What these specifications mean

Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20 is listed with 5 published specifications from Knox, including design of 10 years, battery type of LiFePO₄ (Lithium Iron Phosphate), cycle life of Over 6000 cycles and total energy of 10.24kWh. 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.

What people get wrong

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

No price is published for Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20 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 your country: warranty cover on solar hardware is normally honoured through the channel you bought from, so confirm who supports Knox locally before ordering.

Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20 — frequently asked questions

What are the specifications of Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20?

We hold 5 published specifications for this battery, including design 10 years, battery type LiFePO₄ (Lithium Iron Phosphate), cycle life Over 6000 cycles, total energy 10.24kWh and voltage 51.2V, 200Ah. The full table is on this page, listed under model KNOX-82.

Who makes Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20?

Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20 is a Knox product, listed under batteries with model reference KNOX-82. The Knox brand page lists the rest of its range so you can compare across the catalogue.

Is Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20 right for my system?

That depends on what it has to connect to. For a battery, check nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh), usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50% and system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack against the rest of your equipment before price enters the decision. 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.

Where can I buy Knox Rackwall 10.5 Lithium-ion Battery with Touch LCD Display - 51.2V 200AH IP20?

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 — buying in-channel is what keeps the manufacturer's warranty valid.
