Everybody is talking E-bikes, but nobody is talking about:
- Resale value
- Battery replacement costs
- Toy-like looks (not for men)
- Poor body materials
In Pakistan, we need a workhorse, not a gadget. What’s the #1 thing stopping you from buying one? 🇵🇰🏍️

@qaisarnadeeem Spot on. HV bats skip the boost converter stage inside hybrid inverters. PV string at ~400V DC → bat at ~400V DC = near 1:1 coupling. No step-up, no extra MOSFET losses. dat's where d real round-trip efficiency gain (~96–98%) comes from. LV sys lose 3–5% just on the DC-DC stage
English
If U don't know the difference: LV 🔋systems typically operate around 48–51.2V,while HV systems range roughly from 150V up to 600–800V, depending on how stacked module size. HV batteries run at similar DC levels as solar panel strings, which means lower current for the same power
English
For solar installations requiring over 25kWh of energy storage, it’s time to move past Low Voltage inverters& batteries.Instead,opt for a High Voltage system.The pricing gap has largely vanished & HV technology offers superior efficiency,easier modular scaling & lower heat losses

Would someone please raise the voice against the extortion by DISCOs' staff who may "charge" Rs 100 k for meter installation? That is what they have been doing for years. NEPRA needs to audit why the meter installations were delayed after the approvals.

I’ve spent over two decades studying the Pakistani state. But words fail to describe how malevolent, low-IQ, & beholden to vested interests, the administration is. The people trying to stop solar power adoption in Pakistan are all university educated professionals. Check their CVs and you will find many with foreign qualifications & fancy fellowships. When they retire some will produce silly self-exonerating memoirs. And while they were in government for decades two questions never occurred to them: 1. What is in the national interest and public interest of Pakistan? 2. How can we help Pakistan achieve these constructive objectives? At a time of global energy crisis, Pakistan needs to move even more rapidly towards solarisation. Instead, the administration is trying to impede solarisation and now they are going after not just the ‘bourgeoisie’ or ‘rich’ solar net metering folks, but others as well.

Anyone into coding or building side projects rn?
Share what you’re working on. I’ll invite active people to a small tech discussion group.

@smartpsx_pk @Nasir_dar101 @WealthWise15992 @MeherJazibAli @FireThroughPSX @4ValueInvestor @qaisarnadeeem was missed from list.
English
I like @WealthWise15992 @MeherJazibAli @FireThroughPSX @4ValueInvestor myself, and many others I'm not recalling abhi
Also (shameless plug 😅), investors can check out SmartPSX as a tool for smart automated portfolio tracking too, think Investify but better 😄
Check out smartpsx.com or play.google.com/store/apps/det…. iOS coming soon IA.

Hello PSX community on X.
Which Twitter Accounts you think, are genuinely helping the Trading/investing PSX community on X ?
(Apart from my own)
I know, you know there are many Rats, (not only in psx)
But we are not discussing here.
Only genuine and sincere ones.
Plz mention if you know some, thanks.

@qaisarnadeeem @motasim or maybe take iron back to Itifaq foundry;)
English
@AliNasir031 @motasim they worry about 500 KM/hr Wind , which would take away fiber sheet anyway 😀
English
Why is Lahore Metro installing such heavy iron structures just to cover stairs with fiber sheets? 🤔 Isn’t this over-engineering and wasting taxpayer money? any material/structural engineer explain if this much iron is really needed, or would a simpler design suffice? #LahoreMetr
English
@motasim @qaisarnadeeem bhai need your thoughts on this
English
Question for engineers: Is ~150 tons of iron really justified for rain covers, or is this over-engineering at taxpayer expense? Could lighter, simpler designs work? #Engineering #PublicFunds
English
Weight estimate: iron tubing ~3.5 kg/ft.
42,768 ft × 3.5 kg = ~150,000 kg (150 tons) of iron.
All this to hold fiber sheets against rain. 🤯 #LahoreMetro
English
Do the math:
3564 arches × 12 ft = 42,768 ft of iron.
That’s more than 8 miles of iron framing just for stair covers. #TaxMoney
English
Each pedestrian bridge has 33 arches, each 12 ft long. With 4 bridges per stop × 27 stops, that’s 3564 arches total across Lahore Metro. #PublicFunds
English
Another outage. So 55 minutes of supply in 4 hours.
Motasim Bajwa@motasim
No light from 8:15 to 9:15. From 9:30 till now theres no light. Only 15 minutes supply in two hours and 6 minutes.

@sulemaniya_ @motasim @TalhaEjaz07ee Yes, ap ka 13kVA diesel generator ko fully replace nahi krna padega, balki hum ise hybrid system mein smart bkup bana sakte hain. Genrator ko sirf tab chlana hai jab battery low ho, baqi time batteries + inverter se ACs chalenge. Yeh diesel kharcha bohot kam kar deta hai 50-80%
Indonesia
@TalhaEjaz07ee I have a Diesel fired generator which is heavy duty can one make it work on Lithium batteries? And at this time don’t have any solar panels so if want a system which would make my own electricity what’s the best way to go around it? And what cost would be incurred? Generator is 13kVa and utilisation is also around 2-3 ACs but they don’t run round the clock.
English
The best investment. Not only saves money, saves you a lot of frustration as well. And that is the most important part.
Talha Ejaz@TalhaEjaz07ee
You can go 100% off grid in 2 million. With two 1.5 ton ACs running almost round the clock.

@arshad_finance @TalhaEjaz07ee Please can you guide me the cost of the whole system and the relevant person in Karachi

@TalhaEjaz07ee @NaumanJps Sir 1 million main 32 unit nahi aatay.
Fox is 6.8 for 12 units. Dyness is 7.5 for 15 units.
