Structuralman:
How many litres of coolant did you pour in the radiator?

2litres

9icetoo:
Your thermostat has been reinstalled. Your car now gets to optimum operating temp quicker and the ecu now adjusts fuel efficiently. Hence the improvement in fuel economy. You are doing well.

That might be the most logical explanation for it. Thanks

9icetoo:
Was your thermostat reinstalled after this coolant was added?

Yes....that was some months before the coolant was added. No improvement in mileage then. It was exactly after coolant was added that I saw improvement in mileage

Okoyedavid3:
My bro, this kinda thing one can't really tell.... I leave that to the expert in the house....

If I may ask does your temp gauge now read half way as compared to before..!!

.

What I noticed is that it reaches half gauge faster than before. Before it takes more than 10mimutes of driving to reach half gauge, now it takes roughly 2minutes of driving. Though it still slightly below the mid(half) line. Another thing am thinking maybe the weather might be another contributory factor. Since January the weather has been hotter

Please House, does coolant have effect on a car mileage? The reason am asking is because I discovered after adding coolant to my radiator for the first time in January, since then have noticed appreciable increase(improvement) in mileage, infact my car breathes better, covers the same distance with almost half the same litres. Am trying to know what I did right that could cause that significant increase in mileage. Before my Honda pilot covers about 65miles with 30litres, now the same 30litres gives roughly 100miles(this is only city driving with frequent stop and go)

To all the people that have lost their hybrid so sorry to hear this, I remember not long ago we discussed this predicament and what will be the way forward....is axpert clone brand not solid enough.
Well I still remain team standalone cc and standalone inverter.... Signing out.

The problem might be the lithium support with BMS. Am sure with time they will level up with standalone interns of robustness, security and protection

ojeysky:
That's right at least I have an idea of the cause and thanks to MPP replacement warranty. Nevertheless those "first tier" are sure thing so long as the user's budget is sure as well

Please what was the cause

saint2ace:
If u had answered differently or acted otherwise I would have been surprised, but as expected u never disappointed and u just have to show Ur level of decorum..........

Bros take am easy....everyone can't be here for the same reason. Allow this people to thrive. Justemmanuel, wilmaria14, kiekie and others are here to use this platform to grow there businesses, please let's allow them. It shouldn't cause fight as far as they ain't breaking the rules

posty56:
they are no longer accepting Nigerians sir

I have been on the platform for sometime......it just that I always have issues with ID verification. Does anyone knows how they go about it. I still want to try whether they've stopped Nigerians or not

Please House....Have been having challenge verifying my account on T212. It's requesting for ID and selfie, but the ones I supplied have been declined on couple of occasions. How should I go about it, does anyone know the exact documents needed

abbeymighty:
how many kva and v is it?

5kva/48v

NiyiOmoIyunade:
Every DIYer or pro installer must have a multimeter capable of DC voltage measurements at the minimum - if you can measure DC amps with a clamp then all the better.

With a cheap mulitmeter, you can check battery and PV connections for voltage and correct DC polarity and avoid expensive or dangerous mistakes.

Thanks Sir.....Noted

Sorotec 24v 3.2kw, Valto listed one for sale a while ago, whaf i have now is 48v 3.2kw.
@lovelynife, icell, sorotec, deye.... Even musf and felicity dont hv editable settings, but they have battery sel3ctor switch with diff voltages, which will also serve same function

Am using felicity hybrid with luminous 220ah wet cell batteries.......it's editable. Though Maximum voltage is 58.4v with equalization function. It works well for the batteries and charges very fast. Carries my whole flat, My freezer runs on it 24/7. Funnily I cook with it everyday(use 1.8kw infrared fast burner)

IYGEAL:
That may be possible but very unlikely. The sound was reminiscent of a capacitor forced to discharge.

What the inverter does now is produce a massive spark on trying to connect it to the battery. Sometimes it shorts off the battery. The sparks are big enough that they almost washed off the threads of the battery terminal.

Since the repair guys don't seem to have any clue as to how to fix it, I'd go take it back and try to feed it PV first to see if it would wake up.

It happened to me when I was installing my new felicity inverter, gave off big sparks, at a point melted the lead of one f the battery terminals and one f the battery rack iron rod. My wife was scared. I made 3 attempts, similar event happened the 3 times, until I called an installer friend who put me through. First be sure the batteries are properly connected. My problem was I was moving from 24v to 48v system, battery connection is different. Be sure there is no short circuit. You can call an installer to take a look at the connections

lastchild:
I never knew something like this is possible, where did they get the flesh to cover it, because i know that the lips wasn't stretched

The upper lip muscles were released, then advanced to cover the defect

ojesymsym:
In addition to this, the inverter is better off being a transformer based inverter.

