Additional batteries are not included with any kits offered by Inergy. Also, note that the solar panel input is an EC8 connection. This is rare for solar generators to have this style input. This means that you will only be able to connect Inergy’s solar panels directly to the Flex.
However, Inergy has EC8 to MC4 adapters to allow you to use third-party solar panels with the Flex. They are not cheap, but they can be a great solution if you prefer having solar panels of a different brand charging the Flex.
Lastly, the Flex has a quick wall charger that is sold separately. This will crank up to 225W compared to the standard wall charger’s 100W. The quick wall charger will charge one battery in about five hours.
What Can the Inergy Flex Be Used for?
- Off-grid living or camping
- Backup for power outages
- Disaster relief
Most off-grid power needs can be served with the Flex. The only area where this system will have trouble is with extremely high power needs such as powering an entire home. This would require a higher AC continuous output to run appliances such as washers, dryers, and other demanding appliances of similar caliber simultaneously.
Inergy Flex – Pros
- Its inverter strength is still very powerful for a solar generator, with 1,500 watts of continuous power output from its AC ports.
- There are three different ways to keep the Flex fully charged. First is solar panel charging, which (at its max input) charges each battery in about three hours. Next is wall charging, and lastly from a car (using the car charger – sold separately). All these charging options can be used simultaneously, reducing the charge time to a minimum of about one hour.
- LCD screen that enables you to read the input/output wattage. The Flex’s screen also reveals the battery charge percentage as well as watts, volts, and amps you have left.
- It is budget-friendly and less expensive than other solar generators of its caliber.
Inergy Flex – Cons
- EC8 Input – The solar charging input is an EC8 connector, which means if you want to use third-party solar panels with the Flex, you’ll need to buy an EC8 to MC4 connector from Inergy.
You can find the Flex here on Inergy’s website. This is not an affiliated link.

POINT ZERO ENERGY TITAN
This is a very powerful solar generator with a 2,000-watt expandable lithium battery that serves different household power supply purposes.
The Point Zero Energy Titan is by far the biggest and most powerful solar generator on the market today.
Unlike other big solar generators, with two or more batteries, the Titan is capable of 3,000W continuous with 6,000W surge power. This is the best inverter rating for a solar generator by far. If you need a lot of power, the Titan will be your best option.
For example, the Yeti 6000X is Goal Zero’s largest solar generator, and that system’s inverter is rated at 2,000W continuous with 3,500W of surge power. This is still a big inverter, but the Titan dominates it.
Using only one of the Titan’s batteries with its power module still makes it more powerful than several of its competitors. You can power just about any household appliance and even some industrial equipment with this beast of a solar generator.
