NO TICE
● This document uses the EMMA-A02 as an example to describe electrical
connections. The EMMA-A01 supports only the PV and ESS features. Therefore,
do not connect signal cables of chargers, heat pumps, and other intelligent
electrical equipment to the EMMA.
● The minimum cable cross-sectional area must meet local standards.
● The factors to be considered in cable selection include the rated current, cable
type, routing mode, ambient temperature, and maximum acceptable line loss.
