1.25m now an entry level and a budget set up for a 12v. Evidence of bad economy laced with inflation. Omo 12v set up now a luxury and unaffordable. How did we get here?

1. This 12v pure sine wave inverter has the capacity to power 4 freezers @ the same time.

Capacity: 6000w Surge capacity and 2750w Actual capacity

Dc to Ac conversion efficiency : 90 - 95%
Idle consumption : 0.3 amp

It is a Non-grid tied Inverter. It powers Inductive and non-inductive loads seamlessly.

In the test video below, I used it to power all these appliances @ the same time:

👉 One normal freezer
👉 1hp pumping machine
👉charge spare battery
👉 one 32inch TV with Decoder
👉 2 medium sized fans
👉1 big ox fan

Then I switched off only the pumping machine to plug in the 1200w pressing iron


I have just one left, If you are interested in buying it, call or WhatsApp 08035537864

2. 12v 30A Smart Battery charger with digital display

It can be used to charge any type of Battery and it does not overcharge batteries, it is a smart battery charger, it adjusts itself to the amount of charge battery needs and stops charging once battery is full....

Uploaded below is the Smart charger picture.
Call or WhatsApp 08035537864 if you need it.

The MC4s are crimped and connected correctly.

I did some testing and discovered that only the negative of the 2 MPPTs are connected in parallel, while the positives are independent of each other.

I'll have to disconnect one of the panels pending when I resolve the issue.

jonescosmos:
Then it's possible that your MC4 connectors crimping is wrong. Before looking inside the inverter,
Make sure that the Negative Cable coming from your PV (after leaving your breakers and spd box, if any) is crimped with a Negative MC4 connector which will plug in to the Positive MC4 connector (PV-) on the body of your Inverter like wise the Positive PV Cable is crimped with a Positive MC4 connector that will then plug into the Negative MC4 connector (PV+) on the body of your Inverter.

Everything should work well after making this correction.

Good day people, I intend to install a 5/6kva hybrid inverter. I have attached the quotation received from my installer. Just wanted to get remark about the adequacy and reasonableness of this quotation from knowledgeable folks and experts in the house. I welcome any advice, suggestions, comments.
Is it advisable to combine a particular brand of inverter (eg GOspower) with a totally different brand of lithium battery (MARSTEK)? While my installer quoted 1.7M for the battery, I did some research and found the contact of the main dealer of the battery in Nigeria. I could get it for 1.2M directly from their office in Ogba. However, the hybrid inverter of the same brand (MARSTEK) cost 1.2M and they're not willing to reduce the price. They advise buying their inverter and battery together but completely optional with a caveat though - that combining my battery with a different brand of the inverter voids my warranty (10 years), as they cannot vouch for the performance of the inverter I would use if it's not from them or one of brands they've tested. They sent me a list of other brands that their battery is compatible with, however, the prices are ridiculously high compared to theirs.

Is it worth taking the risk to go ahead with the quotation given to me by my installer? I don't just think I want to buy an inverter of over 1.2M. It's a lot mehn.

The company will give you 10 years warranty if you buy the 5kwh lithium battery and the inverter together, right?
Does it mean there will be no warranty at all if you decide to buy only the inverter?
An average warranty most companies give to inverter is 2 years. If that company accept to give 10 years warranty for ithe nverter and the battery, then I'm assuming that the battery warranty might be 7-8 years.
Then note that any lifepo4 battery manufacturer that gives you 5 years warranty and above on its battery MUST be batched and matched grade A cells used in coupling the pack and it will NEVER be in the price range you' have mentioned.
Maximum warranty they give in quality grade B cells coupling battery pack is 3 years.
You can drop the datasheet of the lithium battery and let's see the information.

Good morning all,my friend that went to china he sent picture of this battery,if he s should buy it

What actually do you want to find out?
We only see the picture of the package and we don't know the quality of cells inside.
You may furnish us with the details of the battery pack and let's work on it.

Most reason most of us that started this journey a few years ago should take good care of our investment and thank God for the foresight.
Most family can't even afford fresh tomatoes now in the market,

It's getting worse by the day...........

I think deye does this too, 10 years if the inverter and battery are from them.

Just pulling ur legs boss. You are doing well sir.
In the end, doing what's best for ur clients is what set one apart as a good installer

ok let me ask him,my guy said he has bought the battery already,they gave him guarantee

Kindly clarify this statement, is it inside the inverter, done by deye herself or installer done?
Why not connect the jinko panals only and observe the inverter, since you have connected the other string without issue.

Is the multimeter still available

Dear All,

Got a quotation from another installer, just for comparison sake.
Is the second quotation not an overkill. I thought I'd be making some savings from a partial DIY then the second installer came with this?
Experts in the house, what do you think about this?

Accessories and mounting are not cheap, If you are in Lagos, I can help you lower the cost.

Inflated quote.

I get confused when we rate panel purchase with ba3 size.
I use to think it's getting a solar array that can easily replace power consumed daily by the user. I come learn oh.

HeavenlyBang:


See many load wey he get na

Anyway, I'd say a 10kwh battery should be just about enough. Maybe 15kwh if finances allow, though he'd probably need to increase his pv array to around 6kw.

Oshomo12:

I told him the Jinko is the issue. That it's Isc might be exceeding the 17A during sweep on favourable conditions. He said it hasn't exceeded 12.5A before (refering to Imp).

Please post the side sticker of your Inverter, or send the specific datasheet or model of your inverter.

From the pictures you attached your model is either SUN-3.6KSG03LP1-EU, SUN-5KSG03LP1-EU or SUN-6KSG03LP1-EU

If yes, then bolded is a confirmation that your inverter has just 2 MPPT with 1 string each and both trackers should be independent with a Max ISc of 17A each.

I hope one of your PVs is not shorted or leaking power to the frame.

Please take a look at the attached Datasheet.

For OFF Grid system.
Sizing panel is to cater for daily usage, day time plus Night time..

Forexample if your load consume 15WKH, Using 3hours you need 5kw panels minimum too serve on average days. If sun is not enough you ration the load. But you can always oversize as budge permits, you will waste power on good days and enjoy it during bad weather conditions.

Now you size your batteries based on usage pattern, when do you use most power during the day, or night? What is your ideal night usage, some use more power in the night or at specific time?So Night start at 4pm and ends at 9am. So how much energy do you consume during this window will determine your Batteries capacity, let say you use 8kwh(DC usage) during this window, then size the batteries to 10kwh or more as budget permits. The solar panel will power the load connected during the day and also charge batteries for night backup.
