Reviews Fortress Power 18.5kWh
They have their 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 loads. You may straight hook these up to an inverter, or you possibly can wire them to a excessive current bus, and parallel a number of batteries together to achieve an acceptable capacity on your software.
This battery is great for larger-scale off-grid functions usually, 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 explicit battery goes to be finest suited.
Fortress eVault 18.5kWh
So, you recognize usually we’ll be utilizing these batteries for applications that are 30 kilowatt hours or extra, because of the numerous constructing blocks as a result of the 18 kilowatt-hour capacity of every of these particular person banks.
Another cool characteristic of this battery is, that it’s on casters. So, it weighs about 400 pounds but transferring it around to the place its closing resting place is going to be is pretty simple with the casters. This specific battery has knockouts on the sides. On either side, it means that you can put in like a one-inch conduit, or one-inch string relief 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 safety of our battery system. Fortress makes use of 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 safety also permits us to have more power and longer length meaning, that we have a 40% more storage capability and a 100%, 40 % more output, which means that you simply’re capable of power more appliances to your longer amount of time.
Fortress Evault 18.5 Kwh Lithium Battery – Fortress gives a 10-year warranty with round a 12 to 15-year lifespan while Tesla provides around half of that perhaps six to seven, eight years of lifespan. Now, you’re probably questioning how did you calculate this by way of safety and longevity.
Fortress Power 5.4kW
We calculate this utilizing energy throughput. Energy throughput is the full amount of energy a battery will be expected to store and ship over its lifetime. So, in the event you see here the afford transparent evil has 88.8 make watt-hours of energy throughput.
The tests of Powerwall has solely 37.8 make a lot of hours of energy throughput, most exhibiting that our battery isn’t solely safer however gonna last a heck of quite a bit 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 2 Tesla Powerwall right here on the fitting.
The put in cost of the fortress system is lower 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 after we take this, and we get the cost per dollar per kilowatt-hour the fortress power system is actually 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.
