* Faults will self-recover when the condition returns to normal range
** If the AC limit is set to 0 A, there will be no current available and the charger will not operate, but bypass will
still function. This fault will self-recover when the setting is changed to >0.
*** The inverter/charger must be sent back to the factory for evaluation.
**** Faults may be due to a short-circuited output or a low or weak DC voltage source.
