5. Make sure the wires are securely connected. CAUTION: Appliances such as air conditioner required at least 2~3 minutes to spool up because it needs to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in a short period of time, it may cause damage to your connected appliances. - Page 11 Take the 250Wp PV module as an example. After considering above two parameters, the recommended module configurations are listed in the table below. Solar Panel Spec.

Page 26: Battery Equalization Description
Battery Equalization Description Battery equalization function is built into the charge controller. It reverses the buildup of negative chemical effects such as stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalization also helps to remove sulfate crystals that may have built up on the plates. If left unchecked, this condition, called sulfation, will reduce the overall capacity of the battery. -
Page 27: Fault Reference Code
However, in Equalize Mode, if the battery equalization timer runs out and the battery voltage doesn’t recover to the battery equalization voltage point, the charge controller will extend the battery equalized time until battery voltage achieves equalization voltage. If the battery voltage is still lower than equalization voltage when the extension runs out, the charge controller will stop equalization and return to the floating charging stage. -
