Obimind1:

The batteries that went bad were Gel batteries, but presently my batteries are AGM.

Ahhhhh.. No wonder they died in 8 months. Of all the lead acid battery type. Gel is the most finicky when it comes to charging. Gel batteries are notorious for having low rate of charge and discharge and are very choosy of the type of charger u use and can be damaged with high voltage has you have experienced. In fact most gel batteries cycles between 13.2-14.1 and they tolerate no form of equalization whatsoever.

Let your experience be a cautionary tale for everyone reading this. Research matters alot. If you can't so the research get a competent installer to do it for you. The downside of jumping into solar is getting your hands and pocket burnt. The problem is not mppt or pwm its the fact that u didn't have enough knowledge on battery types and their recommended charge profile. I sold my first controller because it was not capable of properly equalizing my batteries. I got one which had adjustable change profile settings. If u want to go DIY u have to know and understand every single aspect of the game. Battery type and their charge profile, controller Pv cabling load type of inverters every single thing a mistake in one aspect can leave your system failing u in a short time. The 2 batteries I got when I started my offgrid journey are still running going 2 years now and they are doing very great. All those readings did pay off

My setup and advise on improvement or do good maintenance?

PV array: 2 piece of 130w mono
30ah CC
250ah 12v battery - Lifepo4 battery
1kva Inverter


So far everything works great!

brethren... I don come with my questions again o
pls can the charging state of a cc affect the charging state of the inverter.
I ask becos a friends TriStar45 will normally indicate high voltage disconnect just after about 3 hours of charging and about 15mins later, the inverter stops charging too(meaning ba3 is full). Nw jst after 8 months, doz ba3s r gone. So I'm thinking maybe d cc is sending wrong info to the inverter or d ba3s r not good to begin with.

I have not used TriStar 45 but I know it is a powerful CC and it should have GT Mode function.

I will advice u state the type of ur inverter or snap both cc & inverter so dat those with similar type can assist you with settings.

It looks like the electrician in the picture is using his pliers to twist two solar cables together. Correct me If I am wrong . There is nothing else with the solar installation which requires pliers.
I have long frowned on such practice. The correct way to do is use MC4 connectors and couplers with their low price there is really no excuse

Are u not using a BMS with Lifepo4 is the CC and inverter capable of handling LIfepo4? Otherwise, you are reducing the life of the battery . Lifepo4 charge and discharge have to be adjusted based on battery temperature

If the Tristar was started with Solar PV first before the battery was connected it might have registered wrong battery type of voltage specially with the discharged battery.

Check the dip switch settings for battery type and voltage as Auto settings sometimes get fooled

Obimind1:
Its been over a month now, I lost my batteries and my charge controller(60ah mppt) all at the same time under 8months of usage. It was a tough time for me though, but the truth was that I had no one to run to. I managed to get a set of new batteries which will clock one month on the 19th of this month. I also had to fall back to my 30ah and 20ah pwm charge controller which I dumped sometime ago. Now this are my findings: I noticed that my pwm seem to have an effective cut off strength compared to my mppt cc. My pwm does not exceed 28.2v at peak Sun periods and even when I'm charging my batteries with national grid power(Phcn), but when I was using my mppt I noticed that at peak periods my cc voltage rises up to 30v and every 28 day of the month it shows that its equalizing at this point my battery voltage rises to 32v during peak Sun hours. To cut the long story short I lost my batteries and my precious 60ah mppt cc under eight months. My charge controller started showing (battery OVD). Now I'm starting all over again. I must say I learnt my lessons the hard way. Had I known I would have maintained my pwm which I was using conveniently for over a year b4 going mppt. If I am to go the mppt way again, I have to do a lot of research to know what capacity of mppt cc will be efficient for my 24v set up.

A good reason first-timers are advised to use starter batteries. The learning curve can be steep. And quite expensive, literally and figuratively. Thank God you didn't have a fire nor any of the other possible hazards.

downloaded and read the manual for the TriStar 45 and to my amazement, it was stated categorically that there are no set charging settings for the sealed maintenance free ba3s as they are "unreliable". guess we'll have to go with custom settings and please what voltages would u recommend for the bulk, absorb and float charging states.
And my question still remains, even if the cc is confused as to how to charge the ba3s effectively, is that suppose to affect how the inverter charges the ba3s too? (its a SKG inverter, 1.5kva 24volts)

I am a bit confused about ba3 . is it a type of battery or manufacturer name- A quick google search revealed only OLX ads and Nairaland. What is the make of battery? you may find the recommended settings on the manufacturer's web page
Knowing battery chemistry is important before making the settings

see this link on morningstars webpage - https://www.morningstarcorp.com/morningstar-best-practices-battery-chemistry/

another excellent source is - http://batteryuniversity.com/learn/article/charging_the_lead_acid_battery

I am doubtful if the SKG has temperature compensation or four stage adaptive charging looking at the picture.
Good settings in morningstar should keep your battery at peak performance

how good is gel battery vs Agm battery?

good choice. some agm batteries can actually take up to 50c charging current.

i'm using agm batteries. quite rugged, i tell u.

Okaya is Indian Brand but the website does not inspire confidence - NO datasheets or charge curves. I have sent them a message for datasheet. Let's see if they respond

RE: pls house. i have 2pcs 200w(sunshine) and 1pc 150w(focus) mono panels. i want to buy one more panel to make it 4 pcs, to be connected to a 30amps mppt cc with a 24v pure sine inverter. whats the best option for me? should i buy 1 more 150w or 200w panel? whats the best series connection for me?

Oshomo12:


Upload the specs of the two panels, stating all voltages and the currents u see at back of the panels.

i av gotten the spec of the 150w panel
current at pmax (IM) =8.20A
voltage at pmax (VOC) =18.30V
short circuit current (ISC) =8.72A
poen circuit voltage (VOC) =22.40V

Suppliers/Dealers/Engineers etc in the house.

I am in need of a Pure Sine Wave Inverter (inverter only). I do not need the charger as I live completely off-grid and charge my batteries with my PV arrays only. I have a backup generator, but I do not charge the batteries with it. It is purely for backup. The capacity of the Pure Sine Wave Inverter only should be between 6KW and 8KW, and able to power submersible pumps, refrigerators, air conditioners, pressing irons, washing machines, dryers and other household appliances and office equipment. It should also be able to power small power tools such as drilling and cutting machines

The inverter should be a low self-consumption inverter.

Cheers

What is your battery configurations. Volts and Ah.
What is the solar array capacity?
Do you intend to run all the mentioned loads simultaneously?
Thanks.

Hmmmmm... all the loads has "s" to them. Not just one of each but many of each.

why not kukuma use the inverter and power the generator too
