1.Brand: PowMr

2.Product Model: Z10

3. There are no serviceable parts for this controller. Do NOT disassemble or attempt to repair the


4.Make sure all connections going into and from the controller are tight.

5.Do NOT allow water to enter the controller,please install in the room.if installed outside,please

keep the environment dry,avoid directly sunlight.

6.NEVER connect the solar panel array to the controller without a battery. Battery must be

connected first.

7.DO NOT connect any inverter or battery charger into the load terminal of the charge controller.

8.Refer to the technical specification for the maximum current value and maximum wire size

passing over the controller. Make sure your total input voltage and power does not exceed.

9.This controller only suitable for Solar Photovoltaic panel, Never connect other power source to

this controller.

Installation Instructions

Tools required for installation: Screwdriver, Meter



1. Choose the installation location - Install the charge controller vertically in a place where it will not be exposed to direct sunlight and not high temperature and do not install in location where water can enter the controller.

2. Please confirm environment that sufficient ventilation is possible.

2. Clearance check - At least 6 inches (150 mm) clearance must be left above and below the controller in order to wire.

3. Cut the wall - The width of the part to cut the wall is slightly larger than the inside width of the controller and the depth must be 1.7 inches (43 mm) or more.

4. please select correct screw to fix the controller on the wall or other platform.

5. Please reserve enough space between the wall and controller,to allow for cooling and cable connection.
