Do you mean Famicare inverter or Famicare charger?

What are recommended charge voltages of the battery? You can get them from the body of battery. Snap and send to us.

Famicare inverter. Recommended charge voltages of battery is 10.8v - 13.5v

Between Growatt inbuilt MPPT & external Victron Charge Controller which has a better charging algorithm.

I use Victron 250/100 CC in my village house and I can tell u that they beat Outback CC 100 to 1 in terms of charging.

Interesting numbers (in bold), Outback strikes me as a very good CC am curious to learn about the test you carried out to confirm this major difference?

I had similar high rating about Outback but I finally learnt that they are over rated. I personally bought 2 of them from Amazon in US due to its high ratings.

Now let me give u my layman experience.

There is usually PHED in the morning around 7am till like 9am, the CC continue to show charged even when utility is no longer available. So while the sun is shining the CCs are sleeping and the inverter is busy draining the batteries. By the time the useless Outback CC kick in around 2-3pm it will not be able to charge the batteries till they float or absorb. Most times by the time my wife returns from school runs the inverter has shut down due to low battery.

However the Victron CC I have in he village moves quickly from float to Absorb and then bulk within few minutes when utility is no longer available and the AC is on. It makes the batteries remain fully charged till 5-6pm most times 6:15pm.

So I have learnt not to joke with little details. They can cost u a fortune.

From the bolded, I want to assume you've ensured this was not a settings issue? If yes then I will say that is a huge bug..... Even a cheap powmr will not behave as such

I have tried all manner of tweaking of the settings, watched countless videos online, increased the voltage setting to enable the CC kick in from 51v removed the external temperature sensor pluged to battery terminal etc. I don taya

The only explanation I can give is that as the batteries became weaker the CCs misinterpret the readings coz at 45v any CC with common sense is suppose to start charging.

@kadorzy I think used the junior brother of outback before, maybe he can chime in here... really I do think it's absurd and strange for such a CC to behave that way.

You are right it sounds like a setting issue.
Outback original!, me I use the clone fangpuson what he complained is common with the clone also. The cc can be in charged setting and not delivering current when battery needs it. The setting na war, wake up voltage, absorb voltage, reabsorb voltage , you have to try and get it right .

THATS serious flaw, i wonder if its limited to yours, or thats the general behaviour?..
fangpusun flemax, the outback clone, doesnt behave so

I never experienced such after over 5years before I retired it for a hybrid system.
Well you can try your luck with the voltage setting calliberate to match with actual readings from an accurate multimeter.
You just need to tweak it to get it right.

No I have Fangpusun CC (the outback clone) in my guest house it doesn't behave that way but it takes some time for the CC to move from charged to Float then absorb/bulk charging unlike the Victron.

So basically I want to be sure that the inbuilt MPPT CC of a Growatt is OK or I should go for an external Victron CC.
Please I need user experience on this

I'm done with outback.
U won't notice this issue if utility is unavailable through out the nite, the CC will work normally its only when utility makes the CC not to start up in the morning. It's not an every day occurrence but my careful eyes caught the problem. My worries quadrupled after I observed how my Victron works effortlessly without human interference

A few places I have deployed growatt are doing fine....I don't use it personally. For me I prefer an hybrid system.....but one man food is another man's poison....we've had a long talk on hybrid Vs standalone in previous thread

This is the setup I have in the village.
I have a 5kva hybrid Felicity inverter but I didn't use the MPPT rather I installed an external Victron 250/100. This has served me well. I read on this thread back then that the charging of hybrid systems were not comparable to external CCs so I just want to confirm if that has since been improved on...

When I used MPP and Felicity hybrid charging was fine and now that I just Deye hybrid charging is still fine. Ofcourse there may be little difference in their mppt efficiency but not more than +/-5% IMO

Please, Can anyone help with list of batteries that LAST 5yrs and above and their current prices

And batteries that can LAST 3yrs and above and current prices


Reason is because my current battery is draining fast and is not up to 3yrs that was stated.

Battery =JYC battery GP200ah-12v
Panel. =2 pcs of 260w solar panel.
The inverter is 1.5kva

Loads. 2 ceiling fans, 1 TV, and 6 bulbs.( we don't on all bulbs)
We don't know how we use it wrong to avoid that in the future

Please someone should help me with this, let me know where I went wrong in usage before buying another battery.

Get LFP battery packs and have peace of mind or if you still want to stick with LA, get any popular brand from reputable sources and make sure you don't frequently discharge below 70%.

Iam using the New Victron 450/100 it is a fantastic CC and so wonderful when you hook it up with the Cerbo Gx. goes to sleep completely around 7Pm without drawing any current and wakes up around 6:15 in the morning because of this i am completely to team Blue, have gotten 2 Multiplus II 5000VA and changing all my gears to victron and untop as the icing on the cake the VRM can be assesed anywhere in the world. Will be showcasing the build when i start

If your ceiling fans are the conventional type, then they may have contributed to your battery's deterioration.

1 normal ceiling fan is 60 to 80watts...will assume 70 watts, so 140 watts for the 2
tv is about 50 to 110w...will assume 80 watts....your cumulative wattage if you add the bulbs will be over 250watts. lead acid isn't happy when you load it over 10% of its capacity. This ur load is over 20 percent already,

YOur battery JYC is likely not a decent, Make, never heard of it b4.
a 150ah minimum should serve you better....or if you must do leadacid...do 2 pieces of 200ah in parallel, or 150ah if funds are tight.....that would also require an increase of your panels to 4....more wahala.

a switch to lithium battery doesn't require any other change

i feels ur pain...i was shocked the first day i saw my flexmax sleeping when i needed charging during a good sun-day, moreover this issue had been discussed and resolved few years back for flexmax users.
i had 3 flexmax (two 80A & one 60A as backup)i did some reading & tweaking of setting to over come the sleeping of
the CC since then it has been enjoyment galore. you have a wonderful machine though not modern to say but it can get the job done. i will advice u dont waste money on another CC unless u prefer modern toys.
whatapp me on zero8zero34three87threeone1 to walk u through tweaking it. you can thank me later.

There is usually PHED in the morning around 7am till like 9am, the CC continue to show charged even when utility is no longer available. So while the sun is shining the CCs are sleeping and the inverter is busy draining the batteries. By the time the useless Outback CC kick in around 2-3pm it will not be able to charge the batteries till they float or absorb. Most times by the time my wife returns from school runs the inverter has shut down due to low battery.

However the Victron CC I have in he village moves quickly from float to Absorb and then bulk within few minutes when utility is no longer available and the AC is on. It makes the batteries remain fully charged till 5-6pm most times 6:15pm.

So I have learnt not to joke with little details. They can cost u a fortune.

Please I am in need of several units of genuine tokumbo 200w - 300w mono solar panels.
Kindly recommend a trusted seller.
My search on jiji has not yielded anything reasonable. Came across some clearly "re labelled" panels. CanadianSolar (made in Canadian) and other labels with tell tale signs of being fake.

If you are a seller in the house, kindly whatsapp me on zero-eight-one-two-three-four-five-4250.

I think Zeestone sells panels. But I don't know whether he sells used ones.

Might need to set the Re-bulk voltage well

Right now solar energy is taking a very important path, rather clean or renewable energy is the one that is having great importance for people, with equipment such as the Portable Solar Power Box, it is placing the interests of investors at the beginning of the chain is one of the best things that can happen in the century.
