Description
The SRNE SR-EOS15B is the “Ultra-Capacity” flagship of the EOS residential series. While the SE series focuses on a slim, wall-mounted profile, the EOS series is designed for high-performance versatility and ruggedness, featuring a robust, floor-standing tower design that can also be wall-mounted. It utilizes the latest high-density 314Ah battery cells, pushing its total capacity to a massive 16.07kWh—making it one of the largest single-unit 48V residential batteries available.
Core Product Features
-
Massive Single-Unit Power: At 16.07kWh, the EOS15B is a true “grid-replacement” battery. A single unit provides enough energy to sustain an entire household for a long duration, reducing the need for complex parallel wiring of multiple smaller modules.
-
Superior Lifespan (8,000 Cycles): Utilizing premium grade 314Ah cells, this model boasts a cycle life of 8,000 cycles. In a typical Cameroon home with daily load-shedding, this translates to over 20 years of reliable service.
-
IP65 All-Weather Protection: Unlike many residential batteries (IP20/IP30), the EOS15B is IP65 rated. This means it is highly resistant to dust and moisture, making it much more durable in humid coastal environments like Douala or dusty regions in the North.
-
Intelligent Monitoring Suite: It features a large built-in LCD touchscreen for real-time local monitoring. It also includes integrated WiFi and Bluetooth for remote management via the Tuya Cloud, giving you deep insights into State of Health (SoH) and State of Charge (SoC).
-
High Discharge Current (200A): The robust BMS supports a continuous 200A discharge. This allows you to run high-wattage appliances like electric water heaters, boreholes, and multiple AC units simultaneously without fear of the battery shutting down.
-
Flexible Mobility & Installation: Despite its 123kg weight, it is designed with large universal wheels for easy positioning during installation. It supports both vertical floor-standing and horizontal wall-mounting.
-
Target Market: Premium luxury villas, small private hospitals, and critical business offices.
-
Real-World Power: A single EOS15B is the ultimate backup for a modern 4-bedroom home. It can comfortably run all lights, multiple fridges/freezers, and two 1.5HP Inverter AC units for an 8-hour power outage, ensuring your lifestyle remains completely uninterrupted.

Choosing between the SRNE SE Series and the SRNE EOS Series depends largely on your environment and installation space. While both are top-tier 48V (Low-Voltage) LiFePO4 systems, they cater to different residential priorities.
The SE Series is the “Aesthetic Wall-Mount” choice—ideal for indoor hallways and clean installations. The EOS Series is the “Rugged Flagship”—offering superior weather protection, a touchscreen interface, and a longer cycle life for harsh conditions.
Key Differences to Consider
1. Durability & Environment (IP65 vs IP30)
In Cameroon, the EOS Series has a distinct advantage in coastal cities like Douala or Kribi. Its IP65 rating means it is fully sealed against the heavy humidity and salt air that can corrode internal electronics. The SE Series (IP30) is better suited for a clean, air-conditioned battery room or a well-ventilated indoor space in Yaoundé or Bafoussam.
2. User Interface
The EOS Series feels more premium because of its integrated touchscreen. You can check your battery’s health, current usage, and cell voltages directly on the unit. The SE Series relies primarily on its LED strip for a quick glance, requiring you to open the Tuya App on your phone for detailed data.
3. Depth & Footprint
If you are installing a battery in a narrow corridor, the SE Series (specifically the 5kWh SE05B) is famously thin—only 15cm deep. The EOS Series has a more “blocky” tower design (approx. 20–27cm deep) and includes wheels for the larger models, making it easier to move but taking up more floor space if not wall-mounted.
Which one should you choose?
-
Choose the SE Series if: You want a clean, professional look on your wall, you are installing it strictly indoors, and you want a slightly more competitive price point for the 5kWh and 10kWh sizes.
-
Choose the EOS Series if: You live in a high-humidity area, you want the absolute longest possible lifespan (8,000 cycles), or you need the massive 16kWh single-unit capacity to run your entire house.

Tamsolec Warranty Assurance & Logistics Policy
At Tamsolec, we understand that a manufacturer's warranty is only as good as the support behind it. Because we operate as a bridge between international manufacturers and the local Cameroonian market, we offer an Optional Warranty Assurance Plan to give our clients total peace of mind.
1. The 5% Warranty Assurance Fee
We offer an optional Warranty Assurance Coverage at a flat rate of 5% of the total product cost.
By opting for this coverage, you are not just buying a product; you are securing a guarantee of service. This small investment ensures that Tamsolec takes full responsibility for the "logistics of replacement."
2. What This Policy Covers
When you pay the 5% Assurance Fee, Tamsolec commits to the following during the item's official warranty period:
-
Active Advocacy: We act as your legal and technical representative to the manufacturer (e.g., Felicity Solar) to ensure your warranty claim is prioritized and approved.
-
Logistics Management: We handle the complex process of returning a defective unit to the regional supplier (Douala/Yaoundé) or the manufacturer and securing the replacement.
-
Direct Replacement: Where possible and subject to availability, we aim to provide a replacement unit from our partner network to minimize your system's downtime.
-
Zero Hidden Fees: For covered claims, the 5% fee covers the administrative and local transport costs associated with the swap.
3. Why This Is Necessary
Standard manufacturer warranties often cover the parts, but they rarely cover the cost of logistics, transport, or the labor required to facilitate a swap between cities or countries.
Without this optional coverage, the buyer is responsible for transporting the damaged item to the authorized service center and following up on the weeks-long (or months-long) administrative process.
4. Terms & Exclusions
-
Original Condition: The warranty (and this assurance) only applies to items that have failed due to manufacturing defects under normal use.
-
Standard Exclusions: Damage caused by lightning (if no SPD was installed), physical impact, water submersion (for non-IP65 items), or unauthorized repair attempts by third-party technicians will void the warranty.
-
Non-Refundable: The 5% fee is a service charge for the duration of the warranty period and is non-refundable once the product has been commissioned.
Secure Your Investment
To add this coverage to your purchase, please inform us during the discussion phase. We highly recommend this for high-value items like Lithium Batteries and Hybrid Inverters.
