please go ahead….The highest current you can get from 400w panel during peak sun is 20a on parallel connections and 10a on series assuming you operate on a 12v system,just make sure to use better DC cable you will be absolutely fine….

yes I'm using a 12v system.. so if I truly i get 20ah on a peak sun it's fast charge enough for a 1.2kw(100ah) battery with Bsc pwm controller, while am using a 4mm dc cable for the panel

AyarmBoye:
I believe your system is small enough,,I don’t think it’s necessary,,just have good and proper rating surge protectors for both AC and DC…

surge protectors how, the 12v system is connected to change over where generator is.. Nepa & inverter to change over.. the only protection am looking out for is using a 63a Dc breaker in between the panel(pv) wire and controller input

I believe you should have a separate change over switch for the inverter unless you don’t ever wana use generator…Anyways 63a breaker for 20A current is an oversize..It won’t help when there’s spike sha…I think 30a is the best depending on your panels spec…63a is just an oversize which will only serve as switch…it won’t protect sh**t

note that the 20a current I estimated is based on Mppt cc…I doubt pwm can give you…you will be lucky to even get 12amps sef….

chaii.. that sucks.. I'm using a pwm cc jare, that means on raining season it won't charge at all

I'm not ever using generator.. what's the essence while still keeping generator. However I made a mistake it's a 32a dc breaker i meant to say. The vendor is telling me 13k last.. the pic below is just a 63a.. a sample of what he's giving me. . He said the 32a is far away hence can't scatter things to snap and share to me

Bryanluke:
do i still need to earth my 2pcs of 200w panel for person house. I need to do earthing again

Earthing is NOT a must especially for really small setUps EXCEPT you don't mind spending. For such small system, just invest in good rated breakers both for solar panel, battery, AC output, and optionally AC input (only if using NEPA / Generator with ya inverter)

32a is fine….13k for it is not bad..Ali express sells for that range and u wait 2 weeks to reach Nigeria

like @AyarmBoye said. He stated 32a dc breaker is a good one for the panel. And I'm not using gen so I fixed it to change over.. I'm using those designed 18650 lithium ion battery of 1.2kwh(100ah)..

Bryanluke:

pwm will whine you…Best to use pwm is when your panel voltage is very close to your system..eg 18v panel for 12v system,,,30v for 24v system…but high voltage panels will bee wasted under pwm….during. Cloudy days ur panels will barely give 5amps

AyarmBoye:

na with abeg, he stated 15k before..
So with that 32a it'll cut off immediately there's heavy voltage from thunder strikes on the panel

yes I'm only using a 18v, 200w panel since it's Pwm & a 12v battery system alongside with my 1000w or upgrade to 2000w sachet inverter so I can use ceiling fan with on sunny days in the afternoon if am home. But my family and am not always home till night

but if there's cloudy days will i still get like 4ah. I've contacted the installer you're right. He said 2pcs of 200w panel is 9ah with his experience installing so far

you should get 3-4amps but mehn your battery will suffer unless you don’t pass 50% DOD

AyarmBoye:

battery suffer as how.. so make i no dey use the battery to drain off on raining or cloudy days so it'll charge up faster the next day

yea..You will understand when u start using only solar to charge…unless ofcourse you wana use grid to charge.

hmm.. pls educate me, cux I wanna go off grid with this setup ni

Done over the weekend!

Location ikoyi

10kva srne inverter

32kwh deriy lithium battery

Off grid with this setup?

Bryanluke:

I was offgrid during the dry season with my 2 535w panels and 4kw battery. But this season, I am on grid ó. My ac in breaker that used to be permanently off is now on.

Well done, but I can’t see any SPD in this your installation and you didn’t use bus bar box to combine the two high capacity batteries. No heat aerosol or fireball extinguisher installed. By the way, it’s just my personal observations.

Do you really need a battery busbar for two batteries?

it actually depends on your principles as an installer.. i will attach a fuse on each battery and wire them up to a busbar

Thank you chief for your observation


This is just inverter and battery installations only.. I don't use busbar for two batteries installations I just paralled them with the same cable length.. all good... I have installed both AC in and AC out breakers installed . thank you for your observation..

brightk:

The battery has an input breaker anyway

we learn everyday.. shud there b an issue, can those cables withstand a large amount of current than they are rated for? those breakers cant help in catastrophic events..

Penuelseun:
They are not compatible as the input current of the 620w solar panel is higher than what the inverter can take

Thanks for this.
How about using 4.2kva inverter whose max input current is about 18A with the 620w panel? My battery storage capacity is 3kwh.

Atimes, some of us forget we ain't PAID to teach you how to take away our JOBs.

I presume this conversation been long enough some of us must have forgotten the initial conversations and not everyOne would have such time to start checking previous pages for such FREE work

So would suggest you share with us a clear picture of the sticker on your hybrid inverter and then tell us the wattage and quantity of the solar panels you looking to use. That way, we could be of help without getting unnecessarily workedUp.

Just in case you might not have observed, atimes people don't respond because they don't have the full details and don't have the strength + motivation to start worrying themselves.

I can understand you now boss but it’s still better to install an AC SPD and Voltage Regulator to safeguard the setup.

Happy Sunday, everyone.

Does anyone know this brand of induction cooker?

A vendor initially sent me what was supposed to be an induction cooker, but when I switched it on, I discovered it was actually an infrared cooker. I had to send it back, and they sent me this one as a replacement.

I've tried it, and it seems quite good. However, I've never heard of this brand before.

so long it performs and you are given a reasonable warranty,then it is all good, I actually like the it is double stove top. Please how much is it
