Get a Closer Look at Solar Inverter with Batteries: Pros and Buying Guide

IEETek off-grid solar Inverter

A solar inverter with batteries is an energy storage system that converts the DC generated by solar panels into AC while also storing excess electricity in the battery for future use. In the case of unstable electricity, it can serve as a backup source to ensure the normal operation of electrical appliances. This provides a stable backup electricity supply and can significantly decrease electricity costs. A solar inverter with batteries significantly reduces reliance on the grid. Moreover, long-term use of this clean energy also helps reduce carbon footprint, making it a strategic long-term investment.

Why Use a Solar Inverter with Batteries?

Many key advantages highlight the importance of installing a solar inverter with batteries. These include:

1. Stable Power Supply

Batteries store excess electricity during the day. You can then use this stored energy after sunset or when solar panels cannot generate power. This provides a reliable backup power source independent of grid outages. For example, you will realize its importance while cooking during a power outage.

2. Improve Energy Utilization Efficiency

By maximizing self-consumption of locally produced solar power, the solar inverter with battery system improves energy efficiency compared to feeding all surplus energy back to the grid or wasting it because every generated electricity is effectively utilized.

3. Save Electricity Costs

In off-grid scenarios or areas with high electricity prices, solar energy stored in batteries can significantly reduce monthly power bills by displacing grid consumption. In addition, self-sufficiency in electricity can also avoid power outage losses caused by grid failures. So, you will no longer be troubled by fluctuating electricity prices. 

4. Intelligent Power Management

Advanced inverters enable remote monitoring and control of power flows. Users can view power generation, battery charging status, and household or business electricity consumption in real-time, adjust output levels, and receive notifications to manage battery usage very efficiently. When the electricity level or price drops, it can also promptly remind homeowners, further enhancing the system’s stability.

Issues to Pay Attention to When Purchasing and Using the Solar Inverter with Batteries

The various types and capacities of products on the market have brought selection difficulties to users who are not familiar with them, but the following section can roughly help you screen which product is more suitable for you. Here are crucial factors to consider when purchasing a solar storage system kit with batteries and inverter:

1. What Size Solar Inverter with Batteries Is Needed?

Proper sizing requires considering application loads, solar panel efficiency, battery type, and desired backup times. An undersized solar inverter with batteries may not be able to process all the electricity from the solar panel, and oversized ones may mean unnecessary costs and resource waste.

In addition, due to the long service life of solar storage inverters, it is necessary to consider future electricity demand, including all connected appliances and equipment, and choose scalable ones to adapt to possible future load increases.

2. Efficiency and Safety Functions

An efficient solar inverter with batteries can generate more electricity under the same lighting time and conditions. Look for units with MPPT tracking and pure sine wave output, which are more efficient products than others. Furthermore, robust safety certifications and safety protection functions such as over-current and overload can protect components from damage.

3. How to Avoid Inverter Overload?

Carefully select an inverter power and capacity that align with your specific load requirement. You can check the rated power of household appliances and add them up to make the decision. Monitor its operating status and usage using the intelligent management function to prevent overloading, which can impact performance and lifespan.
