Can this charging controller be used indoors?

It is generally not recommended to use indoors. Because it is a device used to connect photovoltaic (PV) panels and lithium batteries (LifePo4), PV panels usually need to be placed outdoors to receive sunlight to generate electricity, and may generate certain heat during charging, which may pose safety risks and malfunction when used indoors.

What are the requirements for PV panels of different powers?

This charging controller has a certain power processing capability. When connecting the PV panel, the maximum power of the PV panel should be within its acceptable range.

What affects the charging speed of the battery?

The charging speed is mainly controlled by the charging controller based on the current state of the battery (such as battery level, voltage, etc.) and the output power of the PV panel. Meanwhile, the output power of the PV panel also affects the charging speed.
