Growatt split-phase off-grid procurement review
Growatt SPF 4000-18000T DVM-MPV Off-Grid Inverters
The current Growatt catalogue identifies the SPF 4000-18000T DVM-MPV split-phase low-frequency off-grid family. Its public record supports dual-voltage output, surge capability, multiple source/mode support, lithium/lead-acid/GEL routes, monitoring and a built-in low-frequency transformer. The record provides feature text and three linked files but no embedded member table. Use the exact model and project configuration rather than transferring a neighboring product's specifications.
Current catalogue boundary: The record provides feature text and three linked files but no embedded member table. The broad range requires member-level PV, battery, charger, split-phase/load, surge-duration, generator, transformer and parallel evidence.

Current document status
Before quotation, request the exact current datasheet and manual, released model/configuration schedule, electrical and performance tables, compatible-device matrix, wiring and protection design, firmware, destination evidence, warranty, packing and included accessories.
Current catalogue evidence
Preserve the split-phase off-grid identity and configuration boundary
The record supports initial research; exact ratings, compatibility, availability and destination acceptance remain controlled evidence.
Displayed identity
the SPF 4000-18000T DVM-MPV split-phase low-frequency off-grid family
Published feature set
dual-voltage output, surge capability, multiple source/mode support, lithium/lead-acid/GEL routes, monitoring and a built-in low-frequency transformer
Connected-system boundary
The broad range requires member-level PV, battery, charger, split-phase/load, surge-duration, generator, transformer and parallel evidence.
Evidence quality
The record provides feature text and three linked files but no embedded member table.
split-phase off-grid RFQ inputs
Six checks before fixing the exact model and system BOM
Duty, electrical interfaces, connected equipment, environment and documents must map to one released configuration.
Exact model and status
State full model/suffix, hardware revision, quantity, destination and whether the product is currently released, orderable and supported for that market.
Required operating duty
Define application, continuous/peak duty, operating hours, load or hydraulic profile, backup/transfer needs, energy objective and environmental conditions.
DC, PV and battery inputs
Provide module/string or battery configuration, voltage/current windows, module count, BMS protocol, firmware, temperature and protection requirements where applicable.
AC, load or equipment interface
Define phase/voltage/frequency, circuit or pump/motor data, service/generator route, transformer/neutral/earthing, breakers, cables and site constraints.
Controls, communications and accessories
Confirm meters/CTs, loggers, gateways, sensors, level probes, transfer/parallel hardware, app/backend, firmware, data ownership and fail-safe behavior.
Evidence and commercial control
Request current technical tables, compatibility and certificate schedules, SLD/wiring, warranty, acceptance tests, included BOM, packing, lead time and substitution rules.
Release, compatibility and performance boundaries
Do not convert catalogue positioning into an unconditional specification
The released exact model, operating conditions, connected equipment and destination documents remain controlling.
Current evidence is scoped
The record provides feature text and three linked files but no embedded member table.
System boundary remains project-specific
The broad range requires member-level PV, battery, charger, split-phase/load, surge-duration, generator, transformer and parallel evidence.
Headline performance needs conditions
Efficiency, cycles, warranty, backup, surge, expansion, temperature, charging, MPPT, communication and safety claims require the exact model, test conditions and current document schedule.
Availability and compatibility are separate
A visible or coming-soon page does not prove stock, production release, price, approved pairing, destination compliance, warranty or order acceptance.

Questions to close before technical approval and quotation
Every answer should reference the exact released model, configuration and destination.
What does the current catalogue confirm?
It identifies the SPF 4000-18000T DVM-MPV split-phase low-frequency off-grid family and supports dual-voltage output, surge capability, multiple source/mode support, lithium/lead-acid/GEL routes, monitoring and a built-in low-frequency transformer.
Is every detailed rating proven?
No. The record provides feature text and three linked files but no embedded member table.
Can neighboring family data or compatibility be assumed?
No. The broad range requires member-level PV, battery, charger, split-phase/load, surge-duration, generator, transformer and parallel evidence.
What should the RFQ include?
Include exact model/status, operating duty, DC/PV/battery and AC/load interfaces, controls/accessories, environment, destination evidence, quantity and acceptance requirements.
