Fortress Lithium Battery – Fortress battery systems utilize the business’s most environmentally benign chemistry- Lithium Ferro Phosphate, which eliminates operating temperature constraints, toxic coolants, and the risk of thermal runaway and hearth. The built-in smart Battery Management System (BMS) integrates multilevel security concepts: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Fortress Lithium Battery
Fortress high-performance Lithium Batteries are manufactured on the highest high quality standard. It comes with a big power capacity and fast charging and continuous discharge power. The proprietary structure and BMS remove the necessity for cooling or air flow, which creates an environment friendly round-trip conversion.
The Fortress Lithium Battery is safe, easy to install, constantly dependable, and extremely environment friendly. It supplies 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 at the top. So, from the terminals on the battery, its overcurrent safety 250 amps out to the masses. You might immediately hook these up to an inverter, or you could wire them to a excessive current bus, and parallel a number of batteries together to realize a suitable capacity to your utility.
This battery is nice for larger-scale off-grid purposes typically, the minimum clearly is going to be 18 kilowatt-hours. But, if you want to have constructing blocks of 18-kilowatt-hour chunks, that’s the place this specific battery goes to be finest suited.
Fortress eVault 18.5kWh
So, you know usually we’ll be using these batteries for purposes that are 30 kilowatt hours or more, due to the significant building blocks because of the 18 kilowatt-hour capability of each of these particular person banks.
Another cool feature of this battery is, that it’s on casters. So, it weighs about 400 pounds but moving it round to where its remaining resting place is going to be is fairly easy with the casters. This specific battery has knockouts on the sides. On both side, it allows you to 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 along with being extra 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 safety also allows us to have extra power and longer duration meaning, that we’ve got a 40% more storage capacity and a 100%, 40 p.c more output, that means that you simply’re able to power more appliances in your longer period of time.
Fortress Lithium Battery – Fortress offers a 10-year warranty with around a 12 to 15-year lifespan whereas Tesla offers round half of that perhaps six to seven, eight years of lifespan. Now, you are in all probability wondering how did you calculate this when it comes to safety and longevity.
Fortress Power 5.4kW
We calculate this utilizing energy throughput. Energy throughput is the entire quantity of energy a battery will be expected to store and deliver over its lifetime. So, if you see here the afford clear 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 exhibiting that our battery shouldn’t be only safer but gonna final a heck of quite a bit longer. And lastly, I’d prefer to carry up the cost. So, you possibly can see right here, the fortress power system here on the left, and the 2 Tesla Powerwall right here on the proper.
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 compared to 75.6. So, you can see once we take this, and we get the cost per greenback per kilowatt-hour the fortress power system is actually more environment friendly 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.
