Home Backup Power Solution: Gasoline Generator vs. Solar Energy Storage System


With frequent extreme weather events and power outages, having a backup power source at home has become increasingly important. Two common options for home backup power are traditional gasoline generators and more modern energy storage systems. In this article, we will analyze the advantages and disadvantages of these two backup power options to help you make the most appropriate choice.


What is Gasoline Generators

The gasoline generator operates on the principle of an internal combustion engine, initially mixing gasoline with air and igniting it inside the cylinder to generate an explosion that propels piston movement. The reciprocating motion of the piston drives the rotation of the crankshaft, which, in turn, converts mechanical energy into electrical energy output through the generator.

As a traditional backup power source, gasoline generators offer several advantages. They are relatively lightweight, portable, and suitable for outdoor and temporary power needs, providing flexibility. Additionally, gasoline, as a widely available fuel, offers users convenience. Moreover, gasoline generators are typically cheaper than energy storage systems, making them an important consideration for budget-conscious households.

However, gasoline generators have several limitations. Users need to purchase dedicated gasoline tanks for fuel storage at home. Operating costs fluctuate with gasoline prices. In some areas, gasoline supply may be restricted, making it difficult to obtain fuel during emergencies.

Incomplete combustion of gasoline emits carbon monoxide, making it unsuitable for use in enclosed indoor environments. Imagine having to venture outdoors on a stormy night during a power outage to manually start the generator, which can be quite unbearable. Operating gasoline generators also generate noise, which may impact the living environment.


What is Solar Energy Storage Systems

Using energy storage systems as household backup power is a more environmentally friendly choice and has gradually become mainstream in recent years.

Photovoltaic energy storage systems utilize solar panels to convert solar energy into direct current (DC) electricity, which is then converted into alternating current (AC) electricity through inverters. This electricity can be directly supplied to household electrical devices or stored in batteries for use during peak electricity pricing or power outages. By employing energy storage systems, solar photovoltaic systems can achieve higher self-sufficiency and energy utilization efficiency while improving the stability and reliability of the power system.

Complete systems typically include battery packs, inverters, and intelligent management apps, ensuring efficient energy conversion and management. Recently popular all-in-one solutions for solar energy storage, such as Hinen's Pro series, integrate inverters, switchboxes, and batteries into a single product, featuring a modern minimalist design and stackable structure for easy installation.

Household energy storage systems eliminate the need for gasoline storage and concerns about carbon emissions, minimizing environmental impact. When the grid fails, the system automatically switches to battery power to supply household loads, ensuring normal operation of daily life.

However, home energy storage systems also face challenges. Installing these systems typically requires high initial investment costs. Additionally, the energy storage capacity of these systems may be limited, especially during adverse weather conditions or periods of high energy demand. Safety performance is a significant consideration for energy storage batteries; choosing batteries without proper safety standards may lead to thermal runaway caused by internal chemical reactions.

Hinen's battery products, from BMS development to battery pack production, adhere to self-research and production. They feature five layers of battery protection: full coverage temperature detection; BMS intelligent control, over-temp, over- current, over-voltage protectionhort circuits; built-in physical short-circuit protection; internal fire extinguisher; decompression valves for safety and reliability.

Gasoline Generator vs. Solar Energy Storage System

Gasoline Generator

Energy Storage System


Compact, portable

Relatively large, fixed location

Initial Cost



Operating Cost

Depends on usage frequency and gasoline prices


Environmental Impact

Produces carbon monoxide emissions and noise

Relies on clean solar energy, environmentally friendly





No installation required

Requires professional installation

Convenience of Operation

Manual start-up

Automatic EPS switching


Change machine oil after initial 20 hours, then every 100 hours; replace filters every six months

Minimal maintenance; regular checks on wiring connections


The carbon monoxide gas produced by incomplete combustion indoors can cause poisoning

Using batteries lacking safety standards may lead to thermal runaway occurrences.



If you prioritize cost-effectiveness and portability, a gasoline generator may be the preferred choice. However, if environmental sustainability and long-term energy stability are important considerations, an energy storage system may better suit your needs. Ultimately, the decision depends on your specific circumstances and preferences. By carefully weighing the pros and cons of each option, you can find the most suitable backup power solution for your home.
