Review of the FoxESS EP11 10.36 kWh Battery Prices in Pakistan

As Pakistan moves toward a cleaner and more reliable energy future, solar storage is quickly becoming a household priority. Frequent load-shedding, rising electricity costs, and the desire for energy independence have made solar batteries more than a luxury they’re a necessity. Among the new-age storage options, the FoxESS EP11 10.36 kWh battery has caught the attention of many homeowners and installers. But how well does it actually perform? Let’s take a deep look at its features, real-world benefits, and market price in Pakistan.

What Is the FoxESS EP11?

The FoxESS EP11 is a high-voltage lithium iron phosphate (LiFePO₄) battery designed for residential and small commercial solar systems. With a nominal capacity of 10.36 kWh, it’s ideal for powering homes through the night or during grid outages. The EP11 can be scaled up by connecting multiple units  up to four modules  for a combined capacity of over 40 kWh.

It features a 90% depth of discharge and round-trip efficiency above 95%, meaning users can draw more usable power without wasting much energy in the charging and discharging process. Built to last over 4,000 cycles, the EP11 also comes with a 10-year warranty, which makes it one of the more reliable and long-lasting energy storage units in its class.

The battery uses passive cooling and carries an IP65 protection rating, making it resistant to dust and light rain  suitable for both indoor and semi-outdoor installation.

Strengths and Highlights

1. Modularity and Expansion

The modular design of the EP11 is one of its biggest advantages. You can start with a single unit and expand later if your energy needs grow. This flexibility makes it attractive for households who plan to increase solar capacity gradually.

2. High Efficiency and Deep Discharge

Thanks to its ≥95% round-trip efficiency, the battery loses very little energy during operation. Combine that with its 90% usable capacity, and homeowners get excellent energy utilization  perfect for running essential appliances during power cuts.

3. Compact and Flexible Design

The EP11’s slim, wall-mountable design (only about 147 mm deep) makes it ideal for tight spaces. Whether you install it in a garage, utility area, or shaded outdoor wall, it blends easily with most setups.

4. Silent and Low-Maintenance Operation

Unlike older battery systems with fans or moving parts, the EP11 operates silently. It doesn’t need constant servicing, making it a low-maintenance solution for everyday use.

5. Competitive Price Point

Compared with premium global brands like Tesla Powerwall or BYD, the FoxESS EP11 comes at a more accessible price without compromising quality. Its affordability gives it a strong foothold in emerging solar markets such as Pakistan.

6. Reliable Warranty Coverage

The 10-year performance warranty ensures peace of mind for long-term users. FoxESS guarantees a minimum 70% usable capacity even after years of use  a solid assurance for investment-conscious buyers.

Limitations and Considerations

1. Limited Brand History

FoxESS is relatively new in the global energy storage space compared to long-established brands. While early feedback is promising, it lacks extensive field data or large-scale user reviews in Pakistan so far.

2. Expansion Req

Though modular, adding new battery units requires proper voltage and state-of-charge matching. If not handled correctly, system balance issues may occur, so expansion should always be done by certified installers.

3. Software and App Maturity

Earlier versions of the FoxESS monitoring app were reported to have limited features or occasional connectivity issues. However, the latest updates are more stable, offering detailed real-time monitoring and energy analytics.

4. Temperature Sensitivity

The EP11 operates best between –10 °C and 55 °C. While this range covers most of Pakistan, extremely hot climates (such as interior Sindh) may affect long-term performance unless the unit is installed in a shaded, ventilated location.

5. Warranty Conditions

As with most batteries, warranty terms depend on proper installation and usage conditions. Over-discharge, improper expansion, or lack of periodic maintenance can affect warranty claims — so professional installation is essential.

Real-World Experience

In regions where FoxESS has been deployed  including Europe and Australia the EP11 has received positive reviews for its quiet operation, efficient performance, and easy scalability.

Users highlight the system’s simplicity and stable output even under fluctuating grid conditions. Some minor complaints relate to the monitoring app or communication delays, but the overall hardware reliability stands out. For Pakistani homes facing regular load-shedding, this stability and usable energy capacity could make a big difference in comfort and convenience.

Technical Specifications (Quick Summary)

Price in Pakistan

As of late 2025, the FoxESS EP11 10.36 kWh battery is available in Pakistan through authorized solar distributors and energy retailers. Prices vary slightly by city and supplier, but most listings fall within the range of ₨ 580,000 to ₨ 630,000 per module.

The total cost depends on system size, installation charges, inverter compatibility, and accessories such as cables, fuses, and brackets. A full home backup system (including inverter and installation) can range anywhere from ₨ 1.3 million to ₨ 1.8 million, depending on setup complexity.

Despite being a premium investment, its long life, zero maintenance, and high efficiency make it more cost-effective over time compared to diesel generators or frequent battery replacements.

Why It Makes Sense for Pakistan

With the country’s growing focus on renewable energy and the challenges of grid instability, storage systems like the EP11 offer real relief. It allows homeowners to store excess daytime solar energy and use it during nighttime or load-shedding hours, drastically reducing dependency on the grid.

For areas facing daily power cuts, the EP11 can easily power essentials like lights, fans, Wi-Fi routers, refrigerators, and even air conditioners for a few hours, depending on usage. Its scalability also makes it an excellent option for commercial setups or large households seeking reliable backup solutions.

Should You Buy It?

The FoxESS EP11 10.36 kWh battery is a smart, future-ready investment for homeowners who want clean, consistent, and expandable energy storage.

You should strongly consider it if:

• You already have or plan to install a FoxESS or compatible hybrid inverter.

• You need a quiet and efficient backup system.

• You value scalability and may expand your energy system later.

• You want reliable backup power during load-shedding.

• You prefer long-term energy independence over short-term savings.

However, ensure installation is done by an authorized technician familiar with FoxESS systems. This guarantees proper calibration, warranty validity, and safe operation.

Final Review

The FoxESS EP11 10.36 kWh is a solid contender in Pakistan’s growing solar battery market. It combines high efficiency, a large usable capacity, and modular scalability at a price that’s reasonable for its class. The design is elegant, the operation is silent, and the performance is dependable.

While FoxESS is still building its long-term reputation, early results are encouraging. For homeowners seeking freedom from load-shedding, lower electricity bills, and a modern solar-ready lifestyle, the EP11 delivers exceptional value.
