So got a medium action rod mid-2017 shipped from abroad and it was a blast ... Being enjoying every bits of the adventure with it

Four different states: osun, oyo, lagos, kwara

Six different fishing spot: Ede water reservoir, river at Ogo-oluwa osogbo[Google map to find], asa river extension, Agba dam both in ilorin, Lagos beach, lagos jetty.

While at the Lagos beach, used my medium action rod and caught one decent grouper, and used a bigger bait to catch bigger fish - Big mistake of the day .... Caught a big fish alright, but that sucker peeled my line and got me stuck in the rock.... Thinking I can tire it out .... Broke my rod manuevring around it.

Nice one mate

I never had that kinda luxury where I grew up... I literally grew learning the family business but the adrenalin rush and patience with tactical thinking aroused my interest in fishing.

Great experience i have to say

Victor8st:
As I'm a fisherman from the childhood (kidding), I remember going with my father always, and to be honest, I hated so much that thing while I was a kid. No way my mother always told me that when I will grow up I will start loving some things that I've hated while I was a kid. Some years ago I had some free time, and I was like, I should give it a try, as a lot of my friends were fishing. Furthermore, thenatureinsider.com has an interesting article for the beginners, who wants can check it out, it was very useful for me. So the thing is that a while ago I was in California at the Crowley Lake, the first time there. I can brag myself, I caught about 8 Trouts weighing each from 15 to 20 lbs.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 11:08pm On Mar 03, 2021
Glad to be of help brother.

The way lithium behaves on the growatt is incredible and different from Lead based batteries, the battery stops taking charge all together.

I believe it's was originally based on Expert variants but they did in house designed and changed things to suit them ....as no float bug or whatsoever for now .... All installation done with growatt is performing brilliantly with no issue So far.

IYGEAL:
So I had my 8s1p array changed to 4s2p and acquired a 24V 3KVA Growatt hybrid inverter through @Olopan of Rendezvous Solar, to replace my SMKSOLAR. He got it for me at a price less than those I got elsewhere, and the delivery was swift.

Growatt is notably faster in charging (maybe because it doesn't require minimum input voltage of 120v from pv).




I set bulk voltage to 27.6 and float at 27.
During charging, it goes up to 27.8, sometimes 28 volts but never above that. When it gets full, the inverter basically stops taking in any power whatsoever. At this point, the pv input reads zero; meter on the battery reads zero amps. These only change when I increase load significantly.

The inverter meanwhile, apparently consumes only little power and this is significant for someone like me with small battery bank. I attempted running my 75W fridge overnight when I was using smksolar, the inverter tripped off before 2am. I have run the same fridge twice overnight and the lowest reading on Growatt is 26.2V.

On the other hand, the load reading on the growatt 24v 3kva inverter is false and the fan, although not too noisy, doesn't stop. Also, the inverter has an app which I have not succeeded in activating.

Is there a separate device with which one can read the input and output parameters?

I'm curious, is Growatt Axpert variant? I think if it is, it's arguably better than the other variants.

The effect can't really be noticed instantly sometimes

Except one goes head on to compare both in the same location and area just like victron did in Romania

From my personal experience I have discovered tier 1 trump over tier 2 in

1. Daily harvest and yearly harvest. Even if they are both the same capacity

2. They hit peak production for several times of a daily power production ..

3. Many tier 1, I observe works 58-73% efficiency of their power when at maximum and more predominant around 60-63% ... Could be more but maybe not observed while tier 2 works between 45-65% maximum that I have observed but mostly 50-55% is predominately constant

ojeysky:
Curious to see what the "tier 1" generation log looks like. I have both prime(yingli cousin) 380x7 and sunfit 280x9 with orientation a little bit more on the side of prime yet both are doing 3x easily. They do burst to 4x occasionally on sunny days.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 7:16pm On Feb 27, 2021
Except you want to get this items yourself, no pro-installer or company will sell these items for you at expected rates ...

And some of the prices above are a bit off, mostly undershot

And since you said money isn't a problem in earlier post .... All you need is just 5 bricks of sweet 2.4KWh pylontech and you have 10.5KWh ...

Which means in 6 - 7 years you will have change your lead based battery 2- 3 times and with ever increasing dollar rate ... The cost of will be like 3-4 times more if you had gone with lead based batteries

cluewebhost:
Panels : 16 x 70k = 1.12m
Batteries: 8 x 120k = 960k
Inverter: 1 x 250k = 250k

From prices here is that right? Excluding installation.

Great! please when ever you are ready ... Let's know your experience

I'd write a review to the one you brokered for me. I'm impressed by the performance, especially the charging and compatibility with lithium chemistry.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 7:01pm On Feb 27, 2021
grin grin grin

Don't have a early victory lap yet I meant usable storage for Lead based so you need like minimum of 8 batteries

Good luck in setting things up, but in case you need a pro-installer.

Kindly shot your message to contact on bio

Cheers

cluewebhost:
Wonderful thanks!

