Once the battery bank has been recharged to 90% state of charge the generator is automatically shut down. The vessel’s battery bank can also be charged from a shore supply. An Isolation Transformer ensures the safety of crew and vessel from ground faults and galvanic corrosion; it also automatically switches between 115 and 230 VAC depending on local supply. The Quattros can easily be programmed with a current limit to match the pontoon’s marine power distribution network threshold. Any power-demand above that threshold will not trip a shore-side fuse thanks to Quattros PowerAssist feature which will instantly supplement excess demand with power from the battery bank. When the power demand falls below the set threshold, the Quattro will make maximum use of shore power by sending any surplus power - up to the threshold - to recharge the batteries.
