olopan:
I'd like to commend Valto for his thoughtful ideas in his business, the battery box done for a 280Ah used for a member here was quite rugged and robust in it's structure.

No rickety sounds, all joint very solid and no gap for large particles of dust to enter.

It even held up to 60+ kg body weight and it withstood such heavy weights of the battery, all i can say is well done to him. This is my review of his build, and the circult breaker used was sized appropriately.

Guys check out this twitter post on rooftop types to avoid when planning to install Solar on your building rooftops.

Nice installation you have there with a well built support too, you can get the panels to generate more by up to 5% if the ground below is more reflective by flooring or back filling with white sand i.e. if the above has not been done.

Justice629:
Apologies accepted and below is the array mount.
Bright cloudy days are when bifacial truly excels not dark cloudy ones.

They have office or warehouse around testing ground ...or Jericho side.

I can't remember right now.

You can use Google with info I mentioned above

yemi2plus:
Please I need recommendation on reliable Luminous Battery sellers, preferably in Ibadan.

Thank you!

Pardon me, but the pictures you posted was my reference, which looks like they were placed on a roof, anyway my sincerest apologies.

Justice629:
Am amazed by how you reached the conclusion that my array is roof mounted :, it has always been ground mounted.

Assuming they are new, you wasted their potential.

Bificial panels are not meant to be installed like a regular panel as they use the albedo of the surrounding to generate more power (i.e. reflection of light to the back of the panel), thereby generating more power.

If you wish to really do the work. Your roof top is definitely not the 1st choice, secondly if that's your only space then installing them conventionally too isn't your preferred installation methods.

Wish you all the best.

Justice629:
Original tier 1 JASolar bifacial panels installed with similar results as my old questionable panel grade in this dark cloudy days.

It's for a training, I will discuss with them

cluewebhost:
Working perfectly.
30k
It was initially 60pcs, I've installed/sold most and have 4 surplus.

How much and is it still working?

cluewebhost:
175w but in Port Harcourt

Good evening! Please who has a 50W - 100W Used solar panel for sale.

Please kindly let me know and your price too.

Adding a Charge controller is fine, you will simply need to disable Grid charging so that the inverter will not overcharge your battery.

conyema12:
I have this one in mind. What if i add a charge controller so it can manage the charging for me

If you are the type that cared for your battery health before now (i.e. not letting your inverter battery to due to even beep before turning it off) , then you will need 24V 100Ah Battery has replacement.

But if you always allow your Battery to shut down when using your inverter better go for 24V 200Ah

Also you will need to change your inverter to one you can edit the parameters, preferably an Hybrid inverter.

conyema12:
Good evening great engineers. I would like to replace my weak luminous batteries with a Lithium battery. I currently have 1.5kva inverter without solar and two 200ah batteries .

What capacity of lithium battery should I go for? Thanks for your assistance

These past few pages has been overflowing with information, una dey do well.

https://twitter.com/oloyeadeniran/status/1685726015174156288?s=20

Check out this Twitter post that can help you make a better decision on your choice of Battery

This is always factored and dependent on weather conditions, but lowest I have seen is 105W from a 2,280Wp

BTW I replied your Mail, i don't know if you noticed that.

brightk:
jinko users in the house.. what is the worst energy generation you have gotten from ur pv array on clooudy days

You know 80% of Inverter user today do not put off their inverters and the scenarios described earlier are for cases of Inverter being turned off.

Also, the idle current is something that i will dispute but then i have inverter within reach to test with.

If you are an installer, nothing beats being able to diagnose and troubleshoot a problem remotely.

brightk:
Am in search of a good 2.5/3/3.5kva 24v inverter.

I wanted to go with the growatt system , am ok the datasheets i saw but the previous statements here abt the mppt side switch on and off just discouraged me.

I would appreciate your response

Please give the house your setup loadout when you are through.

FEGEITOK:
Currently doing a dry run.

How far does my battery discharge overnight?

Given that I have now disabled PHCN charging.

Can my solar panels recharge the batteries to float? If yes, in how many hours?

I am planning to transition the majority of my load (except AC, microwave, iron) to my alternative power supply by July 31, 2023.

the controller will control its output and it will not be damaged

Bgee77:
What happens if solar panels watts exceed the MPPT charge controller, where voltage and current are okay?

This hard to determine, you need to be creative with your load and use that to determine what your energy usage is, then the next step is possible.

you can play around with the calculator on my bio.

dbshaywhy:
Hi good evening professionals...
I will be installing tie grid solar power systems in new 3 bedroom buid... No air condition, no heater, no microwave... Just the regular appliance with 0.5 hp whale submersible pump.
Am currently on 12v system with tubular battery but will ignoring all that with new total systems...
I will love recommendations on what capacity of panels(jinko) , battery(lithium battery) and inverter (brand recommendations required) to work with.

I will so and attach to original post, i do appreciate the heads up.

FEGEITOK:
Sorry brother, this is why I upgraded to posting links in picture format as attachments. You should too.

The process of summoning the gods to undo the mistakes of the bot is too strenuous.

Thanks

Good day everyone,

I want to share with you the updated version of our offgrid energy calculator

"It is a DIY Off-grid Energy calculator which you can use to determine your energy requirements, solar panel size, Inverter size and Battery size too".

This is the Version 2.0, which is built based on feedback from previous release and it is improved with more additional appliances.

I will like to recommend it to those just starting there Solar journey and pro users alike to use it.

Attached in my bio is the link to the website where you can make use of the web application and also a short video showing how to use it in follow up thread.

