NON ESSENTIAL LOAD (NEL) TRIP
When controller detects generator over power, over current, it can trip some non-essential loads to
realize self-protection. There are 3 NELs trip, the priority is NEL1>2>3 (NEL1 trips first). If the active
power or current has exceeded the set value, the corresponding NEL will trip after the trip delay, and the
warning alarm will be initiated. NEL trip can be reused after alarm response only.
