sine wave inverter requirement sheet
A short field list so a sine wave inverter line, and neighbouring off-grid inverter lines, can be quoted on the same paper. This page is a specification worksheet, not a carbon or ESG statement.
Lines that belong on the sheet
A sine wave inverter request should name waveform as pure sine (or modified sine if that is actually wanted), continuous watts and surge with duration, DC input voltage, and AC output voltage with frequency. Do not paste an inverter/charger or a hybrid photovoltaic unit into the same row: those are different machines even when they share a rack. Mounting orientation, cooling method and listing (for example UL 1741 when that standard applies to the offered catalog number) are mandatory when the destination procedure requires them; otherwise they stay optional notes. The supplier must confirm back in writing the offered model, continuous and surge watts, DC bus, AC output, waveform, accessories in the carton, quantity, Incoterms or delivery basis, and the listing document for that model number if you asked for one.
Required
- Product name: sine wave inverter or the neighbouring off-grid form if that is the real line
- Continuous watts and surge watts with duration
- DC input voltage (V DC) and AC output voltage with frequency (Hz)
- Waveform stated as pure sine or modified sine
- Quantity and unit, destination and requested timing
- Installation environment if enclosure or cooling matters
Optional
- Budget, currency and per-unit or total basis
- Supplier preference: premium, mid, low cost or undecided
- Listing document for the exact model (UL 1741 or other named standard)
- Remote, extra GFCI outlets, hardwire kit, mounting brackets
- Sample of one configuration before the bulk quantity
Optional fields only narrow the search. A factory can still quote if budget and preference are blank. Do not pre-fill the requirement box with a helper summary; write the duty in your own words. After the sheet is filled, send it from the inquiry form, keep a copy against catalog options, and use the six-line article if DC bus versus watt figure is still unclear.
