What battery chemistry is inside? If it's lead acid, my brother it's not it o. Like I always say, those 12v4.5ah batteries in those fans are crap. Short run time and 3 months, maximum 6 months lifetime.

I have settled for DC powered QASA fan and diyed solar charged lithium battery pack for it. It runs 9 hrs max speed after full charge
.

What is the ah of the battery that goes 9 hrs

For your rechargeable fan

Replace the lead acid battery with lithium ion / lithium polymer battery. The battery protection circuit in most of the rechargeable fans are poorly design which in no time kill the battery. To get optimum performance from the rechargeable fan replace it with lithium battery


What about the charging algorithm of the factory CC in the fan which is tailored for lead acid chemistry (14.6v boost charge)? Except his lithium battery is LFP type with 14.6v full charge (3.6v per cell: 12.8v nominal 3.2v per cell - 4s config) which is the only condition in which he can get by, using any lithium config with BMS specs less than 14.6v (usually 12.6v for majority of 3s 18650s) may not be the best.

This is not absolute of course. If the lithium battery BMS has an integrated 12.6v CC-CV buck circuit, he can comfortably charge it directly with an 18v solar panel.

I looked the way of li-on batteries too but my fear Is this "catch fire, catch fire" issue everybody keeps talking about li-on batteries. I can't afford the ready made and will have to build one myself. Hence my increased fear. Supposing a member of my family made a mistake or something happens? I am hardly home.

There are laptop power bank case that you can easily pop in your lithium batteries and have them power the fan. The power bank has BMS and adequate overcharge and overdischarge protective circuits.

6pcs 2000mah 18650s in 3s2p config. Same config that most laptop batteries come in.

Oh...if so the Voc of most 250w panels is about 38v, thus 3 in series will exceed 100v, which is the max rating of your cc..some cc cant accept a lil above, some don't..so to play it safe, getting 2 more 250w panels and doing a 2s2p setup may be the best route

HERE IS THE LINK TO ANOTHER WEBINAR BY MORNINGSTAR CORP:
https://register.gotowebinar.com/register/2850930699874060034

Thanks man. The 150 watts I found is 18v.

How do I incorporate this to my existing setup of 24 v.

Do I connect in series or parallel or both?

Please can you help list the top five 2.5KVA inverter?

earthrealm:


ok, stilll a lil crude, as it simply groups batts into flooded, sealed etc...and doesnt state the corresponding voltage charge setpoints..

take quanta batts for example, its float is 13.5v, boost 13.8v, while Long Batt has float 13.8v, boost 14.6v, and they are both smf agm batts.
so hope you now understand, the shortcomings of the luminous inverter

good the owner 's primary charging source is solar, and not grid.
left for me luminous isnt in my top 5 chinco makes when am considering a serious 2.5kva and above inverter...unless its for off grid installation

earthrealm:


how soon are you getting the genpal?, ..am tempted to buy the GK series as well.
4.8kwh for a setup that goes into float by noon isnt bad...as most systems usually produce 40 to 50% of their capacity by noon. this implies you wud be hitting 3.5kwh to 4kwh by noon

GenPal secured will hopefully get through with installation this week but will only be able to provide some useful info next week. That said I checked my log today and was at 2.7kwh by 11am and the system did 5.2kwh on Friday, which is the highest have done so far. Will see how far it goes with at least 3hrs constant GenPal load from next week.

Cheers!

I LIKE THE GRAPHS, did it come with the inverter?..or another app?

@ house, anybbody running a batteryless inverter? in battreyless mode?

It didn't come with inverter, It's emoncms mobile app, it's reading data from an emoncms server that I have setup on my RaspberryPi to receive data the inverter via USB.

GenPal for 3hrs will be in the range of 1~1.5 kWhr or even less if your preset temperature is above 28°

This is potentially true but usually at a higher equipment price/harvest cost.

Welcome to flexmax family.

Thank you very much for your kind response. There is an improvement but I discovered that the battery bank is not holding anything again. Immediately the sun drops it goes off. I also noticed a battery within the bank that is given 4v but the rest are at 2v each. Can it be the caused of the problem? Another thing I discovered is the CHARGED display on the Status display but the bank was not actually charged. Thank you!
Re: Solar Energy, A Complement To FTA by enet1(m): 7:38pm On Dec 18, 2019
Good Day to everyone,

I have few questions to ask

(1) Is it all inverters that does automatic changeover when there is power outage? If not, how can I know the one that has automatic changeover?
(2) I have a load of 950 watts (14 energy saving bulbs, 5 celing fans, a TV, a laptop and other small loads), Is it advisable to go for 1.5KVA or 2.4 KVA inverter system ?
(3) is it all inverters that come with chargers for self charging?
(4) I have ordered for two new 100ah batteries, can i complement it with one used 200ah battery?
Re: Solar Energy, A Complement To FTA by solasola(m): 8:03pm On Dec 18, 2019
Evening my ogas. I need a little analysis of a system that can take load of about 2.5kva for at least 6hrs.

In my opinion. I am looking at a 24v/3.5kva inverter,4pcs of 200ah, tubular batteries, 6pcs of 250w/24v of pv, 80A pwm. Pls i need you guys input as per best models, and any tweak on the system to work well. The system will be grid tied. Fairly stable electricity.Earthrealm, niyiol..., kiekie.ojeysky,ceaser etal..

Thanks for the forensic analysis bro.

I'm planning to get at least another panel to augment what I have.

Between getting a 300 watts panel and getting 2 150 watts panel, which do u recommend.

I'm asking because of the amps I should expect in harvest
