I'm using 6 110 watt panels and 2 Victron charge controllers (3 panels wired in series on each) to charge my 3 48V Dakota Lithium batteries with no issues other than the amount of time required.? I think the bigger issue is where you're located.? I'm on Lake Ontario and I'm getting only around 10 - 15% efficiency even on the sunniest days in the summer due to cloud cover and our northern lattitude.
