Fortress Evault Review – Fortress battery techniques utilize the industry’s most environmentally benign chemistry- Lithium Ferro Phosphate, which eliminates operating temperature constraints, poisonous coolants, and the risk of thermal runaway and fireplace. The built-in smart Battery Management System (BMS) integrates multilevel security ideas: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Fortress Evault Review
Fortress high-performance Lithium Batteries are manufactured at the highest high quality normal. It comes with a big power capability and fast charging and steady 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, simple to put in, constantly reliable, and extremely efficient. It gives you the bottom lifetime energy cost
Reviews Fortress Power 18.5kWh
They have their own touchscreen show that provides 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 on the top. So, from the terminals on the battery, its overcurrent safety 250 amps out to the masses. You could immediately hook these as much as an inverter, or you might wire them to a high current bus, and parallel multiple batteries together to achieve an appropriate capability to your utility.
This battery is great for larger-scale off-grid purposes typically, the minimal obviously goes to be 18 kilowatt-hours. But, if you wish to have constructing blocks of 18-kilowatt-hour chunks, that’s the place this explicit battery is going to be finest suited.
Fortress eVault 18.5kWh
So, you recognize typically we’ll be utilizing these batteries for applications that are 30 kilowatt hours or extra, because of the significant constructing blocks as a result of the 18 kilowatt-hour capacity of every of those particular person banks.
Another cool characteristic of this battery is, that it’s on casters. So, it weighs about 400 pounds however shifting it around to the place its ultimate resting place is going to be is fairly easy with the casters. This explicit battery has knockouts on the perimeters. On both side, it lets you put in like a one-inch conduit, or one-inch string relief proper 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’ll point out is the protection of our battery system. Fortress makes use of lithium iron phosphate chemistry in addition to being more safer than the Tesla Powerwall chemistry.
|Specifications||Fortress Power||Tesla Powerwall|
|Usable Power||16,5||13.5 kWh|
|No. of Parallel Stacking||8||10|
|Guaranteed Battery Cycles||6.000||2.800|
|Continuous Power||8.2 KW||5 KW|
|Peak Output||12 kW||7 KW|
This security also permits us to have more power and longer length which means, that now we have a 40% extra storage capacity and a 100%, 40 p.c more output, which means that you simply’re in a position to power extra appliances to your longer period of time.
Fortress Evault Review – Fortress supplies a 10-year guarantee with round a 12 to 15-year lifespan whereas Tesla provides around half of that possibly six to seven, eight years of lifespan. Now, you are in all probability questioning how did you calculate this by way of safety and longevity.
Fortress Power 5.4kW
We calculate this using energy throughput. Energy throughput is the overall quantity of energy a battery will be anticipated to store and deliver over its lifetime. So, in the event you see here the afford transparent evil has 88.8 make watt-hours of energy throughput.
The checks of Powerwall has solely 37.8 make a variety of hours of energy throughput, most showing that our battery is not only safer however gonna last a heck of loads longer. And lastly, I’d like to carry up the cost. So, you may see here, the fortress power system right here on the left, and the two Tesla Powerwall right here on the appropriate.
The installed cost of the fortress system is lower than that of the Tesla Powerwall with a bigger inverter but in addition has a for much longer energy throughput of 88.8 in comparison to 75.6. So, you can see when we take this, and we get the cost per dollar per kilowatt-hour the fortress power system is definitely more efficient and better when it comes to 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.
