What these specifications mean
Knox H-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah is listed with 12 published specifications from Knox, including battery capacity of 52Ah, battery voltage of 48Vdc, cell technology of LiFePO4 and charge temperature range of 0~ 50°C. 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 round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid, communication protocol (CAN or RS485) for talking to the inverter, nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh) and usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%. 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.
What to check before ordering
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.
- Size from your evening consumption. Add up what actually runs after sunset for the hours you want covered, then divide by the usable capacity per unit — that number, not the array size, sets how many batteries you need.
- Check the continuous discharge rating against your inverter. A battery that stores plenty of energy but can only deliver 50 A cannot support a large inverter at full output.
- 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.
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
No price is published for Knox H-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah 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 H-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah — frequently asked questions
What are the specifications of Knox H-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah?
We hold 12 published specifications for this battery, including battery capacity 52Ah, battery voltage 48Vdc, cell technology LiFePO4, charge temperature range 0~ 50°C and communication CAN, RS485. The full table is on this page, listed under model KNOX-17.
Who makes Knox H-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah?
Knox H-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah is a Knox product, listed under batteries with model reference KNOX-17. The Knox brand page lists the rest of its range so you can compare across the catalogue.
Is Knox H-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah right for my system?
That depends on what it has to connect to. For a battery, check usable capacity after depth of discharge — LiFePO4 typically allows 80–100%, lead-acid closer to 50%, system voltage: 12 V, 24 V and 48 V for low-voltage packs, or a high-voltage stack and continuous charge and discharge current, which limits how much power you can draw from the pack 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-U4850G 2.5kWh Lithium-Ion Phosphates Battery 48V 52Ah?
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.