Antibot keeps banning me with the links attached.

I will strictly advice that you follow the manufacturers guideline to prevent a issue down the line, if this is your personal setup by all means experiment.

A recent setup of 3 Growatts ES series inverters, the HUB was planned but not used because we used a comm/BMS cable from only one from the inverters and all the battery info was sent to all inverters.

All behave just fine with no problem.

jonescosmos:
Hello house, i need this Growatt CAN/RS486 Hub. The Growatt RS485 Hub with 8 ports is a device used to connect 1 battery bank and up to 7 Growatt inverters or charge controllers.
I don't if it's going to work with Deye, but I am willing to try it out.
This is because I discovered that only the Master inverter in a Deye Parallel Setup is able to read Battery Information (those who have Deye Inverters in Parallel should confirm this).
And this in turns reduces the solar energy harnessing power of the Slave inverters. So the solution to this is to make a splitted kind of Parallel communication where both or more inverters get their battery information individually.

It works this way

If your total Imp is =/< 32A the breaker will not trip, if you have did your calculations and see that you go over 32A from Imp then you can shell out the extra funds to buy a new breaker.

If not, continue to use it, since breaker are only meant to prevent overload of a circuit and not limit the current passing through them.

osayuwamwen:
Pls guys does using a 32amp DC breaker from solar panel to controller and from controller to battery limit the amps to not more than 32amps? even wen d controller support 60amps changing and the panel can generate more current?

I believe that zeestone sells something of that nature, it is a DIN rail mounted device that allows you to set the max. wattage to be drawn also current to be drawn. Maybe sintolord might be of help here

isangjohnson:
I'm planning to give my cousin 100w power max. I need to install something like current limiter that will stop them from consuming above the given watts.
Please, what device will handle this work perfectly for me?
Something that will trip off at my end if they attempt to plug appliances above 100w.
His house is opposite mine and they have been disturbing us with phone charging too much.
100w would be enough for phone charging and perhaps 3w bulbs 3-4pcs for night and 1 energy efficient fan.

Quite a keen sight to spot these inconsistency, i have not experience these before, but then it is worth a trial to test these conditions out in the real world and i will cirle back with a feedback.

viperVIP:
DON'T BUY GROWATT SPF 5000 ES WITHOUT READING THIS.

PS:: I am writing this not to defame the brand, but to read from others on their experience or maybe they just never find out.

I discovered growatt inverter on youtube channel of David Poz and further research on it led me to nairaland where I read from Olopan and his good experience on them. So I fell in love with the ES model and bought my first 2 inverters (SPF 5000ES) to be installed for a client as an upgrade from his previous nightmare YOHAKO, the 2 inverters were installed in parallel, after 7 months, client didn't find a use for 10kw inverter, so one was traded for more solar panels.

NOW, here was my observation.

When the decommissioned inverter was installed at another client's premises, the inverter will not come on with PV alone as designed, so I thought maybe it's from my installation, but i knew 100% that my installation is OK with no issues. For the inverter to work, it must be connected to battery, switched to ON position, then you will see it charging via PV. But if it's connected to battery and in OFF position, the PV will not charge your battery until you put it on. You may now put it back to OFF position when the charging starts, but if you switch off the pv breaker at this point and switch it on again, it won't charge until the inverter is back to the ON position.

The client didn't know this and thank GOD he has enough battery bank to take him 24hours, so he might never witness this issue.

While feeling unsatisfied and thinking a damage has happened to the inverter, I went back to the previous client that traded it out, on a maintenance note, I tried the system with same sequence, it wouldn't charge unless I follow the sequence listed up here. so they both suffer the same challenge. While google searching and thinking of a way forward, I proceed to buying 6 units of the Growatt model again, for 5kw installations in 3 premises and 15kw parallel installation in my personal site under construction as at that moment.

I will write further on how those ones went tonight.

I left this as a draft earlier during the day, but thanks for the assist.

adrusa:
You can mix the lithium batteries. The BMS makes each battery behave like individual cells and allow them to go at the pace appropriate for them.

With your 10KVA Growatt inverter there is almost zero chance of upgrade as it may have appear you may have exceeded your configuration due to your much PV (27 Pcs).

It is best you get an external charge controller or change all your panels to bigger wattage and a simple design this time around in two set wrt the two MPPTs

carreport:
Good day,
i need advice.
I have the following setup:

8.1kw Solar Panels (300w x 27)
10kva Growatts inverter
10kwh batteries x 2 (2 nr - felicity lithium batteries)

I want add more solar panels/increase the my PV array to 12.6kw
and increase my batteries size from 20kwh to 30kwh by adding another 10kwh felicity batteries.

The old setup is about 18 months old, i'm just wondering if it is wise to mix old and new lithium batteries after 18months of use.

If you have not taken the plunge yet

Going for Addo/Eastman setup will do you a big advantage of 1 year warranty on inverter/2 year on battery.

You will need 2 battery for the inverter.

fatherbeeman:
Please can someone recommend a good 2.5kva inverter for me --budget. 250k
Also a good tabular battery budget 170k.
Lastly please is it possible to use a 2.5kva 24v with 1 220ah battery?. Thanks

Under standard operation PV should generate ~21.6KWh give a take if the loads are hungry or batteries heavily depleted.

Sizing of PV has always been what the energy storage capacity is + energy consumed by loads = estimated PV generation.

Trippledots:
What's the anticipated watt-hour this System is supposed to supply daily? I've always been intrigued to know how installers size PV for installations, given it's unstableness.
