I am planning to supplement the generator use at my small vacation home with a solar system and batteries. It tends to get hot in the summer, so we occasionally run an AC unit. By my estimates my loads will draw about 3000 watts (W), but the AC has a surge startup demand that would put the total draw near 6000W. I haven't made any decisions regarding my battery bank yet
Is the SW 4024 or 4048 better suited for my application?

Hi Anon
Based on the information you provided we would suggest using the SW 4048. Both the 4024 and 4048 are unique in that they offer significant surge power ratings of 7000W for 5 seconds.
SW4024
Maximum continuous output power (AC): 3400W
Max 30 minute output power (AC): 4000W
Max 5 second power surge rating (AC): 7000W
SW4048
Maximum continuous output power (AC): 3800W
Max 30 minute output power (AC): 4400W
Max 5 second power surge rating (AC): 7000W
Based on this information both units would support your AC surge load, but the SW 4048 will give you more wiggle room in terms of continuous power output. If you go with the SW 4048 you will need to configure a 48V battery bank. A 48V battery bank will keep your amps lower, allowing you to use smaller conductors and fusing/breakers.
