CE Mark
UK CA Mark
Information important for the protection of property. Violation of this type
of information may cause damage and loss of property.
Useful additional information or “Tips and Tricks” on specific subjects.
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.
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.

2.2 Electrical system design
For safety reasons, the use of a DC switch is recommended. Between the
PV modules and the power modules may be mandatory in some countrie.
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 Rayleigh Instruments when dimensioning a photovoltaic system.

2) The DC cable connected correctly to the inverter DC side through DC circuit breaker, please be attention to the cable
connected to the two string correctly and it’s polarity;
3) The unused terminals are covered.
Starting the inverter:
Close the DC and AC circuit breaker;
If the solar panels provide enough energy, the power module will work and the LCD panel will be lit;
In case you are starting the inverter for the first time, the inverter needs to be commissioned. Commissioning is
described on page 17,chapter 4.3.
Then the inverter will turn into self-check mode and the LCD panel will display the remaining time of connect simultaneously;
After the inverter turn into normal mode, it feed electrical energy into grid, and LCD panel will display the generated
electrical energy.
As long as the inverter works, it will automatically track the maximum power point to absorb the maximum energy from
solar. When night comes, the irradiance is not strong enough to provide energy, the inverter will power off automatically.
When the next day comes, the input voltage reaches the start value, it will start again automatically.
