Frequently Asked Questions

interVOLT products are currently sold through various wholesale and retail distributors. If you would like to be put in touch with your closest and most relevant distributor please use the “contact us form” to let us know where you are located and whether this is a trade or retail enquiry, we can point you in the right direction.

We have published a brochure highlighting the differences between parallel type charging (the EBI) and DC to DC charging (the DCC). This can be downloaded here and should allow you to work out what device will best suit your application.

The fuse is there to protect the cable from carrying excessive current, for example, in the instance of a positive cable shorting out on the vehicle chassis. The fuse needs to be rated high enough to carry the continuous and peak loads however within the cable rating to allow it to trip should the load exceed the cables specification. It is important to note that the EBI Pro has its own over current protection and that the fuse is only required to protect the cable.

Refer to the manual (page 16). The internal components of the device are sealed to IP67. The device is also rated for continuous operation at 60̊ C.

Refer to the manual (page 17). The cable needs to be capable of carrying the continuous and peak current of the application, in dual battery systems utilising parallel charging (such as the EBI Pro) the transfer of current between two batteries can be hundreds of amps for short periods of time. Cable will also need to be appropriately sized to overcome voltage drop (this will be subject to the length of the cable run). If you are unsure on how to correctly size up your cable please contact a suitably qualified DC Electrician for advice.

We strongly recommend that any work being undertaken to install our (or any) DC electrical power products are done so by a suitably qualified person such as a DC Auto Electrician. Whilst the team at interVOLT have strong technical knowledge on our products we are not qualified electricians and cannot give general installation advice. If the advice you are seeking is outside the scope of our device or application you will need to speak with your supplier or a DC electrician.

This isn’t a problem, this indicator lets the vehicle operator know that the EBI Pro is still engaged and therefore the start and auxiliary batteries are in parallel. In this instance the voltage of the start battery is still above the isolate voltage and therefore the EBI has not isolated the batteries. Once the voltage does drop below the isolate voltage the device will switch off/isolate.

The EBI is designed to be connected between two batteries, if the auxiliary battery is disconnected from the EBI Pro for any reason device will respond in one of two ways. 1. The in vehicle indicator will flash indicating the voltage on the auxiliary side of the EBI Pro is below the low voltage alarm point (as the voltage will be 0). Or the EBI will show B1 on the display indicating that only battery one is being sensed and therefore the EBI will not operate until the second battery is connected. In both cases this is not an issue for the EBI Pro itself and the device will return to normal operation once the second battery is connected to the circuit once again.

In general terms, the EBI Pro is designed for 12VDC dual battery installations in passenger, RV and 4WD vehicles. If this is your application then the EBI Pro would be our first recommendation.
