Brand: eSolutions

Model: DPM 2.0

Type: User manual

eSolutions DPM 2.0 is a device that can be used to configure advanced functionalities of your eProWallbox, such as DPM (Dynamic Power Management), load unbalance, and energy meter configuration. With DPM, you can set a contractual power limit to ensure that your EV charging does not exceed your grid connection capacity. It also enables load unbalance settings to manage the distribution of current among phases and avoid overloading.
