Introducing the Dakota Lithium Home Backup Power & Solar Energy Storage System—your ultimate solution for uninterrupted power during extended outages. Whether you're looking to go fully off-grid or need reliable backup for your essential electronics, this system is designed for flexibility and high performance. With stackable batteries offering 5-20 kWh of power and a robust 3,000W inverter, it adapts to your home’s unique energy needs.

5kwh is ideal for small off grid applications like tiny homes, small cabins, boats or RVs. Or backup power for your essential electronics. 10 - 15 kwhs (2 - 3 batteries) is optimal for keeping key appliances like refrigerators and freezers running smoothly during an extended power outage. And 20 kwh (4 batteries) is the ideal size for most homes, giving you power outage protection and a clean, quiet, and healthy alternative to traditional generators. For homes with rooftop solar panels 20kwh is recommended to maximize your solar energy storage.

Built Dakota tough, this system includes Dakota Lithium Stackable 48V 100Ah Batteries and a stackable 3,000 watt inverter. Each battery has twice the power, half the weight, and 10X the lifespan and reliability of traditional batteries. Backed up by a 11 year replacement warranty guarantee. Built from Dakota Lithium's signature iron phosphate technology, the Dakota Lithium Home Backup Power & Energy Storage System adopts a modular design with a battery and inverter that stack on top of each other and are easy to wire together.

Each battery is integrated with an intelligent BMS system, making it easy to expand and can be combined into up to 20.48KWh of battery capacity. The BMS uses a professional protection board testing system to conduct comprehensive testing before going online, ensuring that the BMS provides comprehensive and effective protection for the battery during use. 

Included is a Dakota Lithium Off-Grid 3000KWh Inverter with MPPT controller. The inverter stacks on top of the battery and features advanced MPPT technology to maximize solar energy, a display screen and indicator light that dynamically displays system data and operating status, reduces no-load losses in power-saving mode, utilizes adjustable speed fans for efficient heat dissipation, and has comprehensive protection functions. The battery stores the energy,. The inverter connects the battery to your home and the MPPT controller gives the option to connect the system to rooftop solar panels.

Specifications

Storage Capacity

100Ah. Dakota Lithium batteries provide consistent power for all 100 Amp hours. DL LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized lead acid batteries. You get all the juice down to the last drop.

Energy

5,120 Watt-hours (Wh). 5.1Kwh per battery. Stack 4 units in parallel for 20Kwh.

Voltage

51.2V

Lifecycles

Up to 80% capacity for 5,000 cycles in recommended conditions. The typical SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries. 

11 Year Warranty

Industry leading, best in class 11 year warranty.

Frequently Asked Questions

TWICE THE POWER?

Yes! Here at Dakota Lithium we build all of our batteries with lithium iron phosphate technology which has many distinct advantages over traditional batteries. Including 60% less weight, a charging speed that is up to 5X faster, and a significantly longer lifespan (5-10 years longer on average). One of the most noticeable advantages however is the flat voltage curve. Unlike a lead acid battery where the voltage drops as you use the battery a Dakota Lithium battery has a steady voltage for 99% of the battery's charge. That means you get all the power down to the last drop and double the usable power of traditional batteries.

ARE LITHIUM BATTERIES SAFE?

Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Dakota Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don't submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.

HOW DO I CHARGE A LITHIUM BATTERY?

Dakota Lithium batteries perform best when charged by a lithium compatible charger. Lead acid or SLA chargers, on-board chargers for AGM batteries, or other non-lithium chargers will charge a Dakota Lithium battery but only to 70-80% of capacity. This is because Dakota Lithium iron phosphate (LiFePO4) technology charges and is full at a higher voltage then traditional batteries (Dakota Lithium charges at 14.4 Volts). Chargers with a lithium battery setting or designed for lithium will charge at the appropriate voltage.  For troubleshooting tips download the Dakota Lithium battery user manual here.

WILL COLD WEATHER AFFECT MY BATTERY?

Your Dakota Lithium battery will discharge normally between a range of -20F and 120F (-29C to 49C). DL batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter).
