1 About this manual
General Notes
Eversol is a transformerless solar inverter with two MPP trackers. It converts the
direct current (DC) from a photo-voltaic (PV) generator to grid-compliant alternating
current (AC) and feeds it into the grid.
1.1 Validity
This manual describes the mounting, installation, commissioning and maintenance of
the following Zeversolar inverters: Eversol-TLC 10K/15K/17K/20K.
Observe all documentation that accompanies the inverter. Keep them in a convenient
place and available at all times.
1.2 Target group
This manual is for qualified electricians only who must perform the tasks exactly as
described.

12 Installation and operating instructions
6Avoid exposing the inverter to direct sunlight, rain and snow to ensure optimal
operation and extend service life.
Recommend to mount an awning above the inverter or mount the inverter
under the shaded site of the building.
7The mounting method, location and surface must be suitable for the inverter's
weight and dimensions.
8If mounted in a residential area, we recommend mounting the inverter on a solid
surface. Plasterboard and similar materials are not recommended due to
audible vibrations when in use.

Danger to life due to fire or explosion!

14 Installation and operating instructions
4.3 Mounting the inverter with the wall bracket
CAUTION!
Risk of injury due to the heavy weight of the inverter!
•When mounting, two persons are needed, take into account that the inverter
weighs approx. 48kg.
Mounting procedures:
1Use the wall bracket as a drilling template
and mark the positions of the drill holes, Drill
5 holes required using a drill with 10mm bit.
The holes must be about 70mm deep. keep
the drill vertical to the wall, and hold the drill
steady to avoid tilted holes.
WARNING!
Risk of the inverter falling off and injuring the installer!
•Before inserting wall anchors, measure the depth and distance of the holes.
•If the measured values don’t fulfill the mounting requirement, redrill the holes.
2Fix the wall bracket to the wall with 5 wall anchors and bolts delivered with the
inverter.

CAUTION!
Risk of injury due to electric shock!
•The external protective earthing conductor is connected to the
inverter’s protective earthing terminal through an AC connector,
make sure the connection is reliable.
•When connecting, connect the AC connector first to ensure the
inverter earthing and then connect the DC inputs.
•When disconnecting, disconnect the DC inputs first and then
disconnect the AC connector.
•Do not, under any circumstances, connect the DC inputs when the AC
connector is unplugged.
5 Electrical connection
5.1 Safety
WARNING!
Risk of injury due to electric shock!
•The inverter must be installed only by trained and authorized electricians.
•All electrical installations must be done in accordance with the National Wiring
Rules standards and local code.

18 Installation and operating instructions
5.2 System layout of units without integrated DC-switch
Local standards or codes may require that PV systems are fitted with an external
DC-switch on the DC side. The DC-switch must be able to safely disconnect the
open-circuit voltage of the PV array plus a safety reserve of 20%.
Install a DC-switch to each PV string to isolate the DC side of the inverter.
We recommend the following electrical connection:
