Installed a MultiPlus 1600 12/70 onto a sailing vessel, but it does not charge the 630AH 12v Exide Gel Battery Bank with more than max 13,3 volt. So, when shore power or the vessels AC generator is putting in 230v AC to the multiplus and the unit/charger makes a lot of annoying noise, the battery bank actually continues to discharge. The unit is brand new with all settings set as default.
The point of installing a new Victron Multiplus was to utilize the 70 AMPs charger to charge the battery bank faster especially from the boats 230v AC generator, when the other suppliers of current from the ship (wind turbine, hydro generator and solar) wouldn't be able to cope with consumption. So, the charger-unit has to go into full charge voltage of 14,4v (no more) with 70 AMPs charging current instantly when the MultiPlus is powered from an AC source. even when the battery bank is already charged 90%. The battery bank always must be fully charged before passages or before nights at anker etc. as we don 't want to run the generator when sailing or when sleeping.
Is the Multiplus 1600/12/70 capable of delivering what ordinary stand alone charges can? Or will I have to return the unit to the seller as a faulty product (a battery charger has to be able to charge instantly also on a nearly fully charged battery bank) and reinstall my old Clayton 1213 Sinus Inverter together with a new 70 AMPs ordinary battery Charger?
