@BigRovar. Yourself and GeorgeD1 have stoutly defended the reputation of your Su-Kams - in my own experience I rank them as 'okay' inverters - they don't excel in charging amps capacity and they lack ability to select different voltage algorithms for different battery types, I wouldn't confidently load them over 70% their rated capacity and everyone I know has visited service center at least once in a 5 year period.

What is the final verdict? Are there some techniques or practices you follow to derive such good value from your Su-Kam inverters? Do you have some extra protections or limits set on your systems or add-on devices to supplement the base performance?

brother,
in the hierarchy of inverters sukam can be classified as mid-range and not to be
confused with high-end models like schneider (formerly xantrex), magnum, outback, sunny boy, etc.
however what stands it out is it's surprisingly low idle power consumption and the quality of its
sine wave output as well as its ruggedness. if visiting service centers within 5yrs of use is to
be used as a valid rating criteria then I think almost all inverters would score low on that point.
take my magnum for instance, the fans failed within two yrs of use and I had to send it for
repairs - which was done free of charge by the way. does that make magnum any less rugged?
I think the answer is no.

As Oga george noted, Sukam are mid range and has lots of limitations as you have highlighted. But it is not has bad as many claim on here. Sukam was designed for the Indian market. It was designed to be simple and easy to operate. It was designed to work with batteries that are most popular in India mainly tubular and SMF batteries often manufactured in India. The reason for the low charge rate is that, due to a better power situation in India most people use one battery string with their inverter hence inverters are designed to charge the battery at about 15% of C20 which strikes a balance when charging flooded and agm. For the Indian environment with its less frequent power failures the inverter works perfect.

Lastly very few inverters (not even high end)have the ability to do transfer from grid to inverter in less than 8 milliseconds allowing it to be used in powering computers and network applications without any hiccups.

- if your CC breaks, I will give you a spare I have on hand for free but if it works you will owe me a round of drinks in addition to the 100k you already owe JUO

The limit you must never cross is the PV voltage limit like Pranil said - crossing that you will definitely brick the CC.

All these caveats are apart from the power loss/wasted power with unnecessarily oversized arrays.

Lol, thanks bro for the offer, i appreciate, though truth be told, the funds to get the additional 500w panel isnt available at the moment.
my short term plan now is to turn off the fridge for 2 to 3 days, every wk....till the weather improves or the funds and time to go do the upgrade becomes available.

like i said earlier it s a rudimentary setup for my folks in the villa, nothing fancy

PRAG 48 - V ( grren color) 5 KW inverter user manual

Need user manual or at least battery charging Voltage selection page /table urgently where the pot positions explained.

I am replacing the office batteries and cannot find the manual anywhere !

Prag seems to have stopped supplying this inverter and replaced with a Hybrid MPPT

Dear marketer

1. You have ideal product but do you have referrals who can vouch for a clean deal?

2. Consider reducing ur price.

Just my piece.

I second the motion, Comrade Efuro.
Price reduction is the righteous thing to do in this economy.

Efuro,

always on point on cost and especially the opportunity costs.
I norminate you for the forum finance minister

Hi Solar Enthusiasts,

Please has any one used PSC Solar Industries panels?

Are they worth buying given it's quite pricey?

What are your experience whether directly or not with the quality of their panels compared to other brands?

Is the bold claim of "Made in UK" real?

Thanks.

Well, I have been using the Gorilla fans (2) which I bought from the supplier for a few months now. The benefits so far are:
1. Very low energy which is great for my inverter. In the past, I had to selectively use my ceiling fan on my inverter but now that's no more a problem.
2. Remote control means I can be as lazy as possible and I can change fan speed in the middle of the night without having to get out of bed.

In summary, it has been a great experience so far.

