I have had a 5Kva Mecer Axpert MKSII inverter/charger installed with 4 x 200ah gel batteries in my home for load shedding.
I have a small 2 bed simplex and it was hard to find a place to put the unit so it wasnt in the lounge or bedrooms.So its in the passage.
Unfortunately this particular inverter runs the fans 24/7 which is rather annoying.Its not loud as such but still noticeable.
Im thinking of switching the inverter off when there is no load shedding.On research i see batteries discharge at approx 4% per week when not being coupled to the inverter.
I could switch the inverter on every 3rd or 4th day while im working so that the fans dont annoy me and the family.

What are the disadvantages to the inverter/batteries/whole system if i did this?
