Instructions on setting up your My MidNite account can be found on the above webpage.
All communications between the Classic and MidNiteSolar’s server are encrypted using a strong session-
based algorithm. To respect your privacy, however, it is required that you manually enable this feature if
you’d like to use it.
In order to enable the web access feature:
 Press Main Menu
 Scroll to NET menu and press the Enter button
 Using the soft keys, navigate to the ADVANCEDmenu (NET→NEXT→ADVANCED)
 The Web Access option should be highlighted.
 Use the up/down keys to enable or disable the feature.
 After saving the change you will need to reboot the Classic by removing PV power and Battery power with
the 2 disconnects and waiting for the screen to go dark. Wait 30 seconds and re apply PV and Battery
power.
Note that the Web Access selection indicates the current setting of the feature: i.e. ENABLED means the
feature is currently in operation.
Note also that you will need the values MA and DI handyin order to create an account on the My MidNite
web site. This unique number pair identifies your particular classic to our server and helps to prevent
malicious users from trying to access your Classic. The DI or (Device Id) is different than your Unit’s
Serial Number.
Local Network
Note that your Classic identifies itself by name to DHCP-enabled routers as ―Classic‖. There is facility to
change the name of a given Classic via the local and web-based interfaces as well as using third-party
MODBUS software packages.
Advanced
The Classic advertises it’s address every 10 seconds using the UDP protocol. Advanced users and
programmers may use this feature to identify Classics on their network.
Positive Ground systems
When installing the Classic in a positive ground systems there are a few extra steps that need to be taken.
The Ground fault jumper needs to be removed, and ground fault needs to be disabled in the menu. Refer to
page Disabling GFPon page 24for instructions on doing this.
The overcurrent protection needs to be done a little differently as well. The input and output breakers need
to be double pole breakers. Battery negative and positive conductor both need to be protected. Refer to
Classic Breaker Sizing on Page 70.
IMPORTANT: Do not connect both positive battery and positive PV input to ground. One or the
other positive (normally battery +) but not both, otherwise, the Classic input and output will be
shorted.
