Huawei LUNA2000 7 kWh LiFePO4 S1 battery
The Huawei LUNA2000-7-E1 (S1) battery module has a rated capacity of 6.9 kWh with LiFePO4 technology. Storage for photovoltaic systems, compatible with Huawei inverters, robust and expandable to increase self-consumption. Weight 68 kg.
The Huawei LUNA2000-7-E1 battery module (S1 series) is a lithium iron phosphate (LiFePO4) storage unit with a rated capacity of 6.9 kWh, for residential photovoltaic systems. It is designed to increase system self-consumption and is expandable to match the household's energy needs.
Why add LUNA2000 storage?
With the LUNA2000, solar energy produced during the day and not used immediately is stored and reused in the evening, raising self-consumption and reducing grid imports. LiFePO4 chemistry ensures high safety and long cycle life, ideal for everyday home use.

Frequently asked questions
Which inverters is it compatible with?
The LUNA2000 is designed for Huawei SUN2000 hybrid inverters. Make sure your inverter is hybrid/battery ready before purchase.
What is the difference from the 5 kWh module?
Capacity: the LUNA2000-7-E1 offers 6.9 kWh versus the 5 kWh of the base module, to cover higher evening needs. Both use the same LiFePO4 technology and the same modular approach.
Is LiFePO4 technology safe?
Yes. Lithium iron phosphate is among the safest and most stable lithium chemistries, with high resistance to overheating and long life: it is the standard for home storage.
How much does it weigh and how is it installed?
The module weighs 68 kg: installation must be carried out by a qualified technician, with the module fixed on a stable base and connected to the Huawei hybrid inverter according to the manufacturer's instructions.
What should be checked on delivery?
Check that the packaging, model and supplied items match the order and show no visible damage. Keep the manual and documents, and do not energise the product if the enclosure or connectors are damaged.
