Based on your Listed appliances (2 fans, TV , 2 Laptops, 2 Consoles -minus Fridge and dispenser), The Ecoflow Delta Pro (3.6kwh) can power everything for about 20+ hours ( everything depends on usage) and if you fill like it you can adda an extra battery to expand capacity to (about 7.2kwh) and you can get about 2 days without solar charge. If you want to add solar s you will extend the usage for as long a s possible. While Ecoflow s are good i think they are a bit pricy and you can save money by using quality options like Jinko 555w which is more budget friendly. everything depends on usage to make purchases you can https://detopsyelectricalshop.com/ecoflow-nigeria/

Thank you for the . Decided to go for an inverter system instead

Does Deriy have packs with EVE or Catl cells or they only use Hithium cells?

They have packs with all of them.

Just depends on the battery size..

Good day gurus...

If I have two 590W s, 12v 3000W transformerless inverter, a 12v 100AH LiFePo4 battery and a 60A 12v/24v Felicity Charge controller.

1. Can I connect the two 590w in series to the 60A 12/24V mppt charge controller in order to charge a 12v lifepo4 battery.

2. Since my s are oversized, It is Felicity 60A charge controller. I intend connecting a total load of about 500W during the period of sunset (from 7am to 4pm daily) between the CC and 12 v 3000w transformerless inverter.

So Is it possible that while the charge controller delivers about 720w to the battery, the remaining power from the will be supplied to the load of about 500W.

Good morning bosses in the house. Please i need your input on this.
There is a boarding school that called me that they need an solar system that can power their water pump everyday.
They have 4 water Sumos of each 3Hp totalling 12Hp. Please i want to know the size of Battery bank, Solar s and inverter to use for this project.
Note:, they use water every morning before they go for classes, also evening time when school closes. On weekends, they use it mostly for washing of clothes and other hostels chores.

Hi sir, it's Kayla from Deriy in China, we have EVE (LF280K/ MB31), Hithium, Catl, Gotion, Svolt for you to choose from, add my WhatsApp+86 19068617017, you will get more information.

I'm sorry that all of our batteries in Nigeria are sold out, you will get the battery on the picture in June if you order now, those batteries have already on the way to Lagos.

Tricky. They can pump in the afternoon to handle the evening usage but the morning one has to be handled entirely by batteries.

Also sumos are tricky, since most draw a lot more than their rated output. For example, this 12HP is about 9kw on paper but in real life could be as much as 15kw.

What I'd tell you is to go there and get actual real life data on

- Power draw on each sumo
- How long it takes to pump full

You need a watt/clamp meter for the first one.

1. The charge controller max input voltage will determine if the s can be connected in series or parallel.

2. The 720w is the maximum power the charge controller can output for a 12v system, so if you connect a load of 500w to the inverter, the remaining 200w+ will be used by the battery for charging.

Thanks for ur response.

This is the spec of Felicity 60A CC.
Maximum Input Power: 12V-825W (Parallel). 24V-1650W (Series)
PV Array MPPT Voltage Range: 60-130V DC

The 590W PV parameters when connected in series:
Voc= 105.26v (52.63v * 2)
Vmp= 87.42V ( 43.71v* 2)
which is still within the pv array range of 60-130v.

It means if I connect the pv in parallel, I'll be limited to just 825W whereas my combination can produce 1180W(590w*2). That's about 355W wastage, meanwhile connecting pv in series will yield 24V-1650W.

can I conclude by saying the pv series connection is better for my setup since the mppt charge controller can still charge my 12v lifepo4 battery even though the pv are series connected.

I have this POWMR 60A (pics attached) charge controller and 3 pieces of Jinko 590W s with the following parameters.
My system is 24V.


Maximum Power Voltage(Vmp) 43.71V

Maximum Power Current(Imp) 13.5A

Open Circuit Voltage(Voc) 52.63V

Short Circuit Current(Isc) 14.13A

Is it okay to series this s with this controller?
If not, can you recommend a controller that can do this work and give room for possible future upgrade?

You have missed an important detail.

What voltage does your battery run? 12v 24v 36v 48v

Oh, 24V.
Thank you.

bkuranga:



Oh, 24V.
Thank you.

connect all the 3 s in series

bkuranga:

Thank you.

Series just 2 s as Max pv for 24v powmr is 105v.

Guys just a quick question pls. I’m still learning

I’ve observed that a lot of suggestions here tells people to series their s (even for a 12V system) which I know increases the voltage and keeps a constant current.

For example, someone suggested a series connection for 3 s likely to have a short circuit voltage of 48V and above for a 24V system. This is more like 144V (I.e 48V*3). Sorry, but is this voltage not too much for a 24V system?

Or Will the controller limit the input voltage of about 144V coming from the to the required charging voltage of 27V-28V for the system?

If yes, then what happens to the other voltage? Is it wasted? If 28V is what is being used for charging the voltage and the constant current in the system is 13Amps, it means that the power from a supposed of 1872Watts (I.e 144V * 13Amps) is actually 364Watts (I.e 28V * 13Amps).

Please someone should kindly educate me on this, it’s interesting to know. Thanks.
