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

1.6–8 kW table members; 12/48 V routes

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.

Continue the system review

Prepare an evidence-based off-grid RFQ

Record real loads, battery and PV inputs before asking for a final configuration.

Battery and backup sizing guide

Off-grid inverter FAQ

Questions to close before quotation

The exact member and installation design remain decisive.

Which rating applies to this HB 2–10 kVA inverter charger?

Use the exact quoted model and its table row. The current family record is 1.6–8 kW table members; 12/48 V routes.

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.
