Boss. Bad as e bad that Yohako MPPT CC should be able to reach absorb voltage of between 14.1v and 14.8v - are you sure that you have sufficient PV panels capacity to run your house loads and recharge your batteries to full? That could be the issue here. Of course I know nothing about 'Soccer Power' inverter sha

As for buying grey market el cheapo batteries you would still buy four pieces yeah? Even at 70k for a cheapo 12v 200Ah battery do you really want to throw away 280k within one year? Better to just bite the bullet once and replace with the long term in mind - except you can lay hands on fairly used batteries in good condition sha.

na real grey market batteries, hehe

I'm a 100% certain that the panels aren't the issue. Though the configuration of the panels could always be changed later on for more efficiency (i.e 3 in series as opposed to 2 in series as it is now), they are supplying enough for our needs. We have 2000 watts in nameplate panel power and on good days, I see above 20amps coming in.

For instance now, there has been mains supply for a while, so the batteries aren't loaded and are just charging, yet the controller never goes past around 55-56v, even with charging support from mains, via the 48v inverter. I don't even know if this thing does true mppt, cause most mppt controllers I've seen on this thread will show you the current hitting the controller and the converted current hitting the batteries. This one doesn't show you the current hitting the controller, only the battery, makes me wonder, like "what are you hiding" I'm sha okay with the controller and the power coming in, so i don't think i will change it.

I figured since i just bought a 12v inverter capable of reaching absorb, that if i bought new cheap batteries now, i could always disconnect and charge them individually with that 12v inverter, say, every 3 days or so, to make sure they are really charged to 100%, not the 100% the 48v inverter and controller display, which is really about 80% in my opinion. That way, I could ward of sulfation before it gets a chance to set.

You're right though, I may have to bite the bullet and change the inverter and batteries all at once, but man, that is a very salty and bitter bullet to swallow at this point in my life

so may go for cheap 50k, 150ah batteries and pamper them.

Should have gotten back to this group earlier, just been very busy.'

I was complaining before that my charge controller might be toast, because i had disconnected it from the battery in the day time without disconnecting the solar input first.

I am please to report that the charge controller made it

My batteries are still dead though, 200ah batteries have now become 10ah batteries

I suspect that it is due to the wretched inverter the installer supplied (soccer power ). Honestly, these installers don't really care about you, they just want to make a sale and that's it.

I have been doing alot of research on battery float usage and cyclic usage. In cyclic usage, it is recommended that you charge up the batteries to around 14.1 for gell and 14.4-14.8 for AGM batteries, before reverting back to a float voltage of 13.6-13.8. The inverter that i have only does a float charge at 13.8, same with the charge controller. Both never hit absorb at all.

I bought a 12v inverter to try to charge each battery separately, up to 14.1volts, but it seems like it may be a case of "too little, too late"!

I don't have money now, so i will have to buy 4 cheap batteries in the meantime, cause there really is no use of buying expensive batteries when you don't have the right equipment to ensure that they are well taken care off.

My next upgrade after that would be to buy a Must 48v inverter that employs charging pertinent to cyclic usage, giving me the option to select battery type as well. That way, i'd be sure that my batteries hit the absorb voltage every night.


Thanks to all for the advice, you guys are really cool, knowledgeable and helpful. oh, i have now installed a dc circuit breaker between the panels and the charge controller, so that i avoid any stories that touch moving forward

Your number is switched off.. Interested in heavy rain and gta v

Hey twixx, sorry my phone battery is dead, charging now.

Those games are still available though, I'm located in Victoria Island.

You can call me in like 30 minutes, my phone will be on, thanks!

cutie pie, I hope buhari is watching sha


please guys, need to sell this xbox one controller, pics here: https://www.nairaland.com/4326278/xbox-one-controller-sale-10k

so if you have an xbox one, why pay twice the price? when you can get an original U.S.A product for dirt cheap.

do you have an xbox one? need a new controller?

click here to buy one now : https://www.nairaland.com/4326278/xbox-one-controller-sale-13k

Op, ur 300km to Benin is incorrect. You didn't add 100km for staying in traffic and downtime to bad roads

electric vehicles are more efficient sef just sitting in traffic bro

kpaofame:
Nice one if you know what we went through to secure a meter after about #12k monthly bill for low voltage... sad experience

This is a step in the right direction, Very laudable, actions like this is what we expect our government to do, not charade claiming they are performing...

you have very adorable switches, very cute

some people here are saying no light, that they even have to buy extra power bank for their phones.

my question is, how do you charge that extra power bank
