How to read this datasheet
Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series is listed with 9 published specifications from Phoenix, including life cycle of 5,000 cycles, nominal voltage of 51.2 V, battery capacity of 105 Ah and battery chemistry of Lithium Iron Phosphate (LiFePO4). 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 cycle life at a stated depth of discharge, commonly 3,000–6,000 cycles for LiFePO4, round-trip efficiency, around 90–95% for lithium and 75–85% for lead-acid, communication protocol (CAN or RS485) for talking to the inverter and nominal capacity in ampere-hours (Ah) or kilowatt-hours (kWh). 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.
Where buyers lose money
- Installing lithium packs in an unventilated, hot enclosure. Sustained high temperature is the fastest way to lose cycle life.
- Ignoring the charge current limit and pairing a large array with a small bank, which trips protection and shortens life.
- 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.
Price and availability
Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series is listed at ₨ 275,000 (PKR). Solar pricing moves with supply, import duties and exchange rates, and distributors set their own margins, so treat this as a comparison reference and confirm the current figure before you order.
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 Phoenix locally before ordering.

How much does Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series cost?
Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series is listed at ₨ 275,000 (PKR). The figure is indicative — solar prices move with supply, duties and exchange rates, and each distributor sets its own margin — so confirm the current price with a supplier before ordering.
What are the specifications of Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series?
We hold 9 published specifications for this battery, including life cycle 5,000 cycles, nominal voltage 51.2 V, battery capacity 105 Ah, battery chemistry Lithium Iron Phosphate (LiFePO4) and cell configuration 16S (16 Cells in Series). The full table is on this page, listed under model PHEX-101.
Who makes Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series?
Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series is a Phoenix product, listed under batteries with model reference PHEX-101. The Phoenix brand page lists the rest of its range so you can compare across the catalogue.
Is Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series 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 Phoenix (RLW-5.4-X1) 5.37kWh Lithium Battery 51.2V 105AH Wall Series?
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.
