# Battery Settings

Setting battery-related parameters can optimize battery performance, extend battery life, and achieve intelligent charging and discharging strategies.

## Charging Source Prority

* <mark style="color:blue;">The battery acquires power according to the set order.</mark>
* <mark style="color:blue;">By default priority, PV is placed before Grid, PV solar charges the battery first, Grid supplements the remaining charge.</mark>
* <mark style="color:blue;">In the negative electricity price scenario, Grid can be adjusted to be before PV.</mark>

## Battery Discharging Prority

### &#x20;C\&I Energy Storage Power Station

When Battery Preheating Scheduling is set to![](/files/86PcBgATdAL6GTQzNOda), you need to select the preheating mode.

#### Depends on System (Automatic)

Automatic mode is supported only when the power station is in TOU scheduling mode.
