2. Yotta DPI-208 and DPI-480 System Introduction
The Yotta DPI-208 and DPI-480 Microinverter is used in utility-interactive grid-tied applications, com-
prised of three key elements:
-Yotta DPI-208 and DPI-480 Microinverter
- Yotta Energy Communication Unit (ECU)
-Yotta Energy Monitor and Analysis (EMA) web-based monitoring and analysis system
5

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 aected 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.)

The Yotta DPI-208 and DPI-480 Microinverter connect to 3 phase grids and operate with most 60 and 72
cell PV modules. Contact Yotta Energy Customer Support for checking compatibility. For more informa-
tion, please see the Technical Data section of this manual.
Yotta's DPI family is expanded with the DPI-208/480 native 3-phase quad microinverters at power ratings
up to 1800VA (for the DPI-480) designed to be used with modern larger power PV modules. With a
balanced 3-phase output, 4 DC inputs, encrypted ZigBee signals, the DPI-208/480 family benefits from
an entirely new architecture.
The components are encapsulated with silicone to reduce stress on the electronics, facilitate thermal
dissipation, enhance waterproof properties, and ensure maximum reliability of the system via rigorous
testing methods including accelerated life testing.
The new DPI-208/480 is interactive with power grids featuring RPC (Reactive Power Control) to better
manage photovoltaic power spikes injected into the grid. In addition, it provides 96.5% peak eciency
with 20% less components compared to the last generation product.

1) Turn ON the AC circuit breaker on each Microinverter AC branch circuit.
2) Turn ON the main utility-grid AC circuit breaker. Your system will start producing power after a locally
mandated delay, usually 5 minutes..
3) The units should start blinking green every 2 seconds five minutes after turning on the AC circuit break-
er. This means they are producing power normally, but have not yet connected to the ECU. After the ECU
has been plugged in, setup acknowledges the Microinverters, they will start to blink green every 10 sec-
onds.
4) Install and setup the ECU according to the instructions in the ECU manual
5) The Yotta DPI-208 and DPI-480 Microinverters will start to send performance data over ZigBee to the
ECU. The time required for all the Microinverters in the system to report to the ECU will vary with the

Qualified personnel can use the following troubleshooting steps if the PV system does not operate
correctly:
6.1 Status Indications and Error Reporting
6. Troubleshooting
6.1.1 Start up LED
One quick red light followed by three short green blinks when DC power is first applied to the Microinvert-
er indicates a successful Microinverter startup.
6.1.2 Operation LED
Flashing Slow Green (5 sec. gap) - Producing power and communicating with ECU
Flashing Slow Red (5 sec. gap) - Not producing power but communicating with ECU
Flashing Fast Green (2 sec. gap) - Not communicating with ECU over 60mins, but still producing power.
Flashing Fast Red (2 sec. gap) - Not communicating with ECU over 60mins and not producing power.
6.1.3 GFDI Error

Microinverter, be sure to watch for the three short LED flashes.
14

6.2 Troubleshooting a non-operating DPI-208 and DPI-480 Microinverter
6. Troubleshooting
There are two possible overall areas of trouble:
A) The Microinverter itself may be having problems.
B) The Microinverter itself is working fine but it is having trouble communicating with the ECU. The items
below refer to Microinverter issues, not communication issues (addressed in the ECU manual).
A quick way to tell whether the issue is wih the Microinverter or a communication problem with the ECU:
1) Diagnosing the Microinverter: A red light – either blinking or solid on the Microinverter, or no light at all.
No light, or a red light, means it is definitely a Microinverter problem.
2) Diagnosing from the ECU:
A) No-Data-Display: This is probably a communication issue, not a Microinverter problem.
B) Problems with erratic display: Data is displayed for some period and then no data is displayed. Most
likely a communication issue.
C) 0 watts, or 2 watts: Possibly a Microinverter problem.
D) Erratic data display that is not coordinating with data displays from other units is most likely a Microin-
verter problem.
To troubleshoot a non-operating DPI-208 and DPI-480 Microinverter,
Follow the steps below in order:
No need for maintenance.
Do not attempt to repair the DPI-208 and DPI-480 Microinverter. If troubleshooting
methods fail, please return the microinverter to your distributor for replacement.
6.3 Maintenance
1) Verify the utility voltage and frequency are within ranges shown in the Technical Data section of this
manual.
2) Check the connection to the utility grid. Verify utility power is present at the inverter in question by
removing AC, then DC power. Never disconnect the DC wires while the microinverter is producing power.
Re-connect the DC module connectors and watch for three short LED flashes.
3) Check the AC branch circuit interconnection between all the microinverters. Verify each inverter is
energized by the utility grid as described in the previous step.
4) Make sure that any AC breaker are functioning properly and are closed.
5) Check the DC connections between the microinverter and the PV module.
6) Verify the PV module DC voltage is within the allowable range shown in the Technical Data of this
manual.
7) If the problem persists, please call Yotta Energy Customer Support.
