Seeing some posts about using a resistor to pre-charge (the capacitors?) the inverter. I have an MPP 2424LV-MSD that I hope to have batteries for in the next few days. I have seen lots of differing opinions on the subject. I read in one place that if the inverter is small, under 3000 watts was their threshold, there is no need. The manual for the MPP does not mention it and as well I have seen Will just touch the cable to the battery and let 'er spark. I have a circuit breaker so I will not need to go through that, but I want to be as kind to my unit as possible. I have also noticed that the resistor values suggested are all over the place as far as ohms and watts. I have an old piece of electrical equipment that has a 5w 5ohm resistor. Can I use that? Is it just a matter of how long it will take to pre-charge? I am using (2) 12v 100Ah batteries in series with 2 gauge cable. (Originally purchased 2/0 cable but soon learned that the 2424LV will only accept 2 gauge max.) I should only be using about 16"-20" for the individual pos and neg terminals to the 2424LV. Any information would be appreciated.
