2. Yotta DPI-208 and DPI-480 System Introduction 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.
3. Yotta DPI-208 and DPI-480 Microinverter Introduction 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 information, 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.
4. Yotta DPI-208 and DPI-480 System Installation A PV system using DPI-208 and DPI-480 Microinverters is simple to install. Each Microinverter easily mounts on the PV racking, directly beneath the PV module(s). Low voltage DC wires connect from the PV module directly to the Microinverter, eliminating the risk of high DC voltage. Installation MUST comply with local regulations and technical rules. - Perform all electrical installations in accordance with local electrical codes.
4.3 PV Rapid Shutdown Equipment (PVRSE) This product is PV Rapid Shut Down Equipment and conforms with NEC-2014 and NEC-2017 section 690.12, for AC and DC conductors, when installed according to the following requirements: 1) Microinverters and all DC connections must be installed inside the array boundary. 2) The array boundary is defined as 305 mm (1 ft.) from the array in all directions, or 1 m (3 ft.) from the point of entry inside a building.
4. Yotta DPI-208 and DPI-480 System Installation 4.4 Installation Procedures 4.4.1 Step 1 - Verify the grid voltage to match with Microinverter rating 4.4.2 Step 2 - Install the AC bus cable A) The AC bus is installed at a position matching the microinverter location. B) One end of the AC bus enters the junction box for connection to the power grid. C) Wire the conductors of the AC bus: L1 - BLACK; L2 - RED; L3 - BLUE.
4. Yotta DPI-208 and DPI-480 System Installation 4.4.4 Step 4 - Ground the system There’s two options to properly ground the microinverter: A) Using the grounding washer. B) Using grounding copper wire through the grounding lug. A B Grounding Lug Grounding washer WARNING! SHARP EDGES 4.4.5 Step 5 - Connect the DPI-208 and DPI-480 microinverter to AC bus cable Connect the DPI-208 and DPI-480 to the AC bus cable. Push the Microinverter AC connector to the Bus cable connector. Listen for the "Click".
4. Yotta DPI-208 and DPI-480 System Installation 4.4.7 Step 7 - Connect DPI-208 and DPI-480 Microinverters to the PV Modules When plugging in the DC cables, the microinverter should immediately blink green ten (10) times. This will happen as soon as the DC cables are plugged in and will show that the microinverter is functioning correctly. This entire check function will start and end within ten (10) seconds of plugging in the unit, so pay attention to these lights when connecting the DC cables.
4. Yotta DPI-208 and DPI-480 System Installation Yotta DPI-208 and DPI-480 Microinverter & Energy Communication Unit Warranty The Yotta DPI-208 and DPI-480 Installation Map is a diagram of the physical location of each DPI-208 and DPI-480 Microinverter in your PV system. Each DPI-208 and DPI-480 Microinverter has a removable serial number label located on the mounting plate. Peel the label and place it according to the respective location on the Yotta DPI-208 and DPI-480 Installation Map.
5. DPI-208 and DPI-480 System Operating Instructions To operate the DPI-208 and DPI-480 microinverter PV system: 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 breaker.
6. Troubleshooting Qualified personnel can use the following troubleshooting steps if the PV system does not operate correctly: 6.1 Status Indications and Error Reporting 6.1.1 Start up LED One quick red light followed by three short green blinks when DC power is first applied to the Microinverter indicates a successful Microinverter startup. 6.1.2 Operation LED Flashing Flashing Flashing Flashing Slow Green (5 sec. gap) - Producing power and communicating with ECU Slow Red (5 sec.
6. Troubleshooting 6.2 Troubleshooting a non-operating DPI-208 and DPI-480 Microinverter 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).
7. Replacing a DPI-208 and DPI-480 Microinverter Follow the procedure to replace a failed Microinverter A) Turn off circuit breaker first. B) Disconnect the Microinverter from the PV Module, in the order shown below: 1) Disconnect the inverter AC connector from the AC Bus. 2) Disconnect the first AC connector in the branch circuit. 3) Disconnect the PV module DC wire connectors from the microinverter. 4) Remove the Microinverter from the PV array racking. C) Install a replacement Microinverter to the rack.
8. Technical Data 1) Be sure to verify the voltage and current specifications of your PV module match with those of the Microinverter. Please refer to the datasheet or user manual. 2) You must match the DC operating voltage range of the PV module with the allowable input voltage range of the Yotta DPI-208 and DPI-480 Microinverter.
