MODULAR HIGH-VOLTAGE LITHIUM BATTERY SYSTEM
ET-51.2V100Ah-HV High-Voltage LiFePO4 Battery System
MODEL · ET-51.2V100Ah-HV
ET-51.2V100Ah-HV uses 51.2V 100Ah, 5.12kWh LiFePO4 modules in four-to-ten-module series configurations. The resulting 204.8-512V platform provides 20.48-51.2kWh nominal energy for indoor solar storage projects. It supports CAN and RS485 communication, 50A charge/discharge current and natural cooling. Inverter voltage window, protocol, protection design and module quantity must be selected as one engineered system.
Best suited to distributors, installers and system integrators needing a compact entry point into high-voltage storage without moving directly to a large commercial rack.
Technical values are based on the supplied LeforESS catalog and remain subject to the selected model datasheet.
Compact High-Voltage Project Fit
A 20.48-51.2kWh Platform for Smaller HV Projects
The 100Ah module is the lower-energy building block in the ET family. It fits projects where the required DC voltage is high but the total stored energy and current path remain moderate.
Commercial solar self-consumption
Configure four to ten modules around a compatible high-voltage inverter for daytime solar shifting and managed evening loads.
Critical-load backup
Use the project load profile and required runtime to select the module count; nominal energy alone does not establish backup duration.
Distributor system packages
Offer a defined battery family with a controlled voltage range while keeping inverter, protection and enclosure choices project-specific.

Product specifications and configuration options must be confirmed against the selected model datasheet before ordering. The current live page contains conflicting IP, warranty and stack-limit claims. Replace those claims only with the latest approved model datasheet; do not combine both versions.
Series-System Engineering
Voltage Matching Before Capacity Expansion
The module count determines system voltage as well as stored energy. That makes PCS selection, pre-charge behavior and protection coordination part of the initial quotation, not an after-sales adjustment.
Technical Buying Questions
ET 100Ah System Selection Questions
Can a single 5.12kWh module operate as the complete HV system?
The catalog defines a four-to-ten-module series system. The control architecture and inverter requirements must be confirmed for the selected module count.
Is the IP21 system suitable outdoors?
No outdoor claim should be made from an IP21 rating. Use a protected indoor location or a separately engineered enclosure.
Can modules be added later?
Expansion may be possible only after confirming module revision, state of health, voltage, control firmware and the approved series configuration. Do not mix unmatched modules.
Which inverter should be quoted?
Select an inverter whose battery voltage window, current capability and communication protocol match the final four-to-ten-module configuration.
