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

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

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 pass 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.. Contacted 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

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.

PotatoSalad:

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

HeavenlyBang:


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 panel 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.

PotatoSalad:

Thanks.
I want to go with 8x580w Jinko panels 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.

This Build quality is top Notch, Flexible Busbars, Compression plates, Protection films, and Fuses, But some folks will still say rubbish about Felicity packs without any evidence.

Weldone Boss! Great Job!

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..

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

My panels are not on the roof because of this.
Lightning seeks the highest conductor

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

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