3. this means you need to start from the batteries, as Marstek promised to send down a technician, then wait for them.

4. Also contact the installer to explain how the panel was configured.

Thank you

Dam5reey:


How was the Panel connected?
Panel Brand and specs?
Do the Batteries have Monitoring showing SOC, Voltage?
and did you Install it by yourself?

1. Honestly I have no idea.
2. Sunshine solar panel
3. The battery has 6 LED lights to indicate SOC (see picture) according to the manual but since I got it, all the lights have stayed on even when I'm using the battery to power the load. all the lights just stay on which is quite weird. I suspect that probably because the BMS has not been configured, so the lights are not able to show the state of charge correctly. So I have been relying on the inverter panel to read the battery voltage.
4. I used an installer.

What was battery percentage at the time? How much load did you have on?

Next time when you have full sun, put on some heavy equipment (microwave, heater, etc) and see how much power your panels pull in.

The load fluctuates between 336 - 400W

Hello Guys,
I just installed a 6kva inverter system. The inverter brand is Gospower (6kva) while the battery brand is Marstek (5120Wh). This combination was recommended to me by someone. It's been up to 3 weeks since I installed this system and I am not yet impressed. The first issue I have observed is that I hardly get up to half of the total power output of the solar panels (10 x 330W). I understand it's cloudy but the few times the sun has shone bright, the maximum output is usually around 400-500W.

Second issue: I observed an anomaly yesterday when power went off. I observed that the voltage on the inverter panel dropped drastically to 48V from like 54-55V upon disconnecting from the power grid. This was shocking to me. Then shortly after that like 5 mins, the voltage dropped further to 47V which triggered the inverter to shut down. I had set a low DC voltage of 47V. My load consumption is very small - ranges from 200W to 400W. 400W during the day when the industrial fan is on. All other appliances are basic.

My next course of action was reaching out to someone to come do an independent troubleshooting and inspection as I can't tell where the fault is coming from: inverter, battery or the installation. Secondly, I contacted the battery manufacturer to complain about the issue and they promised to send a technician over.

I'm still in shock as regards what might have caused this issue.

First Pic was taken shortly after power went off showing the drastic drop in voltage.
Second pick was taken upon restoration of power in about 10 mins when it first went off. As you can see, the battery charge status shows a fully charged battery and voltage rose back to somewhere between the float and bulk voltage.

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

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.

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?

HeavenlyBang:


Buy battery from Felicity or Sako.

Or buy from Valto or Isangjohnson. Best wh/# on the market rn.

Use the money you saved from the battery to buy more panels. 1800w is nice but in six months you'll be wishing you bought more panels, trust me.

Thank you . What's the downside of installing 1800W in 6 month? Not an expert but asking out of curiosity

Dam5reey:


Alright, just as posted earlier today you can go for the setup below:
Almost Double the Panel Size for the same amount: 5KW Inverter, 5KWH Batteries and 3,330W Panels

LFP batteries at least 5KWH 48V for a start, 1.2M Marstek you already source.
Hybrid inverter SAKO/WELION 5KW 48V with MPPT at 500K max.
Solar Panels 6 units of Jinko 555watts, 960K
Accessories and installation about 440k
To make 3.1M total

Much appreciated

Dam5reey:


Your installer is on point, he is taking full responsibility for sourcing and warranty claims, that is not an easy task.. do it yourself to gain experience anyway!

Since you are a Semi DIY, Buy the inverter and batteries from them, but you are on your own you will have to liaise with Marstek if anything goes wrong.

And let the installer do his installation job if he is still willing to.

You can combine inverters and batteries of any brand with no issue, A batteries Manufacturer should not use that as an excuse to void the warranty is a bad sign. You should be fine if you maintain their recommended charge and Discharge profile.

they should have gone ahead to tell you that your load also may void your warranty

Thank you for your comments. You're right about the installer taking the warranty up in case anything happens but that doesn't justify unnecessary mark up in the price. Increase in the price, fair enough but let it be reasonable. Honestly, money is not easy to come by these days. It's hard to cough out this much and I'm sure you understand. I want to optimize where I can and where possible and feasible with sacrificing quality. I am open to a win-win option that works fine for myself and the installer but he doesn't want to bulge on the prices, hence, the need to procure the materials myself.

Today I saw a fake Jinko panel. The junction box cover has an embossed Jinko boldly on it. It's 250W and VoC is 60V. Lol


People will buy it as Jinko and start wondering why the panel is underperforming.

Meanwhile Jinko has discontinued production of 250Wp solar panels, and when it's in production VoC was 37.7V

Hello, please do you have a plug for original canada solar panel?

Wish I can partner with someone to buy this? What other facilities are available? How does one get water?

Hi everyone,

I am looking to rent a poultry farm in Lagos by October or November this year. Budget is 1 million Naira per annum. Please contact me by responding to this post if you are renting out a poultry farm.

Are you open to partnership? I'd be willing to partner with you should you find a poultry farm to rent and are open to partnership arrangement

Dear All,

Good morning. I am seek equity business partnership with interested persons. Please note that this is not a crowdfunding opportunity but an invitation to become part of the business (collective ownership and sense of responsibility) and contribute to the progress of the business. I am willing to give up 10% - 20% stake.

Interested persons should send me an email to Nutridelfarm@yahoo.com. I will be setting up a video zoom meeting with interested persons where each person would have the opportunity to ask questions, know more about me and the business. Also, I will be presenting an investment pitch pack.

Peradventure, you have doubts or see this as another packaged scam or will react negatively to this post, I take no offense and I totally understand as someone who has been had his fingers severely burnt in the course of investing into agritech crowdfuning. I understand! I will simply move on and continue to deplete my savings and earning to fund the expansion plans as I am currently doing. However, this is an opportunity I'd like to view with an open mind.

Attached to this post are:
1. Process Flow Diagram
2. Picture of our ongoing mini poultry processing plant which commenced last week Monday. As you'd see, significant progress has been made within just a week.

Thank you for your consideration. I am available to answer any questions

Still up
