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
