Chapter 6. OFF-GRID installation
6. OFF-GRID installation
This chapter applies to the following systems:
• PS100-WT + BAT
• PS100-PV + BAT
• PS100-H + BAT
The above inverters, after retrofitting with the PS100-INT module, can additionally work in mode 2: auto on-
off-grid.
DO NOT MAKE ANY CONNECTIONS WHEN AN ELECTRICAL VOLTAGE IS
PROVIDED TO THE INVERTER!
THE VOLTAGE SOURCE MAY BE BETWEEN OTHER:
PV PANELS, GENERATOR, ELECTRIC NETWORK, BATTERIES, EXTERNAL
CONTROL CIRCUITS.
INSTALLATION, MAINTENANCE AND MAINTENANCE OF INVERTER TECHNICAL
PERFORMANCE MAY ONLY BE CARRIED OUT BY A PERSON WHO HAVE
APPROPRIATE QUALIFICATIONS AND HAVE SUFFICIENT KNOWLEDGE IN THE
OPERATION OF ELECTRICAL INSTALLATIONS.
INCORRECT INSTALLATION AND MAINTENANCE OF THE TECHNICAL
PERFORMANCE OF THE APPLIANCE MAY CAUSE DANGER TO LIFE, HUMAN
HEALTH, LOSS OF PROPERTY, OR IRREVERSIBLE DAMAGE TO THE
APPLIANCE.
There are two types of entries from the side of the renewable electricity source:
• AC input: synchronous generator input (wind farm, hydro power plant), used in PS100-WT +
BAT, PS100-H + BAT systems;
• DC input: PV solar panel input used in PS100-PV + BAT, PS100-H + BAT systems.
Depending on the type of inverter you have, installation and commissioning should be carried out in
accordance with the following sections (6.1, 6.2, 6.3).
After their completion, the inverter will be ready for autonomous operation without user intervention.
The user can only obtain information on the current status of the device via communication buses (RS-485,
Ethernet) or directly from the panel. Detailed description of communication configuration with inverter is in
chapter 11.
ATTENTION:
1. When installing the inverter, remember that the electrical circuit from the generator or PV panel side
must be galvanically separated from the grid. Additional measuring circuits connected between the
generator and inverter must also comply with this principle. Otherwise, the system may malfunction
and even damage, which will not be covered by the warranty.
2. In off-grid mode, consider the need to connect the PE conductor to the N terminal of the inverter - to
provide protection against electric shock.
