Luminous has an 'i' variant of the Zelio now. I cannot understand why this variant even exists. From what i can tell it has the same features as the wifi model except, it does not work with wifi but instead uses bluetooth. This limits the range and seems like a regressive step.


Was it so difficult to get the wifi model working that they opted after to release a bluetooth version instead :rolleyes::banghead:
So did you buy this ?
if yes,then review would be great.

No, will mostly likely be the Flinn once i figure out venting. Why is it taking so long ? because there is a learning curve

The advantage is it can handle a load of 3kW so i could use it for two floors in the future if required. Play with solar too. The second floor isn't given for now but its an option in the future if the need arises.

I wish Flin offered a model that allowed to configure between two & four battery systems instead of forcing to buy either a two battery or four battery inverter model.

Made another batch of clear ice and melted it. Ended up about a litre. This time i took care to let the ice melt a bit so as to reduce any contamination with cloudy ice. It's easy, just let it sit out and shave away towards the clear part. Rinsed out the container it would melt in as well and hit zero TDS :cool:

20190812_021517.jpg20190812_211701.jpg

What is zero TDS and did i really make zero TDS water ? well, not quite. Technically, zero TDS means water with a conductivity of 0.05 micro siemens. This is ultra pure water. So what is the conductivity of my water.

20190817_175559.jpg

2.1 micro siemens. So zero TDS is 42 times purer.

And what about the TDS

20190817_175908.jpg

0.9 TDS

This meter has more resolution, adds a decimal point. The cheaper ones round down anything that is less that 1.00 TDS as zero. They do whole numbers only so aren't sensitive enough below 1 TDS.

I tested the total hardness in CaCO3 and it worked out to 1mg/L or 1ppm.

Starting from aquaguard water of TDS 145 and total hardness somewhere between 125-150 mg/L (ppm) of total hardness down to 0.9 TDS and 1mg/L total hardness. This is pretty good for a home effort i'd say.

I went looking for distilled water again and picked up a 1L & 5L from an Indian Oil petrol bunk. Last attempt from BP petrol bunk was a reject, so will this brand be better ?

20190817_181002.jpg20190817_181115.jpg20190817_181141.jpg.tmp.jpg20190817_181313.jpg

Looking at the label, this Indian chemical company shows more info. Says they've been in the business since 1988, that's got to count for something.

Not only is there a manufacture date, there is also a best before date. Unlike the last product, this company states their water is only good for a year from manufacture. They also state their water is zero TDS and de-mineralised. No idea what free "chlofine" is, chlorine maybe, but i'd have liked to have seen nil for chlorides. No idea what unit they are using when they say less than 20. If there are any Chlorides then should get picked up by the meter as they will increase TDS. Chlorides should not exceed 5 ppm or there will be loss of capacity in both plates with the positive losing more.

max allowable impurities.jpg

They state the electrical conductivity is 4 micro ohm/cm which is the incorrect unit for conductivity. Conductivity is not expressed in ohms/cm but siemens/cm. Resistance is expressed in ohms. Since 4 mico ohms is mighty low it must be 4 micro siemens. Purer water has higher resistivity and is the reciprocal of conductivity. So how does this one test out ?

20190817_180455.jpg20190817_180601.jpg20190817_180718.jpg

TDS 1 says the AP-1, actually its 1.4 says the other. So any TDS under 1.5 i'm guessing gets rounded down to 1 on the AP-1. The conductance is 3.1 uS so that is within spec. The total hardness is zero.

Compared to the last bottle i got this one is way better.

It has less hardness than my clear ice sample but i got it beat for TDS & conductivity.

Conductivity seems a more sensitive way to measure water purity than TDS at near zero TDS.

EC is the norm in the EU. The Americans use TDS and complicate things. TDS can use different standards, 442, NaCl & KCl. Unless the specific std is mentioned a TDS count is meaningless. EC is simpler and does not depend on anything else. TDS is EC times some factor.

The setting of 0.5 refers to NaCl standard. If a TDS meter goes up to 5000 ppm like the AP-1 then its using the NaCl standard which has a 0.5 conversion factor between conductivity & TDS. With HM meters conductivity is roughly twice TDS.

Is there a correlation between TDS & hardness? Samples i've tested show a close correlation until they don't. Last sample of distilled water i got had a TDS of 23 but total hardness was 2 mg/L. So TDS & Hardness are not always fully equivalent. There could be other things in the water contributing to TDS but not coming from hardness.

Still on the lookout for Exide distillo, no exide care nearby had it.

Want to try deionised water as well if it can be had at a decent price.

Can you provide any specifics? I was thinking of buying the Zelio+ 1100 without Wifi.
See posts #34 through #39 in this thread. I have given up waiting for that damn OTP. The non WiFi version might be OK.

