Nope, electrolyte is water that has already been mixed with acid.----you should never add this to a flooded battery in use, as it will distort the acid-water balance, making the electrolyte too acidic.
And corrode the cells inside...leading to premature battery death.

You should only add distilled water to a flooded battery already in use

Thanks for this explanation, I was confused seeing recommendation to use distilled water for flooded battery, and in another recommendation, electrolyte is what would be recommended, which made me more confused on the right one to use for the battery.

Namzy, you seem to understand my point. I think some people on this tread think I am attacking SOROTEC. I only have issues with the particular inverter I bought. Also the seller assured me of the durability of the inverter compared to the other ones he is selling. From day one, I started observing strange things abt the inverter. On the first or second comment I made, I said the SOROTEC logo was poorly printed on the inverter which made me to reach out to Sorotec directly to confirm if this inverter is truly made by Sorotec & the lady on the other end confirmed that the Inverter is genuinely Sorotec.

Its possible, Sorotec did not make this perticular inverter & only put there logo on it. For those trying to defend Sorotec, go and buy this perticular inverter & after 6 months, come & give us your feed back. Abt four persons have given a negative review abt this perticular inverter. I also strongly believe, the inverter capacity is not up to 3.5kw. I stand to be corrected

Namzy:


I understand your plight and I believe you are right with been unsatisfied with sorotec. It seems these axpert clones apart from maybe growatt/felicity have same issue of unreliability. I have a 3kva ipowerplus which is an axpert inverter and occasionally run a freezer, 1.5hp inverter ac and fridge and nothing happened. Said inverter was bought 2018 and was retired after a thunder strike late last year, I bought exactly same inverter again and currently enjoying it. A simple Google search will reveal the unreliability of these axpert clones. There's even a decidated thread on it. It's a pity a known brand like sorotec will slap their name on those clones because I'm sure those inverter were not produced in house and therefore not as robust as their other models. I assisted a friend in getting such a clone because it has his desired capacity(3.5kva) and inverter didn't even last up to 6 months, now he has lost interest in HF inverters as it couldn't be repaired. These clones are hit or miss

As for you friends inverter, I want to believe, it can be repaired. My was repaired buy a guy in Lagos. I have lost faith in that inverter.

I have taking note of your point. Kindly send me a link to YouTube video that explains how a inverter compressor can present itself as an inductive load. I tend to comprehend things like this by watching a good video. Thanks for the info.

NiyiOmoIyunade:
I read you correctly boss about what type of AC you use(d). You quoted me but neglected to read what I actually wrote and I have now bolded below.

Without going too technical, your inverter AC uses a VFD to achieve energy savings and some pf efficiency by regulating the compressor motor speed - this process involves taking AC from the mains, rectifying to DC and then inverting back to a different AC waveform to drive the compressor motor.

The workings of the VFD (inverter drive) create voltage spikes/transients/back emf and harmonic distortions which your HF inverter is very ill equipped to handle - it is not just a question of the load wattage your Sorotec saw, but all the noise and distortions and faults and transients generated in the power line as the VFD ran. In fact you may have been better off with a standard 1hp AC mated to the Sorotec.

Beyond the technicals above, it is common for el cheapos to have capacity overstated - they may well use the surge capacity as the running capacity of the machine. Also temperature derating when you use the inverter in a non climate controlled room is a thing.

You already took your loss so let me not belabour the point, all these are for other users to be guided - it is best with el cheapo products to load conservatively say a max of 50% including surge i.e your peak load including spikes should stay well within 50% of the advertised running capacity - only go more aggressive if you have verified your particular machine to be built for that duty cycle.

My brother, your experience is what makes this thread strong. You are advising people ahead.
This issue was brought up a while back about inverter ac , and whether to use transformer based inverters.
I opted for transformer based inverters and I stuck with my normal ac. And it has been fine my neighbors inverter ac , keeps giving the guy problems and does not chill very well.

Sorry for your loss.

You will need an external LVD device that does the job for you, that way you won't have issue waking up the battery.

Please can you connect me with the cheapest one available

What's your inverter setup like, which inverter did you get and what AC capacity are you using on it?

Hi everyone, please my colleagues and I are having difficulties at arriving where the output of Fronius Primo PV Inverter 8.5–1 with a Conext XW + 8548 E should be connected to (Meanwhile, it is connected AC 1. There is a space for AC 2) I have attached picture for your perusal. Thank you.

Trippledots:

Inverter is a transformer based, 5kva and 7.5kva inverter. Both carry my 1.5hp and 2 hp chigo ac. But of course 7.5kva does it better. And I don't on the 2 ac on the 5kva, but I can the 2 ac on the 7 .5 kva inverter.

Good morning my people, please I am in need of a small inverter (used) may be 900va or 1kva for a small project. If anyone has a working one that is discarded or kept and not being used and the person wants to sell, please I am interested. It must be PSN.

As for the inverter AC not working well. It could be the filter is full of dust & blocked. This must be cleaned as often as possible. This I do when am around. For me, am enjoying my AC. No issues at all with them.

