Installation Instructions for the Hybrid E5 Battery Storage System EU V1 EN 2018-09-17
Regulations in your country may require that
a mains-connected battery storage system
in isolated operation (TN system) implement
a connection between the neutral conductor
(simulated star point) and the protective earth
conductor (main grounding rail).
The same may be required for battery storage
systems intended to run exclusively in isolated
operation.
In both cases, contact Delta customer service
before
you decide on a technical solution.
► Always follow the specific regulations of your country
or region.
► Always follow the specific regulations of your energy
provider.
► Install all the stipulated safety and protective devices
(such as automatic circuit breakers and/or surge pro-
tection devices).
► Protect the inverter with a suitable upstream 32 A
circuit breaker.
Residual current circuit breaker
Due to its design, the inverter cannot supply the mains
with DC residual current. This means that the inverter
meets the requirements of DIN VDE 0100-712.
Possible error events were assessed by Delta in accor-
dance with the current installation standards. The assess-
ments showed that no hazards arise from operating the
inverter in combination with an upstream, type A residual
current circuit breaker (FI circuit breaker, RCD). There is
no need to use a type B residual current circuit breaker.
Minimum tripping current of the type A resid-
ual current circuit breaker
≥100 mA
The required tripping current of the residual cur-
rent circuit breaker depends first and foremost
on the quality of the solar modules, the size
of the PV system, and the ambient conditions
(e.g. humidity). The tripping current must not,
however, be less than the specified minimum
tripping current.
Integrated residual current monitoring unit
The integrated, universal current-sensitive residual cur-
rent monitoring unit (RCMU) is certified in accordance with
VDE 0126 1-1/A1:2012-02 §6.6.2.
Requirements for mains voltage
The mains voltage range is 230 VAC ± 20%.
Cable requirements
The AC plug provided with the inverter has the following
technical characteristics:
Plug type
Amphenol C16-3
Cable diameter
11 ... 20 mm
Wire cross-section
2.5 / 4 / 6 mm
2
Recommended tightening
torque for clamping screws ≥0.7 Nm
The AC plug can only be used with a flexible copper cable.
For wire cross-sections from 11 to 13 mm, deenergize the
lead just behind the plug.
Consider the following factors when calculating the cable
diameter:
● Cable material
● Temperature conditions
● Cable length
● Installation type
● Voltage drop
● Loss of power in the cable
► Always follow the installation regulations for AC
cables applicable in your country.
► France: Follow the installation regulations of UTE 15-
712-1. This standard contains the requirements for
minimum cable diameters and for avoiding overheat-
ing due to high currents.
► Germany: Follow the installation regulations of
VDE 0100-712. This standard contains the require-
ments for minimum cable diameters and for avoiding
overheating due to high currents.
Connecting the power meter
The installation location of the power meter depends on
the features of the specific site. Installation on a DIN rail in
the meter cabinet is preferable.
The power meter can alternatively be installed in a sepa-
rate box inside of which the power meter is protected from
touch and external influences. A DIN rail is included in the
scope of supply.
The current clamps (1 for P1E, 3 for P3E) must be laid
around the phase cable (L for P1E; L1, L2 and L3 for P3E).
Always comply with applicable regulations when installing
the power meter.
