Universal Energy Management


Order Learn Ask A Pro


Here at Humless, we wanted to create a smart ESS (Energy Storage System) that can handle it all. After two years of research and development, we're proud to introduce the Humless Universal battery-powered generator. The energy storage industry has been plagued with systems that work well for one application but doesn't work at all for another. We built an intelligent system of portable battery power for homes that can manage everything under the sun from retrofitting to existing solar arrays to storing power for large off-grid commercial businesses. No matter how complex your power needs are, the Humless Universal will work for you.

…In 2008, our family went camping in California’s redwood forests. Early one evening a nearby camper started up a diesel generator and let it run through the night. The peaceful forest was completely disrupted by the loud rumble and pollution of a traditional gasoline generator. We knew there had to be a better way to travel with power without the noise and environmental toxins. Our mission was (and still is) to create a clean, quiet, sustainable generator. We scoured the world to find a reliable and thoroughly tested solar generator and home battery technology to pair with solar panels for a long-lasting power solution.

In 2010, the original Humless lithium battery-powered generator for home was created. Since that day our product line has expanded to portable emergency power with the best battery-powered generator, but our core mission remains the same.


Our mission is to create the most reliable power storage systems. With the use of new and old technology, we are able to build home battery backup systems that store more power and last longer than ever before. Our state of the art lithium technology stores three times more than a traditional battery while able to be cycled up to five times more.

Easy Retrofit To Any Home With Portable Solar Emergency Power Kit

We’ve built a smart energy storage system that’s plug-and-play with any existing solar array. Our intelligent system recognizes what type of inverter the array is using and pairs with the system automatically. Retrofitting an existing array is as easy as running the AC and/or DC lines into a Humless portable solar generator system.

There are so many different battery-powered inverter generators and solar products on the market, creating a battery system that is efficient and reliable has traditionally required a skilled electrical engineer. Our new battery-powered ac generator takes the complexity out of energy storage.


Off-Grid and On-Grid Ready

Let’s face it, a battery system is useless if it doesn’t work when the grid fails. The Home Systems work on and/or off-grid. You can now load shift, export to the grid and have a battery-powered portable generator that works when the power goes out. Single application energy storage systems are a thing of the past. The Humless solutions do everything you might need out of an ESS (Energy Storage System).

Stackable Energy Storage

We’ve designed our Universal systems to easily expand by preconfiguring our hardware and software to pair with additional inverters and batteries. Now you can start with a small battery system and grow it over time. Start with a battery backup for essential loads then build it up to go completely off-grid and then add an electric car charging station.

Add additional inverters to manage more power input and output. We can now stack inverters to create 3 phase power. Whatever your power needs are, Humless has a solution.

Start your storage at 5 kWh’s and easily grow up to 70 kWh’s. Need more storage than that? No problem. After 70 kWh’s of battery storage, we will design a custom system to manage large residential all the way up to large commercial battery systems.
