3000W/4000W Pure Sine Wave Inverter — DC 12V/24V to AC 110/220V (50/60Hz) Solar Off‑Grid Converter

Battery compatibility and voltage ranges: the 12V version must be paired only with a 12V battery (normal operating range: 9.5V to 15.5V). The 24V version must be paired only with a 24V battery (normal operating range: 19V to 30V). Battery type: do not use lithium batteries — connecting a lithium battery may damage the inverter. Use a lead‑acid battery. Safety warning: never connect the inverter directly to the household AC mains circuit. Power rating guidance: understand the difference between peak (surge) power and continuous (actual) power. The unit’s casing is labeled with the peak power; the continuous (actual) output power is equal to one half of that peak value. The appliance’s starting (surge) power must not exceed the inverter’s peak power. During extended operation, the appliance’s running power must not exceed the continuous power rating. Definition and example: peak power is the highest output required at motor or compressor start-up. For example, a refrigerator with a rated running power of 300W can demand a start (surge) power of up to 2500W. Purely resistive loads such as incandescent bulbs do not have a separate peak (surge) power requirement.
