Intended Product Usage
To prevent personal injury or property
damage, the inverter must only be installed,
wired, connected, commissioned, maintained
and serviced by qualified personnel:
•
Trained in installing electrical devices.
•
Familiar with all applicable laws, regulations,
standards and codes for electrical devices.
•
Familiar with safety requirements and safety-related
guidelines for electrical devices.
•
Familiar with work protection laws and regulations.
•
Using the appropriate personal protective equipment.
Power Storage 4.0, 5.0 and 6.0 are stationary 3-phase
string inverters with integrated battery charger. They
convert direct current (DC) supplied by the PV array and
the battery into alternating current (AC), which can be fed
into the electricity grid.
They are not designed for any other application or
connection to other devices.
Any use that differs from or goes beyond the intended
usage is considered misuse. RCT Power GmbH shall not
be liable for any damage resulting from misuse.
Any misuse will terminate warranty, guarantee and
general liability of the manufacturer.

[3] Electrical Connection
[3.1] Overview Connection Parts
Fig. 2
[3.2] AC Connection
Risk of death or injury due to electric shock!
While the inverter is connected to grid (AC
voltage source), to PV array which is exposed to
sunlight (DC voltage source) or to the battery
(DC voltage source), high voltage is present in
cables and inner parts of inverter.
•
Important: All voltage sources (DC / PV-generator,
DC / battery and AC / utility grid) must be disabled
before any electrical work.
To disable PV-generator DC voltage connection turn DC
switch to 0-position and wait 10 minutes before
continuing.
To disable AC voltage connection turn off AC switch,
main breaker or fuse. Make sure, other persons don’t
switch back.
Do not enable voltage connections until work is finished.
•
To disable DC battery voltage connection both voltage
sources (DC / PV-generator and AC / utility grid)
must be disabled.
•
During AC connection: Do not exchange L, N and PE
wires!
•
Make sure other persons keep away during electrical
work.
Risk of death or injury due to electric
arc!
Disconnecting DC plugs under load can
cause electric arcs.
Risk of damage due to improper
installation and operation or misuse.
•
Contact local utility company or grid operator
before connecting inverter to grid.
•
Provide for an AC disconnection device
(typical miniature circuit breaker 3 pole 6kA,
B-characteristic 16A).
•
If required in country or installation, install a
residual-current device (RCD), or residualcurrent circuit breaker (RCCB).
•
Inverter contains no owner serviceable parts.
Contact local authorized personnel for service.
•
Do not remove name plate.
•
Only RCT Power certified batteries complying
with the demands of the certain region are
allowed to be used.

[7] Commissioning
Ensure proper mechanical an electrical installation before commissioning the solar inverter.
Check the cables to ensure, that they are in sound condition.
Always disconnect the mains connection first by switching off the corresponding mains fuse and
before disconnecting the solar generator side by opening the DC load break switch.
The DC-connectors on the solar generator side must not be disconnected under load. First turn the DC
load break switch to position 0.

Establish grid connection via the external circuit breaker.
2
Switch on the solar generator voltage by closing the DC load break switch
(position 1). The solar inverter starts operating, when the input voltage
level and power is adequate.
Display will switch on and show norm „Factory defaults“.
[7.2] Access to the inverter
The Solar Inverter is equipped with an internal Wi-Fi unit. To set up Solar inverter you need to
access via Wi-Fi due to the suitable Android APP.
The Android APP is the central user interface for commissioning.
It ensures easy data collection and troubleshooting.
Obtaining Android App: Go to Google Play Store, search for “RCT Power App”, and install.
Step

several hours.
(When calibrating, power may be used out from
the grid to speed up the process if the power is
insufficient)
When calibration is complete, the system
automatically switches to compensation mode.
[8] How to switch off the system
Step
Description
