2 Introduction

In the following system level technical description, the precise functions are explained to the
installer, as well as the user, which are required for the installation, operational start-up and han-
dling of the solar inverter.
The content of renewable energy with respect to overall power consumption worldwide is increas-
ing annually by approximately 25%. The reason for this rise can be primarily attributed to the con-
stantly increasing demand for power, the increasing interest in environmentally friendly technolo-
gies, as well as the increasing costs of non-renewable energy.
By the use of renewable energy sources, the earth‘s atmosphere can be enormously relieved of
increases in CO2 and other harmful gases which result from power generation.
The solar inverter converts direct current from the solar cells into alternating current. This enables
you to feed your self-produced solar energy into the public grid.
Thanks to e󰀩cient MPP tracking, maximum capacity utilization of the solar energy plant is en-
sured even in cases of misty and cloudy skies.
The string concept means that PV modules are always connected in series (in a string) and/or
that strings with the same voltage are connected in parallel to the solar inverter with the aim of
signicantly reducing the photovoltaic system’s cabling requirements.
The fact that the modules are connected in strings also means that the photovoltaic system can be
perfectly matched to the solar inverter’s input voltage range.
The inverter is transformerless type without galvanic isolation. Therefore, the inverter may only be
operated with ungrounded PV arrays. Furthermore, the PV array must be installed in accordance
with the NEC690.35 (Ungrounded Photovoltaic Power Systems) and the locally valid regulations for
ungrounded PV arrays. Additionally, the PV array (PV modules and cabling) must have protective
insulation and the PV modules used must be suitable for use with this inverter. PV modules with
a high capacity to ground may only be used if their coupling capacity does not excessed 1,200 nF
with 60Hz grid.
2.1 System
If a high voltage(HV) battery is connected to the Delta E series inverter, it must be ac-
tivated before use. This setting can be done in factory test or via APP after installation.
HV battery communicates with Mario E series inverter through RS485 or CAN. And the
battery must comply with the specications of UL1973.
For DC-couple system, PV panel works in MPPT mode or power reduction mode ac-
cording to system orperationa mode. And the maximum number of PV string is three.
For AC-couple system, there may be no solar module connected to Delta E series
inverter, and the PV power option will be deactivated.
The Delta E Series inverter manages battery and system energy.

2.2 Data evaluation and communication
The integrated interface, processing and communication of the device enables easy operation of
the solar inverter. Monitoring of the operational status and signaling of operational failures are capa-
ble of being called up over the interface. The data interfaces enable the downloading of data which
can be evaluated with the aid of a PC system and allow continuous recording of operating data.
The best way of accessing this functionality is via a monitoring system connected to your inverter.
2.3 Technical structure of the solar inverter
The RSD provides an automatic disconnect of residential or small commercial PV
systems, fully compliant with the Rapid Shutdown requirements of NEC 2014 Article
690.12.
Meter is used by the inverter for import / export or consumption readings, and manages
the battery charge / discharge accordingly for smart energy management applications,
for example self-consumption, zero-export or TOU. Meter reports its electricity measur-
ing value to inverter via RS485 following Modbus.
240V / 208V grid are supported, and it can be congured via APP.
A very powerful tool for monitoring, conguration or diagnosis. APP is connected to
inverter via BLE.
Delta E series can exchange with Delta cloud using gateway (Wi-Fi / Ethernet / Cellular)
which can be installed in the AC wiring box of inverter. Also, gateway can push data
directly to customer’s cloud or third-party cloud.
There are several groups of switch mounted inside Auto Transfer Switch(ATS), and it
can be used for realizing automatic transfer from grid connection mode to o󰀨 grid mode,
or from o󰀨 grid mode to grid connection mode.
The photovoltaic voltage is adjusted so that the maximum power output of the PV modules is also
achieved with di󰀨erent solar irradiation levels and temperatures (MPP-Tracking). These inverters
have quite wide MPP range of suit for variety of PV modules by a variety of manufacturers. Mea-
sures must be taken to ensure that the maximum no- load voltage is never exceeded. Please note
that the maximum no-load voltage will occur at the lowest temperatures anticipated. You will nd
more detailed information about temperature dependency in the data sheet for the PV modules.
The high-quality aluminum casing corresponds to protection degree Type 4 and is protected by an
anti-corrosion nish. The heat sink on the Delta solar and energy storage inverter
is designed in such a way that operation of the inverter is possible at ambient temperatures from
-22°F to +113°F (-30°C to +45°C) at full power and optimal e󰀩ciency for either 240 Vac or 208 Vac
AC grids.

Metal ns designed into the rear side of the inverter chassis are used to dissipate heat and protect
the unit. An internal temperature control protects the interior of the device. In case of high ambient
temperatures, the maximum transferable power is limited.
The inverter is controlled by microcontrollers which provide interface communication and the values
and messages by APP or cloud
AC grid monitoring is done by an independent dedicated micro controller set up to meet the require-
ments of UL 1741,UL1741 SA / IEEE 1547. This enables a connection of the solar inverter to the
in-house grid.
Operator protection requirements are met by electrically isolating the grid from the PV module. The
electrical isolation between the grid and the PV module is equivalent to basic insulation. Maximum
operator protection is ensured by reinforced isolation between the grid, PV modules, bettery and
accessible interfaces (display, RS485 interface ). Relevant standards concerning electromagnetic
compatibility (EMC) and safety are fullled.
The inverter is functional in grid-parallel operation exclusively. An automatically anti-islanding func-
tion, which was accepted by a certication agency, guarantees secure disconnection in case of
circuit isolation or interruptions in power supply and avoid isolated operation.
The DC arc-fault circuit interrupt (AFCI) is integrated into E6-TL-US and E8-TL-US . It complies
the requirement as Type 1 device in UL1699B standard, series arc faults can be detected.
The inverter can be operated in an ambient temperatures from 22 °F to 149 °F (-30°C to +65°C).
The following diagram illustrates how the output power of the solar inverter is reduced automati-
cally in accordance with ambient temperature.
The device should be installed in a well-ventilated, cool and dry location.
Due to tolerrance of temperature sensor and e󰀩ciency di󰀨erence under di󰀨erent PV voltage, this
derating curve may be a litte di󰀨erent from actual behaviors of unit.