An hybrid can also do the job since he might need to incorporate solar panels. No need buying a separate Charge Controller. It saves cost. 3.5kva genuinely rated hybrid will do the job

OCTAVO:
Does anyone here use PowerStar W7 inverter? While checking through online reviews I saw that the idle power is over 200w, is this still true for newer productions? Idle power more than 25w is unacceptable for me, because the inverter alone can run battery down quickly (for someone like me that have very few batteries).
This is why I like Souer, believe me they have one of the best power efficient inverters out there (though mostly MSW). I can leave Souer inverter on for hours without worries of power drainage.
Please I need your honest opinion about PowerStar W7 3.5kv inverter.

Get an hybrid inverter instead.....the idle load consumption is relatively low. Felicity hybrid 5kva is about 45w, sometimes can be lower.

ojeysky:
I know for Felicity variant you can't do both solar and utility charging, it's either of them. So maybe you isolate solar and then see if utility charging works. There should also be an option to set charging source, I hope it's not solar only

In addition....solar and utility(Both) charging applies to the higher model(4 or 5kva). Maybe he should reset the inverter to default settings. I think it will work

Is there any performance/efficiency gain with inverters PF=1 over inverters with PF=0.8 . PF means power factor

mctfopt:
This is correct. An "expert" nearly fried an inverter this way when the connection was 4s 3p (250w @ 38VoC) for 12 PVs instead of 3s 4p. Most Chinese hybrid inverter have 150v as their max input voltage; especially for capacity not higher than 5kvA

.
You are right. It's actually 145v max. I think I will manage the pv production. Will augment with Phcn. I appreciate everyone contribution. Thanks

ojeysky:
That's very wrong, please change it to 4s2p

My inverter VOC is 145vdc max. Each of my panel VOC is 37.44. The Max I can do is 3s. 4s will be too much for the inverter

earthrealm:
IN addition, hope you dont have these send down the rain/ high pitched roofs, thats one of the greatest culprits of poor harvest, then wrong config of panels, wiring for pwm, instead of mppt

You are right.....the roof is very steep. That was the only option I had

ojeysky:
That's definitely not right, you need to provide some more information though:
1. Is there demand (load) beyond 900w
2. How are the panels connected?
3. What's the CC spec
4. What's the battery specs
5. What's the charge voltage and current settings

Etc

Yes even with load more than 1.5kw in full bright sunlight, the pv production is barely 850kw
2 Am using the inbuilt controller that came with the hybrid inverter. It's 80a Mppt

3 It's 48v 2s4p of 270w mono panel each

ojeysky:
Try this one

That's one beautiful display.....the maximum peak harvest have seen from my pv is less than 900w. Is that normal considering it's less than 45% of my solar array(total pv=2.16kw)?

earthrealm:
Load 102% , Abi my eye is omitting a decimal point.
Meamwhile this display is old school..
Check out tjis display

It's actually 102%. I guess those displays are on newer hybrid models

Valto:
this is not good for your battery at all. i hope u don't try that often. your batteries going below 11V each, under heavy load, will affect its lifespan!

I rarely do that.....I did that to test the capacity of the inverter.

Please how do you attach pictures.....am experiencing difficulty

badaru1:
Good morning guys, please I have a question, which is better for solar energy, Hybrid inverter or normal inverter with MPPT?

I was using a standalone inverter(bluegate transformer based 3.5kva/24v) before recently porting to an hybrid system because I needed a 48v system coupled with some pv installations.
Now am using felicity hybrid 5kva/48v.
These are my observations
The transformer bluegate is heavier and very rugged. I ran virtually everything in my house on it with no problem. The fans are naturally louder than the felicity hybrid
In terms of performance i will say they are both good...... though I feel bluegate of equal kva as the hybrid might be a bit stronger. There is a caveat I was able to run 100% of the hybrid capacity this morning on battery with no problem though evident higher fan noise. The Max I have done on the bluegate is 70% of it's capacity. The reason I pushed the hybrid to it's limit was because my wife was sceptical about it. She felt it might not be able to power loads like the bluegate, since we want to send the bluegate to my Mum.
The no load/self consumption of the hybrid is lower
The presence of a charge controller on the hybrid is an advantage.
Anyone is good. Just know if you are installing a standalone inverter you might end up coughing out more money for a controller later if you eventually add panels to your setup

Below are pictures of my load testing of the felicity hybrid

Oga Adrusa, Ojeysky...... I recently installed felicity hybrid 5kva inverter. Things going for it, 48v and mppt controller. Compared to my bluegate inverter, its lighter though looks well made(well weight might be deceiving), lacks AVR(just bypasses the input grid) and makes high fan noise when charging (decreasing the charging current reduces the fan noise). One thing I like is the low idle consumption about 45watts. Anything to improve the experience, datalogging
