  • Mobile Equipment

Warranty Protection

Even though most solar manufacturers offer a 25-year warranty, there is a reason that the 10-year warranty is worth highlighting. The main reason is because the warranty is a true 10-year full repair/replacement warranty. Most solar clients will find that there is less help with a 25-year equipment warranty than the true 10-year protection offers. The warranty includes:

  • All battery packs covered
  • Automated warranty registration
  • Free repair and replacement
  • Full lifetime tech support and customer service

30-Day Money-Back Guarantee

It also generally takes substantial time for the repair or replacement parts to be delivered and installed. That is not the case with as the company will immediately ship out necessary parts. 


The Bad

  • No Solar Panels Sold
  • DIY Installation

No Solar Panels Sold

Despite offering solar accessories like inverters and chargers, there are no solar panels sold through This is not necessarily a concern for those with mobile power needs, but for those utilizing for residential needs, this can be concerning. A solar system will need to be installed previously in order for the battery pack to be connected.

Clients who utilize a solar company that only installs solar systems and does not offer battery/storage solutions can benefit from this. Otherwise, it makes more sense for a residential client to go through a solar provider that offers all equipment needs. 

DIY Installation

While does provide instructions for installation, professional installation is not available. Clients will have the equipment mailed directly to them and it is up to them to connect all system parts correctly in order for operation.

For mobile solutions, connecting the battery system for power is not as concerning, but it is a worry for residential customers. Most residential solar providers offer professional installation, but all equipment sold through requires DIY installation efforts.

Those looking to be more energy independent and searching for affordable solar battery solutions will likely find a number of options to choose from with Those more interested in the traditional solar system will have to go elsewhere for service.

Doug Roberts Mattoon, IL

I recently had a problem with my home solar system. when I contacted Big Battery a technician named Manny assisted me over the phone. He went above and beyond what I expected. he diagnosed the problem was with my inverter not the battery, he worked with me and managed to get my system back up and running. I am handicapped and suffer very high anxiety issues but he was able to work with both problems mine and the solar array. KUDOS to Big Battery for employing such capable people.

In short I purchased an inverter and a battery from BigBattery. Installed the two items. Had issues with the inverter from the start. 60+ emails and countless calls later I have an inverter that has almost completely stopped working and they now ignore me completely. Looking like I’m out $1200 on an inverter. Tech dept kept sending me the manual. Or talk to Growatt. Well they don’t seem to care either. Zero customer service. No one has made an effort to contact me to find a resolution. 🤷🏼‍♂️
