Huawei LUNA2000-7-E1 HV battery

Huawei LUNA2000-7-E1 – 6.9 kWh high-voltage LFP battery module

The Huawei LUNA2000-7-E1 is a 6.9 kWh high-voltage (HV) LiFePO₄ battery module that is the basic unit of the latest generation LUNA2000-7/14/21-S1 Smart String ESS systems. The module includes a built-in energy optimizer that monitors and maximizes available capacity at the cell level, ensuring that each battery module operates at its best efficiency.

The LUNA2000-7-E1 is ideal for residential and small business energy storage systems where high efficiency, safety, and long life are of paramount importance.

SOLARKIT reviews

The biggest advantages of Huawei's new LUNA2000 E1 series:

• 6.9 kWh module capacity → higher specific energy density than the previous S0 series
  
  
• Plug & Play installation – cable-free module connection
  
  
• 100% depth of discharge (DOD) → maximum usable energy
  
  
• IP66 outdoor protection → maximum resistance
  
  
• Super quiet operation (<29 dB)
  
  
• Active and passive charge equalization per module
  
  
• max. 4 towers can be connected in parallel (up to 82.8 kWh per inverter)

This module is ideal for any project where you are building a premium energy storage system with Huawei hybrid inverters (SUN2000-L1, M1, MB0 series, MAP0).

Can it be used in island mode?

Yes, the LUNA2000-7-E1 fully supports off-grid operation with Huawei hybrid inverters.

Compatible inverters:

• SUN2000-2/3/3.68/4/4.6/5/6KTL-L1
  
  
• SUN2000-8/10K-LC0
  
  
• SUN2000-3/4/5/6/8/10KTL-M1
  
  
• SUN2000-12/15/17/20/25K-MB0 (max. 4 ESS parallel operation supported)

In island mode, the power module (LUNA2000-10KW-C1) and the battery together provide backup and grid-off functions.
