PSTACK Modular High-Voltage LFP Battery

High-voltage storage for larger home and business systems in Nigeria. PSTACK uses 5.069kWh nominal LFP modules, with 2–9 modules per stack. Choose the stack size from your load, backup target and approved inverter voltage range.

A compatible high-voltage inverter and approved BMS communication are required. PSTACK cannot directly replace a 48V battery.

High-Capacity & Scalable

Each PSTACK module provides 5.069kWh nominal energy at 70.4V. Connect 2-9 modules in series per stack (approximately 10-45kWh). The datasheet supports up to 10 stacks in parallel without an extra device, or up to 20 with an additional BAU and an approved system design.

High-Voltage Efficiency

Operates on a high-voltage platform, reducing energy losses, improving conversion eficiency, and supporting large hybrid and three-phase inverters.

Smart Battery Management

Advanced BMS with cell balancing, over-voltage, over-current, and temperature protections ensures safe, stable, and long-lasting performance.

Effortless Expansion

A modular stacking design supports capacity planning and later expansion. A qualified installer must confirm module count, inverter compatibility and the approved expansion procedure.

Seamless Integration

Use a compatible high-voltage inverter and an approved BMS communication configuration. Confirm the inverter voltage window, firmware and battery compatibility before purchase; PSTACK is not a replacement for a 48V battery.

Ideal for Demanding Installations

Large residential estates and commercial facilities

Off-grid and hybrid microgrids

Industrial energy backup

Projects needing modular high-voltage storage and a planned expansion path

Perfect for off-grid cabins, telecom sites, farms, and industrial backup

Backup runtime depends on usable battery energy and the connected load

IP65 enclosure protection, with installation and temperature limits specified in the product manual

Ask the installer to confirm electrical protection and safe service access

Smart Monitoring & OTA Updates

PSTACK integrates with Luxpower s monitoring platform for real-time status, performance tracking, and remote firmware upgrades, ensuring optimal operation and peace of mind.

Model selection

Planning with the PSTACK Modular High-Voltage LFP Battery System

Best fit

Larger Nigerian homes, offices and shops planning high-voltage storage, subject to a load assessment and inverter compatibility check. The Lagos, Abuja and Port Harcourt teams can help review the project.

Check before installation

Confirm compatible inverter, module count, operating voltage window, floor loading, isolation, protection and commissioning process.

PSTACK capacity and expansion

The April 2026 datasheet lists 5.069kWh nominal energy per module. Capacity labels below are rounded; select module count from the inverter voltage window as well as the energy target.

Modules per stack	Nominal energy	Nominal voltage
2	10.138kWh (10kWh class)	140.8V
3	15.207kWh (15kWh class)	211.2V
6	30.414kWh (30kWh class)	422.4V
9	45.621kWh (45kWh class)	633.6V

Up to 10 stacks can be connected in parallel without an extra device, or up to 20 with an additional BAU, subject to approved system design. More stored energy does not automatically increase inverter output power.

For local planning, start with your essential circuits, target outage hours and existing inverter. Compare PGEM low-voltage storage, review Nigeria installation examples, or request a PSTACK compatibility review.

FAQ

How much energy does one PSTACK module store?

One module has 5.069kWh nominal energy at 70.4V. A stack uses 2-9 modules, approximately 10-45kWh as labelled in the datasheet. Usable energy and runtime depend on operating limits, losses and the actual load.

Can I expand a PSTACK system later?

The datasheet permits 2-9 modules in series per stack, up to 10 stacks in parallel without an extra device, or up to 20 with an additional BAU. Expansion must be approved for the inverter, control hardware, firmware, module condition and site design.

Can PSTACK replace a 48V PGEM battery?

No. PSTACK is a high-voltage system. PGEM and PGEM PRO are low-voltage batteries. They are not interchangeable; check the inverter voltage window, BMS communication and approved battery configuration.

Where can PSTACK be used in Nigeria?

Consider PSTACK for a larger home or business site designed around compatible high-voltage storage. Send the Lagos, Abuja or Port Harcourt team your location, load list, inverter model and expansion target. The Nigeria case studies show other product combinations, not a confirmed PSTACK installation.

What does the PSTACK IP65 rating mean for installation?

The datasheet lists IP65 protection. The installer must still follow the manual for location, temperature, clearances, foundation, electrical protection and service access; the rating does not make the battery flood-proof.

Who should install PSTACK?

High-voltage battery systems should be designed and commissioned by qualified personnel with the correct protection, isolation and site handover process.

Where can I get PSTACK documents and support?

Use the download centre for the current datasheet or manual, check the warranty page, and send model, serial number, site photos or PDF files through the Nigeria contact form when you need technical support.
