SWI — sine wave inverter 12/24 V, 250–3000 W
Country: Netherlands · Model: SWI
The SWI line covers 250–3,000 W continuous and runs from 12 or 24 V batteries. Output is 230 V ±3%, 50/60 Hz pure sine wave with THD < 3%, which switch-mode power supplies, motors and sensitive electronics accept without trouble. These inverters go into service vehicles, RVs, marine vessels, telecom sites and solar power systems.

Description
The inverter turns battery DC into AC with a grid-like waveform. Input on the 12 V models accepts 10–16.5 V, which spans a battery from deeply discharged to on charge. Peak power of 2× rated lasts < 1 s, enough for the inrush of power supplies and lamps, while a long compressor start has to fit within the continuous rating. Peak efficiency across the series is > 86–88%. Loads plug into a Schuko outlet or wire to terminals, and the terminal version goes into the distribution panel of an RV or boat. The smallest SWI 250 adds a 5 V, 2.1 A USB port for a phone or tablet.
How to choose
Pick the rating by the sum of loads running at the same time, and check the starting current separately. If a motor draws more than twice the rating for longer than 1 s at start, look at the PS series with up to 6,500 W for 3 s, which also has a 48 V input. When the inverter sits in a compartment next to the battery but is operated from the cab, the PSI with a remote panel on a 5 m cable is handier. If you also need charging from shore power, the PSC inverter/charger covers 1,300–2,800 W.

FAQ
What input voltage range does the 12 V SWI accept?
The 12 V models run on 10–16.5 V.
What output waveform does the SWI produce?
A pure sine wave at 230 V ±3%, 50/60 Hz with THD < 3%.
What surge load can the SWI handle?
Up to 2× rated power for < 1 s.
How do I wire an SWI into an RV distribution panel?
Use the terminal version instead of the Schuko outlet and run the 230 V output into the panel. Pick a rating within 250–3,000 W to match the panel load.
How efficient are SWI inverters?
Peak efficiency is > 86–88% depending on the model.
