How do I add battery storage to my solar system?
Jun 11, 2025
As the global demand for renewable energy continues to grow, more and more homes and businesses are installing solar power systems. However, relying solely on solar panels to generate electricity is not enough to meet all-weather electricity needs. In order to achieve higher energy self-sufficiency and power stability, integrating a battery energy storage system into your solar system is a wise choice. As a professional manufacturer of battery energy storage products, GreenMore brings you a detailed guide to help you understand how to add battery storage to an existing or newly built solar system.
Why add battery storage to your solar system?
Improve energy self-sufficiency: When solar panels generate electricity during the day, excess electricity can be stored in batteries and used at night or on cloudy days.
Reduce electricity expenses: Through the "peak-valley arbitrage" strategy, the stored electricity is used during peak electricity price periods to reduce the purchase of electricity from the power grid.
Enhance power supply reliability: In the event of a power outage or grid failure, the battery energy storage system can serve as a backup power source to ensure the operation of critical loads.
Support green and sustainable development: improve the utilization rate of clean energy, reduce carbon emissions, and help achieve the carbon neutrality goal.
Choose the right battery type
GreenMore provides a variety of battery energy storage products to meet the needs of different customers. For home users, we recommend the following battery types:
Wall-mounted energy storage battery: This type of battery is easy to install, does not take up too much space, and is suitable for installation on the wall of the home. It has a high energy density and a long service life, making it an ideal choice for home energy storage.
Stacked energy storage battery: The stacked design allows the battery capacity to be flexibly expanded according to actual needs. If you plan to add electrical equipment or expand energy storage capacity in the future, stacked energy storage batteries will be a good choice.
Energy storage battery integrated machine: The integrated design integrates key components such as batteries and inverters, making installation more convenient and operation simpler. It is suitable for home users with low technical requirements and can quickly realize the energy storage function of the solar energy system.
Common solar energy + energy storage system configuration methods
GreenMore provides a variety of flexible battery energy storage solutions according to different application scenarios and user needs:
1.Grid-tied with Battery
Features: Connected to the public power grid, solar power generation is used preferentially during the day, and excess power can be stored in the battery or fed back to the grid.
Applicable scenarios: urban households, industrial and commercial users.
Recommended products: GreenMore wall-mounted energy storage battery (5kWh/10kWh), stacked energy storage battery (15kWh/20kWh).
2.Off-grid System
Features: Completely disconnected from the public grid, relying on solar power generation and battery storage to meet all electricity needs.
Applicable scenarios: remote areas, mountainous areas, islands and other areas without stable power grid coverage.
Recommended product: GreenMore energy storage device (supports customized capacity).
3.Hybrid Energy Storage System
Features: Combined with grid-connected and off-grid functions, the operation mode can be automatically switched according to the grid status.
Advantages: It takes into account both economy and high availability, and is suitable for users with higher power security requirements.
Recommended product: GreenMore modular energy storage system (supports expansion to more than 100kWh).
How to choose the energy storage battery that suits you?
When adding battery storage to your solar system, there are several key factors to consider:
1. Battery Type
The mainstream energy storage batteries on the market include lithium-ion batteries, lead-acid batteries and lithium iron phosphate batteries. GreenMore recommends using lithium iron phosphate batteries (LiFePOâ‚„):
High security
Long cycle life (up to 6000 times or more)
Support deep discharge
Environmentally friendly and pollution-free
2.Battery capacity
Home users: It is recommended to choose a battery with a capacity of 5kWh~20kWh, depending on the daily power consumption and load type.
Commercial and industrial users: They can choose customized large-capacity energy storage solutions based on the average daily electricity load and peak-valley electricity price policies.
♥ GreenMore provides standard products ranging from 5kWh to 20kWh, and supports customized systems with higher capacity on demand.
Detailed steps to add an energy storage system
Step 1: Evaluate your current solar system
Check the parameters such as PV panel power, inverter model, system voltage, etc.
Analyze daily electricity usage habits and load curves.
Step 2: Choose the right energy storage system
Choose the appropriate battery type and capacity based on power requirements, budget, and installation environment.
You can contact GreenMore technical team for personalized solution suggestions.
