Dropping small backup setup with 230ah lifepo4 for someone that may be considering it.

230AH 12v setup
- 4units of lifepo4 320k
- BMS 4s - 50k
- 540wx4 panels - 640k
- High V 1.5kw inverter - 110k
- Cables and other - 40k

230AH 24v setup
- 8units of lifepo4 640k
- BMS 8s - 50k
- 540wx4 panels - 640k
- High PV 3kw inverter - 210k
- Cables and other - 40k

With the above you should be good for at least 6 years (subject to natural occurrences/incidences).

Have a good work week ahead

ojeysky:


If you have a load below 500w going 12v makes more economic sense...by the way kWh is not unique to lithium it's a unit that is applicable to power measurement

But, if you ever plan to grow your setup, it is better to do 48V. I started out with 24V thinking about the cost of battery. I ended up moving to 48V when I scaled up, but I was stuck with a high-end 24V inverter that I couldn't dispose at a good rate.

That's right indeed....anyone planning to upgrade in future should just procure the inverter of the future if budget permits cool

A short review: A low budget value for money. Need an MPPT CC with the most basic Interface but keeps working? Then get this!! PowMrI have 3 of them in use. Works well , relatively cheap and can work for 12,24,36 or 48v systems. Works with Lithium batteries and
lead acids variants. Excellent as a back up CC too in case you need one to fall back on. Planning on getting another one soon.
Cons? Plenty grin!
1) No log Interface to record daily harvests , so difficult to know exactly how much you are harvesting daily. I have to rely on other ways to get this.
2) Connect points are a bit small and take max of 6mm cables
3) the supplied screws to attach the CC to the wall sometimes are too small
4) Price is getting high nowadays cry

Good morning all,
Please I am planning to go green and need your input on which is a better option between flooded and AGM/SMF batteries as I plan on getting it.

With the proper maintenance (battery rotation, equalization, etc) which amongst the 2 will last longer (I can't currently afford to get a new 24v lithium bank).

Proposed set up.
1. 1.5kva 24v luminous hybrid inverter
2. 4x 350W panels
3. 60A Techfine or Powmr MPPT CC
4. 24V 200AH to 305AH battery bank.

Any other other advice will be very much appreciated

Thank you

FLOODED WILL last more than smf, epsolar mppt cc has inbuilt 30day programmable equalization, so its abetter choice...i dont know if techfine has it as well, powmr doesnt have it.

why are you going for luminous hybrid, since you are planning on using standalone cc?, why not save money and go for the cheaper non hybrid inverter??.....again you say you would go for lithium in the future---if so you need an inverter with editable charge voltage settings.
sorotec 24v 2.4kw hybrid with inbuilt 4kw mppt cc would have been the best for you if you can see it, costs about 200k. has everything u need now and for future expansion

Is anyone here using DC freezer

what is the main reason you want to buy a dc freezer?.......
if its for energy savings dc freezer consumes about 70w, while ac of samesize is about 120watts.
purchase price of dc freezer is about 2x of ac type.

repairs::: would the local repairmen be able to work o them, on the off chance that it developes a fault?

would recommend you buy the type that has an ac adapter...so you can switch to ac--shud you want

Hello bro, pls I am a novice here and I don't know what and what exactly to get. I want to power my 40" smart TV, 2 ceiling fans, 4bulbs and charging of laptop and phones though, pls i need an advice on what to get in terms of battery and inverter. Though i live in a rented apartment, is it advisable to install solar panels? I read a comment here where som1 was saying he doesn't want to get solar panels because he lives in a rented apartment.

Well we don't know the voltage of his panels.

ahh, you are still on this matter.. he said his array is 600w, so its likely 2x 300watts or 4 x 150 watts, or 6 x 100 watts,. max voc of 300watts panel is about 41volts, max input for the avg pwm 12v cc is 50volts.....so don't see how his panel voltage would be an issue.........

Split d wire bristles in two since there are 2 ports each for -/+

U need just a very tiny nail to hook it up. The type dat comes with wire holders to wall ( i don forget d name). Just two will do a good job from d top points only.

