Fortress Power – Fortress battery techniques utilize the industry’s most environmentally benign chemistry- Lithium Ferro Phosphate, which eliminates operating temperature constraints, poisonous coolants, and the danger of thermal runaway and hearth. The built-in sensible Battery Management System (BMS) integrates multilevel safety ideas: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Fortress high-performance Lithium Batteries are manufactured on the highest high quality commonplace. It comes with a big power capacity and fast charging and continuous discharge power. The proprietary architecture and BMS eliminate the necessity for cooling or air flow, which creates an environment friendly round-trip conversion.
The Fortress Lithium Battery is safe, easy to put in, constantly reliable, and highly environment friendly. It offers you the lowest 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 on the top. So, from the terminals on the battery, its overcurrent safety 250 amps out to the loads. You may directly hook these up to an inverter, or you could wire them to a high current bus, and parallel a number of batteries collectively to achieve a suitable capacity in your software.
This battery is nice for larger-scale off-grid applications sometimes, the minimal obviously goes to be 18 kilowatt-hours. But, if you want to have constructing blocks of 18-kilowatt-hour chunks, that’s where this specific battery is going to be best suited.
Fortress eVault 18.5kWh
So, you understand typically we’ll be using these batteries for functions which might be 30 kilowatt hours or more, due to the numerous constructing blocks because of the 18 kilowatt-hour capability of every of those individual banks.
Another cool feature of this battery is, that it’s on casters. So, it weighs about 400 pounds however shifting it round to where its last resting place is going to be is fairly simple with the casters. This specific battery has knockouts on the perimeters. On either side, it lets you put in like a one-inch conduit, or one-inch string relief 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 mention is the safety of our battery system. Fortress uses lithium iron phosphate chemistry in addition to being extra safer than the Tesla Powerwall chemistry.
|No. of Parallel Stacking
|Guaranteed Battery Cycles
This safety additionally allows us to have extra power and longer length meaning, that we have a 40% extra storage capacity and a 100%, 40 p.c extra output, meaning that you simply’re able to power more appliances on your longer period of time.
Fortress Power – Fortress gives a 10-year guarantee with around a 12 to 15-year lifespan whereas Tesla provides round half of that possibly six to seven, eight years of lifespan. Now, you are most likely wondering how did you calculate this by way of security and longevity.
Fortress Power 5.4kW
We calculate this using energy throughput. Energy throughput is the overall amount of energy a battery may be expected to store and deliver over its lifetime. So, for those who see right here the afford clear evil has 88.8 make watt-hours of energy throughput.
The checks of Powerwall has only 37.8 make quite a lot of hours of energy throughput, most exhibiting that our battery is not solely safer but gonna last a heck of rather a lot longer. And lastly, I’d like to convey up the cost. So, you possibly can 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 less than that of the Tesla Powerwall with a bigger inverter but in addition has a for much longer energy throughput of 88.8 compared to 75.6. So, you possibly can see when we take this, and we get the cost per dollar per kilowatt-hour the fortress power system is actually extra efficient and higher 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.
