Hi Guys

So the SMK hybrid 3kva inverter installed at home have developed some weird charging patterns, this started after the main fuse in my junction box burnt. Ive since replaced it but right now when I connect the inverter to mains it starts charging from the set charging current of 25a, but after some 20mins this charging current would weirdly start dropping to 0a even though the battery hasn't gotten enough charge to warrant this current reduction. The typical pattern would be that it'd continuously maintain the set current till the battery has gotten to some 90%+.

Please how do I approach this? my hypothesis is that the inbuilt charging unit is broken but I cannot explain this.

Hello gurus in the house, due to this light situation, I’m doing an online course and I’m looking at installing a small solar system, ive been contacting people but I really don’t know much about this, I only need light to power my laptop which is 65w, be able to use fan (I’ll buy a fan of 30w or lower) and on 2 white bulbs for 8-10 hours daily.

These are what I got so far, please advice me as if you’re advising a novice because I don’t know anything about this.

1. 220k comes with 3 solar panels of 80w poly each and 15 yards solar wire with 150ah Lithium battery and inbuilt 1000w Inverter

2. 200Ah battery@130,000

1kva inverter system@85000

300watt solar panels@75,000x2=150,000

30amp charging controller@35,000

Installation kits/installation@50,000

Total @450,000 but this person said I can still get for 370k


Problem now is I feel this is a bit much just to get my laptop charged, please help analyze this and help me come up with something pocket friendly that will still work for what I need, they all keep asking me about TV but I don’t care about that, I just need my laptop on so I can work freely, thanks.

No price is firm Sir/Ma
Does the price include shipping?
No it doesn't, but I can waybill to any part of the country at buyer's cost.

Can a 1.5kva 24v inverter with 200ahm battery power a nexus nx170 refrigerator and other load of around 120w?

Could you post the picture of your ATS.
Tried another type/model of ATS?

In general these Axpert type clones are very failure prone - that is why I do not like them.

If you purchased direct from China, reach out to the seller and they will usually send you a replacement board under warranty to fit it yourself - of course do not mention that you had a fuse burn out in your mains supply - just focus on the issue.

If you purchased locally then invoke the warranty or repairs support or take it to the Arena and Alaba folks for a fix - I would rather replace the entire board myself than let our average half baked repairer tinker with the board - IMAO electronics repair skills and standards in Nigeria are terribly poor.

Yohako is a company that deceives. I bought a 2kva solar generator from them. They worote on the front that it has 110AH Lithium battery, but when I opened it, it contains only a Gel Cell lead acid battery. This Lithium battery you are selling I doubt if it's really Lithium, coming from Yohako. I will never buy any product from them again

Same issue with both ATS...

My brother forget about the name tubular all na lead acid. Please go for that lifePo4, i am enjoying mine now

Bros, how much

Team,
Please, I have two banks of Amaron Quanta the white carton type and the coloured carton type, (see the attached pic) both are bought about same time and has been fairly used, not more than max 60 -70% depth of discharge at few times and most time less than 50% DOD. I have a reason to combine the two banks for better efficiency and capacity, I have the intention to connect both to busbar and then connect the inverter/charger to the same busbar. I want the experienced hands to help confirm;
1. If the two battery has same charging parameters? If so what's the suggestion for the charging parameters.
2. Is there any confirmatory tests to verify these battery can be combined
3. I have a battery desuphator, can I connect this across the busbar? will it be effective.
4. One bank already has battery balancer with midpoint voltage monitoring, can I setup same for the second bank so the two banks has independent balancers or I should reconnect the whole battery into one big bank and put a single balance across.

Comments form all experienced hands in the house is appreciated

Why shouldn't he report his fuse got burnt? You called the axpert a failure, I know many that have used axpert for years till today. We just want to hide our own fault and discredit others. What could have burnt his fuse, it means there's an issue somewhere and he should fix that otherwise it could happen again.
Hybrids are very sensitive to lightening and power surges from mains. Many don't have a proper earthing or thunder arrestor system in place.

Good evening house,

Anybody with an idea of any device capable of converting split-phase 220VAC to normal single phase 220VAC source.

After installing a Felicity inverter, I discovered every other thing in the house is working fine, except the ATS (used, with a timer, to control freezer operation) . With NEPA, the ATS outputs fine, but with inverter output, it's "vibrating". Never experienced such issue with other inverters.
I was later made to understand that Felicity inverters have split phase output source, hence its not compatible with the ATS coil.

Anyone with idea of a device that can serve in between or with an alternative solution... Thanks.

NiyiOmoIyunade:
The official answer is not to combine batteries that were not commissioned and used exactly thesame - some will even tell you they must come from thesame production batch

In reality you may succeed in this enterprise but the first question is what is your inverter nominal voltage?

If you are setup as 12v then your scheme should work no trouble - 24v or 48v nominal is where things get spicy...
