After watching Will's videos and reading his discussion of the MPP all-in-one systems I clicked the link to purchase a PIP-2424LV-MSD Solar Inverter (MPP USA 24V 2.4 kW PIP). I also purchased all of the recommended Windy Nation cables through Amazon, so assumed that when I got ready to build my system I would be good to go. When I popped the cover on the bottom of the MPP to begin the assembly, however, what I found was somewhat different than what I expected. The manual that came with the unit is for a LV 3KVA-24V Inverter/Charger. Is this simply a newer model of what I ordered or was I sent the wrong item? I've never assembled anything solar, so I'm more than a bit hesitant to forge ahead until I'm sure I'm not going to end up with something that's not right for my application. Thanks in advance!
