1.1 Symbols for hazard statements
DANGER!
This shows dangerous situations.
If the guidelines are not followed, these situations will result in death, serious personal injury, and equipment
damage or destruction.
WARNING
This shows potentially dangerous situations.
If the guidelines are not followed, these situations could result in death, serious personal injury, and equipment
damage or destruction.
CAUTION
This shows low level risk situation.
If the guidelines are not followed, these situations could result in minor or moderate injury.
NOTICE
This shows an important notice
Make sure to read this information.
1.2 About the operator's manual
This document gives the necessary information to operate the controller.
CAUTION
Installation errors
Read this document before working with the controller. Failure to do this may result in human injury or damage
to the equipment.
Intended users of the operator's manual
The operator's manual is for the operator that uses the controller regularly.
The manual describes the LEDs, buttons and screens on the controller, alarm handling, and the logs menu.
OPERATOR'S MANUAL 4189341347A EN Page 3 of 32

1.3 Warnings and safety
Factory settings
The controller is delivered pre-programmed from the factory with a set of default settings. These settings are based on
typical values and may not be correct for your system. You must therefore check all parameters before using the controller.
Data security
To minimise the risk of data security breaches:
• As far as possible, avoid exposing controllers and controller networks to public networks and the Internet.
• Use additional security layers like a VPN for remote access, and install firewall mechanisms.
• Restrict access to authorised persons.
1.4 Legal information
Third party equipment
DEIF takes no responsibility for the installation or operation of any third party equipment, including the genset. Contact the
genset company if you have any doubt about how to install or operate the genset.
Warranty
NOTICE
Warranty
The controller is not to be opened by unauthorised personnel. If opened anyway, the warranty will be lost.

2. About ASC 150 Solar
2.1 About controller operation
The ASC 150 Solar controller controls and protects a photovoltaic system  with up to 32 inverters. You can add the
controller to an existing plant as a single controller setup, or use it with other DEIF controllers in a power/energy
management system.
You can easily control the system from the display. The display can show your configured application with a simple diagram
that gives you information about the power sources and breaker feedback.
2.2 Typical application examples
2.2.1 Single controller (without power management)
In single-controller applications, one ASC 150 Solar controller can control one photovoltaic system  one photovoltaic
breaker  and one mains breaker.
Application for one ASC 150 Solar controller
This example shows one ASC 150 Solar controller in a mains power export application. The ASC controls the PVS, the PVB,
and the mains breaker. The ASC controller gets power measurements and breaker positions from the mains.
More information
See Single-controller applications in the ASC 150 Solar Designer's handbook for variations on this controller
arrangement.
2.2.2 With power management
The ASC 150 Solar controller also works in DEIF power management applications, where the controller communicates with
other DEIF controllers. The ASC 150 Solar controller can control the PV system  and the PV breaker  in these
applications.

6082 LED mimic Standard
Guided
Standard
The control buttons and LEDs are shown.
If you the stop the photovoltaic system  the PVS symbols are
shown in red.
Guided
Active control buttons, LEDs, and the PVS symbols are shown,
inactive are not shown.
Example: The controller is in  mode, and the PVS is not
operating. The only possible action is to start the PVS, or open the
mains breaker. Therefore, only the start button, the red PVS
symbols, and the button to open the mains breaker are shown.
All Mimic settings
The breaker symbol is shown in red:
• Breaker position failure
• Breaker close failure
The breaker symbol flashes green:
• The controller is synchronising
• The controller is de-loading
3.2 Running modes
The controller has two running modes:
•AUTO : The controller operates automatically and the operator cannot start sequences manually.
•SEMI-AUTO : The operator must start all sequences. You can do this with the buttons, Modbus commands, or digital
inputs.
SEMI-AUTO mode
Use external signals to operate the controller in  mode.
Give an external signal with:
1. Buttons on the display
2. Digital inputs*
OPERATOR'S MANUAL 4189341347A EN Page 9 of 32

3. Modbus commands
NOTE * The controller has a limited number of digital inputs. See Digital inputs in the ASC 150 Solar Designer's
handbook for availability.
Commands in SEMI-AUTO mode
Command Description
Start The start sequence for the photovoltaic system  is started. The breaker must be
closed before you can start the system.
Stop The PVS is stopped.
Close the PV breaker  The controller closes the PV breaker if there is voltage on the busbar.
Open the PV breaker  The controller ramps down and opens the PV breaker at the breaker open point.
Close the mains breaker
In applications with a PV system, a mains, and external gensets, it is only possible to
close the mains breaker if:
• The genset breaker(s) is open
• The PV breaker is closed.
The PV breaker must be closed to make sure there is no voltage on the busbar before
you close the mains breaker.
Open the mains breaker The controller opens the mains breaker instantly.

3.4 Easy connect
You can use Easy connect in your energy management system if the application consists of only genset or ASC Solar
controllers. Easy connect is a fast and easy way to add more controllers to a new or existing application. Easy connect
commands normally come from the display, but they can also be sent from  and Modbus.
More information
See Easy connect in the ASC 150 Solar Designer's handbook for how to activate and use Easy connect.

4. Modes of operation
Operate the ASC Solar controller in AUTO mode or  mode. In AUTO mode, the controller automatically starts
and stops the PV, and controls the power automatically. In  mode, the operator or an external signal can open
and close the PV breaker, and start the system.
4.1 Island operation
The PV system  is non-grid forming. The system can supply the load in island mode if there is a grid-forming source in
the application, for example, a genset. Use the ASC Solar controller to maintain a minimum genset load and support the
generator with reactive load when needed.
