2 Introduction

With this device you have acquired a solar inverter for connection of photovoltaic systems to the
grid. This solar inverter is characterized by an advanced housing design and state-of-the-art high-

frequency technology, which enable the highest levels of e󰀩ciency.

The solar inverter includes series monitoring units, such as anti-islanding protection, display,
RS485 (EIA485) interfaces.

The inverter is usable indoor and outdoor. It fullls the directives of ANSI/NFPA 70, NEC 690.5, UL

1741, UL 1741 SA,IEEE 1547 and IEEE 1547.1 for parallel operation of power generation plants
on low-voltage network of regional electrical utility companies.
.
The function of the anti-islanding protection (automatic isolation point for in-plant generation sys-

tems) stipulates compliance with the specications of UL 1741,UL 1741 SA and IEEE 1547.

In the following 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 handling of the solar
inverter.

The inverter not only meets the safety requirements of UL 1741, but also complies with the

specications of UL 1741 SA for Grid Support Utility Interactive Inverters that support a more
stable utility grid. Delta SOLIVIA TL series were testing to the UL 1741 SA for CA Rule 21 and
other Source Requirement Document (SRD) including ‘PG&E Electric Rule No.21 Hh’ Jul,2017, ‘SCE
Rule21 Hh’, ‘SDGE Rule21 Hh’ and ‘HECO SRD-UL-1741-SA-V1.1’.
In the following 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 handling of the solar
inverter.

2.1 System

The content of renewable energy with respect to overall power consumption worldwide is increas­ing annually by approximately 25%. The reason for this rise can be primarily attributed to the con­stantly increasing demand for power, the increasing interest in environmentally friendly technolo­gies, 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 en­sured 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.

2.2 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 capa­ble 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.

The read-out of the data over the integrated interface (RS485,BLE4.0,Zigbee,WIFI) is possible only
in solar operation.

2.3 Technical structure of the solar inverter

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. Mea­sures must be taken to ensure that the maximum no- load voltage of 600 V 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 NEMA 4 (NEMA 3R for wiring

box) and is protected by an anti-corrosion nish. The heat sink on the M series inverters

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 solar inverter is controlled by microcontrollers which provide interface communication and the
values and messages on the front-panel display.

AC grid monitoring is done by an independent dedicated micro controller set up to meet the require­ments 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 and accessible
interfaces (display, RS485 interface ). Relevant standards concerning electromagnetic compatibility

(EMC) and safety are fullled.

The solar inverter is functional in grid-parallel operation exclusively. An automatically anti-islanding

function, 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 M4-TL-US,M5-TL-US,M6-TL-US, M8­TL-US ,and M10-TL-US . It complies the requirement as Type 1 device in UL1699B standard,
series arc faults can be detected.

The solar inverter can be operated in an ambient temperatures from 22 °F to 149 °F (-30°C to
+60°C). The following diagram illustrates how the output power of the solar inverter is reduced
automatically 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

(3) LED Lights - The three LED lights indicate errors or status as described in section 8.

(4) Mounting Plate - The inverter ships with a mounting plate that allows easily assembly of the
inverter to a wall.

(5) Wiring Box - This is the compartment where all the wiring for the inverter inputs and outputs
plus the RS485 communication are done.

(6) Conduit Plugs - There are 6 - 3/4“ conduit openings and 2 - 1/2“ conduit openings. Each

conduit opening comes tted with a conduit plug that should be removed before installing conduit
ttings. Conduit ttings need to be water tight with either NEMA 4, 4X, 6, or 6X rated, and insula-

ted type is preferred.

DC Disconnect shown with lock in o󰀨 position. There are one openings on the disconnect where a

padlock can be attached as shown above.
