I am finally looking to finish my solar and Lifepoe4 install on my 5th wheel. I have already installed 1380 watts of solar and a Midnite Solar Classic 250v SCC. I My plan is to use a Samlex EVO-4024 with Lifepoe4 24v bank, and have a separate 12v Lifepoe4 bank for my 12v Hydraulic jacks, electric cord reel, furnace fan and lighting. The jacks and cord reel draw about 115 amps when setting up and breaking down camp. I originally planed on using a step down converter, but I am thinking a separate system might offer a little better way to make sure I always have power to the essentials. Everything is basically already there except the new 12v batteries. Is this a bad idea?
