10.1.2.4 Battery
(stand-alone) System > Technical data > Battery
The type and number of batteries are defined on the "Battery" page.
-> How to proceed:
1. Open a Battery from the database.
If the desired battery is not available there, it must be entered via the menu Databases >
Battery.
2. The Number and Number in series must match the nominal DC voltage of the
inverter and the MPP trackers or the module voltages.
- Enter the Number of batteries.
- Enter the Number in series.
3. a) System with Back-up generator:
In Charge condition at simulation start, enter the value 50 %.
Calculating the suitable start condition is not possible.
4. a) System Without back-up generator:
Select the option Preliminary simulation to establish start condition (The Charge
condition at simulation start is then ignored).
An initial year is simulated and then December 31 used as the start value for
January 1 of the next simulation year.
This prevents the energy balance of the simulation being displaced by a large
deviation in the start value of the battery charge condition after the simulation.
