Hi All. I am using a famicare inverter 1kva with one 200ah battery. Whenever the battery is full, immediately it starts charging again. This happens intermittently several times. Could it be battery or the inverter?? Also, how can i prevent low/high current from damaging my battery/inverter??

If it happens intermittently after full charge then it's called trickle charging to prevent the battery from draining. This is good for keeping the battery at full charge, though I'm not aware that famicare inverter comes with this function.
Famicare is a low wattage inverter, you could prevent it by connecting through a stabilizer.

Thank you very much for this. I really appreciate. So i can relax knowing well that my battery/inverter is fine with the trickle charging??

Recently concluded Solar upgrade

New Installation

Well done boss
2 clarifications please
1. Can I get fairly used 200w poly panels, and how much?9
2. I read this thread all over again, you mentioned some 8kw modified sine wave Inverters that can power all loads including freezer, how true is this, since they are modified sine wave inverter

200watts poly cost 30k each.
For the fact that an inverter is modified sine wave does not mean it can't power heavy loads, it only means the quality of its output power or wave quality is not purely sinusoidal. This can only be detected by some highly sensitive loads like computers etc. I have used a modified wave inverter to power Air Conditioner.

Many thanks sir

So sorry for the late reply. In theory, i will say the New 100ah battery is preferable but based on experience, i will say so may variables needs to be considered before a decision is reached.
1. How long has the 200ah battery been in use, was it abused or well maintained
2. Is the New 100ah battery premium brand or the common china battery
3. Is the Used 200ah battery premium brand or the common china battery
4. What is the weight of both batteries, the New 100ah should be above 30kg and the 200ah should be above 61kg
5. What is the cost of both battery and so many other questions

I sell a lot of Used batteries, if you look at my thread, i call them fairly new because they are always in pristine condition. I also sell New 100ah batteries. This is a very difficult question to answer but if i could get answer to the above questions then and only then will i be able to advise on the better one.

Thanks

Do you have fairly new batteries in stock now?

Also add that it generates relatively more heat when used to power inductive loads like motors, fridges, ACs.. Etc

Wow so it can work well powering a fridge, without the fridge developing faults later?

Throw little more insight on it biko

Besides generating more heat any other downside using modified sine wave to power fridge.

Electronic service life will reduce, Fire hazards., lower efficiency on some models resulting in significant loss of usable electrical power.

This doesn't look good. Thanks for ur insight

It's better to buy one of these cheap pure sine wave inverters from AliExpress. Delayed shipping due to Corona virus is the only issue now but some orders I made in March finally arrived this month.
So if you can wait, place the order, take a big chill pill and wait for it to arrive.

Hi Bro,
I need to make some enquiries pls on getting an inverter from AliExpress you talked about
Thanks

Hello, you can ask me any question here.

Hello, you can ask me any question here.

Oh! It's aiiit, no probs,
I just wanna ask as regards shipping inverter from AliExpress, how did you go about it considering the shipping price is always high,
I saw you advising someone to get one of those cheap pure sine wave
inverter from AliExpress
And if you have a seller that is reliable with better products on Aliexpress, I wanna ask for the liñk.

Iamsane:


Do you have fairly new batteries in stock now?

Yes, 200ah at 50k each

Trippledots:

I absolutely agree with this

Trippledots:

I tend to disagree a little with the Fire Hazard thing. All electrical/electronic appliances could cause fire if abused. I have never seen a modified wave inverter burn cause of its wave quality except of course there's been an abuse somewhere.

Thanks alot for your contributions. Really appreciated.

The shipping price is only high if you are buying large capacity inverters that have a lot of weight. I bought a small one last year (600w pure sine wave) and shipping was cheap (less than 3k).
I don't have a particular seller I buy from. Just search for what you want and order from any seller that has it. Worse case scenario is, if the product doesn't arrive, you will be refunded.

Pls, one more thing, can you share the name and the pix of that 600w pure sine inverter that you got

This is it (First screenshot) but the store no longer has it and the shipping fee from other stores is crazy.

Go for the one in the Second screenshot. Just type "1000w pure sine wave inverter" in the search bar. It is among the first 6 results you'll see (Third screenshot)

Please, since it's pure wave, can this power a freezer of 110watt?

The inverter has a peak power of 1200W for a few seconds so it should be able to handle a fridge of 110w.

Hello Boss, some of the reviews I read on the inverter said the fan makes a lot of noise and it's like the fan is always on, no time it is off. Pls, what's your experience so far?

Mine is different from the one I recommended and the fan doesn't come on until load exceeds 50w.

Did you find those reviews on AliExpress ? 'cos the one I recommended doesn't have much reviews.
