Sometimes small systems are plenty
Friday my wife suddenly got the urge to camp. Immediately. All the TT has is the original Group 24 battery, 5w solar to maintain it and a 700w/1500w inverter I've never even run under significant l...

AC to 72. Ahhhhhh.
Actually what I need to run the Microwave the way we use it is first and foremost AMPS, given I'm not cooking a turkey but mostly warming up food from the fridge. Others may use theirs differently.
AGMs generally have a huge advantage running high inverter loads like a microwave. Amp hours are not amp hours and not all the same to an inverter. Watts are watts though. The voltage profile of most AGMs means that their amp hours are delivered at higher volts, meaning they drain slower (because of making the watts with more volts and fewer amps) for a fixed number of watts provided to an inverter.
Their internal resistance is generally lower as well (especially in parallel vs series or series parallel) which means lower Peukert losses for a given load from a given amp hour rated bank.
Lastly they have more useable amp hours on an inverter than many non-AGMs. My AGMs stay above 11.0 volts down to 90% discharge for most currents, which means I can use the inverter at any point in the discharge cycle, not just a portion of the way through.
