Converting Voltages; Soft Start; Internal Wiring Diagram - Victron energy 2000W Manual

The shore ground is isolated from the vessel ground, and galvanic
corrosion originating from the shore connection is blocked.

2.3. Converting voltages

The isolation transformer converts the input voltage with a 1:1.05 ratio. The 1:1.05 transformer ratio boosts the output voltage of
the isolation transformer by 5%. This is to compensate for shore power voltage drops that are a common occurrence in marinas.
The isolation transformer can be used in 115V or 230V systems and also be used to convert 230V to 120V and 115V to 240V.
Depending on the isolation transformer configuration:
• A 230V input becomes 240V.
• A 230V input becomes 120V.
• A 115V input becomes 240V.
• A 115V input becomes 120V.
The isolation transformer can be used in 50Hz or 60Hz systems. However, the isolation transformer cannot convert frequencies
from 50Hz to 60Hz or vice versa.

2.4. Soft start

Soft start is a standard feature of a Victron Energy isolation transformer. It will prevent the shore power circuit breaker from
tripping due to the transformer inrush current.
