E mail or call Renogy an tell them what you want to accomplish, you do not have to buy their system to get the information, my Axis only came with 2 group 24 12 volt batteries, I added 4 100 watt solar panels, replaced the group 24 batteries with 4 gel cell an a 2000 watt inverter, I hard wired the inverter so every outlet is covered by the inverter, my coach is a 30 amp service and the inverter is rated for 30 amp pass through, if you do not have a full understanding of how a 120 volt AC system works you should get some one who does, I talk to people all the time who just go out and start buying components and wonder why they have problems,
