Solar Lithium Battery – Fortress battery systems make the most of the business’s most environmentally benign chemistry- Lithium Ferro Phosphate, which eliminates operating temperature constraints, poisonous coolants, and the risk of thermal runaway and fire. The built-in sensible Battery Management System (BMS) integrates multilevel safety concepts: Overcharge and Deep Discharge Protection; Voltage and Temperature Observation; Cell balancing.
Solar Lithium Battery
Fortress high-performance Lithium Batteries are manufactured on the highest high quality commonplace. It comes with a large power capability and fast charging and steady discharge power. The proprietary architecture and BMS eliminate the need for cooling or ventilation, which creates an efficient round-trip conversion.
The Fortress Lithium Battery is protected, straightforward to put in, consistently reliable, and highly efficient. It offers you the bottom lifetime energy cost
Reviews Fortress Power 18.5kWh
They have their own touchscreen show 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 on the top. So, from the terminals on the battery, its overcurrent protection 250 amps out to the loads. You may immediately hook these as much as an inverter, or you can wire them to a high current bus, and parallel a number of batteries collectively to realize a suitable capability on your utility.
This battery is great for larger-scale off-grid applications typically, the minimum obviously goes to be 18 kilowatt-hours. But, if you wish 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 already know usually we’ll be using these batteries for functions that are 30 kilowatt hours or extra, due to the significant constructing blocks on account of the 18 kilowatt-hour capacity of every of these individual banks.
Another cool function of this battery is, that it’s on casters. So, it weighs about 400 pounds however shifting it round to where its remaining resting place is going to be is fairly simple with the casters. This specific battery has knockouts on the edges. On both aspect, it permits you to put in like a one-inch conduit, or one-inch string relief right 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 makes use of lithium iron phosphate chemistry along with being more 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 security additionally allows us to have more power and longer length that means, that we now have a 40% extra storage capability and a 100%, 40 p.c extra output, which means that you’re in a position to power extra appliances for your longer amount of time.
Solar Lithium Battery – Fortress gives a 10-year warranty with round a 12 to 15-year lifespan whereas Tesla gives round half of that maybe six to seven, eight years of lifespan. Now, you are probably wondering 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 quantity of energy a battery can be expected to retailer and deliver over its lifetime. So, if you see here the afford clear evil has 88.8 make watt-hours of energy throughput.
The tests of Powerwall has solely 37.8 make a variety of hours of energy throughput, most showing that our battery is not only safer but gonna final a heck of quite a bit longer. And lastly, I’d wish to bring up the cost. So, you possibly can see here, the fortress power system right here on the left, and the 2 Tesla Powerwall here on the correct.
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 in comparison to 75.6. So, you’ll be able to see after we take this, and we get the cost per greenback per kilowatt-hour the fortress power system is actually extra efficient and higher by way 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.
