2 SAFETY

2.1 Intended Use

The product is a transformerless hybrid inverter with 2 or 3 MPP trackers and a battery connection. It feeds DC current from the PV array into the connected battery or converts it to grid-compliant three-phase current for the utility grid. It can also convert DC current from the battery into grid-compliant three-phase current. The product features a backup function to supply selected circuits with power from the battery or PV system during a grid fault. It is intended for indoor and outdoor applications.

Connection must be made only with PV modules of protection class II (in accordance with IEC 61730, application class A). Do not connect any other energy sources. The product lacks integrated transformer and galvanic isolation. It must not be operated with PV modules requiring functional grounding of positive or negative PV conductors, as this can cause irreparable damage. PV modules with frames requiring protective earthing are permissible. All components must operate within their permitted ranges and installation requirements.

Use the product only as per the user manual and applicable local standards/directives. Other applications may cause personal injury or property damage.

The product must be operated with an intrinsically safe lithium-ion battery approved by AISWEI, with its voltage range fully within the product's permissible input voltage range. Use is restricted to countries approved by AISWEI and the grid operator. The type label must remain attached and legible. This document does not replace regional, state, provincial, federal, or national laws, regulations, or standards for installation, electrical safety, and product use.

2.2 Important Safety Instructions

The product is designed and tested according to international safety requirements. Residual risks exist despite careful construction. To prevent injury and damage, and ensure long-term operation, read this section carefully and observe all safety information.

DANGER: Danger to life due to high voltages of the PV array or the battery!

DC cables connected to the battery or PV array may be live. Touching DC conductors or live components can cause lethal electric shocks. Disconnecting DC connectors under load may cause electric arcs, leading to shock and burns.

• Do not touch non-insulated cable ends.
• Do not touch the DC conductors.
• Do not touch any live components of the product.
• Do not open the product.
• Observe all safety information from the battery manufacturer.
• All work must be carried out by qualified personnel who have read and understood this document and the user manual.
• Disconnect the product from all voltage and energy sources and ensure it cannot be reconnected before working.
• Wear suitable personal protective equipment (PPE).

DANGER: Danger to life due to electric shock when touching live components in backup mode!

Even with AC breaker and PV switch disconnected, system parts may remain live when the battery is in backup mode. Do not open the product. Disconnect from all voltage and energy sources and ensure it cannot be reconnected before working.

DANGER: Danger to life due to fire or explosion when batteries are fully discharged!

Incorrect charging of fully discharged batteries can cause fire, leading to death or serious injury. Ensure the battery is not fully discharged before commissioning. Contact the battery manufacturer for proceedings if the battery is fully discharged.

DANGER: Danger to life due to burns caused by electric arcs through short-circuit currents!

Short-circuit currents in the battery can cause heat accumulation and electric arcs if the battery is short-circuited or wrongly installed, potentially leading to lethal injuries from burns. Disconnect the battery from all voltage sources before working on it. Use only properly insulated tools. Observe battery manufacturer's safety information.

DANGER: Danger to life due to electric shock when touching live system components in case of a ground fault!

If a ground fault occurs, system parts may remain live. Touching live parts and cables can result in death or lethal injuries. Disconnect the product from voltage and energy sources and ensure it cannot be reconnected before working. Only touch PV module cables on their insulation. Do not touch substructure or frame parts of the PV array. Do not connect PV strings with ground faults.

WARNING: Danger to life due to electric shock from destruction of the measuring device due to overvoltage!

Overvoltage can damage a measuring device, causing voltage to be present in its enclosure. Touching a live enclosure can result in death or lethal injuries. Use measuring devices with a span higher than the DC input voltage range or equal to the product's voltage rating.

CAUTION: Risk of burns due to high temperature.

Some enclosure parts can become hot during operation. Do not touch parts other than the enclosure lid during operation.

CAUTION: Risk of injury due to weight of product.

Injuries may result if the product is lifted incorrectly or dropped during transport or mounting. Transport and lift the product carefully, considering its weight. Wear suitable PPE.
