In general the charge controllers embedded in the low budget (think 300k and below) hybrid inverters are not as efficient and effective as dedicated charge controllers. You will usually get more juice from your PV panels with a quality dedicated charge controller.

If you are budget constrained then you can do a hybrid inverter for starters and later upgrade to a dedicated charge controller when you have more funds. This way you also get some redundancy in case any part of your system collapses

I see you mentioned Mercury? You may be better off with the Axpert (Zinox and Gennex) ecosystem of which you can also get plenty of free support on this forum.

If hard pressed post the stats of both Mercury and Axpert options you are considerind and the house will respond with advice and hands on experience.

Hello sorry for late reply on the inverter thread .. Makavele , Mank , Pranil etc already gave you solid points ... I won't totally go against hybrid systems but mind you, its not as rugged as standalone pure sinewave inverter specs . I have a client who had a 5kva 48v hybrid"name withheld" , it went into flames in less than 2 months ... I also got a call from an Abuja based client today about his newly purchased Ipower hybrid that just blew up and company is busy with normal long drama on warranty . They stated after this repair , if it blows up again within same warranty year , warranty won't cover repairs .. Please feel free to contact me on whatever type you settle for , as regards to discounted prices and 1 year warranty .. Cheer's!

Yes they are LiFePo4 batteries sir.

That was lots of information you got for me there. thank you.

I am only trying to get a minimal setup for a student(My wife) in school. I have a relatively normal Solar setup with Flooded battery in my home. Though I have always been charging the LiFePo4 batteries with Nepa light.

Because of Budget, kindly help me out of this situation/
Can the MorningStar and Xantrex be PWM type CC?
Can I still regulate the FIX charging Volt and Current if it is PWM?
And lastly Would a 120W solar panel be optimum for just 1 battery.

Thank you once again. I am grateful.

mukhcech:
Good day my people... Viva FTA. Guys this is my battery and the charger information.... Pls can I get a minimal solar setup to charge this.... Our transformer don blow. Please help me mention the gurus in the house. Thanks.

My Batteries are 40ah...The real problem is getting a CC that can give the same output as the Charger. Thank you

Quanta Charging rate 25 %

I came across quanta manual which claims max charging rate for 200 Ah quanta AGM is 25 %. If I am reading right it means the 200 AH Qantas can be charged at 50 amps without any issues

Are my observations correct or I am reading it wrong.

Normally I have set the charges at 10 % or max 13 %

anybody has experience using such high currents 9 Life, overheating)

if the values are right then 8 Quanta can be coupled with Ipower/gennex to take advantage of their 140 amps max charge ratings even if the nepa is svailable 4 hours a day

pranil,
actually some high quality agm batteries can be charged at 50c or 50% capacity without
any issues at all. that is one big advantage of agm over gel or flooded and it's why savvy peeps
like us gravitate towards them.

Hello Sir , I am not surprised as I have seen same boldly inscribed on LONG 200a agm batteries .. Max charge current 60 amps and 30 amps for 100a batteries ! Cheer's

earthrealm:


so is this long battery agm too?. wondering wch battery setting to ue on mustpower inverter
1. agm1
2. agm 2
3. sealed lead acid battery

This is totally normal for AGM most can do between 30 to 40% of C20 when charging. ...

Hi everyone,
We are planning a 5KW solar panel build...

Please now, it's like I'm a ghost here. No one wants to even put in a word for me. I need to just get some advice please. Help a brother out

Good day house,
Please I need advice.
I have been using Inverters for close to 9 years and I have decided to add solar panels to my connection so I can minimize the cost of running generators to charge my batteries when Electricity is out. Although where I stay in Port Harcourt has a relative 14-18hrs light a day. Thou sometimes they get crazy and take the light for a whole week (Naija).

I have 12Nr 300watts solar panels which I have mounted on an independent mount so as to use it also as a car stand.
My Inverter is an Exulted 3.5Kva 48v system. (4nr 200Amps Batteries)
Issues:
Duh I have knowledge about Solar systems and prefer to DIY however I got an installer to help me look throu however we tend not to agree on the following
1. He says it’s better to connect 3panels in series 3 x 38.8v = 116.4v (using the Voc) and total amp of the 4 strings 4x10.21 = 40.84A (using Isc) since I will be using an MPPT
While I prefer 2panels in series 2 x 38.8v = 77.6v (using the Voc) and total amp of the 6 strings 6 x 10.21 = 61.26A since it’s a 48v system.
2. I prefer using a combiner box to connect all the strings before sending in to the Charge Controller
My installer prefers we just connect them using MC4 connectors and wires say combiner box is a waste of money.
3. The distance to the from the panel array to the charge controller is 45meters (148 feet), I prefer using 10mm flex, my installer prefers a 6mm flex.


I also wish to change my inverter to because my current inverter has a charging current of 11.4A and I will prefer an inverter with a higher charging Amp eg Mustpower or Felicity (any positive reviews on this product).

I intend to buy a Fangpusun 80A CC MPPT (is this a good product) coz I need a good CC with Digital meters I can use to study my output and possibly connect to the internet.

Thank you.

Blackbaron,
Hello, its not like if nobody wants to help.. Most issues has been tackled repeatedly if only you devoted time to go through the pages ... Most will assume you have an idea or a pro installer you are working with with as batteries you listed aint really popular in the Nigerian market and also trying to procure low watt panels.
As for me, your set up looks industrial with battery specs stated . The higher the watts of a panel , the better for you. I will go for Canadian solar 340m - 330wp , or higher wattage equivalent in either Yingli, Yachi, foresolar etc . we have high end inverters and charge controllers you can use ranging from magnum, Victron , shneider , Pt100 , connext , variotrack etc depending on the company or installer coupling your system .. Cheer's

BlackBaron:

Ok , sorry bro.
I have read up but I'd lie to say I have enough technical information to tackle such a project like this. While I know the basic components needed, I don't know enough about the correct inverters, charge controllers and whatnot to use for such a large scale model. Also with the items solar panels - batteries, etc Just that at the moment, it is going to be between a residential /diagnostics business hence we are a bit baffed on the level of sophistication this might need.

I have also seen some advice for/against 'Victron' (if not conclusive) amongst other things.

P.S Chuckdee, I dropped an email to you.
