Description
Comparison: Ket-B vs. Ket-C
The primary difference between the two series lies in the module density:
-
Ket-B Series: Generally uses 205Ah modules. The range scales from 63kWh (60B) up to 136.4kWh (130B).
-
Ket-C Series: Uses higher-capacity 314Ah modules. The range scales from 96.5kWh (96C) up to 209kWh (209C).
Core System Architecture
The series is characterized by its high-voltage design, which significantly reduces energy conversion losses and allows for smaller cable cross-sections compared to traditional low-voltage (48V) systems.
-
Modular Design: The system is composed of individual SR-HOF10B battery modules connected in series.
-
Centralized Control: Every cluster is managed by the SR-PDU200B (Power Distribution Unit), which acts as the “brain,” monitoring safety, cell balancing, and communication.
-
Scalability: Capacity is increased by simply adding more modules to the stack (from 6 modules up to 13 modules).
Key Features & Technology
-
Industrial Safety Standards: The system features Triple Protection hardware, including Positive and Negative High-Voltage Relays and a physical 300A DC Breaker to ensure immediate isolation during faults.
-
Long Cycle Life: Designed for longevity, the cells are rated for 6,000 cycles (@25C, 0.5C), translating to approximately 15–20 years of service life under normal conditions.
-
Smart Monitoring: Integrated WiFi and Bluetooth support allow for remote management via the Tuya Cloud platform. Facility managers can monitor State of Charge (SoC), temperature, and health parameters in real-time.
-
High Efficiency: By operating at nominal voltages between 307V and 665V, the series matches perfectly with modern industrial three-phase hybrid inverters, ensuring conversion efficiencies often exceeding 97%.
Best Use Cases
The Ket-B series is the “workhorse” for businesses in regions with unstable grids (like Cameroon). It is ideal for:
-
Hospitality: Keeping hotels and resorts fully operational, including AC and elevators.
-
Agriculture: Powering irrigation pumps and climate-controlled poultry or livestock facilities.
-
Retail: Supporting large supermarkets and cold-chain storage to prevent stock spoilage.
-
Manufacturing: Providing a stable energy buffer for production lines and light machinery.

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.
