These days AC gensets are being used to charge larger house banks on vessels. Genset manufacturers claim you cannot have more that 20% of the load coming from non linear sources like chargers. For example the vessels we work on usually have 9kw Gensets. 20% is 1800 watts. When we charge a 30kw 48v house bank at 1800 watts this becomes an issue. Clear solution is to put a DC genset in. I am looking for any solutions to clean up the harmonic distortion created by chargers and does VE do anything special in their charger to reduce this issue?
