Col_T Posted August 29, 2019 Report Share Posted August 29, 2019 At present we have a shore-line connection to a Sterling Pro Combi quasi sine wave inverter (1500w) / charger (40A) connected to 5 off 110Ah sealed lead acid batteries. We also have 350w of solar charging the batteries. We usually cruise for about 4 hours a day, and use about 50Ah a day (12v fridge, all LED lighting and charge mobiles, etc via USB). I am planning on replacing the Combi with separate inverter and charger to avoid having all my eggs in one basket, so as to speak. Given that most of the time the charger will be trickle charging the batteries, is there any benefit in having a charger capable of delivering more 30A?

I cannot envisage arriving at a mooring with shore power having flat batteries needing a really hefty charger and if I somehow did I have a 175 amp alternator to do the business til my 30 amp charger is enough. In fact, when my combi failed, a 5a ctek coped quite adequately with my 440 amp hour bank until my new configuration was complete. Link to comment Share on other sites More sharing options...

I see no benefit either, if you had a bigger charger it would not be charging at more than 30A for long, so that is the only time you could reduce with a bigger charger.

Alan de Enfield Posted August 29, 2019 Report Share Posted August 29, 2019 (edited) We have a 1300Ah battery bank and our Victron 50a battery charger is quite happy & does a good job. Edited August 29, 2019 by Alan de Enfield Link to comment Share on other sites More sharing options...
