4.1 USER INTERFACE
NOTE. The GP-SB-PWM includes an LCD screen with 4 mechanical buttons that act as navigation keys to control the display.
4.2 MENU OPERATION
Three menus are implemented in the display: status, settings, and history. At power up, the controller turns on within the status menu. The different menus can then be accessed by pressing the Enter key as shown below.
This leads to the status menu number one. Pressing the up and down keys allows navigation to the other menus as shown below. Menu 1 is for status, Menu 2 for settings and 3 for history.
4.3 STATUS PARAMETERS
The status menu is entered by the controller at power-up. It is used to display key parameters as well as warnings and faults. Three displays are automatically scrolled through as shown below. The up ▲ and down ▼ keys can also be used to manually scroll through these. This auto scroll can be disabled using option #5 in the settings menu.
The first display shows battery voltage and current. The second shows solar open circuit voltage. The third shows the controller temperature.
When the charging is disabled through the settings, the solar voltage display will show the following menu display to indicate this was set intentionally by the user.
4.4 HISTORICAL PARAMETERS
The GP-SB-PWM historical amp-hour charging can be accessed by entering menu number 3.
This section allows the user to review the previous usage for different settings based on the selected timeframes, as explained on the following pages.
NOTE. These calculations do not reflect the entirety of the power generation of the solar panel(s), but the power put back into the battery to maintain the state of charge.
4.5 CURRENT DERATING
The GP-SB-PWM constantly monitors the internal temperature to ensure it does not exceed UL limits. In applications that require full output current in high ambient temperatures, the solar controller starts limiting the current delivered to the battery to keep the PCB temperature within UL specifications.
4.6 BLUETOOTH® WIRELESS TECHNOLOGY
This section is for the GP-SB-PWM-30-BT Controller only!
Note. The GP-SB-PWM-30BT comes with Bluetooth® Low Energy wireless technology for live status monitoring and settings configuration on mobile devices. It works together with the Go Power! Connect App, available for both Android and iOS devices.
Download and install the Go Power! Connect app, which is available on the Google Play store for Android devices and the App Store for iOS devices.
4.6.1 PAIRING
When connecting for the first time, pairing between the charge controller and the mobile device is required. Also ensure your mobile device’s Bluetooth® communication function is enabled. You will see the Bluetooth® symbol present on your status bar if so. Open the app, and the Main page will prompt you to select devices.
Once the solar controller is powered up, please select the charge controller in the Device Selection main page of the Go Power! Connect app. The App will prompt you to name the device for reconnection next time the app is used.
4.6.2 APP USAGE
Upon initial connection you will load into the charge controller’s main status screen. You will be able to see the SoC, Battery Type, Voltage, Current of the controller. In addition to the main screen, there are two additional tabs “History & Alerts” to track the Ah usage and any important faults/alerts that may occur.
Please disconnect from the controller when you are done using the app. This helps mitigate any future connection issues. To disconnect the controller, press the “Go Power” Logo located at the top left of the app and click the red DISCONNECT button. The same button is found at the bottom of the Status page.
4.6.3 APP SETTINGS
In addition to the charge controller settings, you will be able to set the temperature unit, reboot, force float & absorption and reset the “Ah” history.
If you need to reset the controller to its factory settings it is located at the bottom of the APP settings page.
For custom batteries, you will be able to set custom parameters to ensure the proper custom battery profile and float, equalization and absorption voltages are optimal.
