200 Ah requires max 20 to 25 Amps C10 rate batteries. Anything more and you will damage the battries unless the charger can adjust current and monitor temperature .

If you are willing to order from Aliexpress I can send you link for a very good charger . or altrenatively look on this website and find a way to order http://www.meanwell.com/product/inverter/inverter01.html

I found it very difficult to locate a good charger at that capacities as normally it is integrated in inverters

i think ur system is improperly sized.
a good setup has 3 to 5 days redundancy built into the batt bank.
i would prefer that to messing with and installing a wind turbine.

@samnaija..i still think ur best bet is to change ur 12v 500amp batt bank to 24v 250amp bank...just playing with series/parallel connections..........abi its just a single batt of 12v 500amp u have?!!!......wahala dey if so
its the same thing and ur runtime would still be the same.....that way you only need to get a good 24v inverter capable of pushing out 30amp.......same goes for the charge controller you intend to buy...45amp morning star hooked to 1kw 24v panels is ok...or 60amp epsolar cc hooked to 1.5kw 24v panels...........u dont really need an 80amp cc

The measured SOC is not extremely important. It does not always reflect the true state of the battery. It is at best an educated guess based on input and output Ampere-Hour. When the inverter "calculates" that it has returned the removed AH, it then registers that the battery is at 100% SOC. This is not always true. I will say dont worry too much that you are not seeing 100%. It doesn't matter too much. Your voltage of 13.8 is about right for a floating battery. What is important is what voltage do you get some hours after NEPA is off and not on load? What voltage do you get when the inverter is supplying power (on load) without NEPA?

About 13V (12.8-13.2V) is fine when the battery is at rest without NEPA or load after a few hours. When you put a load on the battery, you should start off with about 12.6V (12.4-12.7) depending on the load. If you are seeing less, you are either putting too much load or your battery did not get good charge.

In my opinion, it is something that you have to personally study to see if you are getting the best out of your batteries. You can only get generic advise here, but each inverter/solar system setup is unique. The voltages you will see will depend on your usage scenarios. Finally, what equipment you are using for your measurement will also affect what readings you are getting. You may need to calibrate your voltage reading if your inverter supports that. You will obviously need a good clamp metre to do that.

As to solar support, it will depend on how much NEPA do you get per day. What SOC/Voltage do you get to in a typical morning after overnight use. It is presumed that solar will charge your battery for about 4-5hrs on good sunny days. You can calculate how much solar you will need based on SOC/Voltage of your battery in the morning and what current (in ampere) will you need to put your battery back to full charge in about 5 hours.

kevin brand?...sounds like a local inverter or indian etc..anyway...going by battery basics wch states minimum of 10% of ur power bank capacity if the the charging requirement...thus you need a n inver ter or charger that can kick out 50amps at 12v minimum.......best sef is one tht can do 70amp........using an external charge r isnt a feasible option.
either change ur inverter to >50amp 12v type or you change ur battery arrangment to a 24v 250amp bank...n then get a 24v 30amp inverter.
you shud b fine either way

oh i forgot....with ur present setup same thing applies...you wud need a cc/panel config to give you upto 50amps or best 40amps --gurus share ur views on this solar angle

c0ogumo:
Please answer the following questions;

Why cant your inverter fully charge your bank?
What is the brand of your inverter and what is the charging current?
Why is your inverter bringing the bank to 97%? why not 100%
Are you looking for solar to fill the remaining 3%? or to charge from 50% DoD to full?

SO I finally had time to install the epsolar CC i bought from kie kie, _{at a price higher than what i budgeted for, ..well thats a story for another day}
compared to morning star , this epsolar is huge!!!!.....though it appears to have more functionality than the morning star, but kinda still prefer my MS.........time will tell.

reconfigured my 24v 250w renogy panels to 2 x 2 , thus input voltage into cc is about 65v, which drops down to about 55v when hooked up to the cc-inverter/battery system...
harvest looks very promising........will monitor and keep the house updated.....recorded 730w harvest from 1kw panel..that arent even optimally placed.......anyway max i got from MS throughout the 21months usage was about 750watts, lemme see if this epsolar will exceed that.
nb: disregard the time on the cc, hadnt set the clock properly then!

Kie kie delivered very very fast...item was in my location barely 15hrs after payment

Some churches go way out of line . Some even put speakers outside . For God sake whoever want to listen to your sermon should be inside . Nigeria is not only a occupied by Christian so we should leave to respect other people's religion by not provoking them with our activities . Most of the churches fogey they are even in residential areas . It's not cool . I'm a christian but at the same time I feel the man
