Lithium Battery – Fortress battery methods make the most of the industry’s most environmentally benign chemistry- Lithium Ferro Phosphate, which eliminates operating temperature constraints, toxic coolants, and the danger of thermal runaway and hearth. The built-in smart Battery Management System (BMS) integrates multilevel safety concepts: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Fortress high-performance Lithium Batteries are manufactured at the highest quality standard. It comes with a large power capability and fast charging and steady discharge power. The proprietary architecture and BMS eliminate the necessity for cooling or air flow, which creates an efficient round-trip conversion.
The Fortress Lithium Battery is protected, easy to put in, constantly reliable, and highly efficient. It gives you the lowest lifetime energy cost
Reviews Fortress Power 18.5kWh
They have their very own touchscreen show 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 on the top. So, from the terminals on the battery, its overcurrent protection 250 amps out to the loads. You could immediately hook these up to an inverter, or you may wire them to a high current bus, and parallel a number of batteries collectively to realize a suitable capability in your utility.
This battery is great for larger-scale off-grid applications usually, the minimum 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 greatest suited.
Fortress eVault 18.5kWh
So, you understand typically we’ll be using these batteries for applications which might be 30 kilowatt hours or more, due to the numerous building blocks because of the 18 kilowatt-hour capacity of each of those individual banks.
Another cool characteristic of this battery is, that it’s on casters. So, it weighs about 400 pounds however transferring it around to where its last resting place is going to be is pretty easy with the casters. This particular battery has knockouts on the edges. On either aspect, it lets you put in like a one-inch conduit, or one-inch string aid 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 will point out is the safety of our battery system. Fortress uses lithium iron phosphate chemistry along with being extra safer than the Tesla Powerwall chemistry.
|No. of Parallel Stacking
|Guaranteed Battery Cycles
This security also allows us to have extra power and longer period meaning, that we now have a 40% extra storage capability and a 100%, 40 percent extra output, which means that you’re in a position to power extra home equipment to your longer period of time.
Lithium Battery – Fortress gives a 10-year guarantee with around a 12 to 15-year lifespan whereas Tesla gives round half of that maybe six to seven, eight years of lifespan. Now, you’re probably questioning how did you calculate this when it comes to security and longevity.
Fortress Power 5.4kW
We calculate this using energy throughput. Energy throughput is the entire amount of energy a battery may be anticipated to retailer and deliver over its lifetime. So, if you see right here the afford transparent evil has 88.8 make watt-hours of energy throughput.
The checks of Powerwall has solely 37.8 make numerous hours of energy throughput, most showing that our battery is just not solely safer however gonna last a heck of lots longer. And lastly, I’d like to bring up the cost. So, you may see right here, the fortress power system here on the left, and the two Tesla Powerwall here on the correct.
The put in cost of the fortress system is less than that of the Tesla Powerwall with a bigger inverter but additionally has a much longer energy throughput of 88.8 in comparison to 75.6. So, you possibly can see once we take this, and we get the cost per greenback per kilowatt-hour the fortress power system is actually more efficient and better when it comes to the dollars per kilowatt-hour that’s 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.
