cesses for the inverters SM330TS-SV, SM360TS-SV (TS-SV inverter) and their control
unit TS-SV Master Control Unit (MCU).
1.2 Target group
This operating manual is written for the operator of the PV system and the qualied
electrician.
1.3 Where to keep this manual
The system operator must ensure that this operating manual is available to those respon-
sible for the system at all times. If this original document is lost, an up-to-date version of
the operating manual can be downloaded from our website (www.solarmax.com).

2 Safety instructions
DANGER
■ In daylight the PV generator supplies the inverter with a dangerously high DC
voltage.
■ SolarMax inverters and accessories may only be installed or opened by qualied
electricians who have completely read and understood this instruction manual in
advance.
■ Only qualied electricians who have already completely read and understood this
instruction manual in advance may install and open SolarMax inverters.
■ Ignoring the installation and safety instructions shall cancel any and all warranty
and liability claims.
■ Touching live parts is life-threatening.
■ The inverters and accessories must not be opened at any time during operation.
■ Before the inverter or the MCU is opened, the DC and AC feed lines must be dis-
connected according to the instructions and secured against being reconnected
accidentally.
■ After disconnecting the inverter wait at least 5 minutes before opening the device
to permit internal capacitors to discharge.

53
3 Description
All SolarMax inverters work completely automatically. The DC and AC power switches
(Q4-Q6 and Q1-Q3) as well as the main switch (Q7) are always on during normal opera-
tion. The inverter starts when there is enough input power and continues to operate until
the available input power from the PV generator drops below the necessary minimum.
The inverter is operated using the external master control unit (MCU). The MCU controls
the connected inverters and is also the communications and user interface.
3.2 Operating elements
The following section describes the operating elements of the TS-SV inverter and the
master control unit (MCU).

4 Operation
The inverter is operated using the external MCU. The MCU allows all the connected invert-
ers to be operated simultaneously, only the DC and AC power switches must be operated
directly on the respective inverter.
For all other functions described below the MCU is the shared interface for all the con-
nected inverters.
4.1 How the main switch works
When you switch off the main switch Q7, turning it to the OFF position, the inverter opens
the contacts of the AC protections K1, K2 and K3. This disconnects the inverter from the
mains.
DANGER
If you switch the main switch Q7 to the OFF position, the inverter’s components are
still live! This includes the 3 power units and the lters on the input end!
4.2 How the DC and AC power switches work
The DC power switches Q4, Q5 and Q6 are used to connect or disconnect the direct
current of the PV plant to the inverter. The AC power switches Q1, Q2 and Q3 connect or
disconnect the inverter to or from the mains. The DC as well as the AC power switches
are equipped with thermomagnetic overcurrent fuses.
DANGER
Even when the DC and AC power switches are switched off, the connections for the DC
and AC feed lines in the inverter are still live!

57
4.3 Switching on the inverter
Procedure
Action Reaction
1. Switch off main switch Q7
(to “OFF” position)
2. Switch on DC power switch Q4, Q5 & Q6
(to “ON” position)
The graphics display is activated after a
maximum of 20 seconds (if there is enough
sunlight).
3. Switch on AC power switch Q1, Q2 & Q3
(to “ON” position)
4. Switch on main switch Q7
(to “ON” position)
After several seconds the Overview menu is
displayed. The message “Startup....” appears
in the “Status” line. The status LED blinks
green.
When the connected inverters have been
started up and are feeding power into the
mains, indicates the device status “Mains
operation”. The status LED glows green.
NOTE
■ When the inverters are commissioned the “Initial Setup” menu appears rst,
during subsequent start-ups the “Overview” menu; see the installation manual.
■ If several inverters are connected to one MCU steps 2 and 3 must be performed
for each inverter before the main switch Q7 switches on the whole system (step 3).

58
en
4.4 Switching off the inverter
DANGER
■ Even when the inverter is switched off, the connections for the DC and AC feed
lines in the inverter remain live!
■ Before the inverter or the MCU is opened, the DC and AC feed lines must be dis-
connected according to the instructions and secured against being reconnected
accidentally.
■ After disconnecting the inverter wait at least 5 minutes before opening the device
to permit internal capacitors to discharge.
Procedure
Action Reaction
1. Switch off main switch Q7
(to “OFF” position)
Message on the graphics display is: “Main
switch off”. The device disconnects from the
mains.
2. Switch off AC power switch Q1, Q2 & Q3
(to “OFF” position)
3. Switch off DC power switch Q4, Q5 & Q6
(to “OFF” position)
After a short time the graphics display of the
MCU is shut down.
NOTE
Steps 2 and 3 must be repeated for each inverter connected to the MCU.

59
4.5 Operating the graphics display
The graphics display on the front of the MCU shows the system dimensions, status infor-
mation and the malfunction messages of the connected inverters. The display allows you
to learn the current device status, access the integrated data logger and enter various
system settings. Navigate the various menus using the three push-buttons under the
display.
Since the MCU is supplied with power both from the DC end and the AC end, it is also
possible to use the MCU functions at night or when the DC end is shut down. However,
the inverters connected to the MCU only deliver data and measured values if the inverters
are in operation (when there is enough power from the DC end).
To the left of the graphics display there is a status LED indicating the device status, see
7.1 “Status messages and status LED”.
4.5.1 Menu button symbols
With the help of the symbols shown here you can navigate the various menus and func-
tions visible in the display. The current button function changes from one menu to the
next, corresponding to the symbol appearing directly over the button:
