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 out and in 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 may instantly hook these as much as an inverter, or you might wire them to a excessive current bus, and parallel multiple batteries together to gain a suitable capacity for your utility.
This battery is nice for larger-scale off-grid applications usually, the minimum clearly goes to be 18 kilowatt-hours. But, if you wish to have constructing 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 usually we’ll be using these batteries for functions which might be 30 kilowatt hours or extra, due to the significant building blocks as a result of the 18 kilowatt-hour capability of each of these individual banks.
Another cool feature of this battery is, that it’s on casters. So, it weighs about 400 pounds however moving it round to the place its last resting place goes to be is pretty straightforward with the casters. This particular battery has knockouts on the edges. On either facet, it means that you can 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 mention is the safety of our battery system. Fortress uses lithium iron phosphate chemistry along with 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 also allows us to have more power and longer length meaning, that we now have a 40% more storage capability and a 100%, 40 percent more output, that means that you simply’re capable of power extra home equipment on your longer period of time.
Fortress Evault 18.5 – Fortress supplies a 10-year warranty with around a 12 to 15-year lifespan whereas Tesla supplies around half of that possibly six to seven, eight years of lifespan. Now, you’re in all probability wondering 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 entire quantity of energy a battery will be anticipated to store and deliver over its lifetime. So, should you see right here the afford clear evil has 88.8 make watt-hours of energy throughput.
The tests of Powerwall has only 37.8 make plenty of hours of energy throughput, most displaying that our battery is just not solely safer but gonna final a heck of rather a lot longer. And lastly, I’d prefer to carry up the cost. So, you may see here, the fortress power system here on the left, and the two Tesla Powerwall right here on the precise.
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 greenback per kilowatt-hour the fortress power system is actually more efficient and higher 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.
