How is the battery used in the Ferroamp system?

There are several uses for a battery in the EnergyHub system. You can charge the battery from both a photovoltaic system and from the grid, and use the battery to increase your own use of solar electricity, to cut power peaks, to avoid electricity price spikes and to sell support services to the grid.

There are three ways to control the battery.

Make your own settings and schedule in EnergyCloud
Automated control with FerroAI
External control

1. Make your own settings and schedule in EnergyCloud

Go to: EnergyCloud/System settings/System Configuration

In EnergyCloud, you can choose between three different operational settings that can also be used for scheduling:

Increase self consumption of solar electricity
Charge the battery during the day and to discharge it when the solar panels stop producing. You save money by using more of the self-produced electricity within the property than when you sell it online, because in addition to the electricity price, you also avoid paying taxes and transmission fees for the electricity you would otherwise have.

Peak shaving

The battery is allowed to charge when electricity consumption in the property is low and is then able to discharge when electricity use is high, thus cutting the power peaks. Used especially if you pay power tariffs. Can also be used to limit the size of the connection to the mains.

Manual

In manual mode, you can start in and discharge with even power manually. For example, can be used in a schedule if you know between which hours you want to charge or discharge the battery.

Scheduling
Switch between different operating modes based on the day of the week and time of day. For example, the battery can be charged from the electricity grid at night when electricity prices are generally lower and discharged in the morning when prices are higher. It can then be charged during the day when there is a surplus of solar power production and then discharged again in the evening.

2. Automated control with FerroAI

FerroAI provides automated AI-based control of the entire Ferroamp system. FerroAI performs calculations based on your unique conditions and combines increased self-use and spot price optimization with cutting power peaks to always give you as big savings as possible.

3. External control

The control of the battery can also be done via external programs through our open API. The battery can also be transferred to a service provider for support services, for example. Please note that Ferroamp cannot provide support in terms of control from external applications or other service providers.

How do I set up the battery to increase self consumption of solar energy?

There are different ways to optimize the self-use of solar electricity.

FerroAI
Smart control that combines self-use with other functions in the system to lower your total costs.
The “Self consumption” preset
The system charges the battery when there is a surplus of solar power, and discharges as soon as the production does not cover the house’s consumption.

FerroAI
Activated via the app.

The Self Consumption Preset

Go to: EnergyCloud/ System Settings/ System configuration/ Temporary Settings/ Self Consumption

Select “Self Consumption” under the tab “Operating settings”.
This will set the system to an Export Threshold of 0 and an Import Threshold of 0. This means that the battery will start charging as soon as there is a surplus of solar power in the system and start discharging as soon as there is a shortfall, and the system will automatically set the recommended settings for the battery’s “Battery Power” and also the “Battery State of Charge”.
Then click “Update” to save the settings.
When the “Success” message appears, “Self Consumption” is active.

NOTE
If the solar power is not produced in the Ferroamp plant but from an external inverter and only charging with solar power is desired, the operating setting can be set to “Peak Shaving” with “Limit value for electricity network import” and “Limit value for electricity network export” set to 0 kW. This means that the battery will be charged when electricity starts to be exported from the property and discharged when the property starts importing electricity from the electricity grid.

How do I set up the battery for peak shaving?

There are several different ways to cut power peaks.

FerroAI
Smart control that sets optimized limit values and combines cutting of power peaks with other functions in the system to reduce your total costs.
The “Peak shaving” preset
You can set the level at which you want the battery to go in and cut power peaks and below which power output the battery should be charged.

FerroAI
FerroAI is activated via the app.

The “Peak Shaving” Preset

Go to: EnergyCloud/ System Settings/ System configuration/ Temporary Settings/ Peak shaving

Select “Peak Shaving” under the tab “Operational Settings”. The system will automatically set the recommended settings for the battery’s “Battery Power” and also the “Battery Level (SOC)”.
Set the threshold for “Electricity network import threshold” and “Benchmarkelectricity network export”.

In the example above, we have set “Grid import threshold” to 3000 W, this means that the battery will discharge when the import from the electricity grid exceeds 3000W. “Grid Export Threshold” is set to 2000 W, which means that the system is allowed to import extra power to charge the battery when the import from the electricity grid goes below 2000 W.

NOTE:
In this case, “Grid import threshold” is set so that the electricity network tariff stays below 3 kW. If we have a consumption of 5kW for a short time, the system will import 3 kW from the grid and discharge 2 kW from the battery provided that there is energy in the battery to discharge.

NOTE
If we have a “Grid Export Threshold” of 2 kW and the property draws 1kW, the battery will be allowed to import 1 kW from the grid to charge the battery. This is so that there is always available energy in the battery to handle the power peaks.

3. After this, check that “Solar production (PV)” and “Phase balancing (ACE)” are turned on if the system has solar power production integrated into the Ferroamp system or is in need of phase balancing.

4. Then click “Update” to save/write the settings to the EnergyHub. When the “Success” message is printed, the system has received the settings.

RECOMMENDATION!

Look at historical power data in the Power view when setting the thresholds to optimize battery usage.

The threshold for electricity network exports should be set so that the battery is allowed to be charged regularly, i.e. set the value so that there are a number of hours during the day when the power consumption is lower.

The threshold for electricity grid imports should be set so that the battery’s maximum power (kW) is able to cut the peaks and so that we have enough energy (kWh) available in our battery to cut the entire peak.

EXAMPLE:
The battery must cut power peaks to remain on the main fuse at 16 A:

We have a battery with a storage capacity of 10 kWh and a maximum power of 4 kW
We have a basic consumption of around 6 kW, but for 3 hours every day, the consumption rises to 13 kW. This corresponds to about 19 A per phase and means that we would need a fuse level of 20A
To ensure that the battery is allowed to charge, we set the threshold for electricity grid exports to 8 kW
In order to remain on a 16 A fuse, we set the threshold for electricity grid imports to 10 kW. We will then cut 3 kW (3kW<4kW) for 3 hours, which corresponds to an amount of energy of 9 kWh (9kWh<10 kWh).
Our power peak is now 10 kW, which corresponds to about 15 A per phase.

How do I use Manual mode to charge or discharge my battery?

Go to: EnergyCloud/ System settings/ System configuration/ Temporary Settings/ Manual

Operation setting Manual can be used when you want to take full control of how much power you charge or discharge your battery, this can be useful during e.g. commissioning to balance the battery and make sure that all cells are evenly placed over the entire battery.

1. Select “Manual” under the “Operation settings” tab: In manual operation settings, you can set a fixed “Power reference” with which you want your battery to charge or discharge, regardless of whether it is with import from the electricity grid or solar power production. The settings you can set are “OFF”, “Charge” or “Discharge“.

In this example, we have set the battery to “Charge” with 1000W.

Then click “Update” to save the settings.
When the “Succeeded” message is printed, the system has received the settings, “Manual” is now active. The system will charge or discharge your battery using the power you set under “Power reference”.

How do I do spot price optimization?

Spot price optimisation means that the battery is charged in and out taking into account the current spot price on the market. The battery is charged when electricity is cheap and discharges when electricity is expensive. In the Ferroamp system, spot price optimisation takes place as part of the automatic control in FerroAI.

What settings should the battery have during the winter?

If your battery has the setting “Self consumption”, there is a risk that it will remain idle during the winter as there is rarely a surplus of solar power to charge the battery with. To avoid this, you should choose one of the following options:

Enable FerroAI for automatic battery usage optimization
Select the “Peak shaving” preset
Schedule battery charging and discharging
