Factors to Consider
When choosing an energy storage battery, you should consider your household or business power needs, installation space, budget, and local regulations.
All Seplos batteries use LiFePO4 (Lithium Iron Phosphate) cells—known for high safety, long lifespan, and eco-friendliness.
Let us get started with the compact 5kWh home battery.
5kWh: The Essential Starter
The 5kWh home battery belongs to the 104 series, using 3.2V 104Ah LiFePO₄ cells with a cycle life of up to 4,800 cycles—enabling over 10 years of service with daily use.
It features Seplos BMS 3.0 for intelligent monitoring and protection, including:
- Built-in aerosol fire extinguisher for enhanced safety
- External short-circuit protection switch
- Passive balancing to maintain cell consistency
- Bluetooth connection for mobile app monitoring (real-time power, temperature, and health data)
Suitable Household Size and Power Example
Perfect for small homes or apartments (1–2 people) with daily power usage between 5–10kWh.
In the event of a power outage, it can support essential appliances such as:
| Appliance | Power (W) | Note |
| Refrigerator | 100–200 | Intermittent operation, ~100W average |
| LED Lighting | 50 | Total |
| Laptop | 50 | — |
| Fan | 50 | — |
| Router | 10 | — |
Total load: ~260W
Considering inverter efficiency (90%), usable energy ≈ 4.5kWh.
Backup time: 4.5 ÷ 0.26 = ~17 hours.
If only powering the fridge (~100W), it can last up to 45 hours.
Available Installation Types
- Wall-mounted – space-saving, clean look, ideal for apartments.
- Rack-mounted – modular and easy to integrate with inverter cabinets.
- Stackable – expandable and mobile, allowing future capacity upgrades.
10kWh: The Family All-Rounder
The 104-L model is a wall-mounted 10kWh unit using 3.2V 104Ah LiFePO₄ cells (4800 cycles).
It includes Seplos BMS 3.0, built-in aerosol fire suppression, and short-circuit protection.
With an IP65 waterproof and dustproof rating, the 10kWh home battery can be installed outdoors—important in regions like Australia, where outdoor installation is required by law.
Suitable Household and Power Example
Ideal for medium-sized families (3–4 people) with daily usage of 10–15kWh.
| Appliance | Power (W) |
| Refrigerator | 150 |
| Lighting | 100 |
| TV | 100 |
| Computer | 100 |
| Microwave (intermittent) | 1000 |
| Water Pump | 500 |
Average load: 500W
Usable energy: 10 × 90% = 9kWh
Backup time: 9 ÷ 0.5 = 18 hours (or up to 45 hours for basic use).
16kWh: The Powerhouse
This battery uses 3.2V 314Ah LiFePO₄ cells with 6,000 cycles, providing a lifespan of over 15 years.
It includes Seplos BMS 3.0, aerosol fire suppression, and comes in two versions:
- Stackable type: fixed installation (movable with optional base)
- Vertical type: movable and flexible for repositioning
Suitable Usage
Best for large households or small businesses (4–5 people) with 15–20kWh daily usage.
Can power high-load devices such as air conditioners or EV chargers.
Example load:
| Appliance | Power (W) |
| Air Conditioner | 1500 |
| Refrigerator | 200 |
| Lighting | 150 |
| Water Heater | 1000 |
| EV Charger | 2000 |
Average load: 1000W
Usable energy: 16 × 90% = 14.4kWh
Backup time: 14.4 ÷ 1 = 14.4 hours, or up to 48 hours for basic loads.
Its long life and flexibility make it ideal for areas with frequent outages or extreme weather.
32kWh: The Ultimate Solution
The 32kWh model also uses 3.2V 314Ah LiFePO₄ cells (6000 cycles) and includes several key upgrades:
- Seplos BMS 3.0 + 15A active balancing board for improved cell performance
- Aerosol fire extinguisher + short-circuit protection
- Fan cooling system for better heat management
- Caster wheels for easy movement
Suitable Household Size
With its large capacity, the 32kWh battery is ideal for large houses, villas, or multi-generational families, typically with five or more members and daily power usage ranging from 25–40kWh.
It’s also perfect for households equipped with large solar PV systems aiming for maximum self-sufficiency, or for users living in regions prone to long power outages.
What It Can Power
During a blackout, a 32kWh Seplos system can support nearly the entire home’s essential loads, including:
- Central air conditioning or large split-type AC units (cooling/heating)
- Refrigerator and freezer
- Whole-house lighting (LED)
- TV, computer, router, and entertainment/network devices
- Water pump (for well or pressure boosting systems)
- Electric water heater (intermittent use)
- Kitchen appliances such as a microwave, a kettle, or an induction cooker (should be used alternately to avoid high peak loads)
Example Scenario: Summer Power Outage Simulation
Imagine a five-person villa experiencing a power outage on a summer night.
They wish to maintain comfort and basic living conditions.
Here’s their approximate power consumption:
| Appliance | Running Power | Note |
| Central Air Conditioner (Ground Floor) | 3000W (3kW) | Keeps the main area cool |
| Refrigerator | 150W | Average continuous power |
| LED Lighting (whole house) | 200W | — |
| TV & Audio System | 200W | — |
| Router + NAS | 30W | — |
| Basement Drain Pump | 400W | Average continuous power |
| Total Continuous Load | ≈3980W (≈4kW) | — |
Step 1 – Usable Energy:
Considering inverter efficiency (90%) and depth of discharge,
Usable energy = 32kWh × 90% = 28.8kWh
Step 2 – Backup Duration:
Runtime = 28.8kWh ÷ 4kW = 7.2 hours
Result:
In this scenario, the 32kWh system can power the above appliances for about 7 hours,
meaning it can easily sustain the household from night until early morning, ensuring comfort and peace of mind during most outages.
Alternative Scenario: Basic Load Mode
If the family prefers to extend backup time, they can switch off high-power devices like the air conditioner and keep only the essentials running:
Basic load calculation:
Refrigerator (150W) + Lighting (200W) + TV & Internet (230W) + Water Pump (400W) = ≈980W (≈1kW)
Backup duration:
28.8kWh ÷ 1kW = 28.8 hours
This means the system can continuously power basic household appliances for more than a full day (nearly 29 hours), showcasing its remarkable endurance and reliability for long outages.
