Reviews Fortress Power eVault 18.5kWh Lithium Battery - Today, we're going to talk about the fortress eVault. So the eVault is an 18.5 kilowatt-hour lithium iron phosphate battery. You can stack up to 12 of these batteries in a configuration somewhere in the order of 200 kilowatt-hours of total storage.

They have their own touchscreen display that provides you with the state of charge the battery voltage, your current flow in and out of the battery bank. Each battery has a 250 amp breaker at the top. So, from the terminals on the battery, its overcurrent protection 250 amps out to the loads. You could directly hook these up to an inverter, or you could wire them to a high current bus, and parallel multiple batteries together to gain a suitable capacity for your application.
This battery is great for larger-scale off-grid applications typically, the minimum obviously is going to be 18 kilowatt-hours. But, if you want to have building blocks of 18 kilowatt-hour chunks, that's where this particular battery is going to be best suited.

So, you know typically we'll be using these batteries for applications that are 30 kilowatt hours or more, because of the significant building blocks as a result of the 18 kilowatt-hour capacity of each of these individual banks.
Another cool feature of this battery is, that it's on casters. So, it weighs about 400 pounds but moving it around to where its final resting place is going to be is pretty easy with the casters. This particular battery has knockouts on the sides. On either side, it allows you to put in like a one-inch conduit, or one-inch string relief right into the battery.

And then the battery has a cover that you can screw on the top, and that allows the entire connections, and everything to be protected. So, you can run the conduit in a run, conduit up to your inverter, and then screw in the cover. And now, it's completely sealed up.
Okay, so this covers the fortress eVault battery. It's a very simple battery to integrate, it's pretty much, just a connect-up solution turn it on, set up your settings, it does offer some closed-loop communications with inverter systems.
