Current document status
Request the exact model/suffix, nameplate, manual, PV/battery settings, wiring diagram, protection schedule and destination evidence before quotation release.
Current table evidence
Keep power, battery and AC rows on the same selected member
An off-grid inverter must be selected against actual loads, PV strings, battery current and site wiring.
Member route
400–1,600 W table members; 12/24 V routes; PWM charger
PV and charger
Confirm MPPT or PWM type, PV cold Voc, operating window, PV watts, charge current and each exact-model limit.
Battery route
Confirm nominal voltage, chemistry, BMS/current limits, charge settings, temperature and the exact approved battery configuration.
AC and load route
Confirm input/source, output voltage/phase, continuous and surge loads, generator, transfer/bypass behavior, neutral and grounding.
Off-grid RFQ checks
Six checks before finalizing the inverter
Define the whole electrical route rather than selecting from a headline VA or watt number.
Exact code
Request model/suffix, nameplate and the applicable table row.
Load duty
List continuous watts/VA, power factor, motor start current, surge duration and critical circuits.
Battery
Fix voltage, chemistry, capacity, BMS, charge/discharge current, reserve and temperature.
PV
Provide module data, cold Voc, series/parallel layout, charger type and protection.
AC source and output
Confirm voltage, frequency, phase, generator, bypass/transfer, outlets and wiring.
Evidence
Request manual, wiring, settings, protection, supplied accessories, compliance evidence, warranty and commercial terms.
System boundaries
An inverter charger is not a complete off-grid system
Final performance and safety depend on the selected member plus PV, battery, load, protection and installation design.
Family boundary
Do not transfer watts, PV input, battery voltage, transfer time or optional functions across family members.
Battery compatibility
Voltage or lithium wording does not prove BMS pairing, current limits, charge settings or warranty approval.
PV and protection
Rated PV watts do not replace cold-Voc, MPPT/PWM, string protection, cable, isolator, SPD and grounding checks.
AC behavior
UPS, bypass, split-phase and generator labels require the exact manual and a load-specific acceptance test.

Record real loads, battery and PV inputs before asking for a final configuration.
Off-grid inverter FAQ
Questions to close before quotation
The exact member and installation design remain decisive.
Which rating applies to this VS 400–1600 W PWM off-grid inverter?
Use the exact quoted model and its table row. The current family record is 400–1,600 W table members; 12/24 V routes; PWM charger.
Can any same-voltage battery be used?
No. Confirm battery chemistry, BMS, current, charge settings, temperature and exact-model approval.
Does the inverter headline prove backup or generator compatibility?
No. Confirm source, bypass/transfer, load surge, AC wiring and generator behavior from the exact manual.
What documents should the RFQ include?
Request exact datasheet/manual, nameplate, wiring, PV/battery settings, protection schedule, compliance evidence, BOM and warranty.
