Frequently-Asked Questions
How long can I expect this battery to last with daily use? With a rating of 4,000 full cycles, expect years—often over a decade—of daily use before capacity falls below 80%.
Is it safe to install indoors? Yes. Being sealed and maintenance-free, it's safe for indoor use in cabins, boats, RVs, and workshops.
Can I combine two of these for higher voltage systems? Yes. These can be paralleled or arranged appropriately for higher voltage and capacity—just ensure your BMS and system setup supports it.
Does it support app-based monitoring? This LITE version focuses on performance and reliability—Bluetooth monitoring might not be included. Check if the full version (ALPHA 3) is needed for Bluetooth functionality.

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

Easy Return
I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!
