4.4 GENERAL SAFETY AND INSTALLATION PRECAUTIONS
WARNING
Be sure that all wiring is disconnected from
any power source during the entire
installation.
CAUTION!
• Short circuiting or reversing DC polarity
may lead to damage to the Soladin, the
cabling and/or the terminal connections.
• Follow all steps of the installation
instructions in order of succession
as described.
CAUTION!
When the PV array is exposed to light, it
supplies a DC voltage to the solar inverter!
4.5 COUNTRY SUITABILITY
European countries maintain different regulations with regard
to the grid interface of solar inverters. Because of these
different regulations the Soladin must be configured at first
installation.
4.6 AC CONNECTION COMPARTMENT
The Soladin Web inverter features an AC connection
compartment with a strain relief to fit for a pvc tube or AC
cables of different diameters. This strain relief can be turned
upside down to accomodate smaller diameter cables. The
AC terminal is suitable for conductor diameters up to 4
mm2. The AC wiring has to be led through the cable gland
parts then connected according to figure 4-6.

4.7 SPECIFICATIONS OF THE PV INSTALLATION
Never connect voltages higher than specified
to the inverter, as this will cause permanent
damage to the inverter.
The inverter will automatically limit the input
current and power to its specified rating. Excess
power will not be converted.
Use of Amphenol Helios H4 connectors is
mandatory!
The table below shows the recommended DC cable cross
sections dependent on the cable lengths.

4.8 LIGHTNING PROTECTION
In a solar installation, precautions must be taken to avoid
damage from surges induced by lightning. The Soladin
inverter is equipped with class III (micro) protection.
4.9 WI-FI ROUTER
Please bear in mind you need a Wi-Fi compatible router to
be able to use IntelliWeb.
