📝 Description
New product. The SolarMax Potentialausgleichsset (Article 2020-1) is an original SolarMax kit for equipotential bonding and grounding of the photovoltaic generator, intended for use with specific SolarMax inverters and systems. SolarMax documentation identifies the Potentialausgleichsset (PAS) as an accessory used for grounding the PV generator and also provides for monitoring of a possible PAS fuse interruption by the inverter.

The AD202JN used on the board is a galvanic isolation amplifier from Analog Devices, designed to transfer signals without a direct galvanic connection between input and output; the component is now classified as obsolete by the manufacturer/distributors.
⚡ Function in the Electrical System
ON-GRID photovoltaic system – PV generator and SolarMax inverter.
The Potentialausgleichsset (PAS) is used to establish the ground connection of the photovoltaic generator as part of the inverter's protection and control system. SolarMax documentation expressly specifies that the PAS is an accessory intended for grounding the PV generator.
The electronic circuit contained in the kit also allows the associated control-system signals to be electrically interfaced and isolated. The AD202JN is an isolation amplifier intended for signal measurement and isolation applications, including high-voltage instrumentation.
🏭 Construction and Installation
The kit consists of a pre-assembled SolarMax electronic board, mounted in a green support, with terminal blocks, wiring, fuse and protection/interface components. The photographs also show the pre-installed wiring and connection accessories included in the package.
The kit must be installed and connected exclusively according to the diagram specified for the compatible SolarMax inverter model. It should not be considered a universal grounding device for every photovoltaic system.
🛡️ Safety and Product Condition
New old-stock product, stored in the original SolarMax packaging. The contents appear complete and in good condition, with wiring and components present in the package. The box shows normal storage marks due to age.
The component is intended for electrical systems where dangerous DC voltages may be present. Installation, testing and connection must be carried out by qualified personnel. SolarMax documentation specifies that installation work on the relevant inverters must be performed by qualified electrical personnel.
