150W DC 12V to AC 220V Inverter Board, Compact Converter Module for Car or Solar DIY Power

150W DC 12V to AC Inverter Board Convert a 12 V DC source to selectable AC outputs for powering small electronic devices and lowpower appliances. Designed as a compact inverter board with frequency square wave output and simple hookup for vehicle, marine, or offgrid applications. Key features Rated power: 150 W continuous. Input: DC 12 V. Selectable AC outputs: 0 V, 110 V, 172 V, 200 V, 220 V. Output waveform: frequency square wave. Output frequency: approximately 20 kHz. Quiescent current: about 0.05 A. Protection: none. No internal overload, short circuit, or reverse polarity protection. Why this product helps Allows running common lowpower devices from a 12 V DC battery source when AC mains are not available. Compact inverter board form lets you integrate it into DIY power systems and mobile power setups. Low idle current helps preserve battery when the inverter is on but under light or no load. Important safety and usage notes This inverter produces a frequency square wave AC output. It is not suitable for inductive loads such as motors, fans, coils, or transformers. For lowload electronic devices like LED lights, mobile phone chargers, and DVD set boxes, choose a lower AC output setting such as 172 V or 110 V for better compatibility. For prolonged load operation of 100 W or higher, install a large heatsink to ensure adequate cooling. Do not connect the input power in reverse. Observe correct polarity at all times. Use power supply and wiring rated for the required current to avoid overheating or damage. Do not overload or short circuit the inverter. There are no builtin protections. Measured noload voltages on a frequency meter may read slightly higher than nominal. Output wiring voltages (as measured) V0 to V2 = 110 V V0 to V3 = 175 V V0 to V4 = 200 V V0 to V5 = 220 V V5 to V4 = 20 V V5 to V3 = 45 V V5 to V2 = 110 V V4 to V3 = 28 V V4 to V2 = 90 V V3 to V2 = 62 V Installation tips Mount the board on a stable surface and attach a substantial heatsink if you expect extended runs near the rated power. Use appropriately sized cables and secure connections for both input and output lines. Verify output setting before connecting sensitive equipment. Provide ventilation and avoid enclosing the board in tight, unventilated spaces. Typical applications Powering LED lighting, phone and tablet chargers, and TV set boxes from a vehicle or battery system. Small electronics during roadside repairs, camping, and RV or marine use where AC mains are not available. DIY offgrid or backup power setups for lowpower appliances that accept square wave AC.
