显示余电利用建议
- There is enough annual surplus to consider smart daytime charging for an electric vehicle.
- Use a timer or energy manager to heat domestic water during solar production peaks.
- Schedule the dishwasher, washing machine, dryer, pool pump or cooling for the strongest solar hours.
- A battery may shift part of the daytime surplus to the evening; compare its added cost before deciding.
何时使用
使用场景
- 在请求报价之前准备好问题。
