High-Voltage Stackable LiFePO4 Battery (51.2V 100Ah Modules, 204.8V+ Stacks)

LJY-HV51100-STACK high-voltage stackable LiFePO4 battery with 51.2V 100Ah modules, front view, white background — Appearance, color and logo customizable per customer request.

Product Overview

A high-voltage (HV) stackable LiFePO4 battery system made of 51.2V 100Ah (5.12kWh) modules connected in series under a high-voltage BMS / control box. Typical stacks start at 4 modules (204.8V, 20.48kWh) and grow module by module. It is designed for HV hybrid inverters that are now common in EU, AU and other residential and light-commercial markets.

Distributors and installers re-order the same module SKU project after project, so the module, the control box and the communication setup are the repeat-purchase items. This page is different from our low-voltage stackable 51.2V home storage, where modules are connected in parallel at 51.2V.

Appearance, color and logo customizable per customer request.

Specifications

How to read Status — three classes: [Industry reference] = standard reference parameter common to this product class (not an LJY test result). [Optional configuration] = configurable per OEM/ODM project (BMS communication, parallel/series setup, heating, enclosure, logo). [Confirmed per project] = fixed only in the datasheet issued with your quotation. Arithmetic: energy = nominal voltage × Ah.

Distributor FAQ

Can I order a 153.6V 100Ah (3-module) high-voltage stack in bulk?

Yes, if your HV inverter's battery-voltage window accepts it: 3 × 51.2V 100Ah modules = 153.6V, 15.36kWh (arithmetic). The module count per stack and the HV BMS are confirmed against the inverter model and firmware per project; quantity, price and lead time are confirmed per order.

Is the HV stackable battery for sale to installers and distributors?

Yes. We supply it to ESS integrators, installers and distributors as an OEM/ODM build, with private label available. It is not sold as a retail single unit; each order starts from the inverter and site data in the RFQ.

Do you also supply low-voltage stackable systems?

Yes. For 48V-class (51.2V) inverters, see stackable LiFePO4 home energy storage; LV stacks are paralleled rather than series-connected, and the BMS/inverter pairing is confirmed per project.

Optional configurations (OEM/ODM)

LJY Energy supplies this model as an OEM/ODM configurable build. The items below are configured per customer project — they are not fixed catalog defaults.

BMS communication: CAN/RS485 protocol set to your HV inverter — confirmed per project.
Series configuration: module count to match the inverter battery-voltage window.
Parallel stacks: configured per project; no fixed maximum is published.
Self-heating: available on request, to be confirmed per project.
Enclosure & branding: housing colour, logo, labels, packaging — Appearance, color and logo customizable per customer request.

BMS, communication & protection

In an HV stack, the BMS/control box handles pre-charge, isolation and contactor control as well as cell protection. It must match the inverter voltage window and protocol.

BMS sizing guide

Load / use case	Suggested BMS rating
HV hybrid inverter, home	Module count set to inverter battery-voltage window
Light commercial	Parallel stacks per project design
Cold sites	Add self-heating option (to be confirmed)

Never assume brand-level compatibility. Send the inverter model and firmware; protocol and settings are confirmed per project.

Size, handling & fitment

Stacked modules sit on a base and are connected in series; plan floor load, wall anchoring and front clearance per the installation manual for your build.

HV DC requires qualified installation; follow local electrical rules.

Frequently Asked Questions

HV or LV — which should I choose?

Choose by inverter: HV hybrid inverters need an HV stack; 48V inverters need a 51.2V (48V class) battery. For current, cabling and minimum stack size side by side, see our high-voltage vs low-voltage battery storage guide.

How many modules can I stack?

The module count is set by the HV BMS and the inverter voltage window and confirmed per project.

How is MOQ set?

MOQ is confirmed per project stage (sample, pilot, production) and depends on cells, enclosure tooling and branding scope.

Which certificates apply?

Certificate scope is confirmed per model, order and target market. We do not claim certifications on this page.

Is it compatible with my inverter?

We do not publish a compatibility list. Communication protocol and settings are confirmed against your exact inverter or PCS model and firmware per project.
