Battery (ESS) dashboard

The Battery dashboard displays the state and performance of the energy storage system.

In the top-right corner, you can choose your preferred view: each battery separately or all batteries combined.

What this dashboard shows

• State of charge (SOC) gauge and bars indicating charge and discharge energy, daily cycles, and available energy.

• Battery traffic: stacked bar chart showing charging and discharging power, with a line representing SOC.

• Component details: each battery module, such as CBMS1 and CBMS2, with SOC, status, dischargeable energy, current, voltage, and temperature. The DC converter section shows inverter power, voltage, and current.

Frequently asked questions

Where can I find how much energy is left in my battery?

The battery dashboard shows the current state of charge (SOC) as a percentage and, where available, the amount of energy still available for discharge in kWh, both as an overall figure and per individual battery unit. The EMS dashboard also displays a summary of the current SOC.

To understand what the algorithm is currently deciding for a specific device, open the EMS dashboard. It shows the algorithm's active decision per device, for example whether a battery is being charged, discharged, or held in standby, and why.

Why is my battery still charging or discharging when it should not be?

Several factors can cause small unexpected power flows:

• A configured grey zone around zero kW within which the system does not actively correct.

• Measurement tolerances and a small delay between measuring and adjusting.

• Other active strategies, such as imbalance trading signals or a manual override.

• Loads behind your main meter that are not controlled by the EMS.

If the behaviour is persistent and significant, check the active strategy settings and any manual overrides under Devices.

Does the battery still work when the controller is offline?

When the EMS controller is offline, the battery is no longer under active smart control by Voltmasters. Some devices have a built-in fallback mode, for example a fixed charge power for an EV charger, but price optimisation, grid protection, and strategy-based control are not available while the controller is disconnected. Smart control resumes automatically once the controller comes back online.
