Most-installed residential battery in Pakistan. 10-year warranty. DL Series (5–10 kWh) and PowerBrick MAX (16 kWh). Local warranty support.
View Dyness range ›Global leader in residential battery storage. Fidus 5 kWh and Fidus Plus 16 kWh. 10-year warranty. Widely used with Solis inverters.
View Pylontech range ›Most affordable LiFePO4 option in Pakistan. Strong nationwide service network (22 centers). 5-year warranty. Best where price is the priority.
View KNOX range ›10-year warranty included. Pairs seamlessly with FoxESS hybrid inverters. Growing service network in Pakistan. ECS series modular storage.
View FoxESS range ›Battery price scales almost linearly with kWh capacity. A 10 kWh unit costs roughly 1.7–1.9× a 5 kWh unit from the same brand — not exactly 2× because the BMS, casing, and connectors are shared costs. The 5 kWh size is the most price-competitive entry point.
Dyness and Pylontech carry 10-year warranties; KNOX carries 5 years. The 10-year warranty brands cost Rs. 5,000–15,000 more per unit. Over a system's 20-year life, warranty coverage significantly affects total cost of ownership — one warranty replacement claim pays back the premium many times over.
This price guide covers only LV (48V/51V) residential batteries — the type that pairs with standard hybrid inverters (Solis, GoodWe, FoxESS). High-voltage (HV) battery systems for industrial BESS applications cost Rs. 800,000–5,000,000+ per unit and are a completely different product class.
Premium brands include advanced Battery Management Systems (BMS) that actively balance cells, prevent over-charge/over-discharge, and manage temperature. This directly affects how many charge cycles (and therefore how many years) the battery lasts. Dyness and Pylontech are rated 6,000–8,000 cycles at 80% DoD — roughly 16–22 years at one cycle/day.
The right battery size depends on your daily load shedding hours and which appliances you want to run during outages. LiFePO4 batteries are rated at 80–90% Depth of Discharge (DoD) — the usable portion of capacity.
| Backup Goal | What Runs | Recommended Storage | Typical System |
|---|---|---|---|
| Basic backup (4–6 hrs) | Fans, lights, router, TV | 5 kWh | Any 6 kW hybrid system |
| AC backup (2–4 hrs 1-ton AC) | 1 ton AC + basic loads | 10 kWh | 6–8 kW system + 2×5kWh |
| Full night backup | All evening/night loads | 16 kWh | 8–10 kW system + 16kWh unit |
| Heavy load / factory UPS | Industrial critical loads | HV BESS | Contact us for quote |
Rule of thumb: (hourly load in kWh) × (backup hours) ÷ 0.85 = battery capacity needed. Use our solar calculator for a precise estimate based on your actual appliances.
LiFePO4 (lithium iron phosphate) batteries cost 3–4× more upfront than equivalent lead-acid batteries, but the total cost of ownership over 10 years is significantly lower.
| Factor | LiFePO4 (Dyness/Pylontech) | Lead-Acid (AGM/Gel) |
|---|---|---|
| Cycle life | 6,000–8,000 cycles | 300–500 cycles |
| Usable capacity (DoD) | 80–90% | 40–50% |
| Charge speed | 1–2 hrs (0.5C rate) | 8–12 hrs |
| Maintenance | Zero maintenance | Water top-ups, terminal cleaning |
| Weight per kWh | ~7 kg/kWh | ~25 kg/kWh |
| Warranty | 10 years | 1–2 years |
| Replacement in 10 yrs | None needed | Replace 8–10 times |
| Works with hybrid inverter | Yes (designed for it) | Limited compatibility |
The battery is typically 10–20% of a complete installed solar system. Here is how battery storage adds to a base system cost:
