5. Start Up
This chapter provides instructions to ensure a safe start-up of the THEIA HE-t inverter.
5.1. How to Start Up
A minimum available voltage of 230 V
DC
and a DC power of >7 W
DC
is required before the
inverter starts feeding power to the grid.
AC Side
• Turn ON the AC circuit breaker(s).
DC Side
• Turn ON the DC switch(es).
5.2. Initial Start
When the inverter is started for the first time, an installation menu is automatically displayed
to enable the configuration of certain critical values and operational settings.
5.2.1. Customizing the Inverter Settings
Single Inverter
• When both the AC circuit breaker and the DC switch are turned ON and the inverter is
supplied with enough power, the installation menu is displayed on the LCD screen.
Multiple Inverters Connected
• Connect all inverters via the CAN bus so that configuring one inverter configures all
inverters. The Start Up can then be carried out on any inverter, and if configured as the
master inverter all the configuration settings of time, date, language and grid settings will
be transferred to all the other inverters on the network (slaves).
• Each inverter is automatically assigned an ID number from the master during Start Up.