Takw the made in UK with a pinch of salt. Same guy behind the company claimed he invented the company's PSC inventers after years of research. Even got a news paper to carry his story when infact the "made in Germany" inverter is nothing but a rebranded powerstar w7 inverter like MUST, Prag and Felicity. Even the manual is same with powerstar word for word. I can't attest to the quality of his solar panels but they are mostly a rebrand of a Chinese Tier 2 producer.

opeoluwat,
what happens when the remote gets lost or damaged? don't you think a regulator would
have been more handy as a back up?

it may likely hv a normal push button remote too, like the qasa fans am using, hv remote with timer.
the receiver for the remote is embedded in the normal wall control
the qasa has a 70w sticker, hvnt tested them to confirm........am pleased with them, cost just 8k and the remotes work with any other fan model. so one can buy them and use the remotes for the rechargeable ceiling fans

Thanks all for your comments.
To answer if the remote control gets lost
I use a light switch to power it on and off in addition to the remote control and I advice others to also. There is also a function built into the fan where by toggling the switch you can change the speed. If one loses his and needs another I can order for a replacement remote for the person.
With regards the price no doubt it is expensive but if compared to LED bulbs which are 5 times more expensive than incandescent bulbs it isn't that expensive. Being a new product it is still expensive but as it begins to scale( large volume manufacturing and importing) it will begin to reduce in price. I believe it is a good product though expensive it is worth the price.
As for opportunity cost � The cost of designing a system with 4 regular ceiling fans and 4 gorilla ceiling fans are not the same in battery cost, and even in the cycle life of the batteries over time.
Please contact if interested in buying. Thanks all have a wonderful week ahead.

GeorgeD1:


actually the answer is yes. i have a sukam 3.5kva fusion series and
no problem at all with equalization voltages from my tristar cc. others
may have a different model but mine is not exactly a recent brand so
it's hard to see how more recent versions should have this problem.

so, what is the different between su kam inverter & expensive magnum inverter which you're using?

Please has anyone used Yingli mono solar panel in the house? how is it?

I've not used it but have my doubts about genuine Yingli panel availability in Nigeria.

I recently considered it but on further investigation I realised what is been sold in Nigeria is of questionable quality not genuine Yingli.

Even the datasheet document appears to be fake when compared to the original.

My conclusion is double check any panel been sold to you because there more substandard panels in Nigeria than genuine ones

What is the source of the Yingli panels being sold in Nigeria that you heard is substandard ? I am aware that Yingli have a sales outlet at Opebi and Alaba. I wonder if such outlets could be selling fake Yingli panels. I bought two panels from them and they are working just fine.

The true Yingli panels work like a charm. I have a few and I can attest to the fact that they currently outperform my other JoySolar (mono and poly) and a few other brands at the moment. It's true you might be hard pressed to find quality ones right now. Likely you'd meet rebranded panels with the Yingli tag. There are a few out there though. Few people stock them (marginally pricey for a Chinese brand).

I know a such a guy, should you need directions.

Yes you are on point ! Yachi 310w mono panels will be available by month end incase he needs good quality Chinese panel

Please make the contacts of this guy who deals in genuine Yingli panels public on this forum

We need to encourage patronage of such dealers no matter how marginally pricey.

Lest people loose faith in RE and waste hard earned funds to dubious dealers.

If you intend to Go totally off Grid, then your Panels is not enough to generate 1090w for 10hours which is approximately 10KWH

Point of correction, we do not have 8 hours of full sunhours.. you will get 25% to 75% from 8am to 11am and 2pm till 6pm and 75% to 100% from 11am to 2PM.. that means you have 3-5 hours of sun on a good day..

In order to generate 10KWH you need 3-4KWH solar array..

Also you need an MPPT controller.. Not PWM.. for maximum harvest..

I'm afraid your 800W solar panel can only produce about 3.2KWH on a good sunny day...

He might be scared of lower price tags, They Dropped their prices of recent, Also they just introduced Mono panels,
The panel they used to have in stock about 2 years back are Poly..
The poly I bought from them are performing very well..

Sometimes buying PV modules are subjective decision.
We know fast buoys are capable of rebranding best brands.
If he want a reliable PV let him try sunshine solar module. He can thank me when he isolate & test them before incorporating it to upgrading during installation.

I had mixed feelings when I ordered for some( particularly when people believed it is of a lower quality) surprisingly, i had a huge leap in my production almost up to nominal PV ratings. I have since been harvesting my returns immediately. I observed the design of each cells has been changed from previous design thay had.
With that experience, I have since received my fresh order, installed, enjoying my investment.

Depsite bad weather (as if the sun always draw clouds to cover its face) I consistently complete my 2hrs bsorption by 10.30-11am with my 3x4 setup. And always looking for what switch or put-on to keep my modules smiling.

I am not advertising sunshine modules. As DIY I will say the reverse if it is not true, after all it is my investment and my setup.
