Compare the displayed battery module and pack pages

Open an exact page for its source-derived configuration, then confirm the final capacity variant, battery-bank design, BMS and inverter pairing, accessories, files, installation, transport conditions, warranty, availability, and order terms.

Displayed battery architectures

Choose the DC architecture before comparing amp-hours or kWh

The current pages span four battery roles. A similar chemistry, nominal voltage, capacity, or module enclosure does not prove that products can be mixed, paralleled, placed in series, connected to the same inverter, or installed in the same environment.

12.8 V standalone LFP · 2.62 kWh

One 205 Ah page for selected 12/24/48 V off-grid, telecom, marine, or replacement projects. Series and parallel permission, charger profile, current, cables, fusing, enclosure, and BMS behavior need confirmation.

51.2 V low-voltage modules · 5.12–16.08 kWh

Six rack, wall, stand, and floor-enclosure pages with 100–314 Ah options. Compare current, mounting, IP rating, communications, parallel limits, inverter protocol, and exact capacity variant.

High-voltage rack · 43–241 kWh system ranges

One 153.6–768 V system page built from 51.2 V modules. Series count, PDU, rack, isolation, current, inverter window, CAN protocol, protection, and qualified commissioning form one approved package.

High-voltage stack · 30.72–241.15 kWh ranges

Two stack-system pages with different module capacities and minimum series counts. Final voltage, energy, PDU or control unit, mechanical stack, BMS protocol, inverter, and accessories must match.

Battery technical shortlist

Six checks before a battery module RFQ

A battery bank must be selected as an electrical, control, mechanical, thermal, safety, and documentation system. Nominal voltage and kWh are useful filters but cannot establish compatibility, runtime, installation suitability, or commercial warranty.

Application and battery-bank role

Define residential, off-grid, telecom, backup, C&I, replacement, or expansion use; required power, usable energy, autonomy, duty cycle, grid or generator behavior, and future expansion.

Chemistry, voltage and configuration

Confirm LFP chemistry, nominal and operating voltage, module count, series or parallel rules, PDU or master control, DC isolation, pre-charge, protection, earthing, and compatible inverter window.

Energy, current and operating limits

Review Ah, nominal and usable kWh, recommended and maximum charge/discharge current, C-rate, DoD basis, temperature limits, derating, cell balancing, reserve, and load peaks.

BMS protocol and approved pairing

Match CAN or RS485 protocol, pinout, firmware, inverter battery profile, master and slave addressing, parallel or series control, alarms, shutdown behavior, monitoring, and written compatibility evidence.

Mechanical and installation design

Confirm dimensions, mass, rack or wall loading, stack hardware, IP class, indoor or outdoor enclosure, ventilation, clearance, cable route, terminals, lifting, seismic restraint, access, and service replacement.

Safety, transport and commercial files

Request exact-model datasheet, manual, label, SDS, UN 38.3 evidence where applicable, certificates, warranty terms, cycle-test basis, packing, dangerous-goods details, origin, serial traceability, and order revision.

Battery evidence boundaries

Keep battery-module data separate from system performance and approval

The displayed pages are source-derived battery configurations. Final model variant, bank design, inverter pairing, BMS firmware, enclosure, protection, installation, transport acceptance, warranty, availability, and commercial terms require exact-project confirmation.

A battery module is not a complete ESS

Inverter or PCS, protection, isolation, PDU, rack or enclosure, EMS, switchgear, cooling, fire strategy, cables, installation, commissioning, and local approvals may be separate.

kWh is not guaranteed backup duration

Runtime depends on usable DoD, load profile, surge, inverter and cable losses, reserve, temperature, aging, BMS limits, charge state, auxiliary loads, and operating strategy.

Cycle-life test data is not the warranty

A cycle figure applies to stated temperature, C-rate, DoD, end-of-life threshold, test method, and configuration. Commercial years, throughput, exclusions, remedies, and claim process require warranty terms.

UN 38.3 is not installation or shipment approval

Transport evidence has a defined product and test scope. Carrier acceptance still depends on model, quantity, packing, route, mode, documents, and current instructions; site safety and electrical approval are separate.

Continue the battery review

Connect battery selection to compatibility and system objectives

Use the solution page to define loads and backup purpose, then use the compatibility guide to verify voltage, current, protocol, firmware, protection, and approved pairing before selecting a module bank.

Residential solar and essential backup

Define critical loads, autonomy, PV, inverter role, battery usable energy and power, protection, installation, documents, and supply responsibility before sizing modules.

Review backup solution

Battery and inverter compatibility checks

Review voltage window, charge and discharge current, CAN or RS485 protocol, firmware, approved list, protection, cables, commissioning, and written pairing evidence.

Battery module FAQ

Questions to close before selecting battery modules

These answers establish an RFQ starting point. Final bank engineering, inverter compatibility, protection, enclosure, installation, transport, local approval, commissioning, and warranty review remain project-specific.

Can two 51.2 V LFP batteries work with the same inverter?

Not automatically. Compare the exact operating voltage, recommended and maximum current, CAN or RS485 protocol and pinout, firmware, inverter battery profile, approved-model evidence, capacity, parallel control, protection, cables, alarms, shutdown behavior, commissioning settings, and warranty conditions.

How should low-voltage and high-voltage battery architectures be compared?

Start with the inverter DC window and system design. Compare series or parallel arrangement, module count, current, power, PDU or master controller, BMS protocol, isolation, protection, cable size, enclosure, installation qualification, service strategy, usable energy, and expansion rules—not nominal voltage alone.

Does a 10 kWh battery provide 10 hours of backup?

Only under an unrealistic constant 1 kW assumption with no losses or reserve. Real runtime depends on usable DoD, inverter efficiency, load variation and surge, battery power limits, temperature, aging, BMS reserve, state of charge, cables, and auxiliary consumption. Use a load schedule and operating objective.

What should a battery module RFQ include?

Include application, load power and energy objective, inverter make and model, low- or high-voltage architecture, capacity and expansion target, quantity, series or parallel plan, BMS protocol, installation environment, rack or enclosure, protection, required datasheet and transport files, destination, warranty request, and delivery target.

Battery Modules and Packs for Low- and High-Voltage Storage RFQs

Compare 10 displayed LFP battery module and pack pages spanning 12.8 V standalone, 51.2 V low-voltage rack and enclosure, and high-voltage rack or stack architectures. Review the exact model for capacity, nominal energy, operating voltage, charge and discharge current, series or parallel limits, BMS communication, dimensions, mass, installation environment, cycle test conditions, transport evidence, and compatible inverter requirements before defining a battery bank.

Prepare a battery module RFQ from the DC architecture

Send the application, load and autonomy target, inverter, voltage architecture, kW/kWh, module count, BMS protocol, installation, enclosure and protection, documents, destination, quantity, and schedule. Final compatibility, model, price, availability, warranty, and lead time are confirmed in the quotation.
