Build your solar plan — no payment until you approve
Configure solarOptimise 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.
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.
Monitor real-time output from your PV system. Know exactly how much you're generating at every moment.
Automate when your battery stores solar and when it releases energy — aligned to tariff windows and forecast generation.
Charge your EV when solar surplus is available — avoiding expensive peak grid imports while keeping your vehicle ready.
Track NEM exports and grid imports. Minimise exports and maximise direct self-consumption for better financial returns.
Every feature is designed to increase the value you extract from your solar and battery investment.
Track solar generation, battery state-of-charge, grid import/export, and total consumption in a unified dashboard — updated every few seconds.
Charge batteries during off-peak tariff windows or when solar is generating. Discharge automatically during peak demand hours to minimise grid costs.
Schedule EV charging to coincide with peak solar generation — charge your vehicle with solar surplus rather than expensive peak-rate grid electricity.
Automated scheduling aligned to TNB Time-of-Use tariff windows — shift loads and battery dispatch to minimise your peak-rate electricity spend.
AI uses weather forecasts to anticipate solar generation tomorrow, pre-charging batteries from the grid if a cloudy day is expected at low off-peak rates.
Receive real-time alerts for inverter faults, grid outages, battery low-state warnings, or unusual consumption spikes — on iOS and Android.
Smart energy management scales from residential HEMS to full commercial EMS with demand management.
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.
For facilities with 50kWp+ solar. Adds demand management, peak shaving, and BMS integration to reduce maximum demand charges on commercial TNB tariffs.

Go beyond basic solar monitoring — extract maximum value from every kilowatt-hour your system generates.
Use more of your own solar generation directly. Reduce exports to the grid at low NEM rates — keeping more solar value inside your home or building.
Smart battery dispatch cuts your consumption during expensive peak-tariff windows. Business customers can see significant monthly bill reductions.
Optimised charge/discharge cycling avoids damaging deep discharges and overcharges — extending your battery system's operational lifespan by years.

Common questions from homeowners and facility managers evaluating HEMS and EMS solutions.
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.
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 low NEM rates. 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.
Trexon's smart energy management solutions integrate with the major inverter brands available in Malaysia — Huawei FusionSolar, SolarEdge, Enphase Enlighten, and Sungrow iSolarCloud. Each platform has its own monitoring portal and API, which we connect to a unified dashboard. For battery systems, compatibility depends on the specific inverter-battery pairing. We recommend confirming compatibility before installation.
TNB's Time-of-Use (TOU) tariff charges different rates for electricity consumed at different times of day — peak rates during morning and evening demand periods, off-peak rates overnight. TOU currently applies to medium-voltage commercial and industrial accounts (Tariff C2/E2 and above). For these customers, smart energy management can significantly reduce bills by shifting battery discharge to peak periods and charging overnight at off-peak rates.
Yes. Smart EV charging integration ensures your vehicle charges preferentially when solar generation exceeds household consumption — effectively charging your EV with free 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.
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.
