Lithium vs Tubular Battery for Solar - My experience after 2 years - Tubular ne dhokha de diya

Assalam o Alaikum Everyone,

I installed 2x Osaka Tubular TR-1800 batteries 2 years ago with my 5kW system. Pehle saal backup 6 hours ka tha, ab sirf 2 hours reh gaya hai.

Shopkeeper keh raha hai ab Lithium lo. Lekin Lithium ki price 3x zyada hai (Rs. 280k vs Rs. 40k).

Jin bhaiyon ne Lithium use ki hai, kya waqai uski life 10 saal hai? Kya maintenance zero hai?

Aur kya ye sach hai ke Tubular 60% hi backup deti hai jabke Lithium 90%?

Please guide, 2 batteries ka 80k zaya ho gaya hai, ab dobara mistake nahi karna chahta.

JazakAllah.

Jinko N-Type 590W price in Lahore - Hall Road quote 27.5/Watt is this okay for August 2026?

Salam everyone,

I went to Hall Road today for 6 panels Jinko N-Type 590W.

One shopkeeper gave me Rs. 27.5 per watt final, another gave Rs. 28.5.

Total for 1 panel around Rs. 16,200.

Is this the current rate in Lahore / Karachi? Has price increased or decreased in August?

Also is Jinko better or Longi HiMo 7?

Thanks.

Knox Hybrid Inverter Help Required Kindly!

I have been using a Knox hybrid inverter 8 kw alongside a 5kw battery. Recently it has been restarting every 3 to 5 minutes and I genuinely can't figure out what is causing this, i've worked around the application settings and changed the BMS cable ports. The inverter does show breathing of BMS. Sometimes it restarts and sometimes it just turns off and we have to manually turn it on and off again. I've been looking for a solar expert but I couldn't seem to get around someone who actually figured out what the issue was and Knox official service center would not accommodate properly under warranty. They don't test it at the site Infront of us and say that it is perfectly fine and that they have done some firmware upgrade but it shows similar behavior when installed at our place. The way Knox service center works is we drop our inverter off they just inform us to take it once they are done and they don't accommodate anything outside it.

We added a UPS so that some of our appliances don't turn off every 3 minutes but our inverter is not letting the ups takeover in that short window causing WiFi and my computer to restart about 200 times a day. The moment we turn off the inverter everything is back to normal.

Inverter model: Knox Xenon 11000 Hybrid Infini WP 8KW ~48V

Battery: Powerwall 6.11 51.2V-100AH Lio 5.32

System Delivering less power than it should?

Hello everyone, we recently got a 8kw Hybrid itel inverter and 5kw itel battery installed with 14x 585W candainSolar solar panels, the panels should be generating 7Kw of energy at maximum and 5-6 KW on an okay-ish day but my system seems to be having a lot of trouble even reaching 3Kw? is this normal? i tried reaching the installers, and they said its a hybrid system, this is how its supposed to function?

one thing to note, our solar panels are divvied up on 2 stand, 7 on each stand, and one of them turned off the breaker on the first day of it running and i turned it back on thinking nothing of it, but now its bugging me, what if that solarpanel group isnt delivering anything?

Is there any way I can check the total power that can be delivered by the solar panels?

UPS vs Inverter+Solar for Lahore Loadshedding: Which Makes More Sense?

Situation: I'm in Lahore dealing with predictable daily loadshedding (typically 1-2 hours). I have a flexible budget and I'm thinking about a backup power solution, but I want something that makes economic sense over 3-5 years, not just a quick fix.

The dilemma: I'm torn between two options:

  1. UPS route — Buy a decent UPS to keep essentials running during outages. Lower upfront cost, simple to set up, minimal maintenance. Downside: I'm replacing batteries every 2-3 years.
  2. Inverter+Solar route — Invest in a 3kW inverter with battery backup + some solar plates. Higher upfront cost, but theoretically pays for itself over time and gives me energy independence. Downside: I'm not sure if it's actually worth it for just 1-2 hours daily, or if I'm overengineering the problem.

My actual questions:

  1. Which option makes more financial sense for someone in Lahore with 1-2 hour predictable loadshedding? Should I think of solar as an investment, or just a quality-of-life upgrade?
  2. If solar is worth it, which Pakistani companies are actually reliable? I see a lot of options online, but I want to know from real experience—who delivers quality without disappearing in 6 months? Any companies to avoid?
  3. Any third option I'm missing? (Like hybrid approaches, or newer tech I haven't heard of?)

I'm looking for real-world experience and honest takes, not sales pitches. What would you do in this situation?

(PS: got help from AI to ask my queestion better)

Has anyone installed wind turbine on their roof?

