Y&H Pure Sine Wave Inverter DC12V,AC230V Power Converter for Home Backup Power, RV, Truck,Off-Grid

Y&H inverter adopts the SPWM technology of MCU micro-processingcontrol, pure sine wave output and pure waveform. The unique dyna-mic current loop control technology ensures the reliable operationof the inverter. Strong load adaptability, including inductive loadcapacitive load, resistive load, mixed load. Strong overload andimpact resistance. With input overvoltage, undervoltage, overloadoverheating, output short circuit and other perfect protection functionsSinusoidal inverter adopts LCD liquid crystal display mode, the state isclear at a glance. Stable performance, safe and reliable, long service life
Note: Inductive appliances have peak requirements for startup: motors/motors/pumps and other appliances with high power at startup. The power of such appliances when starting is between 3-7 times the labeled power of the appliance. Only after the startup is slowly restored to the rated power. Different appliances have different starting power multipliers. For example, 1000 watts of water pumps, this 1000 is the rated power, it will instantly start up to three or four thousand watts, and then slowly drop back to 1000 watts of smooth operation.
Q1:If I bring the above appliances, what size is recommended?
The starting power of loads with motors should be tripled, for example, a 500W chainsaw will start at 1500W, so you need to buy a 2000W inverter.
①Air conditioner load
2000W can take 1.5 horse inverter and 1 horse fixed frequency, 3300W can take 2 horse inverter and 1 horse fixed frequency.
3000W can be used with 2 inverter 1.5 hp fixed frequency, 5000W can be used with 3 inverter 1 hp fixed frequency.
② welding machine: ask the customer how many welding rods, 2.5 or less discretionary recommendations.
3000 can take 2.5 welding rod
③ water pump, with a compressor, the minimum three times
④ fan 1500W, with a compressor, recommended 3000W
⑤ pumps, such as water pumps 500W, 2000W can bring
⑥ freezer with compressor, according to the double counting; ice cream machine 1000W within the recommended 3000w inverter
⑦ angle grinder, drill, no load with up, ordinary power
⑧ ordinary household appliances: kettle, induction cooker, electric frying pan, refrigerator. Rice cooker, etc.
⑨ chainsaw, coffee machine
