What is a Solar Inverter Generator?

A solar inverter generator combines a large-capacity rechargeable power station (with a big battery at its heart) with solar panels. It can help provide backup power in emergencies or serve as a powerful portable power source for camping, tailgating and backyard DIY projects.

The generators are rated in output watt hours and have different types of ports. Some even allow you to monitor and manage the device via a mobile app.


A solar generator is a great backup power solution if you live in an area that is prone to weather-related electricity outages. It can also help you save money on your electric bills, especially when used during peak electricity hours. It is also a green alternative to traditional gas generators. However, it’s important to know that it will require an initial investment in solar panels and a solar generator.

A typical solar generator consists of a battery pack (usually lithium-ion NMC or LiFePO4/LFP chemistry) with an inverter that converts direct current energy into alternating current to run AC appliances and devices. It also has AC outlets, usually two or three on smaller units and up to six ports on medium and large models, plus a mix of USB-A 2.4V and 5V and USB-C with power delivery (PD) ports that support up to 100W.

The inverter and battery pack is protected by a built-in battery management system, or BMS. This ensures that the battery doesn’t overcharge or overdischarge, which is vital for maintaining a long life and high performance.

The amount of electricity that a solar generator can power depends on the capacity and watt-hours of its inverter, as well as the amount of sun it receives. It’s also important to note that solar generators can only provide a maximum amount of power per period, not continuously. This means that a device like an electric fan will not overtax a generator as much as a hairdryer or portable induction burner.


Solar generators absorb energy from sunlight and convert it to electricity that’s stored in a battery. They include a charge controller that regulates the volts and amps that go into the battery to ensure its safety. The inverter on a solar power station converts the direct current (DC) from the battery into alternating current (AC)—the type of power that most devices and appliances use.

Solar power stations come in a wide range of sizes, from large units that can keep your lights and appliances running during an outage to compact models solar inverter generator that are ideal for camping or tailgating. You can also customize your solar power station by adding an external battery pack for additional capacity.

The wattage of the batteries and panels on your solar generator determine how much power it can produce at any given time. For example, a 70W electric fan may not tax your generator but a 1,800W portable induction burner might overtax a medium-sized model. The wattage of your panel array is also important because the MPPT charge controller on most solar generators won’t let you hook up more panels than its maximum input wattage.

If you’re looking for a solar generator that can run heavy appliances like air-conditioners, check out the Goal Zero Yeti 1500X. This mid-sized model uses a lithium iron phosphate (LiFePO4/LFP) battery that’s expandable to 2,970 Wh and features a powerful 2,000W inverter.


Most consumers want their products to last long. While this is a common expectation, the lifespan of a solar power generator depends on several factors such as its quality and durability.

A solar generator combines a battery, voltage regulator, and power inverter into one compact system to transform solar energy into usable electrical current. It can be used to power a wide range of appliances, from small devices like phones and laptops to bigger ones, such as a refrigerator and television.

The most important component of a solar generator is the battery. The battery’s storage capacity determines how long the generator can run between charges. While lead acid batteries have a high storage capacity, they require long and frequent charging, which shortens their lifespan. NiMh (nickel manganese cobalt) and lithium-ion batteries are better options for their longer lifespans. They also tolerate higher temperatures and provide more efficient discharge rates.

Ideally, the generator’s battery size should match its energy requirements. This ensures efficient charging and prevents deep discharges, which shorten the battery’s lifespan. Additionally, the generator should have a Battery Management System (BMS) to monitor the state of charge and adjust its load. Moreover, the battery should be stored in a climate-controlled and dry place away from direct sunlight to avoid overheating. It should be charged at least once a month to maintain the battery’s performance and lifespan.

Silent Operation

At heart, a solar generator Solar Inverter Generator Manufacturer is a large rechargeable power station that pairs a battery (generally of lithium-ion) with an inverter to store and convert energy from the sun. They can keep essential appliances like lights and refrigerators running during emergencies or be used for off-the-grid camping, tailgating and other outdoor activities.

Solar panels comprise photovoltaic cells that convert sunlight into direct current (DC) electricity, while the inverter transforms the DC power from the batteries into alternating current (AC) energy that powers most devices. This makes solar generators quieter and more environmentally friendly than traditional gas generators, as they don’t emit any noise or toxic gases.

Many models also feature input options that allow for multiple solar panel attachments and battery additions, allowing them to be expanded to provide more power when needed. This flexibility can help you save money and invest in a system that meets your specific energy needs.

Most of these units use lithium-ion batteries, which are lightweight, highly efficient and have a long lifespan of thousands of charge-discharge cycles. They typically have a rated output of 500W for small units, 1,200W for medium-sized ones and 2,000W for larger solar generators. Unlike a conventional generator, inverters adjust their engine speed to match the power demand, which allows for higher fuel efficiency and lower noise levels.
