The D7680 is the first and largest of our personal mobile units we're introducing and is a workhorse for almost any application. From large to small electrical draws, this powerhouse contains 7680kwh.


Whether it's residential, construction site needs, mobility for farm and ranch, loss of electricity and more! This is a great resource for practically any situation and power longevity depending on draw.

Highlights of the D7680

Accessibility

We produce units that give the user total access. This means as time goes by and internal components wear out, depending on usage, you have the ability to change parts and keep going with your original box. This may not be the case with other industry products, as many are sealed and offer no access when components fail over time. Or, warranties have either expired or if something fails during that period, you have to send it back and be without your power needs.

Lifepo4 battery power! This unit holds up to six 1280kwh, 100ah batteries each and will deliver the power you need. Our design also gives you the flexibility of removing and adding batteries when it comes to it. Oh! Nothing meek and weak about our units! Not only housed by a strong exterior, it's interior is designed the same. It is skirted with a metal railing frame that not only lends inward skeletal strength, but holds valuable components firmly in place.

MPPT Charger

Power Inverter

An MPPT Dc to DC charger is important when it comes to charging and transferring the power you need to keep your batteries charged. It's versatility also enables it to be charged via Lifepo4 battery charger, solar panels and by automobile, which some chargers do not allow. These types of charges are the only type we install in our units. The unique design of our products means each unit can hold a different size MPPT charger with higher or lower transfer capacity.

A powerful inverter is important when it comes to delivering electricity to appliances, equipment and more. A unique feature of our units is that each one can be fitted with a more powerful inverter based on our interior rail design. That's versatility! Each one also comes with a visual LCD display and remote so you know what your battery bank has stored at all times. Unique features include 110 outlets, remote module connection, ac terminal block and USB ports.

Safety is important! All of our units that have electrical plugs are protected with covers to ensure your safety from shock from the inverter a/c terminal block. However, electrical connections should be disconnected before any repairs are made. We also did not skimp on wiring. Each unit produced is designed with 4 gage copper wire. This ensures the best electrical current flow of transferring the most power from the unit to the application and inbound charging flow.
