Selection of battery system
To select a battery system, proceed as follows:
Selection of the battery system
Selection Battery system
Use the Companies and Model drop-down menus to select the desired battery system. With the button
you get detailed information about the selected battery system. Alternatively, click the 
button to access the database of battery systems. The desired battery system can also be selected there.If the desired battery system does not exist in the database, you can create your own data records and use them.

Battery system information
Informations Battery system
| Parameter | Description |
|---|---|
| Installed power | Rated power of the battery inverter |
| Charging performance (U0) | Required charging power for boost charging of the batteries in kW. Results from the storage capacity of the battery and the boost parameters (U0 charge) in the battery charging strategy |
| Battery | Rated power of battery inverter in kW |
| Peak load | Maximum power of all consumers in kW |
| Usable battery energy | Calculated from the battery voltage DC, the battery capacity C10 and the usable battery charge range (Maximum SOC - Minimum SOC) |
| Average consumption at night | Recommended size of HTW Berlin [1] |
| Battery | Usable battery energy in kWh |
| Average consumption per 24h | Daily average value of all consumers in kWh |
| Maximum consumption per 24h | Maximum daily consumption of all consumers in kWh |
The electrical charge stored in a battery (galvanic cell) is called capacity.
