New Intelligent Actuator Lowers Investments in and Operational Costs of your Solar Tracker

Share Article

The new LA36 actuator from LINAK with embedded MODBUS communication lowers operational costs and investments by reducing the use of signal cables and interface boxes significantly.

Linear Actuator LA36

As the first actuator manufacturer LINAK is embedding MODBUS, which is a well-known and reliable technology for transferring data, directly in the LA36 actuator.

LINAK actuators help enhance the energy generation of solar panels by adjusting them so that they follow the sun during the day.

As the first actuator manufacturer LINAK is embedding MODBUS, which is a well-known and reliable technology for transferring data, directly in the LA36 actuator.

The embedded MODBUS communication has 3 benefits:

  • Lower investments
  • Lower operational/maintenance costs
  • Longer lifetime

Lower investments:
Embedded MODBUS in the actuator ensures that several trackers can be connected by a single data line, thereby eliminating the need for many signal cables so that only two cables are needed – one for MODBUS and one for power. Furthermore, the system is less complex and it only needs one central controller to program and control a string. By controlling all solar trackers from a central point it is possible to save the cost of interface boxes.

Lower operational/maintenance costs:
MODBUS communication reduces the resources needed for operation and maintenance. Due to a standard communication language it is easier to program your solar applications and it takes less time to install MODBUS.

The actuator is equipped with standard M12 connectors for easy interfacing with standard bus cables.
The LA36 actuator with embedded MODBUS communication can be adjusted according to speed (10-100%) and stroke length. This makes it possible to improve the functionality of the final applications.

Preventive maintenance such as temperature readings or current measurement inside the actuator can predict if something is wrong with the actuator or the processor. It is also possible to remotely monitor the installation by use of Ethernet-BUS gateway.

Longer lifetime:
The LA36 actuator with embedded MODBUS communication has a longer lifetime because of its electronic overload protection and lower speed that reduces wear of mechanical parts. Additionally, it has a non-contact potentiometer and an adjustable current limiter.

LA36 actuator:
The LA36 actuator is the most solid and powerful actuator designed to operate under extreme conditions. The actuator has a maximum thrust of up to 10,000 Newton. It is the obvious choice for large solar panels because of its very high self-locking ability.
