3. this means you need to start from the batteries, as Marstek promised to send down a technician, then wait for them.

4. Also the installer to explain how the was configured.

Thank you

She said 2 to 3 months. That means early March to April, if there's no delay.

Did you get the cells at the ETA? How is the quality? Lastly, can you share the exact sellers link? There are so many shenzhen deriy names on Alibaba.

Actually, I don't think they are because i monitored it my self.. And according to the low and high volt I wrote above, that exactly what in the manual book as well... Was kind of expecting bulk charge at 29v or 28.+ but on the inverter and manual as well it is written 27v and 21.8 as low.. Reason why I said they don't use what is explained is, this ppl na my inlaw, Dr follow instructions like say his life depends on it... If you tell him not to on it all day self, he won't ask why since it your field, he will off it that him for you.. Now back to the problem, do you think the inverter could be affecting the batteries? Could it be that pumping machine affecting them..? Kindly not, the pump was only tested on the previous battery not run on them and them just went bad before this new ones.. Now this again..

My setup once again make una help me use Oju a gba wo abeg..(experience eye look am)
585w brand new jinko PV all connected in series x3
Welion 4.2kw hybrid invert with 120a cc
Then two 220ah tubular batteries.

When U hear anything abt load in renewable energy, do not limit yrself the Client's Load, think of electrical wiring fault, there might be a fault in the electrical wiring that is putting heavy load on that setup, U may with to disconnect the house and test the setup with an independent load.

Load.. Pumping machine 1HP
Inverter fridge/freezer.. At high 280w and when it start running it comes down to 80w at low.
Tv 32"led which is around 35w or there abt
Decoder.. Around 15w
Then DC bulb 5w btw 5 and 10pecs sah not sure..

Kindly note pump is used only when the intensity of the sun is high and na like 3 or 4 days interval. (they once share with me the clip when they on the pump, the PV took it up.. And the battery never left the bulk state. Pump was taking around 700w+ and the PV was bring down 900w+ and once the water is full and turned off the PV will come down to just 100w above what ever it is been drown from the inverter. It doesn't event touch the battery at all..

Tv.. This only comes up during the weekend..

Refrigerator is the only appliance that run on it from 8am to 5pm now i tell them to off by 3 since this issue came up.. Kindly note that even as at that 5pm they off it, the battery stage doesn't leave bulk state always full...

With all the listed above, what the way forward.. ed the battery seller alaye turned me for one side.. And this Instllation was done in May last mth..


Kindly note... I Hv customers that they run two 12v 220ah tubular with 24v system on pump for year with no issue.. So i don't belive that the issue pls.. One even use it along with his old fridge in his drug store.. But i always advise them to do so hen the sun is high.


Make una help me with solutions pls.. Should i take batteries to professional battery chargers for check up? What could be the cause of all this.. Pls i need solution bosses abeg 🙏 🙏 🙏 keep on seeing messages and WhatsApp calls from him asking for way forward always cut my mind 😔 😔 will be in the comment section. Thanks all.. One love

Any good installer around Nnewi Anambra state axis.

It could be because you have one of the earlier Growatt with 18a. I think the German guy said something like that on another video. Whatever the case get to your firmware number and ask Amos. It could be you need a firmware update.

Chief. What's up?
Got the 22A own.
What Jinko 580w or 625w config should be ok for this to get maximum generation?

You'd need at least three of the 580/625w in series. Maybe four sef.

Probably best-served just bolting as many of them in series as your budget allows. As long as you're not getting significant shading anyway.

Your inverter is limited to 22A and every Jinko above 400w has an isc of slightly over 11A. Ergo, it may not be ideal to connect them in parallel at all considering the issues some people here have had with Growatt inverters and PV configurations that supply above the rated max current.

Connect in series. Keeps your inverter happy and you save money in cable costs.

I want to go with 8x580w Jinko s in series since it has VOC of 51.02V (STC), so that's 408.16V, which is in the MPPT voltage range.
Was wondering if there'll be a better config option.

You'll be fine with that.

They've been challenged, let's await their defense.

Hello guys

I had a lightening incident at one of my friends place 5 nights ago, although all the system was off but it still managed to spoil the inverter system. That's not the problem now, the solar system has refused to charge well since then.
Usually on a bright day, you'd get upto 30a on the 60a pwn charge controller, but now when the sun is very high, we get max of 7a current and when the sun is just minimal it's at 0a.. we're planing on getting another CC to test it though but at the same time i think the issue might be from the Solar s which is weird to me because I've never had issues with solar s before..

My friend stays in another state so I've not been able to go check the system myself.. all the little troubleshooting we did was carried out by himself with me telling him what to do and how to do it.
The whole system is About 1 year old

I'll like some input here please

🙏

Bros check Gennex Technologies, they have some Canadian 600w & 605w their Voc is 41v they are like 1.5k cheaper or higher than Jinko s.

Update

Hello chief, gone there yesterday and did few of the things listed here... (Equalizer also changed the battery settings to flood on the inverter) .. Also went with felicity 60a cc sadly that one doesn't accept more than 145v but was still able to use it to charge cause of the poor weather although when the sun intensity increases, it started blinking the warning red light. Anyways that not where am going... what I noticed myself is that, the battery doesn't take more than 10mins before it runs from full charge to completely discharge which is from 25.+v to 21.8v. and also takes abt same mins (10mins) before it get full even to bulk and float level. Let me also call una attention to this, initially when i did the installation, they had two 100ah battery which i connected to it, after abt few days the batteries became so weak and dead. I was like maybe because they've been using those for going to 2yrs maybe that was why, then we got another one.. Brand new ones this time around two tubular batteries 12v 220ah then this issues again which am just so so confused ... I also noticed the battery will start decreasing just like a clock count down.. It doesn't back up at all ones the PV is been cut off.. Same thing the previous two 100ah did.. what is the way forward, what kind of solution can I use to tackle this problem pls.. Will be in the comment section... Thanks all..

their load is killing the batteries...or a dim possibility is that you got substandard batteries.
the wahala with leadacid battery is that it gets irreversibly damaged anytime the voltage goes below 10v, depending on the battery, some might make a better recovery than others...while some will die outright.

u didnt check the SPECIFIC GRAVITY OF THE ELECTROLYTE?...if weak/dilute, it may also cause similar issues..but its a long shot..

your best option is go for lithium battery, a 3.5kwh 24v lithium battery will handle those loads easy peasy....or get 6kwh pack to have more flexibilty

What sort of meter would work for this?
Would it allow setting max wattage too?

My bad I tot u are in Lagos, bt do ur calculation wella them and find out.

gadgetplanetng:
My s are not on the roof because of this.
Lightning seeks the highest conductor

This was my thought initially too until last Saturday when a client I did a fence PV installation that's about a year old with no complain whatsoever called . His system is off-grid, sachet inverter, switched off during a night thunderstorm.

He came back to find his inverter no longer working, but controller and other devices working fine.

I'm still wondering what happened.

2 other tenants with roof installation had their on line inverters taken out also.

LoRA WAN, GPRS& GPS Meters. They have a central Dashboard Portal where you can Manage Settings, s and other things. Clients can Apps to see their data and etc

mank1234:


1 and 2 is going overboard. Lightening do also happen before it rain and sometimes while grid is ON...

Personal, I don't think 1&2 are overboard if they are not very expensive to implement.

That was even where my mind was playing towards before Jones dropped them. How many times does thunder strike when there is no rainfall? Little to none actually.

I will do some market survey and see if it's a cost effective solution.
