-
Can EpowerHub BESS operate off-grid?

Yes. EpowerHub BESS can operate independently from the grid. Ensure reliable power supply in remote areas or during power grid outages.

-
What are the typical use cases for EpowerHub?

EpowerHub is ideal for remote or mountainous areas with limited grid access, factories or industrial sites with high electricity demand, and other locations requiring stable or temporary power supply.

-
Can I use PowerPack at home?

Yes. PowerPack can be used at home for single‑phase or three‑phase AC input, making it ideal for residential charging.

-
What connection methods are available?

PowerPack supports multiple plug‑and‑play connection options for flexible deployment: Air Switch Connection, Quick Plug Connection, Industrial Socket Connection.

-
Can PowerBoost chargers operate in extreme weather conditions?

Absolutely. PowerBoost is IP54-rated, with an operating temperature range of -30℃ to 65℃, so it works reliably in rain, snow, or heat.

-
How long does it take to charge an EV with PowerBoost?

Charging speed depends on your EV and the charger’s power configuration. For most EVs, 80% charge can be reached in 20–45 minutes with PowerBoost fast charging.

-
Can the energy storage system be used as a backup power source? What scenarios is it suitable for?

Yes, the EpowerHub energy storage system can serve as an emergency backup power source and, when needed, operate as the primary power supply.

In the event of a power outage or grid instability, it ensures the continuous operation of key equipment and systems. It is suitable for scenarios with high requirements for power supply continuity, such as hospitals, data centers, industrial parks, and logistics hubs.

-
What is an industrial charging solution? What industries are it suitable for?

Industrial charging solutions refer to efficient, safe and sustainable power supply systems for industrial application scenarios (such as construction sites, factory parks, and remote infrastructure).

Such solutions are suitable for application environments such as electric heavy equipment, construction machinery, and electric fleets, helping companies transition to sustainable operations without affecting productivity.

L2?L3?What are the different levels of chargers?

Level 1

The slowest option. An AC charger that plugs into a standard 120V wall outlet which can add 3 to 8 kms of range per hour. A full recharge can take 24 hours or more.

Level 2

Level 2 chargers are also AC chargers. The various types of Level 2 chargers are designed to handle either a 240-volt household outlet or a 208-volt commercial outlet. Level 2 chargers are smaller than Level 3 DC fast chargers and have a lower initial investment cost because fewer components are required.

Level 3

Level 3 chargers are DC chargers, which, unlike AC-based Level 1 and 2 chargers, output DC current to the vehicle. They convert AC to DC within the charger and bypass an EV’s onboard AC to DC converter, charging the battery directly. The higher the kW capability, the faster it will charge.

What is NACS?

North American Charging Standard (NACS) is a universal charging connector design that aims to simplify the driver experience by providing one type of connector for Level 2 and Level 3 (DC Fast) charging stations.

This will eliminate the need for multiple connector types (SAE J1772, CHAdeMO and CSS) by standardizing the connector design. The NACS connector is currently designed for use with Tesla vehicle ports. SETEC POWER's charging stations including DC chargers and PowerOnTheGo already support NACS connectors.
