How to read this datasheet

FOX ESS EP12 11.52kWh Lithium Ion Solar Battery is listed with 7 published specifications from FOX, including efficiency of ≥ 95% Round-trip efficiency, nominal voltage of 384 V (Operating range: 348–438 V), charge of 30 A and cycle life of > 6,000 cycles. 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.

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.

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

FOX ESS EP12 11.52kWh Lithium Ion Solar Battery is listed at ₨ 695,000 (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 FOX locally before ordering.

FOX ESS EP12 11.52kWh Lithium Ion Solar Battery — frequently asked questions

How much does FOX ESS EP12 11.52kWh Lithium Ion Solar Battery cost?

FOX ESS EP12 11.52kWh Lithium Ion Solar Battery is listed at ₨ 695,000 (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 FOX ESS EP12 11.52kWh Lithium Ion Solar Battery?

We hold 7 published specifications for this battery, including efficiency ≥ 95% Round-trip efficiency, nominal voltage 384 V (Operating range: 348–438 V), charge 30 A, cycle life > 6,000 cycles and nominal capacity 11.52 kWh (10.37 kWh usable @ 90% DoD). The full table is on this page, listed under model WFOX-1.

Who makes FOX ESS EP12 11.52kWh Lithium Ion Solar Battery?

FOX ESS EP12 11.52kWh Lithium Ion Solar Battery is a FOX product, listed under batteries with model reference WFOX-1. The FOX brand page lists the rest of its range so you can compare across the catalogue.

Is FOX ESS EP12 11.52kWh Lithium Ion Solar Battery right for my system?

That depends on what it has to connect to. For a battery, check 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% 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 FOX ESS EP12 11.52kWh Lithium Ion Solar Battery?

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.
