Fortress Evault 18.5Kwh – Fortress battery methods utilize the business’s most environmentally benign chemistry- Lithium Ferro Phosphate, which eliminates working temperature constraints, toxic coolants, and the chance of thermal runaway and fire. The built-in sensible Battery Management System (BMS) integrates multilevel security ideas: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Fortress Evault 18.5Kwh
Fortress high-performance Lithium Batteries are manufactured at the highest quality customary. It comes with a big power capability and fast charging and continuous discharge power. The proprietary architecture and BMS remove the necessity for cooling or air flow, which creates an efficient round-trip conversion.
The Fortress Lithium Battery is protected, straightforward to install, consistently dependable, and highly efficient. It provides you the lowest lifetime energy cost

They have their own touchscreen display that gives you with the state of charge the battery voltage, your current flow out and in of the battery bank. Each battery has a 250 amp breaker at the top. So, from the terminals on the battery, its overcurrent safety 250 amps out to the masses. You could directly hook these up to an inverter, or you would wire them to a excessive current bus, and parallel a number of batteries together to gain an appropriate capacity for your software.
This battery is great for larger-scale off-grid purposes sometimes, the minimal obviously goes to be 18 kilowatt-hours. But, if you wish to have building blocks of 18-kilowatt-hour chunks, that’s the place this specific battery is going to be greatest suited.
Fortress eVault 18.5kWh
So, you understand sometimes we’ll be utilizing these batteries for applications that are 30 kilowatt hours or extra, due to the significant constructing blocks because of the 18 kilowatt-hour capacity of every of those particular person banks.
Another cool function of this battery is, that it’s on casters. So, it weighs about 400 pounds however transferring it round to the place its final resting place goes to be is pretty easy with the casters. This explicit battery has knockouts on the sides. On both aspect, it allows you to put in like a one-inch conduit, or one-inch string aid right into the battery.

Fortress Power VS Tesla Powerwall
Comparison between the Fortress power battery and the Tesla Powerwall battery. The very first thing that I will point out is the security of our battery system. Fortress makes use of lithium iron phosphate chemistry in addition to being more safer than the Tesla Powerwall chemistry.
|No. of Parallel Stacking
|Guaranteed Battery Cycles
This safety also allows us to have extra power and longer duration which means, that we’ve a 40% more storage capability and a 100%, 40 p.c extra output, meaning that you just’re in a position to power more appliances to your longer amount of time.
Fortress Evault 18.5Kwh – Fortress gives a 10-year guarantee with around a 12 to 15-year lifespan whereas Tesla gives around half of that maybe six to seven, eight years of lifespan. Now, you are in all probability wondering how did you calculate this by way of security and longevity.
Fortress Power 5.4kW
We calculate this utilizing energy throughput. Energy throughput is the total amount of energy a battery will be expected to retailer and deliver over its lifetime. So, in case you see here the afford clear evil has 88.8 make watt-hours of energy throughput.
The assessments of Powerwall has solely 37.8 make numerous hours of energy throughput, most exhibiting that our battery just isn’t only safer but gonna final a heck of lots longer. And lastly, I’d like to deliver up the cost. So, you can see here, the fortress power system right here on the left, and the 2 Tesla Powerwall here on the right.
The installed cost of the fortress system is less than that of the Tesla Powerwall with a larger inverter but additionally has a for much longer energy throughput of 88.8 compared to 75.6. So, you’ll be able to see when we take this, and we get the cost per greenback per kilowatt-hour the fortress power system is actually extra environment friendly and higher by way of the dollars per kilowatt-hour that is being paid.

Fortress Evault Installation
1. Mounting and securing the battery
The Fortress eVault 18.5 is designed to stand on the floor with 4 wheels on the bottom. If desired, the wheels can be disassembled. We recommend putting the batteries on durable racks to avoid flooding. Please refer to the Fortress Lithium Battery Data Sheet for weight and dimension.
2. Mounting the battery pack to a wall
- Fasten the screws through the mounting brackets into the holes of the battery pack on both sides.
- Secure the mounting brackets to the wall with screws. Make sure to leave a space of
at last 2.18 inches in between the battery pack and the wall.
- Lock the rollers on the battery pack
3. Connecting the battery to the Charge Controller and/or Hybrid Inverter
The battery terminals are positioned under the top cover. Please use the screwdriver to take
the screws along the top cover off.
Please make sure the breaker near the terminal is in the OFF position. Please install the positive cable first and the negative cable second. Please do not cross the positive and negative terminals; also, ensure the terminals are not connected to any metal mounting, fixture, or body part. Recommended terminal torque is 7.0 – 7.7 Nm (5.1 – 5.7 ft-lb)
The Fortress Lithium Batteries are equipped with two M8 threaded terminals with a lock washer and nut. The right-hand stud resides in a red high-temperature molded insert. This connection is for the positive lead. The left-hand stud resides in a black high-temperature insert. This connection is for the negative lead. 8mm ring terminals along with proper size wiring cables are required to connect the battery to the inverter/charger. Do not reverse polarity, doing so will void the warranty. Use a voltmeter to check polarity before connecting terminals.
