Compare the 12 displayed Techfine hybrid inverter pages

Open the exact series page, preserve its rating and configuration, then confirm current electrical data, battery pairing, grid/backup behavior, assembly scope, documents, availability and terms.

Displayed hybrid routes

Separate enclosure, control and phase architecture before comparing power

The catalogue includes complete inverter families and one SKD circuit-board route. Treat every series as a distinct electrical configuration.

XA, QA and TD families

Displayed source names span 3.6–11 kW-class labels and mention different IP, MPPT, CT/zero-export, PV-current and dual-output features. Confirm the exact rating, electrical table, firmware and included CT/accessories.

BH, EA and GA PRO families

Multiple pages share family names but differ by rating and MPPT wording. Keep the full page/model identity and verify PV inputs, battery interface, AC outputs, charging priorities, load terminals and options.

IV and KA routes

IV pages emphasize protection-related wording; KA is displayed as an 18/33 kW three-phase route with six-MPPT wording. Confirm actual phase/voltage, PV/current, battery/DC architecture, grid and project-level protection.

Inverter circuit-board SKD

The 3–11 kW SKD page is not automatically a finished certified inverter. Define supplied PCB/boards, enclosure, HMI, wiring, cooling, firmware, assembly, test fixture, quality control, compliance and final-product responsibility.

Hybrid inverter RFQ checks

Six checks before shortlisting a Techfine hybrid inverter

A reviewable RFQ ties an exact series to the site's PV, battery, AC/grid, backed loads and required evidence.

Operating mode and load boundary

State self-consumption, grid/zero-export, backup, off-grid, generator or another mode; provide continuous and peak loads, motors, critical circuits, transfer expectations and loads excluded from backup.

PV and MPPT design

Provide module data, temperatures, string length/count and orientations; verify cold Voc, hot Vmp, Isc/Imp, maximum PV voltage/power, MPPT window, current per tracker and string allocation.

Battery and charging interface

Provide chemistry, exact battery/BMS model, nominal/operating voltage, usable energy, charge/discharge current, protocol, firmware and approved pairing; define utility/PV charging priorities and generator charging.

AC, grid and phase

Confirm destination, single- or three-phase, nominal voltage/frequency, neutral/grounding, service/generator input, grid or anti-backflow requirements, output terminals and local electrical/grid evidence.

Parallel, protection and controls

Confirm permitted unit count and accessories, shared battery/AC topology, meters/CTs, bypass/transfer, isolation, breakers/SPD, communications, settings, firmware and commissioning sequence.

Assembly, files and supply

Request exact datasheet/manual, model/label, certificate/test scope, warranty, accessories, packaging and serial traceability; for SKD define supplied parts and QA, then confirm MOQ, samples, lead time and substitution.

Compatibility and scope boundaries

Hybrid wording does not define a complete approved solar-storage system

Final operation depends on exact model, firmware, battery, PV design, AC/grid, protection, assembly and destination rules.

Battery labels do not prove compatibility

Lithium activation, charging or communication wording does not approve every lithium or lead-acid battery. Confirm voltage/current, charge profile, BMS protocol, firmware and written pairing.

Zero-export and dual-output need a system design

CT location/direction, meter/control loop, firmware, load wiring, output ratings and fail-safe behavior determine anti-backflow and backed-load results. A feature line is not a commissioned design.

Parallel and surge claims are model-specific

Permitted quantity, continuous/peak duration, communication, battery arrangement, generator/bypass and protection must come from the exact manual and tested configuration.

SKD is not a finished-product approval

A circuit board or SKD supply leaves enclosure, thermal, insulation, wiring, firmware control, production tests, labels, certification, warranty and end-product liability to an explicitly assigned party.

Techfine hybrid inverter FAQ

Questions to resolve before fixing a hybrid series

These answers organize procurement; final electrical design, battery approval, grid/backup behavior and commissioning remain model- and project-specific.

Are Techfine hybrid inverter families interchangeable at the same kW?

No. XA, QA, TD, BH, EA, IV, GA PRO and KA can differ in phase, PV/MPPT voltage and current, battery interface, AC outputs, protection, controls and firmware. Compare the exact rating and source table.

Does lithium battery support mean any lithium battery can be connected?

No. Confirm voltage and current windows, charge profile, BMS protocol, firmware, approved model list, cables/protection and written pairing. Auto-restart or activation wording does not prove universal compatibility.

Is the Techfine inverter circuit-board SKD a complete inverter?

Treat it as a manufacturing supply scope unless the quotation explicitly includes a finished assembly. Define boards, enclosure, display, wiring, cooling, firmware, test fixtures, assembly, certification, labels, QA, warranty and end-product responsibility.

What should a Techfine hybrid inverter RFQ include?

Include destination, exact series/rating, phase/voltage, module/string plan, battery/BMS, operating and backup loads, grid/CT/generator/parallel needs, assembly scope, documents, quantity, samples, delivery target and substitution rules.

Techfine Hybrid Solar Inverters Across Nine Displayed Product Routes

Compare 12 displayed source pages covering XA, QA, TD, two BH, two EA, IV, an inverter circuit-board SKD, two GA PRO and one KA three-phase route. Family names and headline kW do not establish the same PV, battery, AC, backup, grid or parallel architecture. Preserve the exact series and rating, then confirm PV voltage/current and MPPT layout, battery voltage/current and communication, AC phase/voltage, load and surge duty, grid/zero-export or backup behavior, generator/parallel scope, protection, firmware, complete assembly and accessories, destination documents, availability and commercial terms.
