I swear it's too much ooo. Most times I check the Inverters I see each of them frying about 4.5Kw from the 2 strings of panels respectively. So I know the system is capable of delivering that much power so I feel bad when there is nothing more to power up in the house to consume the excesses.

Tsuccesssquare:
Thank you so much for this breakdown.

The battery part looks a bit confusing, are they in parts?

jonescosmo:


They are not being compared boss, But if I may comapre them, I have a 5KVA Inverter, 8 Units of 220Ah Tubular (21Kah) setup in my Office. Backing up just my Server, Switches and CCTV. A total load of about 2.5Kw max and the Battery Backup Time is nothing near that of these Lithium Batteries with a wooping load of almost 7kw.

In all honesty. Tubular batteries did well during their regime but the game has changed. Lithium has taken over.
As we speak several combination of Lithiums are in production (See Table) but lets just stay on LiFePo4 for now.

FEGEITOK:


Thanks for sharing.

Learnt a lot from your post

isangjohnson:

I guess your 7kw load draw was done by the huge pv on your roof and not the battery.
If the rated battery capacity was in order, I you may still have pulled out 7kw load on it for about 2hrs and 20 mins... that's if I'm right.
Again, we're still waiting for the confirmation report of your battery capacity test.
Congratulations once again.

That site doesn't load unless you have a VPN enabled.

Nice stuff you got there.

FEGEITOK:
Does anyone here have several inverters connected to the same battery bank? If yes, why did you set it up that way?

I have two 5kw Growatt connected to single 30kwh lithium bank. Why did I do that? To increase the capacity of the inverter and also so it can handle the number of solar panels in play.

jonescosmo:


I guess you are talking about a Parallel Setup.

You can post Pictures so that we can understand ourselves better.

samir101ng:


From your quote above, there is no brand name given for the solar panels, inverter and batteries. It's why in my initial post i suggested some brand names for every component listed. If you want a kind of complete setup, then you can consider a setup from Luminous https://thesimbaden.com/ or from Eastmann https://eastmannigeria.com/#. They are both Indian brand of inverters and can offer you a complete system with warranty. Check the websites for their addresses and give them a visit. But the brand of your components is not listed here and therefore we cannot vouch for the quality or price.

Please, is your Growatt 5kw an ES version?
What's the no load consumption?

Namzy:

Fan comes on during charging and off in float, also comes on on high loads. My Axpert inverter does same too. I guess most Chinese inverters do same while charging. If your light is blinking, then most likely your inverter has not entered float. You might be depleting your batteries more thereby requiring long charge times hence while your fan is always on. For lead acid batteries don't go below 50% infact I've gone slightly below 65% once in my 4 years of using my tubular batteries and batteries are still flawless. So end point is get a battery monitor to know your battery soc and properly monitor your inverter charging profile and battery well being properly

Thanks man.

My 24v 5.5kva inverter and 4 tall tubular battery setup na tear rubber oh.

I haven't started using it for carrying load sef. That's why the whole thing is confusing me.

I was told to leave it charging for at least 24hrs which I extended to 48hrs but still the fan go just dey blow dey go while the charge LED light stays blinking but the battery meter on LCD is full and voltage is 27V (It's a 24v 440AH setup).

I assumed it was already in float since the voltage is reading 27V but that charge blinking thing

Do I need a separate battery monitor DESPITE the inverter LCD screen already showing Input Voltage, Output Voltage, Load and Battery Voltage etc ?

Voltage in my area these days dey tire person sef (120v) and has me considering a very wide range input 10KVA stabilizer

Tsuccesssquare:
I did visit Eastman office yesterday as recommended, they had only inverter and batteries in stock, no panels.

Also, they don't have the 2.5KVA available, the ones close available is 2.2KVA and 3KVA

Below were prices I got.

2.2KVA infinity Inverter - 150k
2.2KVA Eastman Inverter - 153k
3KVA Eastman Inverter - 218k

200ah 12v Eastman Battery - 195,000
220ah 12v Eastman Battery - 210,000.

Battery monitor will give you the correct soc all things being equal. It has a shunt that measures current inflow and out flow through which it calculates the battery percentage. Your inverter battery bar might be full and then suddenly shows 60% or lower when you put a big load on it, only for it to show full again when the load is removed

ojeysky:
Have this 200a DC meter with shunt available for sale @15k per unit

ojeysky:


I still have these battery monitors available for anyone interested. No change in price

You guys are yet to help me out with the right inverter I should purchase for my inverter journey. Am a newbie here.
I like studying and making lot of inquiries before starting any personal project even though am not interested in diy. I will call a professional to do my installations once every is bought completely
