I'm really happy with this battery. Connected it to my EG4 Gridboss 18 hybrid inverter and 2 EG4 batteries in parallel with it. I made the Powermega battery the main one to communicate to the inverter to make sure it would get charged to 100% along with the 2 EG4 batteries as it was not always getting charged to 100% when the smaller capacity ED4 batteries where controlling the charging. Battery was delivered in perfect condition as it was very protected from damage during shipping. Great value for the money.

Much pricier than sealed lead acid for home battery bank, but lasts longer and stores more energy. We had purchased the inverter/battery combo, but added a second battery so our kids could run AC in their room all night. We've had them two months so far, and they work great!

I now own two. High quality and incredible price. These two batteries would have cost me 16k just five years ago. The only issue was the loooong shipping time from California on both, but well worth the wait.

I have been putting together my own solar battery storage systems for a while and adding this Eco-Worthy 48V unit was an easy decision. Having a massive 16.1kWh of energy storage in one block really simplifies the whole build. I usually make my own custom copper cables and crimp everything myself, and the connections and built-in breakers on this battery made the final installation super smooth and safe. It easily handles the heavy loads from my solar charge controllers and inverters without a single hiccup. If you are serious about building up your home power backup and getting your energy expenses down, this is a fantastic piece of hardware. Five stars.

Excellent communication. Battery arrived on time with no damage. The battery functions as advertised with Ah slightly higher than advertised. I will be buying more. I like the fact that it doesn’t take up a lot of space. Pretty easy to get set up and running.

Battery seams to be solid but the manual posted for the battery on this Amazon listing and on their web page claims WIFi connection but unit only comes with Bluetooth so you can only monitor it locally. After a FW update the WiFi is now working but be aware it might not work out of the box.
