Yeah of course. But those other setups are absolute trash. Especially if hes worried about a hurricane. There wont be any solar available before those dinky 600 and 1k systems are spent. Terrible value relative to a simple inverter group 31 setup and inverter setup. Way more ah, way more scalability (two 31s in parallel) or simply changing out the battery or charging it on your car. A 2k inverter can run ALOT of equipment if needed. Those linked systems cant do that in addition to no capacity.Your trolling motor battery shouldn’t be run past 50% capacity. You probably didn’t have much more life in it last your repair job
FYI I have a big blue cellpowa 600 running my return pump on my 75g reef. It’s a 300$ power station that I got on sale near a holiday for $250
I unplugged it from the wall to simulate an outage
