Sungrow 1-Phase Hybrid Inverter

Introduction and General Information

This guide provides essential information for the quick installation of the Sungrow 1-Phase Hybrid Inverter. The content may be updated periodically. This guide is not a substitute for the user manual or other related notes on the device.

All operations must be performed by qualified personnel trained in electrical system installation, commissioning, hazard management, and familiar with the manual and local regulations.

Before installation, verify that all package contents are intact and complete. Contact Sungrow or the distributor for any damaged or missing components. Ensure cables are intact and well-insulated, and personnel wear appropriate Personal Protective Equipment (PPE).

Violation of these instructions could result in personal death, injury, or device damage, and will void the warranty.

Safety

The inverter is designed and tested according to international safety regulations. Read and observe all safety instructions carefully before and during any work on or with the inverter. Incorrect operation can cause:

• Injury or death to the operator or a third party.
• Damage to the inverter or other properties.

Follow safety instructions related to PV strings and the utility grid.

⚠️ DANGER: Lethal Voltage!

• PV strings produce electrical power when exposed to sunlight, posing a lethal voltage and electric shock hazard.
• Only qualified personnel can perform the wiring of PV panels.

⚠️ NOTICE: Danger from Electric Shock!

• All electrical connections must comply with local and national standards.
• Connection to the utility grid requires permission from the local utility grid company.

Inverter Safety Labels

The inverter body has warning labels:

• ⚠️ Disconnect from power: Disconnect the inverter from all external power sources before maintenance.
• ⏱️ 10 min Wait: Do not touch live parts for 10 minutes after disconnection from power sources.
• ? Hot Surface: Burn danger due to hot surfaces that may exceed 60 °C.
• ⚡ High Voltage: Danger to life due to high voltages. Only qualified personnel can open and maintain the inverter.
• ℹ️ Read Manual: Read the user manual before maintenance.

DANGER: Live Voltage and Shock Hazard

• Do not open the enclosure while the inverter is operating. Unauthorized opening voids warranty and may terminate the operating license.
• Removing the enclosure lid exposes live components, posing a risk of death or serious injury from electric shock.
• Only operate the inverter if it is technically faultless and in a safe state. Operating a damaged inverter can lead to hazardous situations.

WARNING: Risk of Inverter Damage or Personal Injury

• Do not pull out PV connectors, AC connector, or battery connectors while the inverter is running. De-energize the unit from all power sources, wait 10 minutes for internal capacitors to discharge, and verify no voltage or current before disconnecting any connector.
• All warning labels and the nameplate on the inverter body must be clearly visible, and not removed, covered, or pasted over.

CAUTION: Risk of Burns from Hot Components!

• Do not touch hot parts (e.g., heat sinks) during operation. Only the LCD display and the DC switch can be safely touched at any time.

NOTICE: Country Setting and ESD Hazard

• Country setting must be performed only by qualified personnel. Unauthorized alteration may cause a breach of type-certificate marking.
• Risk of inverter damage due to Electrostatic Discharge (ESD): Avoid unnecessary touching and wear a grounding wristband before touching connectors.

Battery Safety

DANGER: Battery Hazards

• Batteries deliver electrical power, posing burn or fire hazards when short-circuited or wrongly installed.
• Lethal voltages are present at battery terminals and cables within the inverter. Contact can cause severe or fatal injuries.

NOTICE: Battery Damage

• Improper settings or maintenance can permanently damage the battery.
• Incorrect inverter parameters lead to premature battery aging.

Wiring Diagrams

The document includes wiring diagrams for different systems and regions. These diagrams illustrate the connection of the inverter with batteries, PV panels, grid, loads, and various protection devices.

Scope of Delivery and Installation Tools

The document lists the items included in the scope of delivery, such as the inverter, wall-mounting bracket, expansion plug set, screw sets, connector sets, and documents. It also details the necessary installation tools, including a marker, multimeter, hammer drill, wire stripper, hydraulic plier, crimping tools, screwdrivers, heat gun, RJ45 crimping tool, wrenches, and Allen wrench.

Mounting Location Considerations:

• Temperature ranges: 60 °C (+140 °F) maximum, -25 °C (-13 °F) minimum.
• Humidity: 0-100% (non-condensing).
• Clearances: Minimum distances are specified for ventilation and access (e.g., ≥400mm, ≥500mm, ≥300mm).
• Mounting orientation and position are illustrated with acceptable and unacceptable examples.

Installation Steps

Detailed steps are provided for mounting the inverter, including drilling holes, securing brackets, and tightening screws with specified torque values.

Mounting:

• Step 1: Measure and mark mounting points on the wall (e.g., 415mm horizontal, 380mm vertical, 40mm from top).
• Step 2: Drill holes of specified depth (approx. 70 mm) and diameter (φ10).
• Step 3: Insert expansion plugs.
• Step 4: Mount the bracket using M6 screws (9.0 N.m torque).
• Step 5: Secure the inverter using two screw sets (left and right sides), with M4 screws (1.2 N.m torque).

PE / Grounding:

• Step 1: Prepare the grounding cable (L = E + (2~3)mm).
• Step 2: Apply heat shrink tubing.
• Step 3: Crimp the terminal.
• Step 4: Connect the PE wire to the grounding terminal.
• Step 5: Secure the PE connection with an M5 screw (2.0 N.m torque).

Cable specifications must comply with local regulations or be consistent with the PE wire in the AC cable.

AC Connection:

• Step 1-2: Prepare AC connectors (e.g., 12-16mm, 16-21mm, 21-25.8mm cable lengths).
• Step 3: Prepare AC cables (PE, N, L) for connection (e.g., 6-16 mm² recommended 10 mm²).
• Step 4-7: Connect the AC cables (PE, N, L) to the inverter's AC connector, ensuring correct polarity and secure connections.
• Step 8-11: Connect the AC connector to the inverter, ensuring a secure click and tightening the locking nut (e.g., 5.0-6.0 N.m torque).
