Fortress Evault Battery – Fortress battery methods utilize the business’s most environmentally benign chemistry- Lithium Ferro Phosphate, which eliminates operating temperature constraints, toxic coolants, and the chance of thermal runaway and fire. The built-in good Battery Management System (BMS) integrates multilevel safety concepts: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Fortress Evault Battery
Fortress high-performance Lithium Batteries are manufactured at the highest quality standard. It comes with a large power capability and quick charging and continuous discharge power. The proprietary architecture and BMS remove the need for cooling or air flow, which creates an efficient round-trip conversion.
The Fortress Lithium Battery is safe, straightforward to install, constantly reliable, and extremely environment friendly. It supplies you the bottom lifetime energy cost
Reviews Fortress Power 18.5kWh
They have their very 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 masses. You could directly hook these up to an inverter, or you can wire them to a high current bus, and parallel a number of batteries collectively to realize a suitable capability in your software.
This battery is great for larger-scale off-grid applications typically, the minimal clearly goes to be 18 kilowatt-hours. But, if you want to have building blocks of 18-kilowatt-hour chunks, that’s the place this explicit battery goes to be finest suited.
Fortress eVault 18.5kWh
So, usually we’ll be using these batteries for purposes that are 30 kilowatt hours or extra, because of the significant constructing blocks because of the 18 kilowatt-hour capacity of every of those particular person banks.
Another cool feature of this battery is, that it’s on casters. So, it weighs about 400 pounds however shifting it around to where its closing resting place is going to be is fairly simple with the casters. This particular battery has knockouts on the sides. On either side, it lets you put in like a one-inch conduit, or one-inch string reduction proper into the battery.

Fortress Power VS Tesla Powerwall
Comparison between the Fortress power battery and the Tesla Powerwall battery. The first thing that I’ll point out is the protection of our battery system. Fortress uses lithium iron phosphate chemistry in addition to being more safer than the Tesla Powerwall chemistry.
|No. of Parallel Stacking
|Guaranteed Battery Cycles
This security also allows us to have extra power and longer duration that means, that we have now a 40% more storage capability and a 100%, 40 p.c extra output, meaning that you just’re capable of power extra home equipment on your longer amount of time.
Fortress Evault Battery – Fortress gives a 10-year warranty with around a 12 to 15-year lifespan whereas Tesla provides around half of that perhaps six to seven, eight years of lifespan. Now, you are most likely wondering 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 whole amount of energy a battery might be expected to store and ship over its lifetime. So, if you happen to see right here the afford clear evil has 88.8 make watt-hours of energy throughput.
The assessments of Powerwall has solely 37.8 make lots of hours of energy throughput, most displaying that our battery isn’t solely safer however gonna last a heck of quite a bit longer. And lastly, I’d prefer to bring up the cost. So, you may see right here, the fortress power system here on the left, and the 2 Tesla Powerwall here on the best.
The put in cost of the fortress system is less than that of the Tesla Powerwall with a larger inverter but in addition has a much longer energy throughput of 88.8 in comparison to 75.6. So, you’ll be able to see once we take this, and we get the cost per dollar per kilowatt-hour the fortress power system is definitely extra efficient and better in terms 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.
