I posted here because the reply from the email address Victron give for technical enquiries and sales was a waste of time .

" *Many thanks for your request and interesse in our products!*

*For quotes on pricing, system support, repairs and technical questions in general we would like to advise you to contact your local distributer or authorized dealer.* "

I have had experience of the local dealer and i know that they will tell you whatever they need to in order to sell something .

The reason for needing the information is because i needed to know if they advertise their products output by either the arithmetical amperes or the efficient amperes method , reading below you will appreciate there is a big difference . I have Ferve 16 amp charger and a second 20 amp one a the moment and its output of the Ferve is around 23 amps and the other around 29 amps as both companies advertise their products using the legal EU method .

*The value of the charge current must be expressed in arithmetical amperes. This is the only*

*value officially accepted under the EN 60335-2-29 European regulations.*

*Nevertheless, many battery charger manufacturers express the charge current of their*

*products in efficient amperes, thus not complying with these European regulations. The*

*reason is that 1 arithmetic ampere is equal to 1.4142 effective amperes. So a battery charger*

*of 8 effective amperes must actually be considered as one of 5.66 amperes. Therefore, to*

*avoid deception, it is necessary to know whether the battery charger manufacturer uses*

*arithmetic or effective amperes when stating the charge current.*"
