Thank you mentor Ikenna your are such a humble and exceptional mentor. Watching this video I remember putting up a call to you to and your response was Waw!!!
First of all employ the services of an engineer he/she should individually check the battery voltage to ensure all are at the same voltage, one, two or more batteries in that setup might be lower in voltage than the rest, let's assume its a 48volts system 12v x 4 batteries = 48v, if for example if one battery is at 10.5v eg: 12+12+10.5+12 =46.5v, you can see it directly affects all the other batteries even if they are brand new and since they are connected in series it can never balance itself out. Secondly these are lead acid batteries, whether tubular or not you're never meant to discharge it below 50% of it's rated capacity, from the video you badly discharged it till it's sitting at 41.6v ÷ 4 = 10.4 per battery, that is a completely dead battery, my guess is that you have been doing that continuously for a very long time & there's a high chance that some of those batteries have sulphated which automatically results in very low performance no matter how well you charge it. One can easily observe from the video that you don't take care of the system at all. Thirdly buy two 2x4 or a 4x2 battery rack & tidy up your installation area it looks awful & a potential fire hazard waiting to happen, & let's not forget those tubular batteries sometimes leaks electrolytes acid which can most times corrode you floor. There are so many other things that i would also like to address like your panel setup how many watts (probably a lower watt panel) & how it's wired, my guess is maybe the initial setup was for 48v system with 4pcs of batteries only maybe along the line you personally decided to buy 4 more batteries to join making it 8pcs as we can see from the video, without considering whether the panels can charge it or not (assuming it's a lower watt panel).. Just employ the service of a professional so they can troubleshoot the system & correct any problems they find.
It’s very wrong to mix or combine different battery brand because the parameters will never be the same. Well done boss…. More wisdom boss.. Greetings from Ytech engineering services ltd
You said it all mr ikenna....most this guy's do not want to professional to their job for them because they feel is too expensive,so they go for cheaper options....I see this alot because I am into the solar field for some good number of years now...God bless you Mr ikenna
Sounds good. I have assorted batteries, so I decided to have separate charge controlers and have each battery limit the total power it can provide to the inverter/DC to DC converter. Will probably get hybrid inverters that you can attach to other hybrid inverters.
That looks like a 100amp knife switch, who knows the capacity of the inverter used, those wires on the battery are small for 38amps 12 v battery, not to talk of 220amp 12v batteries
Nawadays, electricians take solar jobs as solar experts. 1. Charge controller is very poor 2. No rack poor connections. 3. No breakers, voltage regulator or Spd. 4. Mixing of batteries is 100% no for me. 5. If a good solar Engr. Goes there, I can tell you, 4 batteries might give the client good satisfaction.
A few days ago a solar technician called me for an assistance. When he switched his camera for video call. I saw that his connection was done with a copper wire 😂😂😂
I believe people should save themselves the headache......why not just buy a lithium battery 5kwh minimum, for the money spent in buying those batteries.
This is not the bone of contention from this video. No matter what you buy, poor installation, poor design, substantial products,... will still land you on the same plane of inefficiency and breakdown.
