The funny part of the story is that before the lightning issue, my wife called my attention to the space where the surge protector was installed before (that why is the place blank?) I just told her it’s possible installer just changed the position

That boy that came for maintenance is my prime suspect. You have to know how to bypass the connection to be able to successfully steal that thing without the users knowing. Trace when your wife asked you that question, if it was after the boy visited, go use slap and knock make the boy talk truth.

I am about to do this, please tag me when you get answers or decide to help us see how it panned out when you decide to do it.

Worst case scenario it'll enter error mode when voltage overshoots 450v.

You can only find out by a trial

Let me relay my personal experience. For the CC I use, 24v system accepts max Pv input of 100v so I used a PV of 105v. If the app breaker is turned off during high sunshine and turned back on the CC goes into an error mode. But if allowed to wake normally in the morning as the sun rises, it works well since the load on the CC keeps the input value sub 100v.

So that company is a scam? I just stumbled on this thread. His Instagram page is still functioning.

Hmmmm...

Nice one..

Although I think for this amount of storage, a lithium bank makes more sense. And that black flexible pipe spoilt your neatness.

Well done all the same.

Good job. But isn't the weight of those Gel SLA going to impact your range?

We are in Lagos. Here is one of our projects about to launch in Kano.

like maintenance and servicing?

The whole gamut.

jonescosmos:
10mm PV Cables for such a small unit? Honestly? Why do this?. You will loos energy bro.
The most practical wire for solar panels is PV1-F 750V-1000V Anti-Stretch Shielded Outdoor solar cable, this cable is most common in 4mm2 and 6mm2. A very rough rule of thumb is for arrays of less than 20A can use 4mm2, and 20A or larger should use 6mm2. If a larger size is required, it is recommended to run twice from the array to the solar controller.

Irrespective of the length?

When the big truck is coming, just clear it by the road side .
I doubt if there is any charging station in Nigeria. I'm sure people are working on that project and I'm also waiting to hear the cost and the materials used.
I guess people are charging their electric cars at home now using PV and NEPA light.
Pv is the best option

There is one at Adeola Odeku, VI Lagos.

Thanks for your contribution, guys. I sincerely appreciate.

So, i have opened up the inverter and discovered that one of the 4 output mosfets is burnt. First and second attached pictures show the damaged mosfet. The mosfet is S60N12R B (in third pic). I reached out to a technician in Arena about it, but he said that particular mosfet is scarce, that i could use mosfet Irf 740 (in fourth pic). He advised that, if i decide to use the Irf 740, i will have to change all 4 output mosfets as well so it doesnt spoil again.

Guys, please what do you advise? I do not exactly have the luxury of time to order for the mosfet from Aliexpress

How this Waka go?

The CD3301 ic got burnt and the mobo refuse to turn on, since this ic is kinda scarce, the best option is to bypass it.

Mobo turns on after bypassing.

What's the disadvantages of bypassing the chip?

Ehimzy:
Can you direct me to any competent engineer

Direct?? Lolll...person say 15k for what others are calling 200k and you mind no tell you say na to send am to am sharp.

Abi you think he doesn't want more jobs. 😂

dollarnaira:
The charging profile of the fan fits. The problem is the bms that will cut off at 12v is the issue here. Unless you act as the living bms i.e monitoring spirit . I am a living bms though.

You can easily build an LVD for that fan using a 555 timer IC. There is a circuit online where it is built like a controller, which I think you can adjust the turn on and turn off values to make it work as an LVD.

Hello experts, I'm considering getting a solar power system for my business, a cold drink store cos of poor power supply. Im more concern with powering 2 freezers (top priority, say 15hrs daily), and maybe 1 fan and 2 bulbs. I'm considering getting sunking (runs on lithium batteries) but the price is kinda outrageous about 4.5m (payment spread over 80 weeks and 3 years warranty), a technician said I can get setup (tubular batteries) that'll power the freezers for 7hrs on sunny days for 1m max. I'm lock between going for cheaper alternative and expensive and maybe a more guaranteed option.

What about less sunny days, what now happens?

Go for something that will last and deliver whether rain or shine. You can save some costs if you're handy with tools, by going the DIY route. Tons of valuable information available on the solar Fta thread.

If you are in Lagos, I can guide you to get the items and come install for you at a fee. I can do all of the procurement and installation too, but it's going to be more expensive for you.

But if you the sun king will provide the 15h run time you need, then I'll advise you to with that over the 7h guy.
