I am getting ready to purchase an inverter and I am trying to decide which size would be the best choice. I have added up all of our current usage (120v) and come up to around 2200 watts of use. So given startup demands from motors, I would guess that a 3.6 would be very good, for now. But knowing how things go, we will probably be adding more electrical stuff in the future and it seems that I should buy even a higher output inverter so as to have extra available for the future. So, my question is there any downside (other than the purchase price) to having a inverter larger than your usage needs? I realize that if you go from the 24v to 48v system you will need more batteries, but I wonder if a larger inverter would be somehow less efficient than a smaller, closer to demand/load size unit? I am looking at 3.6, 4.0 and 5.5 sizes at this point.
Thanks in advance for any suggestions.
