Analyse your energy systems in detail

A dedicated place per installation

Open an installation and choose Analyses. Everything you need to investigate its behaviour is in one place.

Data and control side by side

See not only what a battery or inverter did, but also which signal was behind it.

Ready-made or build your own

Start from a view, or add your own charts and compare periods.

New: download data

Take the data into your own tools

Use the download button below each chart to get the data for your own analysis or reporting.

New: one chart per question

Ask your question, see the answer straight away

Generation, battery, grid and consumption used to share one large chart, where you had to find the answer yourself. Now we've split that up: each chart answers one question.

Heatmap of the battery's state of charge per hour over a month
Battery

Why was the battery empty before the evening peak?

See how full the battery was for every hour, the whole month in one view.

State of charge
Day-ahead market price with the battery's charging and discharging below it
Trading

Does the battery charge when electricity is cheap?

See the market price next to the moments of charging and discharging.

Trading
Grid power and battery power against the threshold and connection capacity
Grid connection

When do we get close to the threshold?

See the power on the connection next to your threshold, and what the battery did.

Grid loadPeak shaving
Power per phase with the imbalance against the threshold below it
Phases

Is the load evenly spread across the phases?

See the power per phase and when the imbalance went above the threshold.

Phase balance
Curtailment chart with generation, feed-in, export limit and estimated curtailed energy
Solar

How much generation was held back, and why?

See when generation was limited and what caused it.

CurtailmentPer hour
Energy mix per quarter hour with own generation and the origin of grid electricity
Energy mix

How green was the electricity we used?

See how much came from your own generation and what the grid share was made up of.

Energy mix
Charging power of the charging site with the number of active charge points
Charging site

Are all charge points being used?

See the total charging power and how many charge points were active at the same time.

Charging sitePer charge point
Energy signature: average power per day against the outdoor temperature
Heat pump

Does the heat pump use more than expected?

See consumption against the outdoor temperature, over a whole year.

The battery's setpoint next to its measured power
Control

Does the battery follow the control signal?

See the setpoint next to the battery's measured power.
