Please i need help on a simple method of converting DC to AC
The desired AC output is to power a mini laboratory incubator
The desired AC output is to power a mini laboratory incubator
So what's your suggestions, please am open to ideasAveragesupernova said:You want to err on the side of caution. If 1200 is just enough to power it then you should go with a larger inverter. Generally a larger inverter will not draw any more than a small one with the same load. It's better to have a large inverter do the job with ease than to stress a small inverter.
Do you have the nameplate amperage or wattage of the incubator?Declet Uche said:So what's your suggestions, please am open to ideas
220V~240V ACruss_watters said:Do you have the nameplate amperage or wattage of the incubator?
Waoowh very detailed, thanks so muchCWatters said:Can you tell us more about the reliability of the power grid? I think this might not be cheap to do.
Inverters aren't always very efficient. If we assumed 75% efficiency then 750W would turn into 1000W drawn from the battery. At 12V that 1000W works out at 83Amps.
If you need it to power the incubator for the whole 24 hours the batteries will need a capacity of just under 24 * 83 = 2000AH approx. You might even need double these figures as lead acid cells don't like being deep discharged frequently. If you regularly deep discharge them they loose capacity and life time. I think that's going to be quite a substantial and expensive battery. For reference a typical car battery is around 100AH.
You also need to think about how you can recharge the battery. If the power grid is only available for part of the day the charge current needed could be very large. For example suppose the grid is available for 6 hours a day then to recharge a 2000AH 12V battery in that time would require 2000/6 = 333A. That's a substantial charger.
Thanks alot, it explains the history and ideology behind inverters, but no circuit of how to make one there sirdarth boozer said:

You are asking about stuff with the target voltage at the level of the grid AC. You should just forget any homemade stuff and buy the ready-to-use components.Declet Uche said:Thanks alot, it explains the history and ideology behind inverters, but no circuit of how to make one there sir
There are several ways to invert DC 12V to AC 220-240V. One option is to use a power inverter, which converts the DC power from a battery into AC power. Another option is to use a DC-DC converter, which steps up the voltage from 12V to the desired 220-240V. Additionally, some electronic devices such as laptops or smartphones may have built-in inverters that allow them to be charged with DC power sources.
Yes, a car battery can be used to power a power inverter or DC-DC converter to invert DC 12V to AC 220-240V. However, it is important to make sure the battery is fully charged and has enough capacity to power the desired devices.
The type of appliances that can be powered with an inverted DC 12V to AC 220-240V depends on the wattage and voltage rating of the inverter or converter. It is important to check the specifications of the device and make sure it is compatible with the power source.
Yes, it is important to follow safety precautions when using an inverter, such as making sure it is properly grounded and not overloaded with too many devices. It is also important to use the correct size and type of cables and fuses to prevent overheating and potential hazards.
It is not recommended to use an inverter to power an entire house or office, as it may not have enough capacity to handle the high wattage demands of multiple appliances. It is best to use an inverter for smaller devices and appliances or to invest in a larger, more powerful inverter for larger power needs.
