Hardware Installation

Note: Prior to use, it is recommended to write down the factory default password for this device. The password can be found on the sticker located under the SolarPoint cover.
Pole Mounting

1. Attach the 1U rackmount bracket (included) to either side of the SolarSwitch..

2. Mount the SolarSwitch to one of the side rails in your rack.

3. Remove the four-pin connector from the battery terminal block.

4. Crimp a ferrule on one end of the wire.

5. Insert the crimped wire into the appropriate slot on the four-pin connector. Using a flathead screwdriver, secure the wire to the connector by tightening the screw until it stops.

6. Repeat steps four and five until the connector is fully occupied with all four wires.

7. Connect wires and NTC Thermistor to batteries.
   Note: The battery will not be charged without connecting the NTC Thermistor. Note: Use SLA, AGM or Gel Lead batteries.

8. Attach the NTC and battery cable using the four-pin connector.

9. Attach the PV panel cables.

Connecting Ethernet

1. Connect Ethernet cable(s) to the Ethernet port(s).
   Note: PoE is disabled by default and can be enabled using the configuration interface.

Configuration

Connect to your LAN via Ethernet or Wi-Fi.
Ethernet
If connected to the LAN via Ethernet, the SolarPoint will attempt to obtain an IP address automatically from a DHCP server.  Use the Ubiquiti Device Discovery Tool to determine its IP address.
If there is no DHCP server on the LAN, the SolarPoint will fall back to the following IP address: 192.168.1.20
Wi-Fi
Connect your notebook, tablet, or smartphone to the SolarPoint SSID named SolarPoint-XYZ, where XYZ represents the last three characters in the MAC address of the SolarPoint.
Once connected to your wireless network, the SolarPoint will use the following IP address: 192.168.153.1

User Interface

1. Launch a web browser and enter the IP address of the SolarPoint. Press Enter (PC) or Return (Mac).
2. Enter ubnt in the Username field.
3. Enter the password in the Password field (the password can be found on the sticker located under the port cover.)
4. Click Set Device Location to set the location for your solar system installation.
5. Click Power on the Settings screen and fill out the battery and solar panel information.

Enabling PoE

To enable PoE on the SolarPoint:

1.  Click Output on the Settings screen.
2.  Click the toggle button from OFF to ON, for each port you want to enable.