Powmr is quite dependable but always try to confirm that the display voltage matches the output, sometimes they're usually off by few units.

For the old powmr, you can use 10mm, split it and connect to each of the dual terminals.

The new model's terminal should take 10mm with ease.

Can you share what u use for logging data for daily harvest, it would be appreciated.

Secondly, for your connection point you could use wire connectors as shown in the picture below, that way Ur connection is neat and tight though crimping with ferrule connectors is more ideal..... Cheers

Re: Solar Energy, A Complement To FTA by durodee(m): 9:30pm On Aug 29
Thanks for the advice.
The ways I judge the possible output is quite rough. One is through the BMS of my Lithium battery/batteries attached to the Cc. That do not cater for losses from using small gauge wires from Cc to battery BUT gives me the actual amp that gets stored in my battery. The second method is back deduction from my inverter (Gennex) that has the capability to log stats on imput and outputs. For example if the inbuilt Cc says I generated 5kwh and the output energy was 8.5kwh, I could therefore duduce that the rest came from the PowMr

NiyiOmoIyunade:
For a 2 battery setup you may not stress over an elaborate scheme - the odds are in your favour.

Just make sure that you charge the batteries to full standalone before you put them together in series (assuming you wanted 24v) and then equalize regularly

If you are not locked in yet as per purchases and have no plans to expand by a lot anytime soon, then a 12v inverter is pretty good and takes away all your concerns around battery balance.

One thing that kills tubular batteries quickly is that they need a higher voltage absorb charge than your average basic inverter can provide, if you have solar then this can take care of the problem somewhat.

There are decent MPPTs that will work well for you even at 12v and affordably priced.

Regarding the emboldened;

You will notice that there are 2 inlets each for the positive and negative terminals for the PV array and battery(ies). If your cables are too large to enter one inlet at a time, you can split them.into the two provided inlets for each terminal. It works that way.

This present version of the PowMr Charge controllers will go out of production on or before first week of next year as it has now been replaced by an improved version.

This new version can accommodate more panels and the heat dissipation feature is more better.

I will have it in stock before the end of the year, and I am working to maintain the price point of the old/current version so that customers can at least have more value for their money.

Meanwhile, i recall delivering one unit of this current version to your acquaintance around Obanikoro on your behalf. Thanks for your patronage, sir. Please let me know when you need another unit and i could provide you with some discount.

Nice Review smiley

This is a basic solar charge controller that's affordable for budget conscious people. However, you get what you pay for as it doesn't have some of the more advance features that others have. But most importantly is that you don't get the nameplate readings you see compared to using an actual clamp meter to test the real world readings. Here are links to their official stores:

1. Powmr Official Store

https://ysmart.aliexpress.com/store/609653?spm=a2g0o.productlist.0.0.533e5d4fFeAwCE

2. MakeSkyBlue Official Store

https://makeskyblue.aliexpress.com/store/1759821?spm=a2g0o.productlist.0.0.1d6e1d21dvPKn2

You can order both from AliExpress direct or any major reseller but be guided that these are chinese clones. I am however more partial to MakeSkyBlue No. 2 compared to Powmr No. 1. They have better documentation and their products are of a more higher quality. But they are both basically the same thing. As stated, they are cheap but your performance mileage may vary.

Thanks Boss for this.

I also highly recommend the use of ferrules for your connections if possible for maximum contact and reduced risk of partial contact.

I have attached some pics showing how the ferrules look like. Any scenarios where you need to connect small gauge wires then try to use a ferrule.

If you can add a heat shrink wrap to the connection even better for safety. cool

Get the MakeskyBlue MPPT Solar Charge Controller. That's the most basic.

If your budget is a little more rich, you can upgrade to Epever. Another Budget brand you search up on AliExpress, Konga or Jumia.

But beware of these Chinese clones. Your performance & quality may vary.

MPPT Charge controllers are like the gearbox of a car. No matter how powerful an engine is, it needs a transmission to get that power on the road so therefore in my opinion one should be try to get a decent brand to get the much needed power to recharge your batteries.
