If you opt for the upgraded control panel (and I highly recommend it), errors will be output as actual text messages on the LCD display. Also, you can adjust a TON of inverter options like setting the voltage at which it cuts off to save your batteries from going below 50%, etc.
And adding the Battery Monitoring Kit also, gives you a really fine 12v power system. With the BMK, it even reads out the SOC (State of Charge) of your batts as a percentage of total capacity. Great for insuring you don't go below the "magic" 50% level.
