This SMK inverter is a shîtty inverter.

[size=8pt]Very shitty. Buyers' beware. A friend of mine got 2 of these inverters and they have both developed faults. One was repaired at cost. Stay away from them. And they are terrible for lithium. You can not program them.

Our installers please take necessary precautions while doing your job. Get gloves, wear appropriate booths, get harness to prevent falls, survey the area you intend to work to identify all potential dangers and avoid them. If possible avoid metal ladders, go for wooden ladders. God will not same us. As we are searching for what to eat, may we not run into what will eat us.

Drgreatone:
Pls bell my curiosity. For 2 colleagues installations, curious as to which would be more efficient. A 2kva12v hybrid inverter connected to a 12v200ah lithium battery and a 4.2kva24v hybrid inverter connected to a 24v100ah lithium battery. Both using 2 415watt jasolar panels. Would there be any difference also in the charging time and discharge rate assuming same loads? Thanks

24v100AH will be slightly better because of the greater efficiency of the higher voltage, lower current and lower power loss through heat. It will be slight. However the self-consumption of the inverters may eliminate or even reverse the differentials in efficiency.

I will only make comment on this issue once.

One thing I will tell you all is to pray against bad people that will disguise as friends in your life and drag you at the slightest opportunity. It's not everyone that's smiling at u that have good intentions towards u, when u r down their true intentions comes out.

This same person I have fixed his inverter for free, something that cost me over 70k (I spent that moni cos of padi padi) and he's claiming warranty on damaged MOSFETs.

I sent you cable twice yet you will say it's not complete. While going back and forth of it's complete and it's not complete, Next thing is you began threatening me on the fone and making foul statement like I can use 500k to fight for 50k, I will go on nairaland to go and ruin your reputation, I will arrange boiz to come and beat you. Who would have thought that someone I can close my eyes and spend 100k on if in distress without thinking twice will come and drag me that cable is not complete, such person will threaten to arrange boiz, such person will threaten to pull down my reputation.
You all better be careful with people that smile with you out there. They envy u in secret, one day their action will tell.
Calling me a thief and all sort of damaging things. He's saying them becos he knows I'm worth way more than all these things he's accusing me of.
Mr Reputation ruiner oya keep ruining.
I will also report this case to necessary authorities how you have threatened my life and peace. Should anything happen to me, they would hold you responsible.
You threatened anytime I come to benin you will arrange boiz to beat me up and all sort of things and also arrange for people to come and attack me in lagos. I will report all these things for posterity sake. Nothing must happen to me, you will be held responsible.

In all your responses, there is only one question I want an answer to. Did you send him shorter cable than he paid for? What did you do to address that problem?

Buyers' Beware.

It is a UPS, not an inverter.

It is 240V nominal voltage. That is 20 x12V batteries.

Charging current of about 4A is abysmally low. It might take 3 days or more of continuous NEPA to fully charge a depleted battery bank. Solar panel is almost mandatory.

Peter Obi has strongly denied accusations that Rufai Oseni supports him because he sponsored the burial of Rufai's late dad.

He said,

Source: Peter Obi

So, where in this lengthy "denial" did Peter Obi categorically say that he did not give Rufai money for his father's burial?

You have good intentions, but you are giving Puvo a dangerous advice. Over 90% of batteries in the market these days are fake. He is better off buying based on recommendation over there in his State or buy from a trusted seller/dealer here in Lagos and have it waybilled to him, than buying a fake battery and having to get it replaced after 6 - 9months.

I will suggest to buy battery locally as much as practicable. For people living in Uyo, it is easier to return failed battery to supplier in Uyo than in Lagos.

If 520ah is roughly equal to 80% then your battery bank capacity is less than 1000Wh. How does it compare to 12 units of 12v/200ah ~= 29KWh bank though?

I have no idea how you are calculating your figures but 520AH at 48V is about 25KWh.

Nice one... but check the bolded again. A typical 30L water heater takes about 15 to 20 minutes to reach the setpoint.

