C. Grid monitoring
Continuous monitoring of the grid voltage to ensure the voltage and frequency values stay within operating
limits.
D. Inverter internal device protection
The inverter has all kinds of internal protection to protect the device inside when grid or input DC side have
abnormal situation.
E. Ground fault protection
This inverter must be used with panels connected with “floating” connections, that is, with positive and negative
terminals without ground connections. An advanced ground fault protection circuit continuously monitors the
ground connection and disconnects the inverter when a ground fault is detected. The ground fault condition is
indicated by a red LED on the front panel.

3.1 Installation Process
Outlines of this chapter
This topic describes how to install the SOFAR 10-20KTL.
Installation notes
Caution
Danger
Attention
Do not install the SOFAR 10-20KTL on flammable building materials.
Do not store the SOFAR 10-20KTL in areas with flammable or explosive
materials.
Do not install the SOFAR 10-20KTL in places prone to body contact because the
SOFAR 10-20KTL shelf and heat sinks become hot during the SOFAR 10-
20KTL operation.
Take the SOFAR 10-20KTL weight into consideration when transporting and
moving the SOFAR 10-20KTL.
Install the SOFAR 10-20KTL in an appropriate position and surface.
Assign at least two persons to install the SOFAR 10-20KTL.
This topic describes the process for installing the SOFAR 10-20KTL.
3.2 Checking Before Installation
Before unpacking, check that the packing materials are intact. After unpacking, check that the
deliverables are complete and intact.
3.3 Tools
Prepare tools required for installation and electrical connections.
3.4 Determining the Installation Position
Determine an appropriate position for installing the SOFAR 10-20KTL.
3.5 Moving the SOFAR 10-20KTL
This topic describes how to move the SOFAR 10-20KTL to the installation position horizontally.
3.6 Installing the SOFAR 10-20KTL
Before installing the SOFAR 10-20KTL, secure the shipped rear panel to the wall. Then secure
the SOFAR 10-20KTL to the rear panel by using hexagon screws.
