Off Grid Solar Battery
Fortress high-performance Lithium Batteries are manufactured on the highest quality commonplace. It comes with a big power capacity and quick charging and continuous discharge power. The proprietary structure and BMS get rid of the need for cooling or air flow, which creates an efficient round-trip conversion.
The Fortress Lithium Battery is secure, straightforward to put in, consistently dependable, and extremely environment friendly. It offers you the lowest lifetime energy cost
Reviews Fortress Power 18.5kWh
They have their own touchscreen display 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 protection 250 amps out to the masses. You may directly hook these up to an inverter, or you possibly can wire them to a high current bus, and parallel a number of batteries together to gain an appropriate capacity to your application.
This battery is nice for larger-scale off-grid purposes usually, the minimal 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 greatest suited.
Fortress eVault 18.5kWh
So, you understand sometimes we’ll be utilizing these batteries for purposes which can be 30 kilowatt hours or extra, because of the numerous constructing blocks on account 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 moving it around to the place its closing resting place goes to be is pretty simple with the casters. This specific battery has knockouts on the perimeters. On either facet, it lets you 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 first thing that I will mention 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 |
|---|---|---|
| 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 additionally allows us to have more power and longer duration which means, that we have a 40% extra storage capability and a 100%, 40 p.c extra output, that means that you just’re able to power extra appliances on your longer amount of time.
Off Grid Solar Battery – Fortress supplies a 10-year guarantee with around a 12 to 15-year lifespan while Tesla offers 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 security and longevity.
Fortress Power 5.4kW
We calculate this utilizing energy throughput. Energy throughput is the whole quantity of energy a battery can be anticipated to store and ship over its lifetime. So, should you see right here the afford clear evil has 88.8 make watt-hours of energy throughput.
The exams of Powerwall has only 37.8 make quite a lot of hours of energy throughput, most showing that our battery is not only safer but gonna last a heck of so much longer. And lastly, I’d like to bring up the cost. So, you may see here, the fortress power system right here on the left, and the two Tesla Powerwall right here on the suitable.
The put in cost of the fortress system is lower than that of the Tesla Powerwall with a larger inverter but also 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 definitely extra 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.
