Reading the specifications
Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery is listed with 6 published specifications from Knox, including battery voltage of 51.2, capacity of 102 Ah, cycle life of 8000+ and type of Lithium Iron Phosphate Battery. Those figures are what decide whether this unit fits your system, so read them against the equipment it will connect to before comparing price.
For a battery, the figures that matter most are system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack, cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 and round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid. Storage is what turns a solar array from a daytime bill-reducer into a system that covers evening loads and rides through outages. It is normally the single most expensive component, so sizing it correctly matters more than with any other part.
Before you buy a battery
The checks below apply to any battery. Run them against the specification table above — most disappointing solar purchases are compatible-on-paper units that fail one of these in practice.
- Match voltage to the inverter, and confirm the battery appears on the inverter maker's supported list. Closed-loop communication lets the inverter respect the battery's real charge limits instead of guessing.
- Read the warranty in full: lithium warranties are stated as a term plus either a cycle count or a total energy throughput, and whichever limit arrives first ends the cover.
- Leave room to expand. Packs that parallel cleanly let you add capacity later; ones that do not force a full replacement.
- Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
Common mistakes
- Mixing old and new batteries, or different chemistries, in one bank. The weakest unit drags the whole bank down and can be damaged by the others.
- Sizing the bank for total daily consumption rather than after-dark consumption, which typically doubles the cost for no benefit.
- Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.
Price and availability in Pakistan
No price is published for Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery in Pakistan at the moment. Pricing on solar equipment moves with supply and exchange rates, and some distributors quote only on request — the specifications above are still directly comparable against alternatives that do list a price.
SolarBazaar compares equipment rather than selling it. Shortlist here on specification and price, then buy from an authorised distributor or installer in Pakistan: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Knox locally before ordering.
Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery — frequently asked questions
What are the specifications of Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery?
We hold 6 published specifications for this battery, including battery voltage 51.2, capacity 102 Ah, cycle life 8000+, type Lithium Iron Phosphate Battery and weight 48Kg. The full table is on this page, listed under model KNOX-29.
Who makes Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery?
Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery is a Knox product, listed under batteries with model reference KNOX-29. The Knox brand page lists the rest of its range so you can compare across the catalogue.
Is Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery right for my system?
That depends on what it has to connect to. For a battery, check system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack, continuous charge and discharge current, which limits how much power you can draw from the pack and cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4 against the rest of your equipment before price enters the decision. Compare usable kilowatt-hours, not nameplate capacity. A 100 Ah lead-acid battery at 12 V is nominally 1.2 kWh but only about 0.6 kWh is safely usable, while a 100 Ah LiFePO4 pack gives you roughly 1.0–1.2 kWh.
Where can I buy Knox H-U51100 51.2V 102Ah 5.2kWh Lithium Ion Phosphate Battery in Pakistan?
SolarBazaar lists and compares equipment rather than selling it. Use the specifications and price here to shortlist, then buy through an authorised distributor or installer in Pakistan — buying in-channel is what keeps the manufacturer's warranty valid.
