Victron Energy Isolation Transformer - 2000W - 115/230 VAC [ITR040202041]

Safety and prevention of galvanic corrosion The Isolation Transformer eliminates any electrical continuity between AC shore power and the boat. It is essential for safety and eliminates the need for galvanic isolators and polarity alarms. 

Safety is taken for granted in case of a normal on-shore installation. A fuse will blow or a GFCI (Ground Fault Current Interrupter) will trip in case of a short circuit or current leakage to ground. Connecting the ground wire of the shore-side supply to the metal parts of the boat will result in galvanic corrosion (see below). Bringing only the live and neutral wire on board results in an unsafe situation because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat. 

Galvanic corrosion occurs when two dissimilar metals in electrical contact are simultaneously exposed to an electrically conducting fluid. Seawater and, to a lesser extent, fresh water are such fluids. In general, the more active alloy of the couple corrodes preferentially while the less active (more noble) material is cathodically protected. The rate of galvanic corrosion is a function of several variables including area ratios, conductivity of the fluid, temperature, nature of the materials, etc. 

It is a misunderstanding that galvanic corrosion occurs only in metal and aluminium hulls. In fact it can occur on any boat as soon as a metallic part (the shaft and propeller) is in contact with water. Galvanic corrosion will quickly dissolve your sacrificial anodes, and attack the shaft, propeller and other metal parts in contact with water as soon as the boat is connected to the shore-side supply. It might therefore be tempting not to connect the ground conductor: this is however extremely dangerous because GFCIs will not work nor will a fuse blow in case of a short circuit to a metal part on the boat. 

The best solution to avoid galvanic corrosion and at the same time prevent any unsafe situation is to install an Isolation Transformer to connect to the shore-side supply. 

The Isolation Transformer eliminates any electrical continuity between shore power and the boat. The shore power is fed to the primary side of the transformer and the ship is connected to the secondary. The Isolation Transformer completely isolates the boat from the shore ground. By connecting all metal parts to the neutral output on the secondary side of the transformer, a GFCI will trip or a fuse will blow in case of a short circuit. 

Soft startis a standard feature of a Victron Energy isolation transformer. It will prevent the shore power fuse from blowing due to the inrush current of the transformer, which would otherwise occur

Product Warranty

Victron Energy Product Warranty

Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end-user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead-acid batteries; 2 years from date of purchase by the end-user, with a maximum of 30 months from the Victron Energy invoice date, Lithium batteries; 3 years from date of purchase by the end-user. In addition to this, proof of correct battery usage is required when making a battery warranty claim.

For a 10% surcharge on the net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before expiration of the original term.

During the warranty period, Victron Energy will, at its discretion, repair, replace or credit the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation, and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like:

• Reverse of battery polarity.

• Inadequate connection.

• Mechanical shock or deformation.

• Contact with liquid or oxidation by condensation.

• Use in an inappropriate environment(dust, corrosive vapor, humidity, high temperature, biological infestation...). 

• Breakage or damage due to lightning.

• Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening.

• For any electronic breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state of the internal control diode and/or the input/output X and Y capacitors determine the warranty.

This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Victron Energy or one of its authorized Repair Centres. In order to qualify for the warranty, the product must not be disassembled or modified.

Repair, replacement or credit are our sole remedies and Victron Energy shall not be liable for damages, whether direct, incidental, special, or consequential, even caused by negligence or fault.

Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers when performing warranty repairs or building replacement products. If Victron Energy repairs or replaces a part of a product, its warranty term is not extended.

All remedies and the measure for damages are limited to the above.

Victron Energy shall in no event be liable for consequential, incidental, contingent or special damages, even if having been advised of the probability of such damages. Any and all other warranties expressed or implied arising by law, course of dealing, course of performance, usage of trade or otherwise, including but not limited to implied warranties of merchantability and fitness for a particular purpose, are limited in duration to a period of five (5) years from the date of purchase, with the exception of batteries. For lead acid batteries a two (2) year period applies and for lithium batteries a three (3) year period applies.
