Solar induction cookers are the best way to do solar cooking. You can do solar cooking at any time of the day in the comfort of you kitchen with an induction cooker. Here I am using solar power to cook a meal using an induction cooker. Cooking uses a lot of energy. So when you are using an off grid solar power system to cook your meals you have to use a very efficient cooker so that you dont waste that precious solar energy. Solar induction stoves are highly efficient. They use magnetic waves to induce heat in the pan. That way the loss as heat to the environment is less than a normal hot plate. The pan you are using should also be induction cooker compatible. If a magnet will stick to the pot base then it is induction stove compatible.
The other important factor is the battery. You need a large battery to store the amount of energy you are going to use for solar cooking. This is important especially at night when there is no sunlight for solar cooking. In this video Im showing how I combine 32650 LiFePO4 batteries and lead acid batteries to make a hybrid battery. By combining lithium and lead acid batteries together I can extend the cycle life of both batteries. The battery voltages are such that I am able to use the lithium iron phosphate battery for most of my daily cycling and use power from the deep cycle lead acid battery once the lithium battery reaches less than 20%.

Thanks!... Remember cooking uses a lot of energy so if you are planing on using solar for cooking go for the biggest system you can afford. Also consider 24v systems over 12v systems as the power draw through the wires will be high!

I loved the way you could set the watt loads on the induction cooker, that's great when you only have so much power! I also really loved the idea of using the pressure cooker for really efficient cooking! Would love it if you could try the pressure cooker at lower wattage's like 400 or 500 watts. I think the pressure cooker should still work but just take a little longer to cook? Maybe even try it at 200 watts. I think once the pressure has built up the pressure cooker will carry on cooking after you turn off the induction hob too! It would be great to find the combination of lowest watts and length of time in the pressure cooker after turning it off to cook food.

@diysustainableliving2774 Жыл бұрын

Yes... it all depends on what you want to cook and the quantity you are making. If you are using a little bit of water you will get steam fast. If you are using a lot of water you may not come to a boil fast but you may be able to do slow cooking at a lower temperature. But if you want to do serious cooking I would suggest you go with a 24v system, big batteries and a larger solar panel array to be sure you have enough power to cook day and night.

@batterynerd8779 Жыл бұрын

Very nice. Iam also thinking about combining both chemistries. But the problem is, that the lfp batteries will constantly float charge the lead acid, which leads to a lot of electrolysis, which increases water loss in the lead acid and total energy loss in the system

@diysustainableliving2774 Жыл бұрын

Electrolysis becomes an issue once the voltage goes above 14.4V. But with the lithium iron phosphate wou wouldent want to go higher than 14.4v and when not charging the setup voltage drops to13.3V in the fully charged state. At this voltage the lead acid battery takes a negligible ammount of current!

@diysustainableliving2774 2 жыл бұрын

Yes.. it depends on where you live (Bright and sunny or cloudy), how much the panel produces in a given day and how much cooking you are planning to do. 200w panel should produce around 1kwh on a good sunny day. That should be more than enough to cook 2 small meals per day. But it is always best to get more solar panels since cooking is energy intensive. You will need all the power you can get.

Interesting setup. The readout you see on induction display are thermal watts. Electrical watts are much lower. Usually a third.

@diysustainableliving2774 Жыл бұрын

I dont think so because in this setup my inverter can handle 1300w continuosly. And here I cant go above 1200w on the induction cooker as the system goes into over load. So I think the power displayed on the induction cooker is the same as the power consumed. I cant be a third of that reading.

