But this numbers here will lead to tears.
No be all meat person dey chop.

I understand d angle u looking at it from bro, but my take is that d project is doable provided the installer/engineer prioritise quality components and a top-notch installation and then go into details with the client, letting him to know that energy generation might drop during d raining season but a good value for money during the dry season.

Are you looking to Buy brand new or Used ?
The Used I know of is 40amps while the brand new I know of is not directly under my care. Also you're in Anambra while I'm in Lagos

Is the 40A capable of charging a 48V system? The SRNE 40A chargers I know are unable to charge a 48v system; they max out at 24V?
How much is the person with the new one selling (for 48V system)?
Almost all goods come from Lagos, so distance shouldn't be a problem.

Used is fine, if it is for 48V battery.

A user-defined option, in most cases is equivalent to the Lithium setting.

But then again, depending on how far you can modify those settings, you just might be better off getting a Charge Controller with support for Lithium batteries. This is mostly because the charging pattern for lead acid batteries differs from how Lithium batteries are charged e.g Lithium doesn't require floating.

In fact, except you just want to take your chance, would just suggest you get another charge controller with Lithium battery support. Even if you use the User-Option, you still wouldn't be able to completely replicate the exact charging profile for Lithium batteries which mostly have just 2 stages compared to the 4 stages of lead acid batteries.

Thank you so much for taking the time to respond. I truly appreciate your guidance, and I’ll definitely go for the one with the lithium settings.

Client wey insist on buying everything himself, have had to change his MUST charge controller in less than 8-months. Money wey him no want take buy quality item, him don spend am the other way round.

e get the kind capacity you go dey run, you need quality items. At least play your part make you know say you don try.


Another thing is, Solar power isn't really all that super efficient on some load types. e get as the load go take big reach, petrol / diesel generator go just better EXCEPT they really got the resources to plan and build such system. At such stage, that kind work no be wetin dem dey give any how

u can literally get away with panels and inverter.. d real koko na battery backup. if na me de this shoe.. na to let client know say na continuous upgrade till de become self sufficient... esp on battery.....make una draft out plan.. a 100kwh battery

brightk:
i would rather pick a deye 12kw over growatt 12000 Es. but factor in their pockets..

As you sef typed this Deye 12kw, your heart no cut small for me?
No be yahoo boy get the facility 😭😭

reason with the client.... this setup will cost a lot... like i said its easier to get inverters and panels.. if money b d problem make una start small... not all loads will be on the inverter for now.... u can do 6kw*2 or 8kw x2..... and enough panels as u can afford. Start with 1 or 2 battery packs.. let him know its a continuous project.. if he is really serious.. he can be self sufficient in 2yrs.. draw out a comprehensive plan and spread it such that in 2yrs he can be able to do 70% of it if not 80%.. u can make comparison btw deye, growatt, alpsolar and solis... try and choose an inverter with large mppt power... like i said go to the location, do your own analysis and draw out your plan. if e nor reason with u my broda make u clear fast fast

issue be say, most times, this kinda work no be direct hence at end of the day, they spend huge but a lot ain't on the project it's self and the middle people would prioritize GAINs over quality hence if you quote any how, they get you replaced the moment they're unable to get a lower quote (which they would later inflate) from you.

They make the GAINs, while you bear the burden

This 40amps in particular doesn't.

The problem is that hospitals don't know seasons-- patients can't be predicted and number of appliances cannot be rationed especially during emergencies. Personally, this project is not feasible(my opinion though).

Do you have any 48V charge controller that has good communication (RS485) e.g. SRNE or DEYE clones?

if brand new, can always get from where I buy from. As for used, it's based on availability.

Someone in here has got epEver 60amps though I don't know if it supports Lithium battery. Most old version epEvers don't have such support except the newer versions.

As for the RS485, most of them have got it. Hopefully the person who's got epEver in here can signify. Make I never mention name since e dey online already

Bottom line is, if you need NEW, I could help you arrange that BUT for Used, I would have to source for it.

ask4bk:
Are there non-hybrid HF inverter? Or you meant to write Low frequency inverter?

It'll amaze me to know there's a non-hybrid high freq inverter. Pls what brand is that?

Yes HF inverter..
There are several types in the market.
There are PSW and MSW.
You can check out for brands like Easun, Talakalata ( not sure of the spelling), sutu etc

If I were to be d engineer, I would suggest to the hospital management that we should split the system into 2 groups, 5kwHF inverter to cater for the fan, computer and bulbs and massively overpanel the set up since most operations would be during the day n lesser activities at night n with 20-25kwh battery should be fine while the 2nd installation that would cater for scan, fridge and lab would be a 6kw transformer-based inverter cos of the huge surge and moderately oversize the panel too, the battery size would depend on whether fridges, scanning machine n lab activities would run 24/7 or just during the day only

Lmao, probably the most impressive battery you've tested. Funny that some people were bad mouthing it here a while ago.

Hello guys , does anyone have this mini 1600w pure sine wave inverter

Good evening y’all
Please I need opinion about this inverter, I know it’s a non hybrid but I’d like to know if it make sense to buy or it’s a no go area.
And also any idea about its idle power consumption and repairability?

People need to be wary of these reviews. It is important to know how the "samples" were sourced. The reviewers also need to declare any conflicts of interest like free samples, paid reviews and commercial partnership with marketers and companies.

Even big companies like Samsung have been known to game the review systems by supplying reviewers with "supercharged" samples. For example, I think Samsung once had a hidden code that detects benchmarking software and then ramp up CPU and GPU to achieve scores that are not achievable in normal use.

It is not impossible for battery makers/marketers to supply top-grade batteries for reviewers and park their commercial stocks with low performing components.

The best REVIEWS are what users on the field say about the batteries and other components.

Pretty weird thing to say without having as much as a hint of that actually being the case. Almost reads like an accusation.

Could you be right? Yes. But asking people to be wary simply because of a broad possibility doesn't sit right with me.

I do agree that Dam5reey1 should state if review units are provided by OEM, though.