I know it's a solar subreddit, but I'm just curious, solar has a big problem, doesn't produce electricity at night, and batteries are kinda expensive

So has anyone installed wind or maybe a combination of wind + solar, just in case at night the battery isn't working so maybe the turbine can run a fan

Looking for discussion

Which cities are windy in Pakistan? Islamabad and karachi ?

help in pairing old inverter with itel battery.

i recently bought itel lifep04 battery to pair up with my old ziewnic 4.5kw gold, replacing the old tall tubular batteries.

the problem i face is that the company provided cables are fitted with ring type lugs that are too big to fit into the inverter battery input terminals. what options do i have?

also, is a dc breaker/isolator required between the inverter and the battery like in the old tall tubular setup or is it redundant? the itel manual shows direct connection with the inverter, which is also seen in many installations on youtube but i wanna make sure all the connections are right.

thanks!

Shifted to net billing unfairly? Can anything be done?

Salam,

My friend installed an on grid solar system on his home last year in August, and successfully got a net metering contract (ie, he has the paper document for net metering that describes his system, the net metered connection, and the duration of the contract). Furthermore, his bill clearly states "Your net metering license expiry date is 13/08/2032".

This was all before the net billing thing was even mentioned. Unfortunately, his MCO got delayed internally in IESCO (which I know happens sometimes). As far as we understand things, when the government tried to introduce net billing, they froze processing of all documents for a while. So, his MCO was stuck. Despite having an AMI meter, the bill only showed a single reading.

He complained to IESCO a few times, directly, as well as through his solar installer. Eventually the MCO went through roughly a couple of weeks ago. They've adjusted the bill based on the export of units over the last year (his connection is 1 year old), but it seems to be on the basis of net billing, since he received roughly Rs. 8.xx for each exported unit.

The problem is that his bill under "Category" says net billing, and at the same time, lower down, mentions "Your net metering license expiry date is 13/08/2032". He also has the official contract for net metering. What should he do now? Is there any chance to get this fixed to a net metered connection?

Thank you!

You can see under \"Category\" it says Net billing. This has appeared for the first time this month

Here it says you have a net meter license. This has appeared for several months, ever since the bill format got changed

Custom: Roof Solar Structure

Disclaimer: Just sharing a DIY engineering project my dad and I recently finished to get feedback and show off the setup.

---------------

We built this entirely from scratch by hand. My dad and I designed and fabricated the mounting frame ourselves because hiring contractors was way out of our budget, and modular frames like this aren't really available off the shelf locally anyway.

-----------------------------

While the frame might look lightweight, it relies on classic bridge-building principles. We went with a triangular truss layout to distribute the weight evenly, maximize rigidity, and keep everything rock-solid against strong wind loads in Karachi.

-----------------------------------------

The best part is that it's 100% modular and relocatable. The entire structure is bolted together, with the legs anchored into small, localized concrete footings. Whenever we move, we can just break the small concrete pads, unbolt the frame, and take the whole setup with us without damaging the roof or the frame.

I have On-Grid Solar setup and looking for load shedding solution.

Most of the year its fine but sometimes load shedding is too much, straight 7-8 hours especially all night, what is the solution for that, i have currently UPS & Batteries that give like max 3 hours backup, what is the best economical solution, i don't want to spend too much on new inverter or batteries, something nice, affordable and smaller in size but works long term?

Sungrow Batteries

I have a Sungrow SH10RT hybrid inverter with an existing SBR battery. I'm looking to expand the battery and am trying to find a SBR battery.

The newer SBH100/150/200/etc. batteries are available from local suppliers here, but I understand they are not compatible with my SH10RT, so I'm specifically looking for the SBR series.

Does anyone know:

- Is the SBR160 still being manufactured/available?

- Where can I buy one, preferably new?

- Any idea about price?

Advice on Expanding Hybrid Setup

Looking for advice on expanding my Sungrow solar setup

I currently have a 10 kW Sungrow SH10RT hybrid inverter with a 16 kWh battery, and I'm looking to expand the system. I'm considering three options:

  1. Add another hybrid system

    Can I add a hybrid inverter from a different manufacturer, or would it be better/necessary to stick with Sungrow?

  2. Add more batteries to my existing system

    Sungrow has released newer battery models, and I'm not sure whether they are compatible with my older SH10RT setup. The downside is that I can't add more PV on this inverter, so not really ideal. Has anyone successfully mixed/expanded batteries on an older Sungrow system?

  3. Add an on-grid inverter in parallel

    This seems like the cheapest option, especially if I add another ~10 kW of panels. However, I'm concerned about the current/future government net-metering/net-billing policies and whether adding an on-grid inverter makes financial sense.

I'd appreciate advice from anyone who has expanded a similar setup. What would you recommend, and what are the pros/cons of each option? I'm particularly interested in long-term reliability, battery compatibility, backup capability, and ROI under the current Pakistani electricity/net-billing situation.

Lastly, do I need to get further approvals from KE of I expand my setup?

Need helpppp

Recently bought a 6kw system from an official inverex distributor here in rwp, The seller sold me inverex "multi power" solar panels (620w). The panels themselves have no inverex branding on them, the only mention of inverex is on the warranty card that too in the group of companies section. The seller insists that theyre inverex panels but i cant verify it. The panels themselves have no qr codes on em ( bar codes are present but idk what to do with em).
