Reviews Fortress Power 18.5kWh
They have their very own touchscreen show that provides 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 hundreds. You may instantly hook these up to an inverter, or you could possibly wire them to a excessive current bus, and parallel a number of batteries collectively to achieve an acceptable capacity in your software.
This battery is nice for larger-scale off-grid purposes sometimes, the minimum obviously goes to be 18 kilowatt-hours. But, if you want to have building blocks of 18-kilowatt-hour chunks, that’s the place this specific battery is going to be best suited.
Fortress eVault 18.5kWh
So, you know usually we’ll be using these batteries for functions which are 30 kilowatt hours or extra, because of the significant building blocks as a result of the 18 kilowatt-hour capability of every of those particular person banks.
Another cool characteristic of this battery is, that it’s on casters. So, it weighs about 400 pounds however shifting it around to the place its ultimate resting place goes to be is fairly straightforward with the casters. This particular battery has knockouts on the sides. On both facet, it means that you can put in like a one-inch conduit, or one-inch string aid right 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 security of our battery system. Fortress makes use of lithium iron phosphate chemistry in addition to being extra safer than the Tesla Powerwall chemistry.
|Specifications||Fortress Power||Tesla Powerwall|
|Usable Power||16,5||13.5 kWh|
|No. of Parallel Stacking||8||10|
|Guaranteed Battery Cycles||6.000||2.800|
|Continuous Power||8.2 KW||5 KW|
|Peak Output||12 kW||7 KW|
This safety additionally permits us to have extra power and longer duration meaning, that we've got a 40% extra storage capability and a 100%, 40 percent more output, which means that you just're in a position to power more home equipment in your longer period of time.
Fortress Evault 18.5Kwh Lithium Battery - Fortress provides a 10-year warranty with round a 12 to 15-year lifespan whereas Tesla supplies around half of that maybe six to seven, eight years of lifespan. Now, you are probably wondering how did you calculate this when it comes to safety and longevity.
Fortress Power 5.4kW
We calculate this using energy throughput. Energy throughput is the entire quantity of energy a battery may be anticipated to store and deliver over its lifetime. So, in the event you see right here the afford clear evil has 88.8 make watt-hours of energy throughput.
The assessments of Powerwall has only 37.8 make plenty of hours of energy throughput, most displaying that our battery isn't only safer however gonna final a heck of lots longer. And lastly, I'd wish to carry up the cost. So, you'll be able to see here, the fortress power system here on the left, and the 2 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'll be able to see when we take this, and we get the cost per greenback per kilowatt-hour the fortress power system is actually more environment friendly 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.
