Description

Here is the detailed breakdown for the 4KW Home Backup Package priced at 930,000 XAF.

This plan represents a significant jump in power capability compared to the 1.5KW series. While the battery size is similar to the middle-tier plan, the Inverter is more than twice as powerful. This changes the system from a “Lighting & Entertainment” backup to a true “Household Management” system that can handle heavy appliances like water heaters and blenders.

1. Technical Specifications

Inverter: Cworth Energy 4KVA/4KW Hybrid

  • Continuous Power: 4,000 Watts (4KW).

  • Surge Power:  8,000VA (for starting heavy motors).

  • Significance: Unlike the 1.5KW plans, this inverter will not trip if someone accidentally turns on a hair dryer, an electric iron, or a microwave. It has the muscle to run almost any standard household appliance.

  • System Voltage: 24V (paired with the 2.56kWh battery).

🔋 Battery: 2.56kWh Lithium (LiFePO4)

  • Capacity: 2,560 Watt-hours (2.56 kWh).

  • Technology: Lithium Iron Phosphate (Safe, 10+ year lifespan).

  • Crucial Note: While the Inverter is huge (4KW), the Battery is medium-sized. Think of this as a car with a massive V8 engine (the inverter) but a medium-sized gas tank (the battery). You can drive very fast (use high power), but if you do, the tank empties quickly.

☀️ Solar Panels: 3x 400W Monocrystalline

  • Total Output: 1,200 Watts.

  • Performance: Generates ~4,800Wh to 5,500Wh per day.

  • Recharge: Can refill the battery in about 2.5 hours of peak sun.

2. What Can It Power?

The 4000W limit opens the door to heating and motor appliances that cheaper plans strictly forbid.

✅ Supported Appliances (Heavy Loads):

  • Water Heater: Can run a standard electric water heater (1500W-2000W). Caution: Uses battery fast.

  • Kitchen High-Power: Blender, Microwave, Electric Kettle, Toaster.

  • Cleaning/Utility: Ironing (Electric Iron), Washing Machine (Cold wash recommended), Vacuum Cleaner.

  • Pumps: Can start water pumps (up to 1-1.5HP).

✅ Supported Appliances (Standard Loads):

  • Refrigeration: Large Fridge or Freezer (Run 24/7).

  • Entertainment: Multiple TVs, Sound Systems, Gaming Consoles.

  • Lighting: 12+ Bulbs (Whole house).

  • Cooling: Multiple Ceiling/Standing Fans.

❌ NOT Supported:

  • Large Air Conditioners: While the inverter can technically start a small AC (1HP), the battery is too small to run it for more than 1-2 hours. (For ACs, look at the 1.445M plan).

3. Expected Usage Time (Scenarios)

Scenario A: “The Morning Rush” (High Power Use)

  • Action: You boil water (Kettle), use the Microwave, and Iron clothes for 15 minutes.

  • Load: ~2,000 Watts (intermittent).

  • Result: The system handles this easily without tripping.

  • Battery Impact: This burst of activity might consume 15-20% of your battery in just 20 minutes.

Scenario B: “The Water Heater” (Cautionary Tale)

  • Action: You turn on the electric Water Heater for a shower.

  • Load: ~1,500 Watts constant.

  • Runtime: The battery would go from 100% to 0% in roughly 1.5 Hours.

  • Tip: Only run the water heater during the day when the sun is helping, or for short bursts (20 mins) at night.

Scenario C: “Standard Night” (Power Outage)

  • Appliances On: Fridge + TV + Lights + Fans (No heavy appliances).

  • Total Load: ~250 Watts.

  • Runtime: 8 – 10 Hours.

    • Note: Even though the inverter is huge, if you stick to low loads, the battery lasts just as long as the 750k plan.

4. Why Choose This Plan (930,000 XAF)?

You are paying the extra ~180,000 XAF (compared to the 750k plan) strictly for the Inverter Power.

  • Choose the 750k Plan IF: You just want lights, TV, and Fridge, and you promise never to plug in an iron or kettle.

  • Choose this 930k Plan IF: You want a “Real House” experience where you don’t have to panic if someone plugs in a Blender, Microwave, or Iron. It offers “Surge Protection” peace of mind, even if you can’t run those heavy items for hours on end.

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.