I wish the maintenance free batteries will last that long. Even single digit deep cycles is enough to have a impact on battery life and their life more so depends on ambient temperature, works best for climate controlled rooms.
Exide Solartron Data sheet.pdf

Catalog says it can handle frequent deep cycles and its less sensitive to temperature changes. Check these graphs out for Solartron

Solartron cycle life.jpg



Over a thousand cycles at 80% discharge. My staircase room is as climate controlled as it gets. No more than 2-3 degrees variance between day & night.

Highest i saw it go was 32 degrees C this May. This May was very hot.

Question is how much more hot will this staircase room get with the Flinn in there. Whether I need to install an extractor fan during the hot months ?

A vent on the door and an extractor fan higher up on the opposite wall running on a timer for 12h during the hot months.



Solartron discharge rate.jpg



And to figure out how to program the Flinn to these specs.

Imagine 2 x 200 AH's worth is going to be pricey. Probably more without exchange of an older battery of similar specs.

Let's see what their warranty terms are like.

No solar panel attached ? no warranty ? or what

The interesting thing is comparing the weight of the EL 200 AH to the Solartron 200 AH

Exide EL.PNG

Calculating volume for the two batteries. The Solartron has more depth. 10cm more. Making the volume for the 200 AH 30% larger than the equivalent EL 200 AH

The EL weighs 76 kg, the solartron at 84 kg

Gel is more dense than acid.

solartron 200AH weight.jpg

Above is from an older catalog showed the solartron 200 AH at 72 kg. Whether that was a typo

That exide Solatron does have good spec but I still not convinced, may be it can last that long, Luminous 60 month warranty solar tubular battery advertise as 1500 cycles despite weighing less then exide 6LMSL series which have advertised as 1200 cycles. But I am sure the flooder batteries will out last the gel batteries. Mobile towers, railways still use flooded 2v tubular batteries no one uses gel batteries.
They are also like 30 % more expensive then 6LMS series.

Flin will be venting hot air at heavy load but if there is a high enough ceiling and if let the door open under your stair case area, then it should rise up along with H2.

Flin as settings for low voltage cut off, so if the battery voltage drops below the set parameter it can either switch to Mains power or shutdown the output if their is No mains or solar.
It will also take into consideration the load connected when displaying the battery state of charge, it has a rough idea that the lower battery voltage is due to heavy load vs the low battery voltage with minimal load.This is only for the display. When the voltage goes to 21v to 24v or 42v to 48v user configurable for 2 or 4 battery system respectively, it will shut down the output or switch to Mains.

Update: So I had kept 80k aside for the 4 x 200ah tubular batteries which where my last choice, Idealy would like lithium batteries but they are still too expensive. Since there was practically no power cuts. I went and put a 200L solar water heater and a pressure boosting Pump and a 60Liter pressure tank, all totaling about 1lakh or so with zero labor, all plumbing connections where done by me and my dad. I broke a finger in the process.
No longer need to wait for geyser to heat up after some one else takes a bath and off course the reduced power bill. Also because of pressure boosting pump, I can use aerators will 1l to 3l min water flow, thus also saving water, compared to the earlier 10 to 15l/ min water flow.

While the lonely Flin is mounted with all connections made including a self made marine plywood battery box, minus the battery and solar panels.

Was trying to procure Lifep04 bare cells, some advertised as BIS certified, If I make my own battery pack they work out about 60% more expensive then exide 6lms, including BMS boards for each cell in series, the data sheet the indian sellers provide is basically cut copy paste from Chinese sellers. So not really sure about the cycle life claims.But Just thinking about no fans or maintenance makes me won't to plunge but need more proof about the cycle life, worst case is that they match the exide cycle life.

Exide NXT cycle life.jpg


The NXT series are gel but the cycles in a online ups environment are less. 400 - 700 at 80% DoD

Now the Solar 6LMS series gets much more

ceil-solar-cycles.jpg


Let's compare with the Solatron

Solartron cycle life.jpg


Looks very similar doesn't it. In fact the 20% discharge on the solatron beats the flooded one

Let's see what deep cycle gel batteries from other companies can deliver

Trojan AGM Solar

Trojan solar AGM cycle life.jpg


The NXT are AGM but i don't think the solartron are AGM, they are just Gel. But this Trojan seems to deliver 1000 cycles at 80% DoD. Here's the kicker, their 200 AH C20 weighs only 59 kg (!)

What about Trojans deep cycle Gel batteries ?

