Electrical installation
Electrical connections
»
There is a risk of electric shock in the vicinity of the
electrical connections of the solar module.
»
Modules can be connected in series and / or in parallel
to obtain the required electrical output, provided the
information in the product specifications is followed.
»
Use only modules of the same type in a combined circuit.
»
Do not disconnect modules under electrical load. There
is a risk of electric shock in the vicinity of the connecting
elements of the solar modules.
»
If you connect the module in series or in parallel (e.g.
when using extension cables), the connection of all
modules should be identical (with the appropriate plug
from the same manufacturer).
»
Ensure the firm connection between the plugs. They
audibly click into place when they are connected.
PLANNING / ELECTRICAL DESIGN
e.ISP – Energetica
Integrated Shadow Protection
All Energetica modules have intelligent electronics integrated
in the module called e.ISP (Energetica Integrated Shadow
Protection).
Thanks to their 80 percent lower power loss compared to
conventional Schottky diodes in standard panels, a noticeable
increase in energy yield is achieved. At the same time, e.ISP
represents a much more effective protection of the module
in the event of unforeseen shading and thus optimizes the
power loss of the modules in the event of shading.
IMPORTANT SAFETY INFORMATION !!
Correct interconnection of the module strings
In order to reduce high voltages caused by indirect
lightning strikes, the area of all conductor loops must be
as small as possible. Before commissioning the generator,
check the correct interconnection.
If the measured open circuit voltage deviates from the
specification, there is a connection error. Pay attention to
correct polarity.
Return currents
Please note the limit values for reverse current resistance
of our photovoltaic modules according to the data sheet. In
some cases, inverters can cause very high reverse currents
in the module field due to their input capacities, which can
destroy the photovoltaic modules or lead to personal injury
and property damage.
When selecting an inverter, please ensure that the
inverters used have reverse current protection!
Your inverter manufacturer can provide you with information
on this.
If this is not the case, it is imperative to provide an external
device adapted to the output, which reliably protects the
module strings from excessively high reverse currents (e.g.
blocking diode with the appropriate output). In this context,
please observe the manufacturer's installation instructions.
