Okay, any drop in the lithium performance?.. i was thinking of upgrading to lithium soon. All the hype about lithium. Even mobile phones that use lithium battery, over the years the battery does depreciate. Phone wey dey last one full day after purchase, 6months later, e no go reach again..

Just providing you the companies you can use to ship things down from there...you don't really have to buy a single Growatt from US to ship down here. It may not be the most cost effective things to do.

My inverter was actually included in a big purchase from Signature solar and their warranty covers it.

It won't be cheaper to just source Chinese product from the US unless there's a deal to be had.

Sometimes I do buy things like phone, power tools,etc from the US, I use heroshe to ship it down or have a friend bring it down when they visit Nigeria, which is often.

My jinko 580w watts making me proud.
Rated 13.6amp at STC producing 13amps..

Hello Bro, I am trying to get in touch with you about your experience with the 16kw Deye inverter. Saw your post a while back on your not-so-good experience. I specifically need to buy a 16kw Deye and I am hoping to learn from your mistakes and hopefully buy a proper single 16kw, as that is exactly what I want. I don't want to parallel two 8kw. Is it possible to have your email for private communication?

kristien4:
i was getting 3900watts. I have 8pieces of 580w jinko panel. Thats 487watts per panel.

Due to my needs, I have added two other packs to the @ 5kwh pack to a total of @15kwh. Though I don't monitor daily or that frequently for that matter, I have not seen any unexpected behavior outside what is expected , based on the way I use them.
Nothing lasts forever, but one thing I never wish for is to go back to Lead acids. In Yoruba , it is called APADASIBURU (return to evil). If newer technology comes, I am very open. When I see videos of people lugging tubular batteries up and down, I tend to pity them and wonder why some people are still riding bicycles uphill when the direction to their destination is downhill.
If you have Lead acids now, by all means use them but please please my brother, there is absolutely nothing to gain by buying Lead acids in 2024.
I have used Sagem 4 sim phones before. Wonderful phone for 2005 but not for 2025. I hope you get my point.

What's the size of your battery bank?

kristien4:
4pieces 200ah AGM batteries...

kristien4:
Is 8pieces of 580w panel too much for 4pieces 200ah battery??

TechGeek777:


You may have to state the C Rating for your battery by looking at what's written on the body

TechGeek777:


Your battery is rated C10(i.e, you shouldn't discharge the battery in less than 10hrs)

200Ah/10 = 20Ah discharge current * norminal voltage(48v) ==> 960w(Don't discharge more than this at any given time).

80A is your Max Charging Current
80A * 48v = 3840w (Don't charge more than this)

Submission: Based on your Pv production of 3900w, your charging Wattage is good.

DON'T discharge more than 960w if you want your battery to see 3-5yrs!

Please are the new cells grade A? How can one tell the other other is grade B?

Sapiosexuality:
What could be responsible for an inverter reading 0 watts when the sun in early morning sun. I noticed these fluctuations yesterday. It moves from 1.5kw to 500 and even to 100w and less. What could be the problem?

HeavenlyBang:


Voltage may be below operating range?

Sapiosexuality:
This is the voltage and the charging has started and it just increased. Is there anything I can do to control or regulate it of make it operate fine?

Edit: I think I need time to understand this. I think I see it better now.

You can always buy from China and ship it direct to them. Sea shipping rate is not bad, just takes more time with ETA between 45 to 90 days.

Thanks boss. I appreciate the info. I wanted to ask, if i add 4 more batteries to make it 8pieces. That's 4s2p(400ah), can i increase the charging current too?

Nahum777:
Your responses have been helpful. What about custom fees and the like? I heard that's a huge problem. If I send $6k worth of Lithium Batteries, the custom dues would be crazy.

HeavenlyBang:


None of those pictures show PV input voltage.

First is AC output, second is battery voltage. It probably wasn't charging earlier because PV input voltage wasn't high enough.
