Battery 8760s
8760 exports contain hour-by-hour simulation data for one year for your design (24*365=8760). To generate a Battery 8760, click the export button in the upper-right, and then "BESS + Solar 8760." You will have the option to either download separate 8760s (one for each field) or combined 8760s, which is the default and combines all fields into a single CSV file. The primary fields to look at are
Electricity to grid from battery AC: AC export from the battery system only.Electricity to grid from system AC: AC export from the solar to the grid only. We aggregate these columns to get the total system export to the grid in the BESS pdf report.
Column definitions
| Column | Name | Unit | Description |
|---|---|---|---|
| A | Battery state of charge | % | The remaining capacity of the battery at a given time, expressed as a percentage of its total capacity. |
| B | Battery voltage | V | The electrical potential difference between the positive and negative terminals of the battery. |
| C | Battery current | A | The rate of electric charge flowing into or out of the battery. Positive values indicate charging, negative values indicate discharging. |
| D | Battery temperature | °C | The internal temperature of the battery, which can affect its performance and lifespan. |
| E | Electricity from battery to system AC | kW | The amount of AC power being supplied from the battery to the system's AC bus. |
| F | Electricity from battery to system DC | kW | The amount of DC power being supplied from the battery to the system's DC bus. |
| G | Electricity to/from grid AC | kW | The amount of AC power being exchanged with the grid. Positive values indicate power being drawn from the grid, negative values indicate power being sent to the grid. |
| H | Electricity to load from system AC | kW | The amount of AC power being supplied from the system to the electrical loads. |
| I | Electricity to load from battery AC | kW | The amount of AC power being supplied directly from the battery to the electrical loads. |
| J | Electricity to load from grid AC | kW | The amount of AC power being supplied from the grid to the electrical loads. |
| K | Electricity to battery from system AC | kW | The amount of AC power being used to charge the battery from the system's AC bus. |
| L | Electricity to battery from system DC | kW | The amount of DC power being used to charge the battery from the system's DC bus. |
| M | Electricity to battery from grid AC | kW | The amount of AC power being used to charge the battery from the grid. |
| N | Electricity to grid from system AC | kW | The amount of AC power being sent from the system to the grid. |
| O | Electricity to grid from battery AC | kW | The amount of AC power being sent from the battery to the grid. |
| P | Power produced without the battery or curtailed | kW | The total amount of power that would have been produced by the system if the battery were not present, or if production was not curtailed. |
