WEIDA 10 kW Three-Phase High-Voltage Home Storage System
A 10 kW, 380/400 V three-phase solar storage system with four to six stacked battery modules and a 14–22 kWh battery configuration range.
- System model
- HZ-TH-10KW-14.7KWh-H
- Rated AC output
- 10 kW
- AC supply
- 380/400 V, 3L/N/PE, 50/60 Hz
- Battery module

Product overview
The HZ-TH-10KW-14.7KWh-H combines a three-phase inverter with a high-voltage battery stack for solar self-consumption and backup. Choose the stack size against the load and battery current limits, then check the PV string voltage and grid connection.
Configuration note: nameplate values help define the starting point. Final usable energy, interfaces, operating limits, document scope, and commercial terms are confirmed for the specific project.

Applications to evaluate
Small-site solar and backup power
Validate the duty cycle, site, interfaces, and operating objective before confirming model suitability.
Selection, supply scope and engineering notes
- Specify the four-, five- or six-module stack and confirm the resulting power across its battery voltage window.
- Plan a protected indoor location, mounting stability and service space around the stack.
- Confirm the local grid approvals, backup circuits and inverter settings for the quoted version.
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.

What buyers ask before specifying a battery system
Answers cover the information needed to confirm configuration, operating conditions, documentation, price, and delivery.
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 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.
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.
