Applications to evaluate
Residential solar storage
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Small office or shop backup
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Modular off-grid battery banks
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Review the application requirements
Selection, supply scope and engineering notes
- Confirm inverter voltage, charge settings, CAN or RS485 compatibility, and the approved module count.
- Calculate runtime from usable energy and measured loads, including inverter losses.
- Allow for the rack or cabinet, cable, fuse or breaker, ventilation, and service-access requirements.
- Confirm warranty, approved expansion topology, protective devices, and applicable compliance documents in the quotation.
Confirm the project responsibility matrix
The product rating does not define a turnkey project scope. The quotation should identify who supplies, integrates, installs, commissions, and accepts each applicable item.
- Battery system, BMS, thermal management, enclosure, internal protection, and communications
- PCS, EMS or SCADA, transformer, switchgear, metering, external protection, and grid interface
- Fire strategy, foundations, lifting, cable routing, installation, testing, and commissioning
- Documentation, training, spare parts, warranty conditions, maintenance, and acceptance records
Technical documents
Use the public page and any available procurement brief for initial comparison. Request the applicable controlled data sheet, drawings, test or certificate evidence, and commercial documents for the exact quoted model and destination.
Guides for your technical review
Home Battery Sizing
Size a home battery from the loads that must run, their coincident and starting power, required backup hours, usable-energy assumptions, recharge opportunity, and the inverter's supported battery configuration.
Read guide →Home Battery Formats
Rack, stacked, and wall-mounted batteries mainly differ in mechanical format, expansion method, service access, footprint, cable routing, and integration. Energy needs and inverter compatibility remain the first filters.
Read guide →Solar Battery Decision Guide
A solar battery is worth evaluating when it supports a defined objective that can be modeled from interval loads, solar production, outage needs, export limits, tariffs, and operating constraints.
Read guide →Frequently asked questions
What buyers ask before specifying a battery system
Answers cover the information needed to confirm configuration, operating conditions, documentation, price, and delivery.
How is a battery sized for a solar project?
Sizing starts with interval load data, photovoltaic production, desired backup loads, outage duration, export limits, tariff periods, and the operating objective. Oversizing from monthly consumption alone can produce a poor technical and commercial result.
Can a home battery back up every household load?
Only if the inverter power, battery energy, surge requirement, wiring, and changeover design support those loads. Critical-load backup and whole-home backup are different designs and should be specified separately.
How do rack-mounted, stacked, and wall-mounted home batteries differ?
They primarily differ in installation format, expansion method, service access, footprint, and system integration. Select the format after checking space, inverter compatibility, required energy, cable routing, and local installation rules.
Can the battery system be customized?
Configuration review can cover voltage, capacity, enclosure, communications, thermal management, and system interfaces. Any customization is subject to engineering review and is confirmed in the final technical proposal, not assumed from a family page.
Which certifications are available?
Certification scope varies by model and destination. Request the current certificate and test-report package for the exact quoted model.
Why are prices not published on the product pages?
The listed products are project-configured B2B systems or battery series. Pricing depends on configuration, quantity, accessories, packaging, destination, and commercial terms, so quotations are prepared against a defined project scope.
