Home Solar Energy Storage System Capacity Selection Guide: Helping You Find the Best Solution

Smart, Cost-Effective, Efficient Energy Storage Solutions Tailored to Your Needs

With global energy shortages and rising electricity costs, saving energy in the home has become a universal concern. Solar energy storage systems not only help households become energy independent, but they also provide emergency power during power outages or extreme weather conditions. Choosing the right capacity for a solar energy storage system is crucial to ensuring a stable power supply for your home. In this article, we will explain how to choose the right energy storage system based on your home’s actual needs and introduce Sottlot Power’s Alpha3000 solar hybrid inverter and DPE-5K battery system, making your home energy management more efficient and intelligent.

I. Why Do I Need to Choose the Right Energy Storage System Capacity?

1. Enhance Energy Independence With the increasing instability of the global power grid, particularly in remote or extreme climate areas, relying on solar energy storage systems guarantees uninterrupted daily life.
2. Save on Energy Costs By storing electricity generated by solar panels, you can reduce reliance on utility power during peak grid periods, leading to significant savings on your electricity bill.
3. Responding to Emergencies During natural disasters or power outages, the solar energy storage system can provide stable power to key equipment in your home, ensuring that daily life continues as usual.

II. Home Electricity Demand Assessment

1. Define Your Daily Electricity Demand The core of the home energy storage system is its capacity, and choosing the right solution depends on your home’s actual electricity consumption.
   • Basic Home Appliances (e.g., refrigerators, washing machines, lighting): These have more stable electricity consumption and require continuous power supply.
   • High-Power Appliances (e.g., electric stoves, air conditioners): These have high power demand for short periods.
   • Nighttime Electricity Consumption: Solar panels generate electricity during the day for charging, while the energy storage system provides power during the night.
2. Analyze Daily Power-Using Appliances
   

   Type of Appliance	Power (W)	Average Use Time (hrs/day)	Daily Electricity Use (kWh)
   Refrigerator	150	24	3.6
   Air Conditioner	1000	4	4.0
   Washing Machine	500	2	1.0
   Electric Stove	2000	1	2.0
   Lighting	50	6	0.3
   Computers and Other Light Equipment	100	8	0.8

   Formula:
   Total daily electricity consumption (kWh) = Power of each appliance (W) × Usage time (hrs) ÷ 1000

   Using this table, you can estimate your household’s total daily electricity consumption.

3. Distribution of Electricity Consumption Time
   • Daytime: Solar photovoltaic power is the primary source, and the energy storage system only supplements power on rainy days or during peak hours.
   • Nighttime: The energy storage system mainly supplies power, especially for appliances like refrigerators and lighting.

III. How to Choose the Capacity of the Energy Storage System?

Choosing the right capacity for the energy storage system is crucial based on your household’s electricity demand.

1. 5-10kWh: Suitable for Small and Medium-Sized Households
   Recommended Product: Sottlot DPE-5K (5.12kWh)
   Features: Supports power supply for daily low-power devices (e.g., lighting, computers). Ideal for nighttime use or as a basic emergency power supply.
   Application Scenario: Small families with fewer appliances and lower electricity demand.
2. 10-20kWh: Suitable for Medium-Sized Households
   Recommended Products: Expandable to 10-20kWh by paralleling 2-4 DPE-5K systems.
   Characteristics: Meets the continuous power needs of high-power appliances like refrigerators, air conditioners, and kitchen equipment.
   Application Scenario: Households with more electrical appliances and higher energy demands.
3. 20kWh or More: Large Households or Small Commercial Applications
   Recommended Product: The DPE-5K system supports up to 16 units in parallel, with a total capacity of up to 81.92kWh.
   Characteristics: Provides long-duration, high-power storage to meet very high electricity demands.
   Application Scenario: Large families or small commercial properties, such as villas and B&Bs.
