Low voltage protect kicks in at 21V but we do not advice our clients to go below 23.5V

Oh nice.
Also, please what SoC / DoD would you recommend it be run to?

Thank you brother.

olopan:
More power to your elbows, I see this with more improvement in the future ... Well done

ojeysky:


Did they write 12.5kwh on it or 280AH? because 280AH should give a little above 14KWH. This is not a bad deal if it's truly 280AH

Yeah they did.

Good day all.

Please I need a good used Quanta SMF-VRLA 12v 200Ah battery. One of my batteries is bad, and want to buy this to complement the good one while I prepare for purchase of new set.

Let me know if you have any in stock.

Is this a good device to buy for a DC 20V standing fan If one has 18650 batteries?

Nice one on thinking of adding solar to your installation

BTW a 600W solar panels connected 2 x 300W on an MPPT would great as
1. You have used the sized panels to charge right

2. 40A is recommended at 12V max. Output is 520W anyways oversizing of 80W got nothing on you

3. Please note that for a 12V system... Expansion isn't as dynamic as higher voltage systems.

Hope this is helpful..

Thank you so much for this,its really helpful. Pls can u recommend any good brand of mppt cc and panel . Thanks once again.

✓ Are they brand new 18/65/0 cells?

✓ Soldered or spot welded?

It has adjustable voltage from 5v to 21v I think. So you need to put the voltage out at 12v else you risk burning your fan rotor. It's good but the battery case is expensive for my liking. Another good side is that it can be charged comfortably by 18v solar panel or laptop charger. And it should give you enough backup at moderate fan speed.

God no go shame us.

Experts in the house, pls why does a solar set up harvest more when in use ( I.e loads on them are on) than when they are not in use ( I.e when loads on them are off)?

Because your battery has taken what it requires (to charge) and the panel/cc still have more to serve your load

Simple when load is on the panels it provides current or amps for the load you are using and also tries to charge your batteries the same time. It is only if your load exceeds the current generated by the panels then some amps is depleted from your batteries to add to the panels current.

Okay.

Thanks

Thanks for the explanation

Smart solar charging is a 'demand pull' application. Given optimal conditions, a 300w solar panel may be able to produce 230w but only produce say 30w while the battery is float charging and no loads on. Turn on a 200w load as additional demand and the CC will soon ask the panel to release 200w extra if it is available.

If there is sufficiently large load and/or battery charging demand, the panel will produce its maximum capacity for that given ambient, tilt and solar irradiation condition. Reduce the loads and/or battery charging demand and you will see the solar production drop too.

Simply, solar energy cannot just be created in a vacuum, there must be a load (house equipment or battery) requesting and consuming that energy.

I'm equally interested in the answer to this question @justcallmenuel
Try dey post exact specs of your products, preferably with pics of the nameplate.

Exactly.

Electricity 101. What any electricity source gives out is dependent on demand. And that is why our appliances don't get burnt by the power we supply to them. Irrespective of how much current your source is capable of supplying, your appliance will just take how much it requires to function. That is why you can use a charger rated at 100A to charge an appliance rated at 10A. Only the voltage must be within acceptable range.

True but he can do a nameplate picture. Why don't we get "REVIEWERS" in Nigeria who can really test out these things and give out their correct ratings?

Anyone has a used 10kva/12kva central stabilizer that picks from 80v or even lower sef?

still available

First, your load matters most but with that inverter capacity, 750w panel is too small. I will suggest you change your inverter to 1.5kva max or increase your panel size

They come in 10Kwh (200Ah) and 12.5Kwh (250Ah)
