1.Introduction
1.1 Introduction
This manual describes solar inverters: NAC4K-DS/NAC5K-DS/NAC6K-DS/NAC7K-DS/NAC8K-DS.
These inverters are transformerless based inverter.
Please read the safety instructions in this manual first. Throughout the manual it is assumed that the reader is
familiar with AC and DC installations and knows the rules and regulations for electrical equipment and for
connecting it to the utility AC grid. It is especially important to be familiar with the general safety rules for
working with electrical equipment.
1.2 Applied designations
Throughout the manual important information is shown at different levels depending on the character of the
information, as shown here:
Safety information important for human safety. Violation of warnings may result in injury to
persons or death.
Danger of high voltage and electric shock!
Signals danger due to electrical shock and indicates the time (5 minutes) to allow after the
inverter has been turned off and disconnected to ensure safety in any installation operation.
Danger of hot surface!
Product should not be disposed as normal household waste.
CE Mark
RoHS

1.3 Important safety information
Read this before installing, operating or maintaining the inverter.
1.4 System sizing
When dimensioning a photovoltaic system, it must be ensured that the open circuit voltage
of the PV string never exceeds the maximum permissible input voltage of 600V DC. The PV
string open circuit voltage during parallel string operation is 550V. Higher voltages may
result in permanent damage to the inverter.
The selection of PV string output should be based on the optimum utilization of the invested capital compared
to the expected annual energy yield from the system. This optimization depends on local weather conditions
and should be considered in each individual case.
The inverter incorporates an input power limiting device, which automatically keeps the power at levels that are
safe for the inverter. The limitation depends mainly on internal and ambient temperatures. The limitation is
calculated continuously and always allows the maximum possible amount of energy to be produced.
Please use the tool supplied by Renac Power when dimensioning a photovoltaic system.
Before installation:
Check for damage to inverter and packaging. If you are in doubt, please contact your
supplier before installing the inverter. Check the voltages of the solar modules and make
sure they are within the limits of the inverter specifications before connecting them to the
inverter.
Installation:
Only trained and authorized personnel familiar with local electrical codes may install the
inverter. For optimum safety, please follow the steps described in this manual. Keep in mind
that the inverter has two voltage carrying sides, the PV input and the AC grid.
Disconnecting the inverter:
Always disconnect the AC line first! Afterwards disconnect the PV lines. Note that the
inverter can still be charged with very high voltages at hazardous levels even when it is
disconnected from grid and solar modules. Wait at least 5 min. before proceeding, after
having disconnected from grid and PV panels.
Operating the inverter:
Before connecting the AC grid to the inverter, make sure that the installation cover is
mounted again. The inverter must not be open during operation.
Maintenance and modification:
Only authorized personnel are allowed to repair or modify the inverter. To ensure optimum
safety for user and environment, only the original spare parts available from your supplier
should be used.
Functional safety parameters:
Unauthorized changes of functional safety parameters may cause injury or accidents to
people or inverter. Additionally it will lead to the cancelling of all inverter operating approval
certificates.

Warning！
Before installation and maintenance, AC and DC side doesn’t carry electricity, but if DC side
is just disconnected, capacitance still contains electricity, so please wait for at least 5
minutes to ensure the capacitors completely release the energy and inverter is not
electrified.
Note！
Inverters must be installed by qualified person.
