What is the difference between On-Grid, Off-Grid, and Hybrid inverters?
Each inverter type serves a distinct power need:
On-Grid (Grid-Tied): Works directly with the solar panels and WAPDA/K-Electric grid. Ideal for Net-Metering to export units. It turns off during loadshedding for safety.
Off-Grid: Operates strictly with battery storage and solar panels, completely detached from the grid. Perfect for remote farmhouses and rural areas.
Hybrid Inverters (Most Popular in Pakistan): The best of both worlds! They power your home with solar, charge your lithium/tubular battery for backup, export excess electricity to the grid via Net Metering, and switch seamlessly in under 10 milliseconds during loadshedding.
Can Knox, Growatt, and GoodWe hybrid inverters run without a battery?
Yes! Most modern Tier-1 hybrid inverters in our store (such as Knox Krypton Eco/9000, Growatt SPF 6000 ES Plus, and GoodWe ET Series) support battery-less operation during daytime.
They can power your home loads directly from solar generation and export any surplus to the grid. However, to maintain power uninterrupted during nighttime loadshedding or grid outages, connecting a lithium or tubular battery is recommended.
Which inverter size is needed to run a 1.5 Ton Inverter AC?
A standard 1.5 Ton DC Inverter AC consumes approximately 1,400 to 1,800 Watts during initial compressor start and stabilizes around 800 to 1,200 Watts .
A 4kW or 6kW Hybrid Inverter (such as the Knox Krypton 6kW or Growatt SPF 6000) can comfortably run one 1.5 Ton AC alongside your refrigerator, ceiling fans, LED lights, and TV. For running two 1.5 Ton ACs simultaneously, an 8kW to 12kW inverter (like the GoodWe GW12K 3-Phase) is recommended.
How many units (kWh) will a 6kW solar system generate per day in Pakistan?
Pakistan has one of the world's best solar irradiance levels, averaging 4.5 to 5.5 peak sun hours daily.
A properly installed 6kW solar system with Tier-1 bifacial panels will generate between 24 to 32 units (kWh) per day during summer and spring, and approximately 18 to 24 units per day during winter months. Over a year, this generates around 750 to 900 units per month on your electric bill.
Why choose Lithium Iron Phosphate (LiFePO4) over tubular lead-acid batteries?
While lithium batteries have a higher initial purchase price, they are substantially cheaper over their lifespan:
Lifespan: LiFePO4 batteries last 10 to 15 years (6,000+ deep cycles) compared to tubular batteries which degrade after 2 to 3 years (800 cycles).
Usable Capacity (DoD): Lithium delivers 90% to 95% usable depth of discharge without damage, whereas lead-acid can only safely discharge 50%.
Zero Maintenance: No distilled water refilling, no acid fumes, no dangerous corrosion, and wall-mountable space savings.
Fast Charging: Fully charges in 1.5 to 2 hours from solar compared to 8–10 hours for lead-acid.
How many hours of backup does a 5.12 kWh or 10.5 kWh battery provide?
Backup time depends strictly on your running electrical load:
At typical night load (400W — 4 Fans, 8 LED lights, 1 TV, 1 Wi-Fi router): A 5.12 kWh battery provides 10 to 12 hours of continuous backup .
With a 1.5 Ton Inverter AC running on eco-mode (1,000W total load): A 5.12 kWh battery provides approximately 4 to 5 hours , while a 10.5 kWh RackWall battery provides 9 to 11 hours .
Can I add more battery modules in the future to expand storage?
Yes! All lithium storage systems we sell (including Growatt, Knox, and RackWall) feature modular parallel expansion ports. You can start with a single 5.12 kWh unit and parallel up to 15 additional units as your energy needs expand, without modifying your inverter wiring.
How can I track my order without logging in?
You can track any order instantly on our dedicated Track Order Page . Simply enter your Order ID (e.g. MI-1F5TEX ) received on your invoice or confirmation message. No password or user account is required.

Are your products 100% genuine with official brand warranty?
We are an official Knox distributor and a sub-dealer for selected brands including Itel, Growatt, Pylontech and GoodWe. Confirm the exact model, supply channel, invoice and any serial-number verification offered by the manufacturer before purchase. Warranty coverage depends on the exact product and written terms; eligible claims are assessed by the relevant company or authorised service centre. Direct-import items do not carry a separate store warranty unless stated in writing. See our warranty policy for details.
How does the warranty claim process work?
In the rare event of a hardware issue:
Check your error code with our support team on WhatsApp ( 0300 1234567 ). Many issues are resolved instantly via software configuration or breaker resets.
If hardware diagnosis is required, present your purchase invoice or serial number.
Your hardware is serviced or replaced by the authorized brand center under official warranty terms.
What are the requirements for WAPDA / LESCO / K-Electric Net-Metering?
To qualify for three-phase bidirectional green net-metering in Pakistan, you need:
A sanctioned 3-Phase electricity connection from your DISCO (LESCO, GEPCO, FESCO, K-Electric, etc.).
An AEDB-approved / certified Three-Phase Inverter (e.g. GoodWe GW12K, Knox Krypton 3-Phase).
A certified Tier-1 electrical installation scheme and three-phase bidirectional green meter installation.
Our team can connect you with certified installer partners to handle the end-to-end documentation and NOC approvals.
How much can I reduce my electricity bills with solar?
With current protected and unprotected electricity tariffs in Pakistan ranging from Rs. 45 to Rs. 70+ per unit (including fuel adjustment, taxes, and surcharges), an optimal 6kW to 10kW solar system typically slashes electricity bills by 75% to 95% .
Most households recover their entire capital investment within 2.5 to 3.5 years , after which electricity is virtually free for the remaining 20+ year life of the panels.
