12 Copyright | NZS Installation and Operation ManualCCS Combo 2 different current varieties are available to choose. There are three kinds of current level to use 200A, 250A and 300A. Of which, 250A and 300A cables can support up to 400Afor certain period based on ambient temperature and connector temperature. For each, cable length is free to be customized from 3m to 10m.The usable DC-Power on a DC-outlet is limited by the maximum current of the used DC-charging cable. The effective current carrying capacity of the charging interfaces is spec-ified on the nameplate.Net Zero Series is by default configured with a cable length of 5m. It can offer at least 4.4m cable radius at the height of ground level covering the parking space.Charging Connectors4.4m 4.4m

2.3 Applicable scenarios3.1 PackageBecause of low input requirement, NZS is flexible to be applicated in varies scenarios:
Highway refueling stations: Due to remote location, there is only limited power supply condi-tion at refueling stations on highway. NZS only needs max. 70kW for input and output more than 200kW, which realize fast charging demand on highway. Commercial Center: In case of a large price difference between day and night, NZS supports charging battery with low price and discharge power to vehicle during peak hours, which significantly increase profit for CPOs.Retails: Industrial socket simplify cable connection procedure.
Copyright | NZS Installation and Operation Manual 13/ Package and Transportation3.0Net Zero Series is packed in recyclable wooden Package (PLYWOOD). Charger unit, ESS unit and basement are packed separately in 3 packages. Following are package pictures for charger unit (left) and ESS unit (right) with their dimen-sions. Charge package is formed from a wooden pallet and 5 pieces of wooden boards. Different with Charger unit, center-of-gravity for ESS shifts to the front of system. To ensure transportation safety, instead of wooden pallet, ESS package is formed from a metal pallet and 5 pieces of wooden boards.