Trojan deep cycle gel cycle life.jpg


This one only gets half as many cycles for some reason. Here their 12 V 200 AH weighs 76 kg which is closer to the Solartron's weight. Hmm

Are we to believe exide india which has nothing to do with Exide US has the best gel based lead acid battery out there. Neverthless its 30% more expensive closer to Lifep04 prices.
Gel based ones have a big if one its cycle life because of the temperature factor, they do feel warmer to touch compared to flooded ones.

Solatron capacity is calculated when discharged to 1.75v/cell where as 6LMS capacity is discharged to 1.8v/cell big difference( less if calculated as per BIS13369), you can see the exide powesafe 1.8v vs 1.7v runtime @ 600min is c10 the date is in constant power as in watts, which is V*A.

Why not ? this isn't rocket science. Gel batteries came out in the 70s. Exide has partnerships with other companies. Fifty years later India has surely caught up. Exide is more credible than Luminous.

Another powersafe battery for online UPS, this is the XHD tubular gel which seems similar to the solatron. But the max size is only 165 AH whose weight is similar to the Solatron 150 AH

Exide XHD tubular-powersafe_cycle life.jpg

Here the 80% DoD is 600 - 1000 cycles compared to fewer for the NXT range

Exide NXT cycle life.jpg


The difference with XHD is torr tubes. Why that increases cycle life i'm not sure.

The point here is if an online UPS VRLA battery can touch a 1000 cycles then why is it so hard to believe a similar good quality solar VRLA battery in an offline UPS application cannot do it :)

There is no reason a well constructed VRLA battery cannot match a flooded battery if temperatures are not too high. If there is careful charging with no over charging. So if the operating temps is 40 degrees C then flooded is the better choice. But closer to 30 the comparison could be more evenly matched.


What has me bothered is the float service life. First the NXT


Exide NXT-powersafe_float service life.jpg


About 2.5 to just under 4 years at 30 degrees C

And next is the XHD

Exide XHD tubular-powersafe_float cycle life.jpg



What does this mean ? if battery is stored around the 30 degree C mark its useful life is between 3 - 5 years ??

Forget cycle count, if there is a hard limit built here in terms of life the thing dies before you even get to fully cycle it !!

Why does only the VRLA online series publish float life info and not the solar VRLA.....

From your experience with the APC Smart UPS which is an online UPS, no brainer choice is to go with the flooded EL series and not any VRLA

But does that hold true for offline UPS which is my use case. Flin is not an online UPS. The stress it puts on the battery will be less.

My apc smart ups is not On line but rather its line interactive. I see no reason as to why online or offline ups have anything to do with battery life.
The charge circuitry principal is the same, the smart ups has ability to control the battery voltage and higher quality components vs a typical home inverter.

Online ups AC voltage is more constant because of the dc to ac conversion, so there will be no delay during mains fails and constant output voltage.
Line interactive models stabilze the voltage from mains and also the inverted AC (via battery). But for battery life, I can say that Flin charging circuity is as good as a online ups, minus the battery temperature sensor. I dont think apc Online Ups have that much control over the battery settings.

I think exide markets them differently because lets face it, the local inverters sold in India have some crappy internal designs with huge tolerances. People still buy square wave inverters. I have seen inverters with luminous, microtek casing but with local internal circuits. So exide takes all of those into account for warranty.

Many battery companies in India, give more warranty for solar use, additionaly exide does so for Online ups. Only think I can get from this is that in these two usage scenario the batteries are cycled more often, solar cycles daily. Online and line interactive cycles only during power cut or abnormal voltage vs offline ups only during power fail, but they also have ups mode switch.

We have indoor tempertures of 34c last summer, so vrla is no good. Without active climate control, there is now way we can maintain the temperature at 27c or less.

This is tangentially related but things will be looking up for Flin and other made in Taiwan products if this commentator has it right.

China no longer retains a language advantage as most young Taiwanese can speak english these days.

The human material available in India is on a scale and of a quality that any global company would be hard pressed to find elsewhere. For the first time, there has been a sharp acceleration in the interest and investment of Taiwanese companies in India, with the levels of both in 2018 being greater than the total of the previous 51 years. Excellent leadership at both the India mission in Taipei as well as the Taiwan mission in Delhi has played a keystone role in such a development, as has the momentum given by Prime Minister Narendra Modi to the Make in India process. Building on this, a quantum leap needs to get made, such that Taiwanese investment in India gets across the $20 billion mark within two years and $50 billion by 2024.
An advanced Research & Development facility could be set up in Haryana within driving distance of the international airport. Production facilities by Original Equipment Manufacturers would need to be set up near ports, in view of the economies in costs of shipping finished products rather than getting ferried by air. While an R&D facility may be smaller, parks designed for production of components need to be on a substantial scale, as close to 10,000 acres as is feasible in Indian conditions.
This is how the Made in India Lithum batteries will become available.