So

5kw inverter for proper charging (I think it's even better if I need to expand load a bit later)
9.6kwh storage - 4 12v 200ah batteries?
+ good panels.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 3:01pm On Feb 27, 2021
The brand's that are Tier 1 are many but I will list a few that are peculiar to Nigeria

Jinko
Canadian
J.A
Trina
Risen

As regards your storage, you will need minimum of around 9.6KWh to run your preferred loads

Problem is 3KW inbuilt charge controller will not fully charge your battery so inclusion of an extra charge controller is needed but with lithium batteries you will need a 5KW inverter hybrid to slap the solar panel on without an problem.

cluewebhost:
Thank you!

1. Yes I usually have 12 hours per day and without the AC that consumes 2kwh in 24 hrs

2. A refrigerator (100w I think the stabilizer makes it higher though), Standing fans 2 20w then LED bulbs and laptop (45w) once a while

3. Yes night time only

What brands are tier 1 (these are the confusing issues grin )

Thanks a lot!
I was thinking 3Kw too.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 10:49am On Feb 27, 2021
To better understand you

1. You have grid power fpr 12 hours daily guaranteed?

2. If you can kindly state those negligible loads you mention so as to know what's best to recommend

3. By Asleep you mean the night time right? Or just random hours in a day-24 hours


A 3KW hybrid will do the job for you and to better rock the boat well ..... With regard to solar harvest .... A Tier 1 panel will be a recommendation but incase budget is tight ... Tier 2 fit pass too


cluewebhost:
I've been going through this thread and I'm confused.

What sort of setup would I need (solar) to power this AC?

I only need it on for 6 hours when I'm asleep

It shows 940W and 4A.

The rest of my load is negligible I use 2 - 2.5Kwh a day for 12 Hours of grid power - Refrigerator, Computers etc.


How many panels would be sufficient?
How many batteries + capacity?
I assume a Hybrid inverter would work but would 3Kw be okay?

Is there anything else I should know?

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 10:30am On Feb 27, 2021
Good morning everyone and happy weekend to you.

I notice a recent trend of Axpert based tech or clones having board issues and complete shutdown, while this is sad to the users and a loss of investment

It is important to note that many of these inverters with LVD have always and have being surviving Lead based batteries before now without any issue.

My pick of the whole scenario is that all attested testimony of faulty Axpert variants I noticed here have always being with DIY Lithium based batteries with BMS .

In reality all information to draw a conclusion from what happened with the battery mostly goes down with the inverter when it went bad .... But one thing to note is that

I believe that the BMS does something that indirectly hurts the board or electronic components built-in.

My own solution to the DIY Lithium owners will be to lose some energy storage by increasing their LVD to be above what the BMS will do normally so the battery retains some energy while only your inverter goes offline.

And since it's hybrid ...once the sun comes on the battery gets juiced up.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 11:46pm On Feb 19, 2021
I'd advice that you get the following accurately

Power consumption of all you have listed below and state the hours you'd like each to run for either day or night.

This way your storage capacity and inverter capacity will be determined.

Else I am afraid you might end up with a half baked solution you won't like. So better to have a road map for things now and work towards it.

I can share with you a form that you can fill and return and I can help you at my leisure.

Happy weekend!

Good afternoon. Please, I want a solar structure as well as batteries for my household appliances( TV, Fans, bulbs, deep freezer, fridge and other minor appliances). But I want the fridge and freezer to be always on (24/7) while every other appliance can be average of 12 hours per day. I'm thinking 4 batteries of 12v200Ahr, 6 mono crystalline panels of 200W and an inverter of 12V2kva will do the job for me.

Please, kindly advise on how to go about it because it's urgent. Thanks.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 10:49pm On Feb 19, 2021
Easy fix

Loosen the back of the fan and located the moving parts, get a good oil that won't evaporate on heating of the coils and carefully apply it on them.

Couple back gently and power it up.

You should be back enjoying that cool breeze smiley

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 10:39am On Feb 19, 2021
It has a good idle consumption on no load

7-15W

And when like 70% or close to max. Load.

30W - 100W Or less

IYGEAL:
Well noted.

How about idle power consumption?
Can it work without battery?
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 1:24pm On Feb 18, 2021
What I meant was that the 600W PV you have will never charge your batteries full any day of the year

Except you have grid available for up to 18 hours cumulatively then it's no problem at all.

Just watch closely

These equipment ain't cheap so log your information to be sure to know when something isn't looking right

durodee:
Good morning house, I was recently faced with a challenge. I have a 24v 5.4kwh LiPO4 bank and a 600amp 24v used Ritar battery bank. Tested alone the LiPO4 did not meet my daily need. It will usually go off around 2-3am (when I personally need it most!) and the used batteries much earlier at around 12mn at times.
I was discussing this challenge with a friend and he told me he connected his LiPO4 and SMF bank together(in parallel) to the same busbar and that has resolved his problems.
So I checked online https://community.victronenergy.com/questions/19981/mixing-lead-acid-and-lithium.html and realized many others have tried it with the pro and cons, different charging and discharging profiles mainly.

