Fortress Evault Manual – Fortress battery systems 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 hearth. The built-in good Battery Management System (BMS) integrates multilevel security ideas: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Fortress Evault Manual
Fortress high-performance Lithium Batteries are manufactured on the highest high quality customary. It comes with a big power capability and fast charging and steady discharge power. The proprietary structure and BMS eliminate the necessity for cooling or air flow, which creates an efficient round-trip conversion.
The Fortress Lithium Battery is secure, easy to put in, constantly dependable, and highly efficient. It provides you the lowest lifetime energy cost
Reviews Fortress Power 18.5kWh
They have their very own touchscreen show that gives 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 hundreds. You might immediately hook these up to an inverter, or you could possibly wire them to a high current bus, and parallel multiple batteries collectively to gain an acceptable capacity on your application.
This battery is nice for larger-scale off-grid applications typically, the minimum obviously is going to be 18 kilowatt-hours. But, if you wish to have constructing blocks of 18-kilowatt-hour chunks, that’s where this specific battery goes to be greatest suited.
Fortress eVault 18.5kWh
So, you already know sometimes we’ll be using these batteries for applications which can be 30 kilowatt hours or more, because of the numerous constructing blocks on account of the 18 kilowatt-hour capability of each of those particular person banks.
Another cool feature of this battery is, that it’s on casters. So, it weighs about 400 pounds but transferring it around to the place its ultimate resting place goes to be is fairly straightforward with the casters. This specific battery has knockouts on the sides. On both aspect, 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 will mention is the safety of our battery system. Fortress uses lithium iron phosphate chemistry in addition to being more safer than the Tesla Powerwall chemistry.
| Specifications | Fortress Power | Tesla Powerwall |
|---|---|---|
| Battery Chemistry | LFP | NMC |
| Safety | Yes | No |
| Usable Power | 16,5 | 13.5 kWh |
| No. of Parallel Stacking | 8 | 10 |
| Guaranteed Battery Cycles | 6.000 | 2.800 |
| LCD Display | Yes | x |
| Continuous Power | 8.2 KW | 5 KW |
| Peak Output | 12 kW | 7 KW |
This security additionally permits us to have extra power and longer duration meaning, that now we have a 40% extra storage capability and a 100%, 40 percent extra output, meaning that you’re capable of power more home equipment for your longer period of time.
Fortress Evault Manual – Fortress provides a 10-year guarantee with round a 12 to 15-year lifespan whereas Tesla offers around half of that perhaps six to seven, eight years of lifespan. Now, you’re in all probability questioning how did you calculate this in terms of safety and longevity.
Fortress Power 5.4kW
We calculate this using energy throughput. Energy throughput is the full amount of energy a battery may be expected to store and deliver over its lifetime. So, when you see right here the afford clear evil has 88.8 make watt-hours of energy throughput.
The checks of Powerwall has solely 37.8 make loads of hours of energy throughput, most showing that our battery will not be only safer however gonna last a heck of a lot longer. And lastly, I’d wish to bring up the cost. So, you can see here, the fortress power system right here on the left, and the 2 Tesla Powerwall right here on the precise.
The put in cost of the fortress system is less than that of the Tesla Powerwall with a larger inverter but also has a for much longer energy throughput of 88.8 in comparison to 75.6. So, you’ll be able to see when we take this, and we get the cost per dollar per kilowatt-hour the fortress power system is definitely extra environment friendly and better in terms of 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.
