Note: * If the battery is integrated with a readily accessible internal DC breaker, no additional DC breaker is required.
Note: **Type B is recommended, and Type C is Compatible. Select an MCB with an appropriate rated current based on the actual requirements, including the overall wiring scheme, the number of loads, and the inverter's load-carrying capacity.
Note: The values in the table are recommended values and can be set to other values according to actual conditions.

Note: *The manual changeover switch should be prepared by users separately. For the whole home backup scenario, it is recommended to use at least a 63A manual changeover switch, with 80A or 100A preferred. When switching to "LOAD" using the changeover switch, household loads will be supplied by the PV installation and battery. When the inverter is faulty or undergoing maintenance, switch to "GRID" to ensure the loads can work normally.

Meter Communication Abnormal Alarm

Step 1: Check whether the communication cables between the inverter and the meter are correctly connected.

Grounding Cable Fault

Step 1: Check whether the PE wire at the LOAD terminal is connected properly in compliance with the standard wiring diagram.

Step 2: Check whether the PE wire at the GRID terminal is connected properly in compliance with the standard wiring diagram.

Step 3: Check whether the external grounding cable of the inverter is connected properly in compliance with the standard wiring diagram.

Safety

The inverter has been designed and tested strictly according to international safety regulations. Read all safety instructions carefully prior to any work and observe them at all times when working on or with the inverter. Incorrect operation or work may cause:

• injury or death to the operator or a third party;
  ■ damage to the inverter or other properties.

Please follow the safety instructions related to the PV strings and the utility grid.

DANGER

Lethal voltage!

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

NOTICE

Danger to life from electric shock due to lethal voltage!

• All electrical connections must be in accordance with local and national standards.
• Only with the permission of the local utility grid company, the inverter can be connected to the utility grid.

Inverter

The warning label on the inverter body are as follows.

Disconnect the inverter from all the external power sources before maintenance!

Danger to life due to high voltages! Do not touch live parts for 10 minutes after disconnection from the power sources.

Burn danger due to hot surface that 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!
	Do not dispose of the inverter together with household waste.
	TÜV mark of conformity.
	CE mark of conformity.EU/EEA Importer.
	RCM mark of conformity.
	Additional grounding point.
	RoHS labelingThe product complies with the requirements of the applicable EU directives.

Users may also attach other warning signs as per the requirements of the local standards or installation specifications.

DANGER

Danger to life from electric shocks due to live voltage

• Do not open the enclosure at any time. Unauthorized opening will void warranty and warranty claims and in most cases terminate the operating license.
• When the enclosure lid is removed, live components can be touched which can result in death or serious injury due to electric shock.

Lethal danger from electric shock due to possibly damaged inverter

• Only operate the inverter when it is technically faultless and in a safe state.
• Operating a damaged inverter can lead to hazardous situations that can result in death or serious injuries due to electric shock.

WARNING

Risk of inverter damage or personal injury

- Do not pull out the PV connectors and AC connector when the inverter is running. Disconnect the AC circuit breaker and set the DC load-break switch of the inverter to OFF. Wait 10 minutes for the internal capacitors to discharge. Verify that there is no voltage or current before pulling any connector.

WARNING

All the warning labels and nameplate on the inverter body:

• must be clearly visible; and
• must not be removed, covered or pasted.

CAUTION

Risk of burns due to hot components!

- Do not touch any hot parts (such as the heat sink) during operation. Only the DC switch can safely be touched at any time.

NOTICE

Only qualified personnel can perform the country setting. Unauthorized alteration may cause:

• A breach of the type-certificate marking.

Risk of inverter damage due to electrostatic discharge (ESD)!

By touching the electronic components, you may damage the inverter. For inverter handling, be sure to:

• avoid any unnecessary touching; and
- wear a grounding wristband before touching any connectors.

Battery

DANGER

Batteries deliver electrical power, resulting in burns or a fire hazard when they are short circuited, or wrongly installed.

Lethal voltages are present in the battery terminals and cables in the inverter. Severe injuries or death may occur if the cables and terminals in the inverter are touched.

NOTICE

Improper settings or maintenance can permanently damage the battery.

Incorrect inverter parameters will lead to the premature aging of battery.
