3.1.2. Operation
The inverter must only be operated in accordance with the information in this User Manual.
DANGER: Operate the inverter as specified in this User Manual!
The THEIA HE-t is a grid interactive inverter and must be used exclusively for its
designed purpose, which is to convert PV-generated DC electricity into AC
electricity to feed into the grid.
• The inverter must be operated in its original and technically intact condition without any
unauthorized modifications.
• Always keep the values of operation within the limits given in the technical specifications,
due to the risk of possible inverter damage.
CAUTION: Keep the voltage and current within the specified limits!
The voltage generated by the PV modules is inversely proportional to the
temperature: at lower temperatures the PV voltage increases from the nameplate
rating and at higher temperatures the PV voltage decreases from the nameplate
rating.
• Unintended use may damage the inverter or other electrical equipment, may interfere with
the operation of the inverter, or it can, at worst, cause injury or death to persons operating
and maintaining the inverter.
• Misuse involves ignoring the instructions and information in this User Manual and also not
performing regular maintenance work.
