What these specifications mean
Fox EP5 5.18kW IP65 Lithium Ion Battery is listed with 10 published specifications from FOX, including temperature range of -20°C to 60°C, nominal voltage of 51.2V, battery chemistry of Lithium Iron Phosphate (LiFePO₄) and capacity of 5.28kWh. 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 communication protocol (CAN or RS485) for talking to the inverter, 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. 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.
Choosing a battery: the checks that matter
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.
- 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.
- 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.
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 in Pakistan
No price is published for Fox EP5 5.18kW IP65 Lithium Ion 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 FOX locally before ordering.
Fox EP5 5.18kW IP65 Lithium Ion Battery — frequently asked questions
What are the specifications of Fox EP5 5.18kW IP65 Lithium Ion Battery?
We hold 10 published specifications for this battery, including temperature range -20°C to 60°C, nominal voltage 51.2V, battery chemistry Lithium Iron Phosphate (LiFePO₄), capacity 5.28kWh and cycle life Approximately 6,000 cycles at 80% Depth of Discharge (DoD). The full table is on this page, listed under model WFOX-18.
Who makes Fox EP5 5.18kW IP65 Lithium Ion Battery?
Fox EP5 5.18kW IP65 Lithium Ion Battery is a FOX product, listed under batteries with model reference WFOX-18. The FOX brand page lists the rest of its range so you can compare across the catalogue.
Is Fox EP5 5.18kW IP65 Lithium Ion 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 Fox EP5 5.18kW IP65 Lithium Ion 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.
