multi-site dashboard and reporting
- BMS (Building Management System) integration
- Automated demand response alerts
- ESG carbon tracking and export for reporting

Why Smart Energy Management Pays Off
Go beyond basic solar monitoring — extract maximum value from every kilowatt-hour your system generates.
Maximise Self-Consumption
Use more of your own solar generation directly. Reduce exports to the grid at the lower Solar ATAP export rate — keeping more solar value inside your home or building.
Lower TOU Bills
Smart battery dispatch cuts your consumption during expensive peak-tariff windows. Business customers can see significant monthly bill reductions.
Extend Battery Life
Optimised charge/discharge cycling helps avoid deep discharges and overcharges, which supports battery longevity.
Carbon Tracking
Monitor your real-time carbon intensity and cumulative CO2 avoided. Export data for ESG reporting and sustainability disclosures.
Frequently Asked Questions: Smart Energy Management Malaysia
Common questions from homeowners and facility managers evaluating HEMS and EMS solutions.
What is a Home Energy Management System (HEMS)?
A Home Energy Management System (HEMS) is a software and hardware platform that coordinates all energy flows in your home — solar generation, battery charge/discharge cycles, EV charging, and grid import/export. Rather than managing each system independently, HEMS uses real-time data and automated scheduling to maximise solar self-consumption, minimise grid purchases during peak tariff periods, and extend battery life through optimised cycling.
How does smart energy management reduce my electricity bill?
Smart energy management reduces bills through three main mechanisms. First, it maximises solar self-consumption — using more of your solar generation directly rather than exporting it at the lower Solar ATAP export rate. Second, it optimises battery scheduling under TNB's Time-of-Use (TOU) tariff — charging batteries during low-tariff periods and discharging during peak hours. Third, it intelligently schedules high-load appliances (washing machines, dishwashers, EV charging) to run when solar is generating, reducing grid draw.
Does smart energy management work with any solar inverter?
Trexon's smart energy management solutions work with the inverter brands we install — Solis (SolisCloud), Huawei FusionSolar and Sungrow iSolarCloud. Each platform has its own monitoring portal; other brands are checked case by case. For battery systems, compatibility depends on the specific inverter-battery pairing. We recommend confirming compatibility before installation.
What is TOU tariff optimisation and who does it apply to?
TNB's Time-of-Use (TOU) tariff charges different rates for electricity consumed at different times of day — the peak rate applies from 2 pm to 10 pm, Monday to Friday, and off-peak applies from 10 pm to 2 pm on weekdays and all day on Saturday, Sunday and public holidays. TOU is available to medium-voltage commercial and industrial accounts on the Medium Voltage Time of Use tariff, and to high-voltage accounts on High Voltage Time of Use. A domestic time-of-use option also exists; confirm eligibility with TNB. For commercial and industrial customers on these tariffs, smart energy management can significantly reduce bills by shifting battery discharge to peak periods and charging at off-peak times.
Can smart energy management optimise my EV charging?
Yes. Smart EV charging integration ensures your vehicle charges preferentially when solar generation exceeds household consumption — effectively charging your EV with your own solar energy rather than grid electricity. For businesses with multiple EV chargers, demand management features prevent all chargers from running simultaneously at full power, avoiding peak demand charges on commercial TNB tariffs.
What size system does smart energy management suit?
Home HEMS is most beneficial for solar systems of 5 to 15kWp with battery storage, particularly households with EVs or high daytime electricity usage. Business EMS becomes highly valuable at 50kWp and above, where demand management and peak shaving can generate significant monthly savings. For very small systems without batteries, basic monitoring may suffice without full HEMS investment.
