Configured from three 48V 100Ah LiFePO4 modules
The 14.4 kWh Low Voltage Battery Bank is a larger residential ESS configuration built around three scalable 48V 100Ah deep-cycle LiFePO4 modules. It fits homeowners and installers who need more overnight storage, longer backup time, or a stronger solar self-consumption battery bank.
Smart BMS monitoring
Built-in smart BMS supports remote monitoring, protection, and stable operation across the expanded battery bank.
Maintenance-free storage
Cobalt-free LiFePO4 chemistry helps reduce maintenance while supporting safe deep-cycle solar storage.
Expansion-ready design
Parallel expansion support lets the battery bank grow as household load, backup time, or solar capacity increases.

Buyer checklist for residential solar storage
A 14.4 kWh battery bank is often selected when the home needs longer backup time or more daily solar self-consumption than a starter low-voltage battery bank can provide.
Best-fit scenarios
- Residential solar self-consumption and extended backup energy storage.
- On-grid homes that need stronger battery support during peak tariff periods.
- Off-grid cabins or homes with higher daily load requirements.
- Emergency backup for lighting, network, refrigeration, and essential circuits.
Confirm before ordering
- Inverter brand, low-voltage range, and communication protocol.
- Backup loads, peak power, and target autonomy hours.
- Installation space, ventilation, wall/cabinet mounting, and cable routing.
- Certification documents, warranty terms, and expansion plan.

FAQ
Why is it called 14.4 kWh?
It is typically configured from three 48V 100Ah modules. Each module is about 4.8 kWh, giving a 14.4 kWh nominal battery bank.
Can the system expand later?
Yes. The 48V module platform supports future parallel expansion, subject to inverter compatibility and installation design.
Is it suitable for off-grid solar?
Yes. It can be used for off-grid solar when the inverter, load profile, charging source, and backup time are properly sized.