So I connected 200amp of the Ritar to my lithium bank to test run. I also used 28.2v bulk and 27.4 float charging profile on my inverter and CC. All connected yesterday evening. I was able to use the system overnight and even ironed with it this morning, however I was aware there was grid supply at some points overnight and therefore I can't say if it works or not.

It is early days yet. The risks are shortening the lifespan of the lithium and undercharging the lead acid but based on what seems to be happening as described by others, due to the BMS, lithium charges and discharges first and the lead acid charges and discharges last.

I will update the house on my experimentations and hopefully, no big bang episode! grin
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 1:20pm On Feb 18, 2021
Easier if you have your connection reconfigured

Assuming you used 150W which has up to 23V as VoC

Choice is all yours to make.

Growatt 24v hybrids I see can't take my current 8s1p PV voltage input.

I may have go SMK again or get a standalone 24V wall mount inverter and a separate CC.

Any suggestions house?
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 1:17pm On Feb 18, 2021
1. Remote monitoring

2. Configurable parameters

3. Lithium compatibility

4. 100V max. For 24V variants

5. Up to 1500W max. power, over sizing is allowed

6. Atheistic design

7. A medium range product for money.

In case you plan to get one, I can hook you up.

IYGEAL:
Why though?
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 7:46pm On Feb 17, 2021
Give growatt a shot

IMO

IYGEAL:
Battery is a standalone 24V, inverter is also 24v.

Tried feeding PV and also experienced a spark. Took it back to the repair guys to try their luck.

So I'm on the look out for a 24V 3 to 3.5kva hybrid inverter which would preferably have a lithium profile.

I need opinions on which is better between Growat, iCellpower and Sorotec. I think my preference would be the one with less idle power consumption and less minimum pv input voltage.
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 11:44am On Feb 17, 2021
Yes.

Rated to your needs

IYGEAL:
Do you mean circuit breakers?
Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 10:55am On Feb 17, 2021
What I have learnt is if the arc is too much something isn't right.

And from your explaination below, I guess you don't have a battery disconnect too

Just for the sake of when you have it fixed and returned, please kindly get them Disconnectors as to proceed with ease and enjoy your system

IYGEAL:
That may be possible but very unlikely. The sound was reminiscent of a capacitor forced to discharge.

What the inverter does now is produce a massive spark on trying to connect it to the battery. Sometimes it shorts off the battery. The sparks are big enough that they almost washed off the threads of the battery terminal.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 10:27am On Feb 17, 2021
Yes I can it but "never" Efficiently because you need like 600W for every 200Ah of battery and considering you want to use 4 batteries

600W x 4 = 2400W ideally
But in reality you might want to over size not more than 150% if using Tier one or 200% of charge controller if using tier 2.

All the above depends on your pocket, grid availability, and last aim of use etc.

Checked throught your recent post, if you have not bought that inverter I will recommend Growatt for you can handle over sizing too and sure will charge your battery with no stress.

Satellite TV TechnologyRe: Solar Energy, A Complement To FTA by olopan(m): 10:16am On Feb 17, 2021
Sorry about your inverter going bad but the scenario you explain feels rather weird to me.

The PV wasn't say energized like when the sun was up ....so power wasn't suppose to be coming in.

I have been to site with no PV disconnect for conventional charge controller and disconnecting the PV while operating " though bad" never had a fireback or otherwise .

My educative guess is that the PV input and BATTERY might have a kinda common bus .... So maybe on removing the cable some tiny strands bridge the +ve and -ve.

Just my opinion. .....

IYGEAL:
The silent y before s is probably also physically silent cheesy

I was going to make these adjustments but it looks like I have carelessly fried my new hybrid pet.

So I was going to shorten the PV cable last night but forgot to switch off the inverter. Breakers I ordered are yet to arrive so there is no breaker between the inverter and PV. There was a loud sparkling noise the moment I put a screw driver to unscrew the PV.

Sent it to repairs but I'm guessing the board is gone and I might be on the look out for a new 3.5kva hybrid.

I believe there are Engineer and there are engineers

As a basic knowledge potential difference - P.D
potential flows from higher to lower P.D


For a PWM that works on pulse modulation, something slightly above the Battery voltage is considered the sweet spot.
E.g
18V for 12V
30V for 24V
50+ for 48V

Anything out of the above equals a system that is inefficient and poorly designed.

solasola:
I have seen lots of discussion on pv setups, 2S2P,6S2P....... I think such setups cant work for Pwm cc and simple inverters with either 12v/24v operational voltage.
I am asking this because i have come across a system like that the client said failed. I noticed pv was reading about 56v for a 24v inverter. Going up, is saw that 3pc of 100w were connected in series pv wires were corroded with whitish powder, cc was bad, batteries were overheating too and one was melting sef.

The client had to rewire the pv wire since they were badly damaged, buy new cc, change batteries, opt for a 12v system, and has enjoyed his system since then.
