Our Solutions
Precision-engineered solutions for solar monitoring, power control, and seamless communication.
PC-based SCADA
Plant-wide supervision & Control for large ground-mounted solar plants — live data, historical trends, alerts, reports and fault analysis in one on-premise dashboard, with remote monitoring built in.
Plant-wide supervision from a single PC-based workstation, with live data alongside full historical trend history for every connected device.
Supervise and control plant equipment remotely, with the same on/off and time-based control tools used across eSenZ hardware.
Built-in control tools for PV-DG synchronisation, zero export and export limits, alongside time-based operation.
Configurable threshold alerts with automated reports and fault analysis to reduce downtime across large sites.
The same SCADA runs Zero Export (ZED), DG Synch, DG Isolation, Demand Control and BESS charge / discharge, and monitors inverters, import / export meters, DG, ACDB, transformer oil & winding temperature and weather stations (RMS) — all from one screen.

ZED + DG Synch
Zero Export Device
& PV-DG Synchronisation
ZED intelligently curtails excess solar generation to prevent reverse flow into the grid, while DG Synch seamlessly synchronises solar inverters with diesel generators — reducing fuel consumption and operational costs.
Real-time monitoring and dynamic throttling of inverter output to maintain zero net export to the grid.
Smart loading algorithm maximises solar usage while DG sets handle the balance — cutting diesel consumption by up to 40%.
Run both together on one site: export stays at zero on-grid, and generation still shifts smartly to DG when solar can't cover the load.
IP65-protected enclosure engineered to withstand heat, dust, and heavy rainfall in demanding outdoor environments.
Real-time status on the eSenZ portal with configurable threshold alerts via SMS and email.

BESS
Monitoring and control for battery energy storage systems. Track battery status, coordinate charging and discharging with solar and the grid, and manage everything remotely from one dashboard.
Live state of charge, voltage, current and temperature from the BMS and PCS inverter, alongside the rest of your plant.
Charge from surplus solar and discharge when it matters most, coordinated with solar generation and the grid.
Connects to PCS inverters, BMS units and energy meters over RS485 Modbus, using the same eSenZ hardware as the rest of your site.
Runs together with zero export, demand control and DG synch, so storage, solar, grid and generator work as one system.