I don't know what boiler you have, but mine takes longer. Maybe it has something to do with the length of the piping involved and concurrent use. The heater supplies 3 rooms and serves 4 people on most mornings with children and wify sometimes letting the hot water run off because they are multitasking.

Bragging Time

The last few days have been very cloudy and raining in Ibadan. So, my solar yield has been poor.

This morning I discovered that I have taken 520AH from my lithium battery bank which is about 80% of my total.

I sat down to do the calculation. 520AH at 48V is like draining 12 200AH 12V lead acid batteries to zero. However, given a 50% DoD, already above what is recommended for Lead Acid batteries, I would have needed a bank of 24 200AH 12v batteries.

And even then my system would have shut down because my pumping machine drawing about 2KW and my water heater drawing about 1.5KW still came on at 4:00AM and 5:00AM respectively. Pump for 25 minutes and heater for 90 minutes. Voltage would have gone down low enough to trip the inverter.

If you are not using lithium batteries, you can not appreciate its resilience.

when victron energy, morning star, outback, fangpusun, sneider MPPT charge controllers dey, wetin u wan do with one yamayama Felicity. Felicity is a low budget MPPT cc mehn.

Felicity Charge Controller is not bad, and I have used Outback, Midnite Solar and Fangpusun Blue solar in the past. I exchanged my last Midnite Solar for a Felicity and my last Outback FM80 is doing 12V duty in my office since it appears as if its input capacitor has become too weak for my 48V system at home. I currently have 2 Felicity CC 120A and they are both serving admirably.

Hello, that you've a soft copy of a particular company pricelist doesn't give you audacity to paste such on a public fora!

Isn't this act rather EXTREME and unethical?

What is extreme and unethical is inflating and hiding your profit margin on an enthusiast forum. This place is not a showroom for your goods, it is an open forum where enthusiasts discuss solar power and assist each other in the solar journey. If anyone has the factory price of any good, they should be free to post it. It will help us when we negotiate with vendors as we will know that the "I'm selling with only 2k margin" is a bloody lie.

olopan:
With your 10KVA Growatt inverter there is almost zero chance of upgrade as it may have appear you may have exceeded your configuration due to your much PV (27 Pcs).

It is best you get an external charge controller or change all your panels to bigger wattage and a simple design this time around in two set wrt the two MPPTs

You can mix the lithium batteries. The BMS makes each battery behave like individual cells and allow them to go at the pace appropriate for them.

Boss are you sure of this?

If he should add two more panels as suggested (making it 2140w), can his 60a CC produce more than 800w for his 12v system?

You are absolutely correct, I didn't think about his voltage. I use 48V and my thoughts were wired along that line. I think he should consider a 24 or 48V inverter. 12V inverter will be problematic in the long run.

Good evening house, please I want to set up a frozen food shop for my wife. So I want to set up a 2kw solar system for her. She will be running only 2 inverter freezers 100w each for maybe 9am to 6pm. The set up will be done in the house and we will extend the wire to the shop in front of the house (Like 60yards distance).

Here are the things I planned for, hope I am on the right track?

1. 535w jinko panel (2)

2. 2ka inverter (don't know which to buy yet) please if you have any suggestions.

3. 60a mppt charge controller

4. 12v 160ah Lifepo4 battery

5. 60yards 10mm² cables

6. AC Spd 275v tomzn and Dc Spd 500v tomzn

Only the two freezers are going to be used. Please, am I on track with the above? If not please advise me anywhere you feel is not okay

I will suggest you add 2 more panels to ensure that both your freezers and the battery are adequately served during the day. The rest are okay as long as your wife doesn't become the centre for everyone to come and charge their phones and rechargeable lamps.

Finally did the test today with "CLAMP METER DT3266F"
Surge: 16.64amp * 230v = 3,827.2w
Continues draw: 8.2amp * 230 = 1,886w

The reduction in consumption is as a result of stronger/better wire used (2.5mm² Comester)

Below is the initial test done in Q1 of this year.
Max Surge = 19amp * 230v = 4,370w
Continues draw = 11amp * 230v = 2,530w

Can you post the picture of the new wire? Thanks.
