My two panels, dey give 200w-400w on a cloudy day. But when sun show sometimes I dey hit 1kw

Which product and how many watt

ajabani4allah:
I was trying to get to the cell probably I would see a bar code I could scan or see where they write the capacity but this was not possible as all the cells were welded and covered up, not the bolt and nut type. I will try the capacity test next weekend. Below is the final built after combining the two metal case by my welder

I'll await the capacity test. Thanks plenty

osayuwamwen:
I they wonder how battery take they deplete to 0% and battery won't wake, is the internal bms only for balancing ? all this cheap substandard battery, una they laugh me here when I bought humsienk 12v 314ah lifep04 battery, before I install my hybrid inverter then I was using the battery on sachet inverter were i drain the battery to as low as 10v and the bms nor they short down

Pls how low does it go now that you are on 24v and at what voltage does it stop charging?

Jinko bifacial 535W

What's you daily average generation with this single panel?
Thanks

Hello guys, I have a 1.5kVA Haisic inverter with one 535W Jinko bifacial panel installed. The single panel is not generating enough power to fully charge the battery during the day, so I still rely heavily on grid power to top it up.
I want to add another panel, but I can no longer find the exact 535W Jinko bifacial model I bought.
My question is, can I add a different panel (for example, monocrystalline panel) to work together with the existing Jinko bifacial one, or must I use the exact same 535W Jinko bifacial model?

Gshems:
I also use a 12v system. 2 535w is fine. My battery gets full everyday. I don't even charge with nepa.

What is the capacity of your 12v battery?

My night load after 10:30 is less than 100w

fuckboys:
chief, we're better than millions of Nigerians without electricity o. No matter how small the setup is.

Once is 7pm the house loads reduces to under 300w till daybreak. I still keep cooking gas for night food warming only. Fresh food cooking must happen during the day time with induction cooker.

4kw

Omoh I think there is something probably wrong with my panel but I’ll see what happens when I get the second panel though. Because my single 535 watt should be giving me at around 400 during peak but all I get is within the range of 200 to 300.

200 to 300 during peak hours

Hi everyone,I need help reviving a HenryLFE 12V 150Ah battery drained to 10.24V. The BMS is locked and the Bluetooth signal has disappeared (it won't show up on any phone/app).What we've tried:14.6V 20A LiFePO4 Charger: Won’t start; doesn't "see" the battery.Parallel Jump: Tried jumping with another battery, but the BMS won't wake up or allow the charger to take over. Help

Another thing is the placement of your panel. Where is it facing? Is there a shade casting on your panel?

Why una dey drain battery to 10.24v? When I was using 100ah lead acid sef I no drain am pass 12.0v. When I moved to joykoo 100ah, that one no ever pass 12.9v

it may be the direction we're the panel is place and ensure no shading

How did you measure this ?

Asking because a lot of times, these charge controllers / hybrid inverter's displays what they are drawing.

Another ensure no Shading, and no DUST as dust sef can shade your solar panels

Were you using NEPA or Solar to charge the battery ?

Some times when Lithium batteries stop charging, it's mostly BMS related. Have you contacted the company ? Those their touted afterSales blablabla and Warantee and Guarantee, etc should be put to test now.

Also could be appreciated if the likes of @valto or @mrReed could provide what's called CooperateSocialResponsibility. No worry, we understand

What was the voltage and the amp capacity of the battery you used? You might need to give the batteries a few hours to rest and repeat the parallel connection, especially so IF the BMS has low Charge amparage.
Others may have a better opinion but what I had to do once upon a time was to connect an appropriate voltage solar panel to the battery briefly under monitoring and the BMS woke up

the parallel jump may not work because of the inrush current, you need a "dumb" charger to wake it or use your solar panel early in the morning before the sun intensity is high. You can also use a 15v TV or laptop adapter to wake it

Gshems:
Na just 600w range. I tried it on the highest level and Ẹ no enter 700w

True. I use silver crest also, it is rated 2000w or so but it actually consumes far less than that

Gshems:
4kw

Wow!
And just 2panels of 535w charges it full with load on it daily?

justasitis:
I normally recommend: Bulk/Constant Voltage Charge : 28.4v
Floating Voltage: 27.8v or 27.7v
So that the battery Resting Voltage will be around: 27.2V

Cut off voltage of my battery BMS(UVP) is 3.55v(28.4v), so I set the Bulk/Constant Voltage charge of the inverter: 28.6v and
Floating Voltage: 27.8v but my battery never get charged pass 27.8v instead of 28.4v. I later changed the the floating Voltage to 28.4v and the battery now charge up to the 28.4v. pls is this setting ok I can see that the battery is charging according to the floating voltage instead of the Bulk/Constant voltage?

what inverter do you use?

This is lithium battery. Your 28.6 for bulk and floating is ok.

trying to charge it wouldn't work, cos the bms is not active due to very low voltage. the solution is to open the battery and try charging directly on the cells terminals to atleast 12v, it will wake up the bms.

I Dont deep discharge my battery. Most times I wake up with 13.0v. My freezer is only on during the day. I only use lights fans and TV at night. I manage my load prudently

please boss, do you know of anyone in Lagos that can render this service, I will reallly appreciate , God bless

Just open the battery. Look for where the - ve and +ve that was connected to the bms is. Connect your 12v charge directly to the terminals. You can Check solaris surge YouTube channel. He once opened a 12v 100ah battery. Just follow the steps

ok I cant find a point to open the battery, it looks perfectly sealed

Na screwdriver you go use pry am or anything flat

wahala. there is a way to open them sha, but not easy.
btw, a good 12v smart bms shouldn't be totally shutting down at 10.2v.