NIYIOMOLyunADE is the resident victron boss, this is his turf

durodee:
Hmmm. Sorotec. I have a 5.5kw unit (bought late last year) acting up. Displaying error 32. Manual says it's a communication failure between inverter and remote display. It will not connect to battery and when switched on by solar imput, will temporary display no battery mode before bringing out the error.
I had to put back my backup 5kw Gennex while waiting for the resolution.
My battery is 12kwh LiFePo4 and connected to the battery through positive and negative power cables only.

Useless inverter @sorotec Revo ii pro or whatever it is called. I don’t have to list issues cos it is more numerous than I have the energy for. Sorotec is not my first rodeo so I know a well built inverter.

Ah !!! Dis one that Sorotec is receiving woto-woto left right and centre like this......

I don't think Felicity Inverters have received this kain bashing maybe their batteries.

HAHAHAHAHAHAHAHAHAHA, men dey vex.
i have had good experience with sorotec, though their high end brand, the revo ii and the REVO E models. the oldest unit I have installed will clock 3yrs later this year

If you can review a 10kw solar setup for a school. It was installed for my sisters school but it seems substandard solar equipments was used.
Send me a Whatsapp on 0803361sevenfoureightnine

I'd check for some and revert back.

Kindly remind me incase I am immense in personal activities.

I do not much experience with Schneider with fronius but I believe the AC 1 is the primary source of power output from the inverter and AC 2 would be meamt for auxiliary output based on certain conditions.

Under an ideal case, since the aim is to form a mini grid with the inverter then having them meet on the AC 1 is the right way to go.

Nexuspulse:

This looks like a ready install where these questions should have already been answered at the design stage.

TLDR;;; - you very likely want the AC Coupled Option 2 below - by now I believe Schneider must have made firmware updates that make things better and smoother for the system designer/installer

Broadly, you can use the Fronius PV inverter in one of 2 ways

1) Grid-tie;- where you connect the Fronius and Mains into AC In 1 - in this config, the Fronius will only make power from PV where mains is available - without mains, it will shut down and go to sleep. This is the simplest usage scenario optimized for selling excess PV to grid.

The PV energy from the Fronius will first go to supply loads on AC Out and battery charging and all the excess will be exported to grid - big downside there will be no PV energy made when mains is down so not suitable for offgrid - there are a couple of schemes that may work around this but need extra expenditure.

2) AC Coupled;- this scenario is suitable for offgrid use and essentially sets up a micro grid where you connect the Fronius Inverter to the Schneider AC Out. Certain settings need to have been preset or else sparks may fly - see caveats below

a) Appropriate micro grid settings (e.g MG 50) selected on the Fronius

b) Schneider Conext XW+ or Pro must have appropriate frequency shift settings configured

c) A generator connected to AC In 2 must be fitted with a certain Schneider approved contactor/relay that opens the Fronius PV input whenever the generator is running. You do not, I repeat you do not want to feed in excess PV energy into your generator or else something must break. Of course you can jury rig your own contactor to isolate the PV but warranty is lost.

d) Battery charging by reversing energy from the Schneider AC Out is not automatic - care must be taken to configure appropriate [b] time of use [\b] settings for battery charging - you may need a PLC or Raspberry Pi or other logic controller to make this work smoothly for you else a lot of the Fronius PV potential will be wasted.

e) Size of Fronius PV can not over power the Schneider AC Out - Victron use the factor 1:1 rule so a 6kw inverter can only be mated with a max of 6kw PV or Fronius inverter size limited to 6kw PV output/passthrough - Schneider relax this rule somewhat so allow a roughly 1:1.3 size ratio but I would advise to stick to 1:1 as a max for safety and tolerance.

f) The Fronius will only run when it can sense electricity and then it wakes up and syncs its frequency to match - if your system goes off due to low battery, the Fronius cannot automatically wake it up next solar day, you will need to cold boot the system or preferably have a separate PV with a DC coupled charge controller to put some energy in the batteries and eventually wake the system up.

I could not see any DC coupled elements in your picture and this part is critical to a stable system especially if targeted for industrial use or mission critical

For the pundits when I say connect the Fronius to Inverter AC Out or Mains supply, I expect a distribution/bus bar arrangement with appropriate fusing/breaking and isolation for [Mains supply + Fronius Output + Inverter AC In] or [Inverter AC Out + Fronius Output + Inverter Loads] - essentially you must be able to separately isolate each and every of the energy generators, processors and centrally the consumers for a code compliant install.

These are some of the things I remember from playing with these gadgets back in the day - I must say, my experiences sent me firmly into the hands of Victron as they do all these things so much better and elegantly and robustly.

Thanks a bunch NiyiOmoIyunade olopan & earthrealm

Actually the DC elements are hidden inside Conext XW+ Conduit Box & Conext + PDP Panel.

In the end, I utilize the attached diagram and the Fronius Primo came to life. This Austrian technology performs wonders.

The project is for a corporate client at Abuja.

Thank you
