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 congured via APP.
A very powerful tool for monitoring, conguration 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 dierent 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 eciency for either 240 Vac or 208 Vac
AC grids.
