Yotta DPI-208, Инструкция по установке и эксплуатации

Страница: 7 / 26

This integrated system improves safety; maximizes solar energy harvest; increases system reliability, and
simplifies solar system design, installation, maintenance, and management. In a typical string inverter
installation, PV modules are connected in series adding the PV panel voltages which can exceed 1000VDC
at the end of the PV string. This extreme high DC voltage brings a risk of electrical shocks or electrical
arcs which could cause fire.
Yotta DPI connects PV modules are connected in parallel which does not increase the PV panel voltage.
DC voltages in the system never exceeds PV panel Voc, which is typically lower than 60Vdc. This low volt-
age is considered “safe to touch” by fire departments and negates the risk of electrical shock, electrical
arcs and fire hazards
Yotta DPI-208 and DPI-480 maximize PV energy production
2. Yotta DPI-208 and DPI-480 System Introduction
Two PV modules in parallel inside the Yotta DPI-208/480 and share Maximum Peak Power Tracking
(MPPT) controls, which ensures that the maximum power is produced to the utility grid regardless of the
performance of the other PV modules in the array. When PV modules in the array are affected by shade,
dust, orientation, or any situation in which one module underperforms compared with the other units,
the Yotta DPI-208 and DPI-480 Microinverter ensures top performance from the array by maximizing the
performance of each module pair within the array.
More reliable than centralized or string inverters
The distributed Yotta DPI-208 and DPI-480 Microinverter system ensures that no single point of system
failure exists across the PV system. Yotta Microinverters are designed to operate at full power at ambient
outdoor temperatures of up to 149°F (65°C). The inverter case is designed for outdoor installation and
complies with the IP67 environmental enclosure rating.
Simple to install
You can install individual PV modules in any combination of module quantity, orientation, type, and
power class. However, modules connected to the same MPPT channel must have the same electrical
specifications and be the same power class.
Smart system performance monitoring and analysis
The Yotta Energy Communication Unit (ECU) is installed by simply connecting it to AC power and provid-
ing an Ethernet or Wi-Fi connection to a broadband router or modem. After installing and configurating
the ECU, the full network of Microinverters automatically reports to the Yotta Energy Monitor and Analysis
(EMA) web server. The EMA software displays performance trends, informs you of abnormal events, and
controls system shutdown when it is needed. (See ECU manual for instructions.)
