D5-Evo, D10 and D10 Turbo User Guide - Centurion Systems

Instead of the 220V charger, you can have a low voltage charger mounted inside the D5-Evo DOMESTIC with a plug-in transformer plugged into the nearest plug point inside the house / building. This saves having to run an electrically compliant 220V supply to the D5-Evo DOMESTIC. Finally you can use a solar panel to charge the battery.
