If you are like me, you have probably wondered : “how does a solar generator work ?”.  This post and this info graphic will give you a good overview of what goes into a solar generator. If getting into the weeds about the innards of a solar generator does not really interest you, you might like to read about the different types of solar generators available in the market. Solar Panel kits might also be a solution for your needs. But for those of you interested in the answer to our original question; how does a solar generator work?, we have to ask a  few more questions.

How does a solar generator work : what is a solar generator?

A solar generator is a compact electronic box which has three components integrated together. There is the charge controller, batteries and an inverter. Strangely thought there is no solar component in the solar generator. The solar panels need to be purchased separately. In reality, the solar generator is just a battery powered generator. As long as the battery inside the solar generator stays charged, it will be able to power a slew of devices as a backup generator.  You can charge the battery in the generator using external solar panels, or using a wall outlet ( regular 110 V) or even a char charger. Of course, not all solar generators are created equal and some of them might only allow one or two modes of charging.

The Solar generator is able to provide output power to a wide variety of devices. It can power smart phones, laptops, lights, a small refrigerator, a ham radio etc. They usually provide outlets for 110V devices like your laptop or usb ports for your phones or car charger outlets for devices which runs off them.  This is an excellent calculator which lets you size your solar generator or estimate what you can possible use with your solar generator. And onwards to the next big question.

How does a solar generator work : what is inside a solar generator?

Lithium Ion Battery

The three components within a solar generator are the charge controller, batteries and the inverter.  They are not necessarily separate, they are usually well integrated. Some of the more convenient solar generators allow you to swap the batteries. This is really good for longevity as over time batteries tend to degrade and poof there goes your solar generator to the junk yard.

Charge Controller

The charge controller is a critical component of the solar generator. It protects and ensures the longevity of the in built battery inside the solar generator. Depending on the type of battery, AGM, Gel or Lithium ion, they will have different characteristics for charging and discharging. The charge controller ensures this is automatically taken care off.

Inverter

The inverter actually converts the output of the battery into AC power that can be used to power any AC device. Of course Solar generators are not built to power large AC appliances like AC’s, but they do just fine for electronics, TV’s and low powered household devices. To understand what can actually be powered using a solar generator, you will need to read this article on different types of solar generators.

Solar Generator

The three components when integrated together result in a well designed solar generator like the YETI 150 shown above. You can ready more about this generator here as well. And of course to round up this master class on the solar generator, you have the solar panels. Solar panels are mostly sold separately, though there are some rather innovative but smaller solar generators which have built in solar panels like the Renogy Firefly Solar Generator.
