Secure Your Force 15k Energy Storage System Today!

In a breakthrough move for 2024, we present the FORCE 15K – the inaugural lithium iron phosphate power station by Mammoth RE that genuinely powers your entire home or off-grid property. Boasting more capacity than 4 x Bluetti AC300's and 15% more capacity than a Tesla Powerwall, all at a remarkable 50% of the cost.

Triggered by an overwhelming response from our customers and a deep dive into existing products, we discovered a gaping hole in the market. Enter the FORCE 15K – born out of your requests, submissions, and support calls. We've taken everything there is to love about power stations and obliterated the issues: limited capacity, restrained power output, and unnecessary complexity. Unlike other units that claim to power your entire house with one unit but fall short in reality, the FORCE 15K is here to close that gap.

A unique feature that defines the FORCE 15K is its built-in split-phase output. Uncommon in products of its kind, this design ensures a seamless distribution of power, catering to a variety of applications. From powering delicate electronics to handling heavy-duty equipment, the FORCE 15K delivers 8,000W of consistent and reliable energy output at either 120V or 240V.

How does the warranty work?

Each unit is backed by a standard 10-year manufacturer warranty from the date of shipment. The average lifespan of a lithium battery at 90% Depth of Discharge is between 3,000 – 6,000 lifecycles or roughly 5 to 10 years of standard daily use (many more years if used only in backup and recreational situations).

This warranty does not cover negligence or misuse of the battery or the normal wear and tear. If it is deemed that the battery was used improperly, you will be subject to a $150 an hour repair charge plus parts and shipping.

To submit a warranty claim, please contact us directly at support@shopsolar.com. The battery may be required to be shipped back to one of our US warehouse locations for further inspection.

How heavy is the unit?

The unit weighs a total of 395 lbs, however to make moving it easier, we have designed a 2-piece system where you can remove the top inverter portion from the bottom battery portion.

The top weighs approximately 165 lbs, the bottom piece weighs 230 lbs and has wheels for easy maneuverability.

How does the top connect to the bottom?

The top and bottom are held together with screw-on plates on either side of the unit and connect via a standard SB175 cable which you can see in the product images.

How quickly can it recharge?

You can recharge the unit from 0-100% with up to 4,000W of solar panels in approximately 4 hours. You can also use both 240V and 120V AC power to recharge the unit. 

240V power will recharge the unit much faster than the 120V wall charger included with your order, but we highly recommend “slow” charging the unit from AC power whenever possible to preserve the longevity of the battery.

You can recharge the unit from solar and AC power at the same time.

Is the Force 15k UL Listed?

The Force 15K ESS is not UL Listed as this is not required for off-grid applications, portable power stations and solar generators. You will not be selling excess power back to the grid with a unit like this, you will be securing your energy independence and investing in a clean, quiet, reliable source of power for years to come.

What is the continuous AC output?

The continuous AC output of the unit is 8,000W at either 120V or 240V. Most appliances you will be running are 120V however things like well pumps, dryers, and some larger AC units require 240V output which the Force 15K can easily handle.

How quiet is the Force 15K?

The FORCE 15K Solar Power Station operates at an impressive 50 decibels during both standard operation and charging, ensuring a remarkably quiet environment. Multiple decibel rating reports reveals that, even at peak output, it maintains a range of 75-85 decibels—very comparable to the quiet performance of many solar generators and power stations on the market today.

Decent system

Got the system, charged it up via AC, then tested it with the solar panels also got. Some aspects missing from the manual but quite easy and support were good at answering my questions. Tested it out and it ran my back up critical circuit perfectly. Compact and it works.

Am still waiting for the expansion battery, which was a selling point. Then it will be damn near perfect.
