Description

This plan is arguably the best value for money in the lineup for households that do not need to power a refrigerator. For only 60,000 XAF more than the starting plan, you upgrade from old battery technology (Gel) to modern Lithium, and you get 50% more solar power.

1. Technical Specifications

🔋 Battery: 1.28kWh Lithium (LiFePO4)

This is the most critical upgrade over the 400,000 XAF plan.

  • Technology: Lithium Iron Phosphate (LiFePO4).

  • Capacity: 12.8V 100Ah = 1,280 Watt-hours.

  • Usable Capacity: ~1,200 Watt-hours.

    • The “Lithium Advantage”: While the 400k plan has a 100Ah Gel battery, you can only safely use 50% of it (~600Wh). This Lithium battery allows you to use nearly 95% of its capacity.

    • Result: You get Double the Backup Time of the 400k plan, even though the battery looks the same size physically.

  • Lifespan: 10+ Years (vs. 2-3 years for the Gel battery in the cheaper plan).

☀️ Solar Panels: 3x 200W Monocrystalline (or 2x 300W)

  • Total Solar Input: 600 Watts.

  • Performance: This is a 50% increase over the 400k plan.

  • Benefit: With 600W of input, you can charge the battery much faster. Even on cloudy days, this system will harvest more energy, ensuring your battery is full before nightfall.

⚡ Inverter: Cworth Energy 1.8KVA Hybrid

  • Continuous Power: 1500 Watts (1.5kW).

  • Type: Hybrid Inverter with built-in Solar Charge Controller.

  • Function: seamlessly switches between solar, battery, and grid (ENEO) power without your TV flickering.

2. What Can It Power?

This system is designed for Lighting, Entertainment, and Connectivity.

✅ Supported Appliances:

  • Entertainment: Smart TV (up to 65″), Decoder (Canal+), Home Theater/Soundbar.

  • Lighting: 10-15 LED Bulbs (You can light up a whole apartment).

  • Cooling: 2 Standing Fans.

  • Work: 2 Laptops, WiFi Router, Phone Chargers.

  • Small Appliances: Clippers, Blender (short use), Inkjet Printer.

❌ NOT Supported (Do Not Use):

  • Refrigerators / Freezers (The battery capacity is great, but the startup surge of a fridge might overwhelm the system or drain the battery too fast for a 24-hour cycle).

  • Electric Irons, Kettles, Microwaves.

  • Air Conditioners.

3. Expected Usage Time (Scenarios)

Unlike the 400k plan, this Lithium battery allows you to run your appliances deep into the night without worry.

Scenario A: “The Long Movie Night”

  • Appliances On: 55″ TV + Decoder + Sound System + 4 Lights + 1 Fan.

  • Total Load: ~180 Watts.

  • Estimated Runtime: 6 to 7 Hours.

    • Comparison: The 400k plan would die after ~3 hours with this load. This plan gets you through the entire evening (e.g., 6 PM to 1 AM).

Scenario B: “Work From Home” (Daytime)

  • Appliances On: Laptop + External Monitor + WiFi + Fan + Desk Light.

  • Total Load: ~120 Watts.

  • Estimated Runtime: Unlimited / Continuous.

    • With 600W of solar panels, you have plenty of surplus power. You can run your office and charge the battery from 0% to 100% in about 3 hours simultaneously.

Scenario C: “Basic Backup” (Lights & Phones)

  • Appliances On: 4 LED Lights + Phone Charging + WiFi.

  • Total Load: ~40 Watts.

  • Estimated Runtime: 24+ Hours.

4. Summary Comparison: Why pay the extra 60,000 XAF?

If you are debating between the 400k and 460k plans, here is the math:

Feature 400,000 XAF Plan 460,000 XAF Plan (Recommended)
Battery Tech Gel (Old Tech) Lithium (New Tech)
Real Usage ~600Wh (50% depth) ~1200Wh (95% depth)
Battery Life 2-3 Years 10+ Years
Solar Power 400 Watts 600 Watts (+50% Power)
Value Good Starter Excellent Long-Term Investment

Recommendation:

Unless you literally cannot find the extra 60,000 XAF, buy this 460,000 XAF plan instead of the 400,000 XAF plan. You get double the usable power and 5x the lifespan for a 15% price difference.

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.
