Ojigbijigbi!!!
The in-built AC charger will definitely reach 14.4v or maybe 15v for a 12v lead battery. Now to place 14.4v charging voltage on the Li-on pack with bypassed BMS means each cell getting at least 4.8v instead of 4.2v max. Bro, you have been lucky for 3 months.

I have inadvertently shorted 18650s couple of times and it has always been a frightening experience each time. Now imagine those edgy lithium chemistry 18650s catching fire from overcharge.

All DIY 18650 setups that I have are outside the house. Even the factory made banks that I tinkered with by adding extra batteries are all installed outside the house. In freaking metal casings!

Chief niyi

Needs recommendation on Reliable batteries 200AH.
Gennex Technologies do not have AGM or GEL, and I would havè gone for Quanta but they're not available either

So recommend another good one

Thanks

wait for quanta or contact Zeestone

Thanks so much

Finally hooked up, could not get a DC breaker with wattage low enough and voltage high enough locally but have found an appropriate one via AliExpress (20A/440v) so am running direct for now.
However I have a concern, at around 7:30 I was getting 440w harvest but now that I have turned it on with load, I am getting just a little above 220w and I am wondering why this is so. I thought with load the generation should increase, please what I am not doing right?

May be solar insolation is low or may be your priority setting is not right.

ojeysky:


Please how do I check solar isolation status? I confirm that my priority is set to solar only (as there isn't utility source for now)

Please what else could be wrong?

Thanks

mank1234:


Not enough sunshine.

ojeysky:


It's right on my roof, is it possible that it's throughout the day that it's not getting enough sunshine because I have not seen anything above 450w since morning. At the time of writing this, I am only receiving 0w

From this your pic, practically no solar radiation is hitting the panels at this time. And its obvious your panel tilt angle is waaaay below optimum. If you are in Lagos, I believe placing them with O° tilt would be best all year round.

Another factor you may have overlooked is one basic principle with long strings. Once there is partial shading on just a single panel in the string, whether via cloud cover or anything else, it drops the voltage of that string to the lowest value recorded by that panel. Hence, you are evidently getting the least possible voltage value from the string, even before it gets to your inbuilt mppt cc. That's one reason for avoiding long single strings though.

mank1234:


As posted above, orientation of the panel appears wrong judging solely from the picture.

What's the installed total panel capacity?

mank1234:


You've said it all. Weakest link determine the output.

I don buy market I guess way forward with minimal extra expense is what I can hope for now

Thanks @mank1234 @Dam5reey @GeorgeD1 we agree but the issue is that in the morning the sun is on the other side so I just choose one of the sides not knowing that I won't be getting any wattage in the afternoon.

@zellfoxx am not in Lagos, am in Ado-Ekiti by 0⁰ does it mean my roof can achieve an optimal harvest from sun rise to sun set and will need to setup a standalone?

can I use a 1200watt iron or a 1500watt water heater on the 3024 pip-gk (3000watt) inverter? would doing that be pushing the limits of the inverter?

zellfoxx:


Standalone setup would your best option. This is extra cost though as your roof pitch will not allow you reap the benefits of roof-mounted solar panels. At least you'll have longer duration for daily harvest. I also don't think getting adjustable roof-mounts will solve the issue.

Secondly, you need more panels in that string. So you can enjoy that your inverter. If you can hit 250V input at least, it'll save you alot of headache.

ojeysky:


By the way since you seem to be using same series with mine, how is performance of yours? What's your setup like?

Dam5reey:


Of course, Yes.

I use 450watts Iron on 500VA inverter.

Do you see voltage from your panels?

What type of charge controller do you have?

How are your panels wired?

Do you have breakers between your controller and your panels?

Answer and I can speak more to my suspicions.
