Models: SH3.0RS / SH3.6RS / SH4.0RS / SH5.0RS / SH6.0RS
This guide provides essential information for the quick installation of Sungrow 1-Phase Hybrid Inverters. Please read and understand the user manual and related regulations before installation.
Important Notes:
- Content may be updated periodically. Information is subject to change without notice.
- This guide is not a substitute for the user manual.
- Installation and commissioning must be performed by qualified personnel trained in electrical systems and aware of local regulations.
- Verify package contents are intact before installation. Contact Sungrow or distributor for any damaged or missing components.
- Use intact and well-insulated cables. Operating personnel must wear appropriate Personal Protective Equipment (PPE).
- Violations may result in severe injury, death, or device damage, and will void the warranty.
Safety Precautions
The inverter is designed and tested according to international safety regulations. Always read and observe all safety instructions when working on or with the inverter. Incorrect operation can lead to:
- Injury or death to the operator or third parties.
- Damage to the inverter or other property.
Follow safety instructions for PV strings and the utility grid.
DANGER: Lethal Voltage!
- PV strings produce electrical power when exposed to sunlight, posing a lethal voltage and shock hazard.
- Only qualified personnel can perform PV panel wiring.
NOTICE: Danger to life from electric shock due to lethal voltage!
- All electrical connections must comply with local and national standards.
- Connection to the utility grid requires permission from the local utility company.
Inverter Safety Labels:
Disconnect the inverter from all external power sources before maintenance.
Do not touch live parts for 10 minutes after disconnection from power sources.
Burn danger due to hot surfaces (may exceed 60°C).
Danger to life due to high voltages!
- Only qualified personnel can open and maintain the inverter.
- Read the user manual before maintenance.
DANGER: Danger to life from electric shocks due to live voltage
- Do not open the enclosure at any time. Unauthorized opening voids warranty and operating license.
- Removing the enclosure lid exposes live components, which can cause death or serious injury.
- Operate the inverter only when it is technically faultless and safe. Operating a damaged inverter can lead to hazardous situations.
WARNING: Risk of inverter damage or personal injury
- Do not pull out PV connectors and AC connectors while the inverter is running. Disconnect the AC circuit breaker and set the DC load-break switch to OFF. Wait 10 minutes for internal capacitors to discharge. Verify no voltage or current before pulling any connector.
WARNING: Warning labels and nameplate
- Must be clearly visible.
- Must not be removed, covered, or pasted over.
CAUTION: Risk of burns due to hot components!
- Do not touch hot parts (e.g., heat sink) during operation. Only the DC switch can be safely touched at any time.
NOTICE: Country setting
- Only qualified personnel can perform country settings. Unauthorized alteration may breach type-certificate marking.
Risk of inverter damage due to electrostatic discharge (ESD)!
- Avoid unnecessary touching of electronic components.
- Wear a grounding wristband before touching any connectors.
Battery Safety:
DANGER:
- Batteries deliver electrical power, causing burns or fire hazard if short-circuited or wrongly installed.
- Lethal voltages are present in battery terminals and cables, posing severe injury or death risk.
NOTICE:
- Improper settings or maintenance can permanently damage the battery.
- Incorrect inverter parameters lead to premature battery aging.
