Regarding question number 1. I asked same question here, but no one answered. So i went on a quest to get answers from Youtube.

There is a simple calculation: Divide the size of your solar panels by the voltage of your system. So, of you have a 600watts panel system on a 12v battery bank setup, you should use a CC with a minimum rate of 50A (600watts/12v)

Folks here are volunteers so don't feel bad Bro, you could have flagged the question again, am sure you got response to other questions in the past.

Now to the question, what you have stated is just for CC capacity calculations not MPPT Vs pwm the reason for that is that MPPT is more efficient and once your hervest starts going above 20A it's much better you get an MPPT CC instead.

I need the input of the experts on an upgrade I am about embarking on .

I have a 1000watts,12 volts inverter on 3 units of 105ah batteries connected to 640watts( 160 watts* 4 ) felicity panels via a 60amp PWM Controller.

I intend adding more panels panels ( additional 640_watts) but the max PV power input of the CC is 720watts( of course replacing battery bank with 3 units of 180ah battery)

I am considering the following options

A. Run separate wire for a new 60 AMPS CC connected to the new panels

B.Buy a 100amps PWM Controller( found about 2 already on Ali express) with max PV WATTS capacity of 1300 watts and just change the charge controller.
This saves the cost of running separate wires

I just need the input of the gurus!!

Get another 60amps pwm cc and connect the 2 in parallel but you will also have to increase size of cable cos you are expecting more current at 12v.

Someone on this thread said prime delivers above name plate so I decided to give it a trial on my recent deployment and got 2x380w from @justcallmenuel. Today when the sun had a brief laughter I saw 0.84kw and it stayed for at least 2min, unfortunately I didn't take picture and no loging option at that site. My 280x9 sunfit was also slightly above name plate (power) when I checked my log today.

Certainly solar will be what more people will transition to with increase in utility cost/bills.

My fear is, solar may become more expensive. Government may try to make it unattractive so that the power companies would have a market.

Valto:
at this stage of your upgrade u shouldn't be using a pwm cc
i advise u trade off your 12V 1000w inverter
get a 24V inverter with at least 30A utility charger
buy a 60A mppt cc
buy premium 2pcs 200ah or 220ah battery
then u are good to go

Thank you for your response.Actually this set up is my back up system which is why I haven't bothered using MPPT CC.My main system is a 1.5kva 24v Luminous Zelios Inverter connected to 2 200ah Luminous SMF battery and 260w x 4 units of Felicity solar panel through a 60 amp PowMr MPPT charge controller. This powers my TV and lights mainly light .The 1000watts system ( actually actually a1.5kva 12v Icell X4 series inverter)powers my fridge,freezer and security light points when necessary, although I use it mainly with the freezer only occasionally except during long NEPA outage or when I just need to power some points it is connected to.

Yes, folks here have been very very helpful in providing answers to questions from their wealth of experience, and we sincerely appreciate.

Regarding the emboldened? When does your harvest begin to exceed 20A? Is it when panel size exceeds 300W (going back to my previous calculation of 300w/12v) for a 12v system or when you battery bank exceeds 220ah?

Kindly expatiate. Thanks

Bàbá, just do the bolded jéjé if you can afford another MPPT. Get it connected to the battery bank alongside your existing MPPT.

If you get PWM, cabling will be a challenge for you. You will need thick guage cables to run 100 amps current and you still get to lose efficiency with the use of PWM.

Black people tend to be innately wicked to 'emselves, aided by the whites who don't mind as long as they get something to gain at your expense. Blacks are ypically sado-masochistic. See that Nigerian lawyer that deliberately bungled Nigerian case against P&ID cos he was bribed to do so, costing the country billions of dollars.

There are great and wonderful black people and I'm one of 'em but the majority is just too terrible.

A while back in the UK, you would get discount (paid for by the government) on solar products if you decide to go green. They pay you half and loan you the remaining half which you pay back over sometime.

In Germany, the citizens have completely gone alternative that the grid power is lying redundant and unused. The German government is even appealing to the citizens to patronize grid power at very subsidized rate.

Olórun ñgbó, aswear, if this government tows that useless path of making alternative energy outta reach for Nigerians beyond the nonsense that they are currently doing, I will personally petition the Almighty and go on fasting spree that thunder should fire all those that are behind it.

What is so difficult in doing things that make life easy for us all especially when it is within our power? Is it by force to keep people in perpetual servitude? There's an adage that goes: If the diety would not be kind enough to benefit me, then it should be kind enough to leave me as I was.

Right there is such a possibility especially in naija....I guess folks should stock up as much as possible. Perhaps another reason why getting LFP for now will be better for longer term planning

The 20A is not a definite guage, generally If your Panel array is more than 500w I will advice you go MPPT it's just more efficient than pwm and you really want to utilize your hervest as your panel size increases.

If the Lumos you wrote about is similar to that MTN Lumos package then that's not an "inverter". It's more like a whole system. That is, battery + inverter + charge controller in one box, in a small form factor.

That being said, for the merciless power-hungry 230w laptop charger, you may get by with a 500 watts inverter if you are low on budget. You will also need to get batteries, AC battery charger and/or charge controller plus solar panels to complete the system.

Thank you for your detailed reply, I appreciate it.

Hi again, I've done a little research, and I think this is what I need:

A portable powerbank with pure sine wave AC output, and 250-300W continuous power output. Capacity should be above 200 Wh at the very least. 300Wh preferred. Basically well above 60,000 mAh

It should be able to be charged directly with NEPA light, but also be charged with a Solar Panel. Please suggest the minimum solar panel that can charge the aforementioned power bank in a reasonable time.

Basically I need something like the keepworkpower.com home system that can offer higher continuous power output.

Can anyone here get this?

Please guys,how can i stop my house from using PHED during the day even though there is power.It's now that the tariff has been increased by over 100% that they now give us light.I want to be using solar in day time and PHED at night.Can i put my changeover switch on neutral during the day to achieve this.I don't want my meter reading unless i want it to.

Your inverter should definitely have an input switch (charging switch). Switch it off and use your inverter.

For sale. Used eapro 500va and contec 1kva. Working perfectly.
500va -28k
1kva - 38k

If your change over switch is from phed then yes but that means there won't be utility to charge the battery neither will there be utility to power your household. What kindly of inverter are you using? There are inverters that can be configured to use solar power first before utility power. If you don't have those kind of inverters then you need timer switch to alternate between utility and inverter power sources. I think @valto advertised some

I use prag .The way our solar setup was done,we ran d connection of heavy items (AC, Pumping machine ,Laundry room and microwave) to only work with Nepa then all others was connected to work with solar.

Yes the AC sucks. Only cools the room on cold nights. During the day it struggles to keep the room at 27. My window non inverter AC does a better job
The batteries are 5 kwh. I have 4.3 kwh in PV. Thank you for watching and commenting

Hello, what's the brand of the inverter AC you are talking please? I'm in the market for an AC and I'm torn between Inverter and non-inverter AC, so I need to know what to avoid. Thanks