@viviancrompton1920 Жыл бұрын

Good job. Only improvement I can suggest is to try different cooking speeds to find optimal efficiency. Both cooking an egg and pressure cooking could be done either more slowly or more quickly, and there will be energy losses that vary accordingly - from inverter not operating at it's optimal point, inverters in the induction stove not operating at their optimal points, constant heat loss to the environment meaning faster cooking is possibly more energy efficient than slow cooking, and others. If you use a standardised test setup for your pressure cooker - such as timing how long it takes it to get to pressure, you can then use that to determine the optimal energy use profile for more efficient cooking. For example you might be better off running the pressure cooker at the stove's max power (1.5kW?) until it gets to steam and then reducing the power level to 500W to maintain pressure. Likewise for cooking an egg you probably only need to get the pan hot quickly, then can turn the pan down or even just use latent heat in the pan to finish cooking it. For example, Your pressure cooker might take 6 minutes to get to steam at 1000W, (i.e. 100kWh energy use) but only 3 minutes to get to steam at 1500W setting (ie. 75 kwh energy use) because it didn't have as much time to lose heat to the environment, or the inverter and stove's electronics work more efficiently at that level. if it tool 5 minutes to get to steam at 1500W then obviously that would not be better, (ie. 125kWh). Do that for various settings and cooking styles (eg. frying vs pressure cooking etc) and you should be able to plot the results and get an energy efficiency profile for various temperature settings per cooking style. It would also be interesting to know if using say, a small 1000w microwave to cook the chickpeas would be more efficient than using the pressure cooker. I think you would have to pre-soak the chickpeas for best results. I'd also use butter instead of oil for cooking the egg and mabey add a little salt and pepper, but that's just a cooking preference :)

@diysustainableliving2774 Жыл бұрын

You are right... Ideally thats how the induction cooker should be handled. First to heat up the pan at a higher power level and come down to a lower power level for cooking. As for the chick peas :) yes pre soaking would have improved results but this video was about proof of concept. I wanted to proove that with my solar setup I can cook a small meal. And not presoaking helps to reinforce the audiovisuals in this video. This is the most comfortable and conveniant way to cook using solar power. You dont have to stay in the hot sun all day and you can even use the battery power to cook at night as well.

And for people who want to utilize solar power every watt hour of power saving is important.

@diysustainableliving2774 Okay sir, thankyou so much....could you please explain sizing the solar panels and the batteries for the system according to a load about 1200W

@diysustainableliving2774 7 ай бұрын

Lets say you live near the equator on a nice sunny day. The maximum power you will get is going to be around noon. So the calculations goes as 3hrs before and 3 hrs after 12 noon. So lets say you have a 400w solar panel and you are using an MPPT charge controller to get 100% efficiency. The maximum power you will get on that day will be 400 × 6=2400whr or 2.4kwh. So it will be enough to run your 1200w load for approximately 2hrs. For the battery it depends on what battery chemistry you use. If you want to use it for an induction cooker I would recommend LiFePO4 chemistry as it is a relatively stable cell and quite safe for household use and has a depth of discharge of 80% for around 3000 cycles. That is almost 10 years of daily charging and discharging to 80% capacity. So for 2.4kwh you will need 2.4÷0.8= at least 3kwh of battery storage. These are just examples. These will vary depending on the time you need the cooker whether day or night and the size of your solar panels. If you have 1200w of panels and are cooking only during the day time you can use a much smaller battery and use the solar power directly for the appliance.

Sir, I've a doubt. How many solar panels (1 solar panel having 320W of power)would be needed If I have to use an induction cooktop of 1000W power and there're 2batteries available each one having 12V and 40A. Here the induction cooktop is functioning from the power of batteries only not directly from the solar

@diysustainableliving2774 7 ай бұрын

So for an induction cooker to work for 1 hour you will need 1kwh. I presume the batteries you are talking about are lead acid. In that case you cannot go below 50% DoD. That means for 2 batteries at 50% you have 12 × 40 =480wh. That is a max of 0.48kwh. So as long as the batteries can deliver you have roughly 30min of cook time with the batteries alone. Id recommend a larger battery setup or Lithium iron batteries if you plan to use the induction cooker at nights. But if you plan to use it during the day time only you can add your solar panels to give additional power. Basically if you have 3 × 320w panels with a good MPPT charge controller you can cook using direct solar power. Since you have 2 12v batteries id recommend you make your system a 24v system as the panel voltages will also be higher and you will be using less amps for the same power which dramatically reduces stress on the system and can reduce power losses. Remember to factor in power losses as well for all steps as nothing is 100% efficient!

@@diysustainableliving2774 Thankyou so much sir! Sir if we are charging the battery from solar and simultaneously using it for cooking, will it reduce battery life?

@diysustainableliving2774 7 ай бұрын

No it should actually improve it as the majority of the power during the day will be comming from the panels and not from the batteries. So essentially the batteries will be cycled less and thus should increase its life span.

My system currently has 250w of solar panel. As you can see in the video my battery also gets significantly depleted when the induction cooker is running. That is because the induction cooker needs 1000w, around 200w comes from the panel and the balance 800w comes from the batteries!
