Dolphin Pure Sinewave Inverter Wall Mounted 800VA, 500W, ME-WMPS-8000

Our review

This Dolphin unit is a wall-mounted pure sinewave inverter rated at 800VA with a 500W power output, designed to run on a 12V DC battery and accept mains input between 140 and 275Vac. The pure sinewave output matters if you plan to power equipment with motors, compressors or sensitive electronics, since it produces a smoother waveform than modified sinewave models. It suits a household or small office wanting a tidy wall-fixed backup setup rather than a portable box. Before buying, confirm your battery is 12V and sized for your intended load, and note the stated transfer time of under four minutes, which is slower than many automatic switchover units, so it may not keep computers running without a break. Compare against higher-capacity inverters if your load approaches 500W, and check whether your battery charging setup matches this unit. It is available on Sokonia.
