Good day house,
Please I need advice.
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.

Hi all
i have asked this question in another thread but i felt i should bring it up hear for a quicker response

Would you advice i buy a normal 3kva inverter and buy a charge controller separately or getting the hybrid inverter of the same spec?
PS the hybrid standalone inverter seems to be cheaper than the normal inverter + charge controller cost wise. Any reason why?

At US$56,000.00 (N20.5M) for 20kwh, I would rather stay with LTO

Barezzi:
Confirm Setting 11: "Maximum utility charging current" is set appropriately.
Confirm Setting 16: "Charger source priority" is set to CSO or SNU.

I'm fully off-grid now, but i remember adjusting those settings whenever i wanted to charge from the grid.

Edit: i see Niyi already addressed you...In addition, don't change Setting 01 to UTI. Doing so, your panels will never charge your batteries unless the grid fails. Set it to SBU or SOL.

The shading i experience at 3pm every day is killing my output. Imagine a maximum of 906W from a 6-panel 1800W array. Abeg who can supply and install this for 6 300W panels:

earthrealm:
aha, superb, this is the kind of review i have been looking for.
ook, 1 of the principal loads in the setup is a 2300w steam pressing iron..........n the closet substitue is a 1700w steam iron...any1 who knows or have a low power full steam iron should holla...guess that leaves me with prag or highpower inverter

Hello Pranil
I will appreciate if you can assist with details on where you bought the LG dual cool.
It is not readily available.

Many thanks

foonshur:
I use the "inverter v/gencool" aircon by LG

Chichilas:
Hello pranil,

I am interested in the power regulator/controller. Can you provide me a link to the product so I can order??

Thank you in advance

Hi. I am coming home shortly to commence the finishing of a flat roof duplex, part of which is a Axion concrete roof terrace. Abdulwastecx provided the overall design and served as consultant for the frame phase. He may, subject to negotiation, handle the overall finishing work. One of the critical needs is to assure reasonable electricity supply by including properly designed solar solutions as part of a harmonized electrical plan finishing. Accordingly, I have for a while followed this thread and GeorgeD1, you, and many other trailblazers. I have also read as extensively as a layman could about the rapidly evolving trends like Lithium ion batteries and AC coupling (with zero grid feedback) vs DC coupling as part of ESS. I have decided on using the roof top solar water heater, alike GeorgeD1, as guided by responses to my earlier inquiries here.

I have read over your BYD storage implementation and your many other “thinking out of the box” solutions. On your trail, I have gotten to learn more about BYD, Tesla, etc High vs Low volatage lithium batteries and the supporting respective inverters. Subject to our Nigerian contextual limitations, I will like to:
1. Build an Ac Coupled system,
2. Use Fronius solar inverter for PV DC to AC string inversion
3. Use Fronius Smart meter as part of the monitoring and bridge to the grid
4. Use Victron Multi or Quattro, SMS Sunny Storage (higher capacity models due shortly) for the battery charger/ inverter
5. Use the BYD High Voltage Lithium box
6. Until Nigeria, like Ghana recently did, approves grid feedback, implement an zero feedback island that ensures uninterrupted PV tapping, even if I have to include a parallel CC feed to battery inverter, as per the combined AC/DC Coupling permissible for Victron name ESS.

Towards, firming my expectations before engaging one of our reputable designers/installers, I would greatly appreciate an opportunity to discuss the above and other wants vs needs and methods issues with you.
Your can reach me on WhatsApp: 678-764-4535

Thanks.

Pranil can give more details on your air conditioning system.

Kudos to your set-up! How do you run your 1500w water heater 24hrs ? What's your battery bank capacity and solar capacity ? Remember you stated you had no space on your roof for the non pressurized solar water heater but if you can work on your piping, you can use a pressurized solar system..
Your pics states 1500w for just a 10L ariston/sweethome which can't serve a family of 4-6 .. Why we emphasized more on central water heater are ;

- centralized solar heating water system with reservoirs ranging from 50L-300L
-Ability to retain HOT water for 72hrs
-Central heating element of 1500w for rainy days or emergency
-Unique concept for those who have more than 1 bathroom etc...

Its an integral step/approach when building but can always be improvised like George D initiative .. I applaud your efforts but running an Ariston 1500w or a thermostatic 1500w air-condition for 24hrs on your main battery bank will leave you in the DARK someday and also reduce your expected battery DOD and lifespan...

Barezzi:
Does it also capture data from Midnite Classics?

babaegun:
@dapsyra

If you can extract the api´s from the midnight classic website, then it is a piece of cake cause thats exactly how i upload to pvoutput.org. I pick the api´s from emoncms and upload to pvoutput.org

You´ll need a raspberry pi, install php on it, internet connection, schedule it on crontab and voila, you are up an running with your live data.

dapsyra:
I am still searching for a way to automate the process.

The classic 150 automatically upload the data to MyMidnite website every five minutes, I then download the CSV and upload to pvoutput website after sunset.

Let me know if you find a way around.

bigrovar:
So the newer Ipowerplus are same as newer models coming from. Axpert / mpp solar?

And damn.. How do this people do it. I would keep my fingers crossed and see how well the new models perform over a period. Chinese Taiwanese are known for cutting corners which might end up affecting durability.

bigrovar:
It was me. Thanks for the insight. We got the inverters as a donation from a government agency sometimes in 2016. The error made me lose confidence in the durability of the ipower / axpert inverters.

olagunju2000:


my panel spec is
1) 15 pcs 300W mono solar panel (3 in series and 5 parallel)
2) Panel Spec:- VOC = 44.3, Isc = 8.93A, Vmp = 36V, Imp = 8.33A.

My Vmp is 36V per panel. Can I still use the Morning star 60A?
you can still use 2 units of 45amp morning star mmppt cc, cost $480 on amazon, and can handle 2400w @48v, so in real life you can split ur panels into 2....a not so ideal config, but u can scrap by if you wanna save cost of buying 60amp MS

nasonaso:
Pix of inverter

Is this connection suppose to be?

Using a meter to test. Voltage can be read at both the input and the output, is that right?

NiyiOmoIyunade:
As far as I know Outback is right up there in thesame class of premium controllers as MorningStar, Midnite, Magnum e.t.c. I don't recall anything negative at all about the Outback brand.

In fact Midnite Solar is a breakout from Outback and was founded by the same guys that worked on the Outback if I recall correctly

@Saipro, Pranil please help provide perspective - I think you guys have done the most research on the technicals for all these charge controllers.

Thanks for the links as usual... The first option is the most suitable for this application...But the limitation is that it can be easily bypassed (I guess)
